Edit: solution/tsb found see (current) last post with pictures of tsb info so that if there is anyone else whom needs this done you have the # but I'm assuming mine had it happen simply because it hadn't been driven enough before the warranty was up whereas most other a4's if not all have already been reprogrammed. This is only if you ARE STOCK NEVER TUNED if you tuned and it happened, well that's your fault

Here's a link from apr's website which has the tsb release from AoA which is long winded, my pictures down below are short and sweet

Hey there guys, so I'm on vacation currently and not having owned my new to me A4 long enough to trust it I likely brought along my Ross-Tech cable and found something that is bothering me a bit. So here's how it came on

Wife and I had some down pouring this morning and were driving for probably 45 minutes in there, and there were some rather large puddles (unsure if it caused it but probably related) so we made a stop somewhere and I left my phone charger plugged in and possibly my satellite radio ( I use an external one for better features) and we were stopped for maybe 30-40 minutes, got back in and while we were driving short distance the EPC light came on.. Awesome news for a vacation lol. So we stopped again came back out, was still on (didn't expect it to go off) and the check engine light came on but car was running fine, so I didn't worry too much about it. Get back to the hotel and find this

Which then gets me very worried that my ECU just randomly shit the bed on me... So I reset the code and start the car again, logged block 004 for battery voltage and its reading fine (I'm assuming the battery voltage it reads is actually alternator output) it was around 13.5V the whole time, well at least at idle (I did a graph instead of log and was watching while driving so couldn't see exactly where it was at) saw no spikes or drops anywhere in it will I was messing throughout the whole rpm range so I pull into a parking lot, shut the car off turn on again, EPC lights back. Says this

So I clear the code, shut the car off turn it back on, no light. Shut it off turn it back on, light on, clear code try again and the light is back on immediately, do this like three more times and light is on every time now immediately (before it took two starts) Last code log is this

So what I noticed is that the voltage dropped each time I started (obviously) and the first code was under 12V, so I go look at the battery (since I just got the car) and I found the date code I couldn't find when I bought it, July 2010.... Car has 41k on it 2005.5, and is bare stock other than a symphony II+ radio and a K&N air filter, no tunes and it was owned by an old couple so I HIGHLY doubt they tuned it..

Does this point to the battery being toasted to anyone else and should I start there before worrying about finding a new ECU?

What voltage should I be seeing on block 004 to verify the alternator is working correctly?

Any other suggestions?

Thanks...

PS, probably gonna head over to walmart and find a battery :/

Battery check time. My bimmer had similar issues with electronics when it's battery was going bad, as little as 1/3 volt loss will cause issues with electronics. It needs to be above 13.7 volts.

[canadianA4B7]

My recent battery crap out was strange. Car was perfect for approx 10-15 min, about the time it took to get up to temp. When I believe the fans were clicking on car died. Mostly when at a stop I'm assuming the air flow while car is moving was keeping fans off (I don't know but I wud think that's how it works). It was all along the battery. It never threw a code or anything strange, just running fine and then nothing engine died car wudnt start. After it say for 30 min to 1 hour started fine and repeated the issue.

[pezgoon]

New battery didn't fix it, at least I feel better as my old one was bulging on the side apparently as I saw it when it came out.. Bad news is I don't think its a voltage issues as I had my wife resetting the code while I was driving, so I tried shutting the car off while moving to see if it had been fixed on its own, it recorded the fault at 14v
Heres the new codes

This was right after installing the new battery

And I left out the four others that were just in between all these, I don't think they matter

Anybody know how to find TSB's? or know anything about the TSB suggested by ross tech?

I'm thinking my ECU is going to need a re flash from the dealer?

This really puts a fcking damper on my vacation

[pezgoon]

Can anyone with a Ross-tech try and find out what their ECU's version/info is? Its under engine controller, advanced ID and looks like this

It would be very helpful in me determining my version to see if I missed out on a recall or something and for me to communicate with the dealer, I'm hoping that a reprogramming from them will correct it. Thanks very much guys.

Edited with proper info

[pezgoon]

No one has any info in regards to this happening with the car never being tuned? or where I can find TSB's? When I just put my info into AOA it said there were no TSB's or Recalls for the car in the last 15 years... I am sending them an email to see what they tell me

[mtroxel]

This was right after installing the new battery

If you didn't clear codes after swapping the battery, you will see a lot of "Power Supply Terminal 30" codes in several modules. I see it all the time after I've even disconnected the battery. That doesn't help with your checksum error. but it explains a lot of stuff in that post right after the battery.

I'd be happy to VCDS my ECU, but mine is chipped so I don't think I have what you need.

[pezgoon]

Okay I figured all those were simply because I had disconnected the battery thanks for the info, ya I would like someones who hasn't been chipped, I just remembered that I needed that info and I had my cable plugged into a car earlier today helping another AZer, should've looked while it was plugged in dammit!

[pezgoon]

Alright so some news on this issue, there was/is a tsb for it, tsb 2011732 sadly because I'm out of warranty it is nothing more than information but it does say no affect on driveAbility so I have no worries continuing ignoring it for now :) they did try to tell me that normally it happens with a tune and I told them mine has never been tuned and that my mothers car showed reprogramming and hers has never been tuned (mine showed none) as they didn't really wanna look into the tsb's as they kept saying that code wouldn't have one.
Here's the sheets.





So there is an update and I'm going to try and convince one of the dealers around me to lower the price or do it for free so we will see what happens
