Got a 2004 R32 3.2L BJS motor

Please bear with the story because I want you to understand the history of the car. (I know I am long winded also.)

A few years back did ton work on the car almost 4 grand for customer. Car always only had exhaust flap code and customer said check engine light was always on. After all the engine work, crack pipe, w/p control arm ext. I wanted the check engine light off for the customer. Above the heat shield at rear muffler is the solenoid and bracket and the noid is totally destroyed from age and weather. Changed the noid. Finish car gave back no Mil and all readiness set.

Month later Mil is on SAI incorrect flow. Told customer may have to go into service position again to see what is wrong. Customer didn’t want to spend any more money at the time which I can understand. Plus here there is no emissions here to worry about so as long as it is just SAI I let it go. But I was disappointed! I wanted the Mil off car is that nice!

Car comes in long time later for an oil change and I go thru the SAI system. Pump runs strong, Noid for Kombi valve works well with vac to Kombi good, Kombi opens and with pump running I can feel the pressure in exhaust so exhaust ports are open. But will not set SAI readiness. Scratching my head I give car back after the oil change.

Car comes in last month for oil change a year or more later and I have no SAI code? But the car now has a B1S1 no activity code. I tell the customer this we have to fix it’s an important one and B1S1 is needed for ECU to test the SAI readiness so maybe cause of both. Car has a 100k on it so I just ordered a new O2 B1S1 on the passenger side bank with #1 cyl. Cleared code and test drove the car both S1 B1 & B2 sensors started working quickly. About 5 miles into test drive on highway 001 field 3 for B1S1 goes to 0% and stays there? Won’t start working again dead at 0% and code sets without Mil on. So I cleared codes and returned to 001 field 3 and it’s working like a charm. Drive a few more miles and B1S1 goes dead at 0% again. This time I cycle the key instead of clearing codes and 001 field 3 is back to working fine. A few miles later 001 field 3 at 0% and Mil comes on because I didn’t clear and it is the second trip. But if I cycle key or clear codes B1S1 works again?

Measuring block 033 shows working field 1 B1S1 % working until it goes fixed at 0%. Field 2 show above and below 1.5V when Field 1 goes dead at 0%. Field 2 voltage goes a little high at idle 1.7v to 1.8v drive it and voltage is back to above and below 1.5 volts while field 1 is dead at 0%. Does that mean B1S1 is working by voltage just ECU is no longer in control of fuel trims?

Feels to me as if the ECU is just not reading the B1S1 right and I believe O2 is working fine I just can’t see it work in 001 field 3. If it was the O2 why does it work so well after a key cycle or clear codes command and doing the exact same thing as original O2?

If it was any other car I would have swapped out ECU already but a spare R32 ECU for testing is not easy to come by and cost a lot based on a guess!!!!
I am not NostraJackAss with one sitting on a shelf LOL. I am Just a poor coal cracker from N.E. PA.

My questions:

Who agrees bad ECU & who doesn’t? Locks up reading B1S1 and before that wouldn’t set readiness for SAI and I saw no reason why. Now can’t pass O2 to run SAI readiness.

If you agree bad ECU do you think update firmware or re-flash before replacement? If so I will send it to NostraJackAss.
Can’t send to my local dealer last time they bricked the ECU, replaced with an aftermarket and lied about it. They gave me a new OE one and I had to send to Jack for the right update.

Are there any updates or TSB’s for this problem?

I do not know how to back probe a wideband O2? Older style O2 you could back probe the signal wire with a meter to see if it was actually working or not. I would like to back probe this one when ECU locks at 0% to see if O2 cross counts or is dead as VCDS shows. If O2 works and VCDS shows 0% that would tell me bad ECU. Don’t know how or if you can back probe a wideband O2 never had too always read it on a scanner.

The O2 ordered was 022 906 262 BB from Northside Imports.
What I got was a Bosch 17359 VW # 1K0 998 262 J Bosch 0 258 077 359 all written on box as far as I can tell it’s the most updated one and correct for the right side upstream.

Thanks for the help!

Hey "SLMC"

I have a question............
Are the OXS sensors factory genuine?

What is the condition of the MAF?

Are there any vacuum leaks at all in piping and especially from AUX vacuum pump on sub frame by rack?

Have you attempted a balance wire to check for bank observation to authenticate the OXS aging control?

Have you defaulted and recoded ECU?........ please change tester # and WSC to verify!

Hey Jack your the only one who love's me.:(
Anybody else have any ideas? Dana, Jeff, Jetta97 anybody?

O2 was a real Bosch but not from dealer. Original was original! but both do the same thing?

The O2 ordered was 022 906 262 BB from Northside Imports.
What I got was a Bosch 17359 VW # 1K0 998 262 J Bosch 0 258 077 359 all written on box as far as I can tell it’s the most updated one and correct for the right side upstream.
Is it the right one?

"What is the condition of the MAF?" Good as far as I can tell anything special you want me to do?


"Are there any vacuum leaks at all in piping and especially from AUX vacuum pump on sub frame by rack?"
All vac. hoses are good but I can't check the Aux pump yet only have one lift and I got a big Job on there at the moment.
As soon as lift is open I'll get a look in a day or two. Car will be here no rush customer is cool.

"Have you attempted a balance wire to check for bank observation to authenticate the OXS aging control?"
There you go again great Yoda... I keep telling you I have no factory VAG training at all! I have to learn everything the hard way! Mostly from my mistakes! LOL
I got no idea what that means? Sorry! I am just a stupid Polish Coal Cracker! I am trying but I'll never be a Jedi :cry:
Maybe I should come intern for you for a few months. Because being stupid really pisses me off! But I can't help it I'm Polish.
Could you please explain that in plain Polish?
I can't follow half of what you say in posts you loose me so quickly. And I am sure half these back yard guy's are totally lost.
I am surprised I got the code tags right and Uwe didn't have to edit them.

"Have you defaulted and recoded ECU?........ please change tester # and WSC to verify!"
Oh boy I feel the Polish in me coming out... But amazingly I think I did it.
Login was accepted but when I tried to re-code to an auto it wouldn't except it. I figure there is no auto R32 so it couldn't.
So I re-coded to the same code 0000132 and changed the last digit of WSC to a "3" to verify.
Hope your proud of me? I sure am 2 yrs ago I never would have been able to do that.
But I didn't understand "please change tester #" Is that the code string 0000132 ? Whats a tester #?

Well test drove again after re-coding and changing the WSC and the exact same thing happened with B1S1 at almost the exact same turn in the road at 4 to 5 miles.
Almost feel like there is some electromagnetic force in road I drive. It's like clock work when the fuel trim goes dead.

Are there any updates for this ECU?

Thanks!

Is it the right one?
Most likely a clone based on what you are describing and have verified this before, if you need an ECU I have brand new ones.
ME7.1.1 has a cross check function that shuts down the OXS sensor observation, if not within a test parameter to force you to genuine dealer parts.
Unfortunately it seems Northside seems to sell these in non Bosch clear bags wrapped in some foam.....which makes them questionable.

"Have you attempted a balance wire to check for bank observation to authenticate the OXS aging control?"
There you go again great Yoda... I keep telling you I have no factory VAG training at all! I have to learn everything the hard way! Mostly from my mistakes! LOL
I got no idea what that means? Sorry! I am just a stupid Polish Coal Cracker! I am trying but I'll never be a Jedi :cry:
It is not a factory test and is one I created..........from time to time I deploy it.
It's when you take the data signals from the other bank and feed to simulate the bank in question, just to check the ecu is responding accordingly.
Other than the heater as an exception!

"Have you defaulted and recoded ECU?........ please change tester # and WSC to verify!"
Oh boy I feel the Polish in me coming out... But amazingly I think I did it.

Hope your proud of me? I sure am 2 yrs ago I never would have been able to do that.
But I didn't understand "please change tester #" Is that the code string 0000132 ? Whats a tester #?
I am proud to call you my friend SLMC & you did good...........and yes that is correct but the tester # can be specified in VCDS config screen.
R32 in USA 022-906-032EG is Stick only.....


Well test drove again after re-coding and changing the WSC and the exact same thing happened with B1S1 at almost the exact same turn in the road at 4 to 5 miles.
Almost feel like there is some electromagnetic force in road I drive. It's like clock work when the fuel trim goes dead.

Are there any updates for this ECU?

No, however, if you determine you need and ECU again I have new and reman + access to a R32 for testing special issues.

Let me know and I am no one special nor a Jedi ........just a Jack Ass!

O2 was a real Bosch but not from dealer. Original was original! but both do the same thing?

The O2 ordered was 022 906 262 BB from Northside Imports.
What I got was a Bosch 17359 VW # 1K0 998 262 J Bosch 0 258 077 359 all written on box as far as I can tell it’s the most updated one and correct for the right side upstream.
I can bet this is your problem!!!!!
Did you hear what happen lately with them????
Also this company has worst customer service ever, and I do not know single person that did not have problem with them.

If you want good quality part buy it form JACK , he will not ever sell you Crap.

Okay I'll change the O2 again.

Nothing worse then asking for advise then not following it!

I do agree about customer service with Northside but that was depending on the sales person you got.

"Did you hear what happen lately with them????" No I did not please tell? If you don't want to tell me on a open forum P.M. me. Thanks!

I have gotten bad parts before that's for sure. And I have gotten things in bags before instead of boxes but I figured it was cost savings when buying bulk.

This O2 however was in what looks like a factory Bosch box to me!

I can't tell you how many time I have gotten things not expecting OE and they came in official dealer boxes! 2.5 liter valve cover for one are always OE!

I also know china spends more time cloning boxes then parts!

It will be a day or so got to get my lift open again.

Jack you were thinking about me after last post and even e-mailed a customer about this. Your the best I feel the love. Thanks!

Thanks Again!
Good Luck

... stories that start off like this tend to end poorly. Pretty much a statement I issue daily is If it has an electrical connector on it, get it from the dealer. Then I ramble on about failed production runs and midnight production runs... something gets that part cheaper.

What no balance wire gravy first?
What it walks backwards?

All parts are subject to revision or quality control flaws even the dealer.

That is why we have supersessions and TSB's or even actions or campaigns.

Don't hold the OEM too high on a pedestal Jef because if the numbers can be crunched, you can bet your ass they will try.

It is "our job" to look at stuff and know "how" it works or "figure out how it works" &........ to detect such flaws!
:D

I said explain in basic Polish.

"It is not a factory test and is one I created..........from time to time I deploy it.
It's when you take the data signals from the other bank and feed to simulate the bank in question, just to check the ecu is responding accordingly.
Other than the heater as an exception!"

"What no balance wire gravy first?"

I also asked if there was a way to back probe the O2. Because I got no idea what type a signal wide band O2's send.

I understand taking the signal wire from B2S1 and using it to feed B1S1.

Do I use B2S1 signal wire tapped into both O2's?
Do I Swap both B1S1 & B2S1 signal wires with each other?

Then comes the big question. What wire is the signal wire?
5 out of the 6 wires go to the ECU.
I figure 1 is power to the heater and one is a ground but I can't figure out which one is the signal wire I need.

I know I am a dumb Polish Coal cracker but I'm no Yoda!

Gravy my ASS! Swapping O2 that's gravy. Just paying for another one sucks.

This is were you kill me Jack! Not many people could figure out what wire is the signal wire from a diagram. But to you it's a piece of cake that's why your Yoda and I am not.

Plus I'd hate to cross something and do damage.

Good Luck

OK OK.....SLMC

Even simpler.....

In the case of V6 multi bank the forward or rear, OXS just grind the tit on the plugs and swap them to see if fault moves or wide band you can balance them pin to pin except the OXS heater circuits.

There are great back probes made from soldering safety pins onto alligator clips to do this. Oh and FYI the plug block for the forward OXS is unique and if from the wrong OXS sensor from some asshole installation of kits will be a nightmare.

They got busted by FBI, how good company it is!!!!!!!!!!!


Also read here about them products:
https://www.reddit.com/r/Justrolled...ke_timing_chain_thanks_northside_imports_inc/

And here is the answer form sells person when I ask why one part went up on price in 4 moths like $40 more:
"Save your breathe for someone that actually gives a shit, Marin.
You have been a pain in the ass from day one…just go away and save all of your cry baby shit for someone that has time for it."


Now you tell me this is good company????


How many times past 6 months people ask UWE why VCDS HEX-NET is more money now, and did he answer like that sales person above???
No he did not , UWE actually took time for every single user and explain very nice way all things about VCDS , that is the customer service we need and that is the Company you can trust forever.

I don't know Marin............ gas changes on a daily and sometimes twice ....."markets" trade on what prices people are willing to pay & based on demand.

That's why freedom of choice and price matter, as does quality.

And the eastern EU isn't what it was before ~1990. In fact, much of the eastern EU is less "socialized" now than the rest of the EU.

Okay Guy's and Gal's (To be politically correct even though Dana hasn't commented) got the OE O2 from the dealer.
Same part # as the Bosch from Northside. Updated to 1K0 998 262 J
Northside was a Bosch box and came with separate bag of wire ties and plastic's.
OE came in a plain white box also had the same separate bag of wire ties with the exact amount of plastic's.
Funny thing is the plain white box from the dealer looks like a clone. Northside's looks good in a Bosch original box.

But no good on the problem! Like clock work between 4 & 5 miles (on the same part of the road) B1S1 goes dead at 0% and will not work again.
Group 033 shows B1S1 0% and voltage still working above and below 1.5 volts. B2S1 works perfectly % and volts.
Cycle key or clear codes B1S1 is back up and running.

Load tested all B1S1 wires and all test good under a load. I also don't think wiring because it's like clock work setting the code between 4 &5 miles.
If it was wiring it wouldn't be like clock work every time.


I want to go back to my first post where I was explaining the history of the car.
For over a year this car had a SAI code that made no sense!
Kombi held vac. and was open. Manually apply vac. and run the pump you can feel the good air flow in the exhaust with engine off.
Noid worked and supplied vac. to kombi even held Vac in the tank with engine off. Couldn't figure out why? Everything worked but code would return.
Now however I can't pass O2 readiness to try and do SAI readiness.

My reason for bring this up is the O2 code sets like clock work! Could this be at the same time the ECU wants to run SAI test at 4 to 5 miles into a trip? And cause the O2 to go dead.
I was thinking the bad O2 was why SAI didn't pass once I got a O2 code.

Now I am thinking the ECU has a SAI problem and has for over a year and it has gotten worse. Now if and when the ECU runs the SAI test B1S1 goes dead for some reason?
God my brain hurts!
What is the best way to prevent SAI from running it's readiness test.
Disconnect the noid to kombi valve should set a code to prevent the test right?
I'd actually like delete SAI just to test this theory out but I KNOW YOU'S WILL NOT HELP DO THAT! LOL



So Jetta97 you would of lost your bet!
I can bet this is your problem!!!!!

I tell people the same thing when they try to hand me their own eBay parts. But I have not had that many bad original Bosch parts. But it does happen.

Thanks for the help!
Good Luck

Come on Yoda use the force!!!!!

Changed right side before cat O2 on the exhaust for #1 cyl.
Unless ECU is miss reporting O2 sensors? Which I do believe some did miss report cyl. miss fires years ago.

If some one has ever heard of miss reporting O2 sensors I'd love to hear about it!

Good Luck
