Hi Dana,

Yes I have power to fuse # S15. Also, yes there this power to fuses (S2, S13, S14, S15, S16).

Fuses ( S7, S8, S9 and S10 ) are NOT RECEIVING POWER. Relay #167 also called J271 in the A3 position has a voltage of approx 12.32 volts. I get the same reading from my multimeter for the A1 J670 relay (just fyi). Note: I have also replaced both relays #53 & #167.

Thanks Dave

Thanks. That adds clarity.

In regards to the fuses in E - box , air plenum, left:
  • S11, S12, S17 and S18 all receive power from splice D121. That splice is powered by terminal 87 of J670 [A1]
  • S7, S8, S9 and S10 all receive power from splice D123. That splice is powered by terminal 87 of J271 [A3]
Both of those terminal 87's are the (high amp) switched side of the relay so I suspect neither are operating. We need to tread very lightly with copyright repair info but 2 temp links that may be of assistance are:
You might want to jump the 30 and 87 legs with the relays removed to verify that all components receive power however doing so won't get you closer to the reason they aren't working properly.

The next time they are removed I would verify both 30 -and- 86 terminals are powered. If they are then you might need to check the 85 terminal ground control via the ECM (J220).

Also, keep an eye on the KESSY for fault codes (as Jack mentioned) because it directly controls power to many things.

In regards to Fuses "SC" in right side instrument panel fuse box, up to July 2006:
My diagram shows 2 blanks in the bottom-most positions you have highlighted. Please make sure those aren't just blanks with spare (extra) fuses.

Hi Dana (Thanks again for your help)

I think we are getting closer to the problem. All of the fuses that you listed DO NOT have power currently.

Here is my plan of attack for tonight.

1) Do as you say, "jump the 30 and 87 legs with the relays removed to verify that all components receive power". Once I bridge termial 30-87 (with the relay removed) the corresponding fuses in the plenum E-Box should be energized. If they ARE successfully energized then bad relays. If the are NOT energized I am thinking bad ground or broken wire, correct?

2) Remove the relays from J670 & j271 and confirm that 30 and 86 terminals are powered. If yes they are powered then check terminal 85 (on both relays) to confirm a good ground via the ECM J220.

Question: Q1;Where is ECM j220 (I can't find it anywhere in my manual)?
Q2; I am jumping terminals 30-87 and checking that terminals 30 & 86 have power, correct?

Thanks again, Dave

Hi Dana,

Alright, I did as you said last night and I removed the relays from J670 (#53) and J271 (#167) and I can confirm that both of the terminals 30 - and - 86 are both powered.

Also, with the J271 (#167) relay removed if I manually bridge the 30 - and 87 - legs all of the fuses on the plenum box that were previously dead become energized (fuses #7-12 & #17-18 that I marked in red previously).

Question: Would this lead you to think that the J271 (#167) relay is faulty? I have already replaced this relay, but I am happy to try again this evening. If this is not the case and the relay is indeed good...what should I be checking next?

You previously said if the terminal 30 - and - 86 are powered, which YES they are, that , "...then you might need to check the 85 terminal ground control via the ECM (J220)."

Question: How do I check the ground for Terminal 85 via the ECM J220?

Good morning and thanks again for your help. It seems that we are making progress toward the ultimate cause of the problems.

Correct, the fuses should be powered when you bypass/jump the relays. The engine should also start/run and I would re-scan it but I'd make sure to remove any jumpers shortly after the testing. Don't leave it powered up and walk away to get a coffee.

Keep in mind, if jumping relays results in power to the fuses and components that doesn't necessarily mean the new relays are at fault. That is only going to verify the terminal 30 source is OK, terminal 87 wiring to and through the fuses is OK and the components themselves are likely OK as well. You may have a ECM relay ground control issue, wiring problem, or (least likely) missing 86 terminal power to operate the relays.

2) Remove the relays from J670 & j271 and confirm that 30 and 86 terminals are powered. If yes they are powered then check terminal 85 (on both relays) to confirm a good ground via the ECM J220.
Exactly.

Question: Q1;Where is ECM j220 (I can't find it anywhere in my manual)?
Q2; I am jumping terminals 30-87 and checking that terminals 30 & 86 have power, correct?
1) Try the Pass side E-Box, perhaps under the ABS based on my fuzzy recollection.
2) Yes, to both.

As a general rule you only want to jump the high amp (switched side) of a relay which is 30 & 87 in this case. Never jump power across the low amp side to the controller ground (term 85) because it could fry the module if the resistance (load) of the relay wasn't present. When dealing with a basic 4 pin relay system the switched side almost always use larger terminals and the low side uses smaller ones but I never ASSume. Always use the diagram, question the accuracy of that diagram, verify the wire gauge/female terminal size matches and then proceed. :thumbs:

Our replies overlapped but see if it runs, and if so, make sure there are only 2 DTCs for the bypassed relays that reoccur.

You previously said if the terminal 30 - and - 86 are powered, which YES they are, that , "...then you might need to check the 85 terminal ground control via the ECM (J220)."

Question: How do I check the ground for Terminal 85 via the ECM J220?
Since those grounds originate at T121a/23 before hitting a splice (D120) point I would check for ECM ground directly at the ECM. The module needs to be plugged in and you would slip a back-probe pin (bent non-coated safety pin, tiny paperclip) along the side of the wire so it touches the terminal. Don't puncture into the wire insulation if it can be avoided. I would use a DVOM with the red lead on B power and black lead on that back-probe pin.

Correct, the fuses should be powered when you bypass/jump the relays (YES, with relay J271 (#167) bridged the fuses do indeed become energized) . The engine should also start/run (tried cranking it but would not start. I will auto scan tonight with the terminals bridged on J271) and I would re-scan it but I'd make sure to remove any jumpers shortly after the testing. Don't leave it powered up and walk away to get a coffee (OK).

Keep in mind, if jumping relays results in power to the fuses and components that doesn't necessarily mean the new relays are at fault. That is only going to verify the terminal 30 source is OK, terminal 87 wiring to and through the fuses is OK and the components themselves are likely OK as well. You may have a ECM relay ground control issue (a ground issue is what I am leaning towards. Is this the J220 ground that you mention below in the Passenger E-Box under the ABS???), wiring problem, or (least likely) missing 86 terminal power (Terminal 86 has power on both J271 & J670) to operate the relays.

Exactly. (I will do some YouTube research and check the terminal 85 ground with my multi-meter regarding the J271 female relay receptacle).

1) Try the Pass side E-Box, perhaps under the ABS based on my fuzzy recollection (First I will check the J271 relay receptacle for a good ground on terminal 85. If bad ground then check the Passenger side E-box ground connection. If good ground for J271 on terminal 85 report back and move on. CORRECT???).
2) Yes, to both.

Here is what I am going to do today…

1) Purchase 1 new #167 relay for J271 and see if fuses #7-12 and 17-18 become energized without bridging the connection manually.
2) Check J271 female relay receptacle terminal 85 with mulit-meter for good ground connection. If I find that Yes there is a good ground on 85 report back. If NO GOOD GROUND is found on for J271 on terminal 85 check J220 Module Ground behind Passenger E-box.
3) With all of the plenum ebox fuses energized (either through bridging J271 terminals 87 – and – 30, replacing the possibly faulty relay #167 or by identifying a grounding issue) attempt to start the Treg & provide a fresh auto Scan.

Is there anything that I am missing or is my plan of attack good???

The plan of attack sounds good. We can advise further based on those results.

2004 TOUAREG V6 3.2L YES CRANKS BUT NO START

Hi

Here is the latest scan. Sorry, I can't figure out how to post scans to an old thread (only when I start a new one like now).

I am still working on all of the things that Dana and I discussed earlier today, but I wanted to post the scan.

I bridged the terminals 30 - and 87 - on the relays in J670 and J271 (#53 & #167).

NEW SCAN...

Hi

Here is the latest scan. Sorry, I can't figure out how to post scans to an old thread (only when I start a new one like now).

I am still working on all of the things that Dana and I discussed earlier today, but I wanted to post the scan.

I bridged the terminals 30 - and 87 - on the relays in J670 and J271 (#53 & #167).

NEW SCAN...

The car cranks but doesn't start? hmm. Usually that would be an issue with either the car not producing the spark or the fuel pump is not working right or engine issues

Possible diagnosis steps:

1) Check your battery with a multimeter, ensure it's health is good and it's holding charge
2) Check whether your fuel pump is good, usually you can hear the fuel pump run when you start the car in accessory mode (not engine on)
3) Check fuel delivery lines to engine?
4) Get the compression of the engine tested using a compression tester (independent mechanic or friend)
5) Check spark plugs using a multimeter (check the resistance)

Edit: Ah I just saw your old thread, so the above info is redundant

Hi Dave,
Just to avoid any confusion, the ECU will switch the earth (ground), so you will need the ignition on when you test terminal 85 if goes to earth correctly.

Here is the latest scan. Sorry, I can't figure out how to post scans to an old thread (only when I start a new one like now).

Hi guys,

Thanks, HMC is correct. I assumed it would be tested key on with ECM connected but it must be if that wasn't clear. Otherwise the controller can't flip the control wire to ground.

gokarty, Those aren't completely redundant. Sometimes a new evaluation from fresh eyes is exactly what someone needs! Checking for spark, fuel, compression, etc. are great ideas since it still doesn't start with jumped power.

In addition to the above contributions I don't like the fact that these aren't intermittent:

17522 - Oxygen (Lambda) Sensor; B1 S2
P1114 - 002 - Internal Resistance too High
17548 - Oxygen (Lambda) Sensor; B2 S2
P1140 - 002 - Internal Resistance too High

It is extremely unlikely that a faulty O2 sensor would directly result in a no-start or voltage drop to more important components (Injectors, Coils, etc) but I would unplug that sensor entirely. Doing so will rule out the possibility that it is causing an electrical malfunction and you can deal with it after the vehicle runs again.

Hi HWC & Dana,

I didn't make it as far as I had thought last night.

Here is what I did on the 3 tasks:

!) I did replace the #167 relay. No help. Still all the same problems.

2) Skipped this step on verifying the ground on terminal 85. I believe there must be some major grounding problem to give off all of the fault to ground errors and intermitent signals that I am experiencing. Finding the grounding issue I believe needs to be my majore focus because of the reasons listed below in #3.

3) I did indeed bridge the terminals 30 - and 87 - for both of the #53 & #167 relays and as expected this did light energize all of the fuses in the hood plenum e-box. Even with the terminals bridged it would just crank and NO start. Then I did the scan and you can see all of the grounding faults/errors.

Even with the termils bridged the fuel pumps will not prime. They have both been replaced and all of the other fuel filter components have been repalced as well. They both power up with direct charge or even if I use a tester in the 404 relay slot they will charge.

Howerver, even with the termianl bridged in the plenum e-box the fuel pumps will not prime when I open the drivers door. Could the grounding issue be keeping the fuel pumps from priming and the car from starting even with the terminals bridged?

Thanks. Its frusterating but I will get this done - a large part because of all of your assistance - Thanks again.

One other quick note:

I went home on my lunch break and with both relays #53 & 167 from the plenum ebox removed and the terminals 30 - and -87 bridged (key in the on position) I noticed that I can hear mild audible humm/high pitched wine for approx 10-15 sec. It comes from the back of the engine bay on the passenger side - not the where the main ECU is located buy by the back of the engine.

Just thought this might be something of substance.

The humm/whine goes away after the 10-15 sec and also if I don't have the terminals bridged manually.

In reply to post #31, I would expect all of those Intermittent 01-Engine DTCs for the engine components to clear (as long as the relays are jumped and power is present at the time). It couldn't hurt to make sure they do at some point.

You could troubleshoot the lack of fuel pump relay activation in the same way to see if the ECM isn't grounding those either. If this is a ground control problem it could be the ECM but verifying ALL powers and grounds to it are OK would be necessary before condemning the control unit.

Perhaps more importantly, I don't know how I missed it but back in post #5 you mentioned water in the E-Box and that's where the relays in question live. I wouldn't doubt if many of the splice points in the diagram are in that general area as well. Definitely make sure to load test and inspect that area very carefully!

In reply to 35/36, the audible humm/high pitched wine might be a normal throttle body noise but I would check to see what component it is coming from. If you believe it to be the TB then I don't think I'd get excited. They make noises like this 2:26 mark with the key on and while calibrating: https://www.youtube.com/watch?v=2zrmhDw_v7Y

Over the weekend I am going to be testing the driver's side plenum ebox for good grounds and following them to all splice points in the hopes of finding my problem.

I paid for and downloaded the entire erWin wiring diagram, but I do not see anywhere that lists all of the grounding points and the splices/connections.

Does anyone have a good list or diagram of the grounding for the 2004 V6 3.2L Touareg???

If you ended up downloading a massive single PDF (containing all vehicle diagrams) search it for diagram number "801 / 1" -or- "Ground Connections". I can't post the entire thing, due to copyright violations, but this small snip in a temp link may add engine bay clarity.

Keep in mind, those are only the locations where grounds bolt to chassis ground. The locations of splices (including ground splices) within the harness may not be documented. I wasn't able to locate any splice point information.

Alright,

Last night I went out and rented an "Evertough Relay and circuit tester" tool from my local Oreilly Auto Parts.

What I found was that several of the Ground and/or hot receptacles (where the relays plug in to) have bad connections and readings. What I mean is that if I plug in the test I will either get a good signal or not and that when I adjust (wiggle) slightly the prongs of the tester in the electrical female whole I can get a different reading.

Meaning: either from the presence of water there is a weak connection (corrosion) or the metal female recepticle is loose.

FIX: I am going to open the open up the Driver's Plenum Ebox and clean/Re-do the connections where the relays plug in to.

Question: Does anyone know of a kit or tools to remove the pins from the relay receptacles? I am thinking there may be a set of keys for the different size electrical pins and maybe a crimping tool to get the female pins back to their correct shape/snugness.

Thanks again for the help. I truly think that this is where all of the issue lie because of the presence of water in this ebox previously.

Dave!!!
