I replaced all the struts, the front left wheel bearing, and all front upper control arms on my vehicle a few months ago.

In the process of that work, I found that both front upper control arm pinch bolts had completely fused with the knuckles. I had to drill them out, somewhat crudely, to accomplish my tasks... and I eventually determined that the knuckles were compromised, so I replaced both knuckles as well.

All of these new parts were cheap aftermarket parts. (I could not justify OEM on an almost 200k Audi.)

The wiring to the front wheel speed sensors undoubtedly took a beating throughout this process.

After doing this work, I had warning lights, beeps, and code 00285 - ABS Wheel Speed Sensor; Front Right (G45) 003 - Mechanical Failure. After awhile of driving, the parking brake and engine modules would also throw codes, basically just saying to check the ABS memory for faults.

Driving the car around with VCDS on, and watching the speed sensors, I found that the reported front right wheel speed mostly matched the other wheels, but would briefly drop every second or two. So for example, if I was driving at 20 mph, all wheels would read 20 (or 19, or 21), but every second or two the front right would flicker and drop to, say, 5 or something. And then it would recover to match the other wheel speeds.

I'd already replaced the front left bearing. And I knew that I'd bashed the bearings enough during the suspension work that I might have messed up the tone ring on the front right, as well. So I ordered another wheel bearing (from same provider as the one I put on the front left). I also ordered a cheap ABS sensor.

I put the new wheel bearing on the front right. It went in fine. (The old bearing's tone ring did look fairly rough.) I also put the new ABS sensor in the front right. Unfortunately, I'm still having the same problems.

Here's all that I've done to troubleshoot this:

1. Replaced front right wheel bearing. It's cheap, but from same place the other (working) bearing came from, and it seems sound when I inspect it
2. Replaced front right wheel speed sensor. Again: cheap, but it's getting about the same readings as the previous one did
3. Cut away the connector to the ABS sensor, and wired it directly in, thinking that the connector or the wire right near the sensor was the issue. Didn't change anything
4. Unplugged the wheel speed sensor entirely, to verify that the code changes. It does indeed change to an Open Circuit instead of Mechanical Failure code when unplugged. (Though shorting the wires doesn't seem to make it report as a short. I'm thinking that's just due to some detail of how the sensor works.)
5. Removed the new bearing again, and cleaned the tone ring, the wheel speed sensor, the hole the sensor goes in, and everything around it in case there were metal shavings or some such interfering with the sensor. It was fairly dirty, but the cleaning solved nothing.

So... at this point, I'm kind of losing my mind. I realize that installing OEM parts will be a suggestion, but I can't justify it on a vehicle with this age and mileage. But I *would* like to make this work, safely, because the body and interior of the car are still great.

It seems to me that a bad sensor would be most likely to either show no wheel speed, or infinite wheel speed, or just be *wrong* most of the time, instead of being *mostly* right, but then giving these intermittent speed drops.

Same for wiring... I'd expect it to maybe drop out periodically if a wire is twisting around and losing connection... but not with this sort of consistency.

The regular drops in reported wheel speed *still* seem consistent with a tone ring problem. (The reported speed would logically drop when the damaged part of the tone ring moves past the sensor.) But, man... what are the odds that I'd have the exact same problem with the new bearing/tone ring, as I had with the old bearing/tone ring?

I considered that the cheap knuckles might possibly be making the sensor sit wrong, in relation to the bearing, if the positions of the holes are a little off. But, if that were the case, I wouldn't expect the speed numbers to be mostly right. (And the bearing should be presenting about the same distance from the sensor, regardless of where the wheel is in its actual rotation, so this cyclical fluctuation in wheel speed wouldn't make sense to me.)

I considered that the ABS control module is somehow damaged... but is it likely that control module problems would be confined to a single speed sensor? (And, again... that sensor mostly reports the correct wheel speeds... and it correctly changes the code if the sensor is unplugged... so it seems unlikely to me that the main guts of the ABS are involved?)

Is there something related to the ABS that can be reset, or relearned, or tweaked with VCDS?

Does anyone have any ideas for narrowing the problem down to the wiring, the bearing, the sensor, or some larger part of the ABS system?

At this point I will gladly entertain any and all suggestions.

Thanks!

Have you tried swapping the sensors left to right to see if the problem moves with them? I'm assuming left and right sensors are interchangeable?

Or perhaps running some "overlay" wiring to the right front sensor? It doesn't need to be routed elegantly for testing purposes.

Thanks for the reply. Understood about logs vs. print.

I will think about how I could best interchange the sensors. While I'm sure the actual electronics are identical, the housings are mirrored. There's an allen bolt that holds them in place, and using the left sensor on the right wouldn't allow that bolt to be tightened.

That said, the sensors fit in quite tightly, so I'm pretty sure they could hold in place with just the pressure fit, for a test drive.

I tried swapping the left and right sensors.

As mentioned, they're mirrored, not identical. I did my best to put them in the orientation they should have been. (There are two plastic ribs that face in, toward the center of the car body, when they're installed normally... so I used those as a reference.)

I couldn't use the allen bolts to secure them, as those holes don't line up when you use the wrong sensors. It's also possible that the sensors couldn't sit as flush to the knuckle as they'd have liked. However, they were both securely connected to their wire harnesses, and they were both essentially in position.

The result was 00285 "open circuit" codes on *both* sides, not just the right. (I cleared codes a few times while fiddling with sensor placement. A couple of times I got the "Implausible Signal" flavor of 00285 code from both sides... but when cleared, and re-scanned, they somehow morphed back into the "open circuit" codes for both sides. Mainly, I was getting "open circuit".)

These Open Circuit codes would always reappear immediately after I cleared them. (Which is different from my original Mechanical Failure code, which only comes back after driving the car a short distance.)

Eventually I put the sensors back in their proper spots and cleared the codes. I now am showing no codes. However, since nothing has been changed, I'm certain that once I drive a little, I will be back to my Mechanical Failure on the right side. (I'm tired, and the car is raised, so I won't test drive it again until tomorrow.)

These Open Circuit codes puzzle me. Implausible Signal makes sense, if it's not possible to get them seated right in their reversed positions, or if the sensor signals are somehow qualitatively different from one side to another... but I most consistently got Open Circuit -- even though they were both securely plugged in. This goes against my understanding of what Open Circuit means.

Maybe there's a qualitative difference in the left and right-side sensor signals (even though the sensors look identical)? Or some sort of coding that needs to happen, so the ABS system will accept them??

Do these results suggest anything to someone with more experience?

(Edit: I see that the codes in the log I posted below say "Electrical Fault in Circuit", not "Open Circuit", though I could swear I was also seeing "Open Circuit" in VCDS.)

With reluctance, I've ordered a proper Bosch abs sensor, and will update this thread when it arrives.

The sensors seem like the most fragile and temperamental link in the chain... when reversing the front sensors got me twin Electrical Fault codes, it reminded me what sort of weirdness can happen when a sensitive device is even a little out of spec.

It's very plausible that my original sensor was damaged when I did all the suspension work, and that my ebay replacement was junky enough to never stand a chance.

I should follow my own "Harbor Freight" rules when ordering ebay car parts... simple tools (or straightforward parts) are often worth a flier, but sensitive stuff that relies upon precison or internal quality... not so much.

I would installed factory sensor and log wheel speeds from all sensors. If wheel speed is measured correctly at all sensor and the signal is not dropping out. I would then check the wiring and all connections.After that I would then be looking at the abs module. I would repin the connector for ABS to see if the fault stays with a particular circuit or wheel speed sensor even though its taking the reading from another. If so this is a common issue with failing ABS units.

Sensor replaced with new Bosch sensor from reputable vendor. Same issue as before. ABS warnings after a couple seconds of driving. Front right wheel speed is correctly reported in Measuring Blocks most of the time, but briefly craters every couple of seconds.

For example, at 22mph, all four wheels will mostly report 22mph... but every second or two the front right will flash, say, 5mph for a split second.

Wiring near sensor looks good, visually, but I cannot tell if it's broken inside. I don't know how to tell whether the reported wheel speed dips are a result of bad wiring or a problem with the wheel bearing.

Sensor replaced with new Bosch sensor from reputable vendor. Same issue as before. ABS warnings after a couple seconds of driving. Front right wheel speed is correctly reported in Measuring Blocks most of the time, but briefly craters every couple of seconds.

For example, at 22mph, all four wheels will mostly report 22mph... but every second or two the front right will flash, say, 5mph for a split second.

Wiring near sensor looks good, visually, but I cannot tell if it's broken inside. I don't know how to tell whether the reported wheel speed dips are a result of bad wiring or a problem with the wheel bearing.

Have you unplugged the J104 module to do wiring check and also check possible contact corrosion?

Unplugged ABS controller (J104) and visually inspected. Connector pins and harness look perfect. No visible damage to wires near J104.

This was expected. If the wiring is at fault, it'd probably be in the right front wheel well, where I did all the suspension work.

It looks like pins 18 and 6 on J104 are the ones for G45 wheel speed sensor. I've read about people directly wiring speed sensors to ABS modules... but I don't see how I'd do that without totally cutting apart the wiring harness right at the J104. There are an awful lot of wires entering that thing, and probably not much slack to work with.

I've made an appointment with a garage, but it's a few weeks from now. So I plan to keep working at this in the meantime.

What now?

One thing I've been wondering...

My code is the Mechanical Failure - Intermittent flavor of Fault 00285. But there are also other flavors, like Electrical Fault in Circuit or Open/Short to Plus. Logically, I'd expect a wiring issue to throw one of *those* varieties of 00285.

Does Mechanical Failure really mean that I should be focusing my attention on mechanical stuff - like the sensor air gap, or a problem with the magnetic ring in the wheel bearing?

Put another way: how much should I trust the sub-types of error code (Mechanical Failure, Open Circuit, Short to Plus, etc...)?

Could be but normally you would have a damaged ring or something.

Hi precursor,
Do you have an oscilloscope? If you scope the signal at the wss connector you may see individual reluctor signals dropping out, proving it is the bearing. If the signal is good and consistent then run temporary wires (overlay) to the ABS module and test. If that clears the problem you know that you need to make a permanent solution.
Regards HMC

FOLLOW-UP / SOLVED

Thanks to all who posted suggestions.

I decided to take the car to a local VW shop with a stellar reputation. I had good, affordable results from these guys in the past, and they're specialists, and the place is easy walking distance from my house. My logic was: I'd already bashed my head against this problem for so long that I just wanted to get it resolved, learn from what they found, and move on to the next problem. There were enough potential causes (sensor, reluctor ring, wiring harness, ABS module) that I could envision myself running in circles if my guesses were wrong.

Well, the professionals didn't work out so well.

I think the problem was: they knew I'd been working on the car. This made them less motivated to solve anything, because they figured I had messed everything up... and because I wouldn't pay them to do stuff I thought I could handle. (The first part might have been true... but the second part was false... if they'd quoted something reasonable, I was ready to have them fix it.)

Anyway... they diagnosed it as bad wires near the sensor, and recommended a genuine Audi harness. Specifically, they pointed to some soldering I'd done on a connector, saying that was the problem. But they didn't seem interested in actually doing the work... they acted like it was agreed-upon that they were just going to diagnose. (I had never specified that... I figured there'd be a phone chat once they'd diagnosed it, and I'd play it by ear.) My policy is to never hire a contractor do a job they clearly don't want to do... because the results tend to be poor... so I just took it back.

But the diagnosis didn't feel right to me. Instead of ordering the $350 or so wiring harness, I cut the sensor wiring all the way back to the grommet in the wheel well, and rigged wires back to the sensor. No change whatsoever. It wasn't those wires. The pros had just glanced at it and condemned my wiring, instead of actually doing any troubleshooting.

Thinking about it more, I decided that the wheel sensor patterns I'd seen in VCDS - with the front right wheel speed dipping down every couple of seconds - just *had* to be the magnet/reluctor wheel in the wheel bearing. It made so much sense. So I ordered a magnetic-field-viewing film from amazon (there's one made specifically for automotive work, but it was backordered, so I ordered one that's basically marketed as a toy/educational item... it works great). I also ordered a new bearing... because somehow, I had become absolutely convinced that this was the problem. ;)

I took out the suspect bearing and put the film over the ring. Here's what it looked like:

FXuMEDv.jpg


It didn't look right to me... but then, I'd never looked at one of these before.

There was a lot of suspense when I the new bearing under the film. Fortunately, here's what that one looked like:

iJB7tvo.jpg


You can bet I was happy when I saw the difference. I knew the new bearing would solve my problem, even before I installed it.

I just installed it and did a test drive, and it works great, even with my crappy temporary wiring harness! Now I just need to go back and make the wiring a little more durable. Then I can concentrate on normal Audi problems again. Like my variety of slow fluid leaks.

I'm annoyed with the local shop. True, they only charged me $100 (which is nothing in car terms, and not worth fighting over). But they gave me an incorrect diagnosis that was much *worse* than nothing, and they presented it as fact, not just a guess (which it totally was). They caused me to chop up a mostly-good wiring harness, and lose some sleep.

I wouldn't have been surprised if this had happened at some random garage... but these guys have been doing this *forever* in the same location, and Volkswagen group is their specialty, and their reputation is just top-notch. That's why this caught me so off guard.

Anyway. Thanks to everyone who posted suggestions. They helped my thinking process quite a bit.

Glad you were able to get it resolved. This stellar reputation for this shop is based on what? Most places get a good reputation because of the personel that works there, once the personel changes the reputation does not. Not for nothing but I would never pay any place any sort of fee for diag if I wasn't willing to do the recommended repairs, however I swing a wrench for living so that's not a problem for me. To me it seems that they took the easy way out, pointed at something/anything that stood out just to get the diag fee this is just my opinion. Glad you were able to get it resolved and now you really know how stellar that place is. That being said no place is perfect, it comes down to the ambition to fix the vehicle correctly, most like load the parts cannon some try to scare people away with high prices. I've never done business this way and refuse to do business that way, then again my reputation is everything to me and to my customers.

I think it comes down to: they're a small shop with very limited stalls, they have tons of business right now, and there's tremendous incentive to cherry-pick the jobs that will pay best.

I had a difficult electrical problem many years ago that they solved cheaply and effectively, and which I'd expect many shops would have fired expensive parts at. So, I have seen them at their best.

But you're right, I'm sure there has been turnover since then. And even if some of the same guys remain, they can't all be zingers. ;)

I realize that any job involving customer service is a fine line, and no matter what you do, you'll be criticized. But I wish that in this case, if they didn't want the job, they'd have just said: we're too busy, we don't want take this on right now.

But maybe that's expecting too much.

Can you post a pic of the item that you replaced, that produced those patterns? What I'm visualizing is more a reluctor ring than a bearing, although I suppose the two might be integral in this application?

These cars have the magnetic ring embedded into the back of the bearing. This pic is of the bearing/hub assembly. The black rubberized ring facing upwards hides the magnets, so you can't tell anything just by looking at it. (Well... unless there's massive damage and the rubber is all chewed up.)

I didn't realize all of this when I replaced the first bearing. I distinctly remember dropping the bearing/hub assembly onto the floor before I installed it. At the time I didn't think it mattered. It's possible the impact smashed the magnets out of place. Or it's possible that the odd pattern just came from a manufacturing defect. I don't have enough experience to know.

While it's in theory possible to replace just the magnet ring, I couldn't find any products, kits, or instructions for doing that. It seems like everyone just replaces the bearings.

Ring is part of the bearing, I would not be dicking around trying to change just the ring then finding out after having it back together that its still not right. Do it right and do it once and move on. This is my motto, words to live by. Also note I have seen some guys not paying attention changing the bearing on another audi product that had a similar setup with the magnetic ring however bearing was press fit not a bolt in, and had pressed the bearing in backwards. Magnetic ring only on one side. Needless to say that guy was not happy that he fucked up.:D


Judging by the shape the original bearing made with that magnetic film I suspect age /corrosion and iron build up caused the pattern you see.
