Help! Reconnected battery with ACC on. Now ECU won't communicate with cluster

[imabigdipper]

Basic info
2003 B6 A4
2.7t swapped with an ME 7.1.1 ECU out of an allroad. Immo deleted. 01E swap

What happened?
Needed to take the steering wheel off to adjust it. Key was in ACC position so I could disable the wheel lock to turn the wheel freely, and battery was disconnected so i didn't trip airbag codes.
Finished the job, and accidentally left the key in ACC position when I reconnected the battery.

Symptoms
With key turned to ACC, I get no CEL or EPC light. Cluster prompts "press clutch pedal to start engine", when previously it never showed this. Cluster backlight does not turn on when I turn on headlights, but the needles stay illuminated. Cluster shows correct mileage and fuel gauge works correctly.

Car cranks and starts/revs/drives perfectly fine. This confuses me, since from what ive read, usually a lack of CEL/EPC means ECU will not get power and will not start the car. However, car does indeed start. Speedo and tach stay at 0, and the cluster yells at me that there is no oil (there is indeed oil).

I am able to access both the ECU and Cluster through VCDS and read/clear codes as normal. Cluster has an implausible signal fault. So I suspect there is an issue communicating between the two.

Here is a quick video I made showing symptoms and explaining them.




Conclusion
So, it seems like the cluster & ECU independently work, and can communicate with the OBD port, but they cannot communicate with each other. I assume fuses/relays are ok since ECU is obviously getting power and able to start the car, but I have not checked yet. This leads me to believe the issue is some kind of short in the cluster/ecu or the wiring between the two.

Truth be told, I'm not familiar enough with the communication system in this car to begin diagnosing this issue. I know B6s use a combination of K-line and CANBUS, but thats about it.

Scan shows some faults for Yaw sensor and radio, both are unplugged, so those are unrelated.

I would appreciate some help/guidance from you guys. Admittedly a bit discouraged since this is a stupid mistake on my part.

Did the cluster harness plugs get touched when you took your wheel off? There are two of them, and I wonder if one got bumped and partially dislodged so that a pin lost its connection? In other words, perhaps it wasn't the fact that the key was in ACC, but instead something else you did while you were working. I just find it difficult to believe that having the key in ACC would do that. I find it less difficult to believe that an old plug could come undone.

Try reseating the cluster harness plugs. At least it's an easy place to start.

[imabigdipper]

I didn't touch the cluster at all, only took the wheel off to recenter it, I find it very unlikely that a connector came loose, but i will check tomorrow afternoon.

I'm with you, I'm also a bit confused on how just having ACC caused this. Maybe it has something to do with the swap wiring?

I think I'll start with clearing all DTCs again and going for a quick drive, seeing what pops up and then go from there.

[EuroxS4]

Clear all faults and see what comes back. I would also verify coding is correct in both modules. NO MIL indicates issue with the ECM.

[krazeedrivr]

"Depress clutch pedal to start" is correct if you swapped to a manual. Did you build your own wiring harness, buy a premade one, or buy the swap harness converter board?

https://www.27swap.com/2-7t-swap-board

[shurur9]

As EuroxS4 said, clear the codes first and see what remains.

The eçm needs to see the system come up in the proper sequence or it will get confused and give out confusing info.

It is a finite state machine (FSM) and having the acc on then the battery hooked up is a state outside the finite states that it understands and can go off into the weeds..

Maybe something got taken out with the açc on, but I doubt it is as bad as you think.

Swap was done by a previous owner, nefkntym on audizine. He did the wiring harness himself. Could be part of the reason this is happening.

In theory, yes, that prompt should be correct, but it never appeared before this issue, and the car has always been able to start with the clutch engaged. I'm not even 100% sure the clutch switch is wired up, i think it was bypassed somehow.

[krazeedrivr]

Have you tried just removing the steering wheel again and stepping through what you did to check for issues? If you haven't checked the fuse block for blown fuses yet, that would be my next point before undoing the wheel. Have you checked with nefkntym to see if he has ever experienced this issue? With a custom wiring harness (and disabled systems and switches) its likely to be a nightmare to diagnose without firsthand knowledge and he may have experience with this. I would try to get confirmation from him what all he did to make the system work like disabled clutch switches, etc. If you can't reach him, you may want to acquaint yourself intimately with the swap guide, especially in the wiring section. You may need to investigate how he accomplished it to resolve the issue on your own. I personally bought the wiring harness swap board so I didn't have to deal with wiring contingencies on my 2.7 swap, but it was not cheap. If it was me and I wanted this thing to be maintainable long term instead of investigating custom wiring until the end of time, I'd buy the swap board, another wiring harness, and replace the bypassed wiring and switches back to stock, BUT THATS JUST ME. I've never seen my 6MTQ not show "depress clutch" when turning it on, so I kinda feel like you had a masked issue before you pulled the battery. The key in the ignition may have had something to do with it but only because of custom wiring. Key in the ignition while reconnecting the battery should not damage anything in a normal car. This car doesn't have an aftermarket stereo/amps in it does it? It kinda sounds to me like there was a power surge that fried something, and my only guess is a wiring fudge.

One final thought, but you may consider bench testing your cluster. I have no experience with this, but you might start with this thread:

Every manual vehicle will give the press clutch to start message if you turn the ignition switch to the start position without the clutch pedal down, if the clutch switch is not bypassed. It's a reminder not a issue.

[krazeedrivr]

We agree. If I wasn't clear due to interwebz communications, because he wasn't seeing the message before pulling the battery, but now is, that could be a sign of a masked issue that caused all these problems, including for the message not showing up.

[Larhal]

Every manual vehicle will give the press clutch to start message if you turn the ignition switch to the start position without the clutch pedal down, if the clutch switch is not bypassed. It's a reminder not a issue.

I beg to differ, My 2002 with a 5MT dosent give the message. My tune has nothing to do with the Clutch message as I never had the message since I picked it up new from the dealer.

My European 02 5MT begs to differ as well.

[Cybersombosis]

I believe it has to do with country code. When I bought my 2001 back in 2009, an enthusiast with VCDS asked me if I wanted the seatbelt warning and press clutch message to go away and I said yes so he switched the country code to rest of the world or something like that and that got rid of them. Unfortunately it won’t work for the US as the rest of the world uses KM and not miles.

Could possibly be but my A4 reads in Miles here in the UK and it was originally purchased in Ireland..

[imabigdipper]

Hi all, thanks for the suggestions, was super busy yesterday and had no time to diagnose. Will get on that today, clear codes/etc and report back tonight with more findings.

If it was me and I wanted this thing to be maintainable long term instead of investigating custom wiring until the end of time, I'd buy the swap board, another wiring harness, and replace the bypassed wiring and switches back to stock, BUT THATS JUST ME.

This car doesn't have an aftermarket stereo/amps in it does it? It kinda sounds to me like there was a power surge that fried something, and my only guess is a wiring fudge.

I've considered this, but even the swap board wont be that straightforward, as its a BEL engine and ME7.1.1 ECU, the swap board only directly supports APB and ME7.1 ECU, for my setup id still need some repinning/etc. Plus, who knows if the body-side harness is pinned like OEM or if it was repinned for the swap. All stuff I will find out in due time i guess. If i decide to keep this car long term after figuring this thing out, the 2.7swap board is definitely on my list.

I have an aftermarket headunit, but it was unplugged during all this (i was dismantling the center console to get at the yaw sensor which was faulty), so that cant be it. As others have said, the swap wiring is the top suspect at the moment.

Might as well ping @nefkntym in the meantime and ask if this looks like a familiar issue.

I giver zero fucks about what it says over the pond. Most of europe has a common sense law on the book in every country. USA does not so we are stuck dealing with idiots that have to remember not to drink the content of the battery.

Don't be so confident just yet ! There are many more idiots here in EU than you'd usually expect :) - especially the Eastern side.
About the thread... no "Press Clutch Pedal To Start" on my 2002 A4 as much as I can tell.

[imabigdipper]

Ok, I'm back. Cleared all DTCs, and went for a brief test drive. Made some new discoveries. Heres the faults that remain and the info ive gathered:

Important Fault codes
ECM: Implausible signal for speed sensor
ABS: Steering angle sensor, Terminal 30 supply voltage intermittent
HVAC: Implausible signal for duration of ignition off time
Instruments: Terminal 15 implausible signal

Important info
1. Turn signals/hazards don't work
2. Mileage in VCDS/ECM no longer matches cluster mileage. (VCDS: 136,999mi, Cluster: 137,003mi. Test drive was around 4 miles, so that checks out). Could be related to ECM speed sensor fault.
2. ECM is in hard limp mode. Drives normally until I hit around 3-4k rpm, then cuts power and wont let me go above that RPM. This could also be a result of the ECM speed sensor fault
4. Cluster output test shows that all gauges/MIL lights are indeed working.
5. Same symptoms as last time. No CEL/EPC light with ACC on. Car turns on but speedo and tacho still dont work, still yells about oil level, etc.


Ok, so more codes pointing to a cluster issue, cluster/ecm comm issue, or wiring harness issue.
Did a quick search, and seems like the speed sensor fault can also be caused by faulty cluster/ecm comms.
Not sure about the steering angle sensor, could be from me pulling the steering wheel off, or another cluster comms issue. Will pull the wheel off later and redo all my connections to double check.
The HVAC one is confusing, seems to point to some kind of ignition switch issue. I had to unplug the climatronic unit it to put in my new yaw sensor, and plugged it in after clearing codes, so its probably related to that if I had to guess.

Cant find much info on the terminal 15 implausible signal fault with regards to the B6 chassis, but VCDS points to a damaged ignition switch (unlikely) or damaged wiring harness, not surprised. Looking more and more like a wiring issue, will probably have to start tracing wires/grounds/etc

I think my next steps are to pull the cluster out, reseat connections as a hail mary, and then start checking wires when that inevitably doesn't fix anything. Anyone have any other suggestions as to where to start?

I giver zero fucks about what it says over the pond. Most of europe has a common sense law on the book in every country. USA does not so we are stuck dealing with idiots that have to remember not to drink the content of the battery.

You know that we all respect your knowledge but you have an issue about being corrected and firing back with your anger. Try to see the good about information world wide as your knowledge is appreciated world wide but anger is not.

Anger? No anger that's just how I talk lol. It's all good Larhal. I don't mean I don't care simply stating that for USA market such a message is present. However if there is no MIL on with KOEO it could be a sign of a ecm failing. Especially me7.1.1 on a 2.7t.

Ok, so to test this, can I borrow/buy a ME7.1.1 ECM and just swap it in to see if that resolves the issue? I assume I'll have to either delete IMMO or do some coding for this to work.

Can I also do the same for the cluster, just buy/borrow one to plug in? Are there immo/coding concerns there aswell?

He should really get to your shop. Ct isn't that far away from you, Maybe 3 hrs. Max as I recall. Use to run from Philadelphia to Groton in the early 70's.

Believe it or not ive met him before by coincidence lol. He bought a standing desk from me on FB marketplace and made the trip all the way to CT. Saw he did cluster repairs on his FB page and we started talking VW/Audi stuff. He actually came in the middle of me replacing the alternator on this very car :P

This may not be fruitful, but just an idea. When I bought my 2.7 for my swap I bought a kit with everything from this place:

https://audis4parts.com


They build custom swap harnesses along with various other swap parts. I opted instead to use a stock APB harness and ECU with the swap board, however you might call them to see if they have BEL experience. I don't know if they ever sell BEL kits or harnesses, but the owner Phil Roberts is a great guy and extremely knowledgeable on the 2.7 swap. Maybe you could send him your harness and he could rebuild, and or confirm its good, or at the very least point you in the right direction? If you need parts like an ECU or cluster I'm sure he could source them. I'd give him a call either way and maybe you could pick his brain. I bet he'd talk to you for free, but if he does though, try to send some business his way.

Ok, problem fixed. Embarrassingly simple oversight on my end

The adaptation channels for the Instruments module somehow got wiped (channels 60-62). Was combing though the instruments module and realized the powertrain databus installation list was set to 0. The second I saved the correct coding, my EPC and CEL came on again, speedo/tacho worked, etc,etc,etc.

Creating this thread was definitely a bit of an overreaction on my end, I saw some scary fault codes and immediately thought of the worse possible scenario lol. Definitely relieved that it was an easy fix, and embarrassed that I didnt catch it sooner.

Oh well, you live and you learn. I appreciate everyone's help nonetheless

I just saw this, I am glad that you got it figured out. I was going to say to check the adaptation and/or the coding for the cluster. Either can kill the tach signal. If I remember correctly, it has been many years, the V6 cluster has two different ways to get the tach signal from the VR sensor on the bell housing depending on the year model. I believe the cutoff was 2003.

Any at rate, I am glad that got it figured out. Was there errors with the car when you bought it from Tristan? Seeing the video, it sounded really good when you started it. Awesome!!
