Detailing my allroad cost me 2000 USD++

[HenrikMeister]

First of, apologize for my english as its not my native language.

I delivered my car to a detailing service on Monday. They wanted the car at least a couple of days.
On Wednesday they called me and said that they couldn't release the e brake, which meant that the car wont move.
I then drove to the place and took a look. And the e brake was engaged, and neither of the guys engaged the e brake in the first place!
So the car was stuck...
I removed the battery waited 10 minutes and connected it back.
We finally could release the e brake and drove it back to my place.
Whilst driving the Allroad back home, I got a couple of errors, "Parking brake malfunction" and "ESP" error.
I've had this errors before when I picked up my car after oil consumption service some months ago which disappeared after a days driving. I think I had 8 errors in total that time iirc. That time i thought it was something to do with engine bay wash (as the guys who did the oil consumption fix said they did that before installing the engine back). Those errors havent appeared a single time after that.. till now.. the detailing guys said they did an engine wash. I was kind of relieved because I knew that the errors will disappear after a days driving...But it didnt.....
The same day i picked up my car from the detailers, I parked my car at work. After 4 hours I wanted to try to start the car.
I went to the car, tried opening the doors with the FOB, no reaction... i took the manual key and opened the door, no puddle lights or dome light activated when opened the door. I only saw almost ALL lamps on the cluster..
Couldn't start the car, nothing..
Towed the car, now it is in a Audi shop.
They called me today and They told me that the car was using power while parked... thats why i couldn't start it, because of the heater module using power (for aux heat)... it needed to be replaced. It costs 2000usd. They where not sure if that was the solution, they also said they probably also need to replace the CAN gateway module, which costs even more!!
Holy ****. A lots of details i haven't written. Tried keeping this short guys.
My question is, was it a coincidence that i suddenly got all the errors at the detailers? I am thinking the ECU got wet from the engine wash. Audi haven't even looked at it (I asked)
What do you guys think?

No idea Hendrik, full fresh scan would help. Used gateway cost is like nothing and if something is draining battery full drain test needed to be done, not just starting replacing modules by quess! ( "They where not sure if that was the solution"). If they hook up charger, will car start and run ok or not?

I have the scan on a txt if people are interested.

Funny w, i asked them and they havent even tested the battery drain problem.
They charged it up yesterday, and ran the car. They haven't checked if the battery has drained power or not today..

After picking the car up after detail (went to the store)





Then left the car parked for 10 min. I could start the car and drive

AGM battery may end up with a day and no idea what might got wet under hood and damaged, everything is possible(i washed 3 times under hood, no issue), but webasto and battery manager have all many separate shut of stages, so car should start after 10min break if battery not fully dead.

I would test car with other battery, clear the faults and perform fresh scan after that, if still issue, battery drain test. If its auxheat, they could code this one off(disable fully, like its not on car) and see if issue is gone etc! Just by your story, i dont understand how they diagnosed its gateway or auxheat issue(they may just start replacing those due some error in memory) - its all from your wallet!!!

It just doesn't make any sense..
I took a quick look on ECU before towing (looked wet, was even a bit of leftover soap sud around)
And they are accusing of the CAN gateway and auxheat module to be replaced, which is located inside the car.....
I even told them that they should check it, but they said that "VAS is saying the modules throw errors, which needs to be replaced". BTW they are also reading a TPI which describes the faults, one of the reason they blame the gatway and aux modules.

I did a diagnose before delivering to the detailers, no faults... after picking up the car, aaaaalll of this errors and the car is having a extreme seizure.

Wet ECU=error on the modules??

I should test that out Gunnar, but I am waiting for the insurance company to hopefully pay the bills

I would get it diagnosed properly...

Id let the detailing company/business know that you suspect it happened there and bringing it to their attention. But at the same time, tell them that your not pointing fingers just yet until you get the problem diagnosed.

Do you have any governing body for consumer rights in Norway? because even if its diagnosed as wet electronics or they damaged something in the engine bay.. I would expect them to deny responsibility.

Lets hope so, cant see your fault anywhere.

And yes, wet ecu can trigger all kind of errors in other modules also.

Btw: aux-heat module is all-in-one unit under hood on picture 9-12.

[HenrikMeister]

Even if it was an engine bay wash that triggered the problem, whether if it was I or the deataling firm. The car should've withstand an engine wash. The detailing guy has done this for 10 years and knows when and where to be careful..
Yes, I have insured my engine and gearbox, Im not sure what its called in the state, but my car is fully covered.
there are 4 "stages" of insurance we could choose from here in Norway, The last stage is the most expensive and should be insured for almost everything. Even engine and gearbox failures, not sure about my fault, im not sure since its something about modules etc. we shall see

Thanks for the photo Gunnar!

Okay I didnt know it was THAT visible it seems... nr 8 tho, is that a module ? Perhaps nr 2.
Any partnr?

Nr 8 is so to say module for auxheat remont control(Auxiliary heating radio controlled receiver -R64) and 2 is just information sticker under hood(Duplicate plate for auxiliary heater, Indicates both technical data and auxiliary heater model,Bonded from inside to the bonnet)

All in one unit heater+module together is something like this, depends which version you have:

http://www.ebay.it/itm/252549401843?...164&rmvSB=true

controlled with climatronic via gateway probably(gateway dealer price probably around 300/400 in Norway, estimated quess)

[HenrikMeister]

Btw, here are the error codes after clearing all 64 codes

CAN network gateway:
01207 - Control Module for Auxiliary Heater (J364)

Heater & air conditioning:
01207 - Control Module for Auxiliary Heater (J364)

Auxiliary heater:
02245 - Connection, RF remote control
00003 - Control Module
02251 - Heater unit locked

Parking brake:
00381 - Databus Instrument Cluster
16377

ABS:
00473 - Control Module for Electric Park- / Hand Brake (J540)

Engine:

Have you tested this:
02251 - Heater Unit Locked
Possible Symptoms
Heater not working
Heater Module refuses to clear Fault Codes
Possible Causes
Fuel Level low
Possible Solutions
When found in Aux Heater module of Audi A4 (8K), Audi A5 (8T), Audi Q5 (8R), Audi A6 (4F), Audi A6 (4G), Audi A7 (4G) or Audi A8 (4H), unlock heater module by saving a 1 in Adaptation Channel 042, then clear fault codes.

If you had first, dealer has probably fixed procedure to replace unit(same like with mmi, they dont try alternatives, like guy who was qouted 1500 for mmi went to other "person" who updated mmi in emergency mode, voilaa 1500 save - just silly example):
1)00003 - Control Module: Defective
2)00003 - Control Module: No or Incorrect Basic Setting / Adaptation.

Sxxt situation, hopefully insurence will cover, if not, you cant even cancel repairs and make it with your own spares.



Edit: regarding first error:

Here it was broken wiring between gateway and aux-heat:
http://www.mytreg.com/index.php?/top...ost__p__167986

Not harm to check it as well, but if auxheat is locked and defective, it probably triggered this fault(01207) not like wiring, but who knows.

[HenrikMeister]

Thanks Gunnar, i'll have this in mind. Still currently waiting for response from Audi and from the insurance. So its too early to overthink things, haha.
I'll try to relax a bit. Hearing it will cost 2000usd+ to fix got my heart beating

You mentioned that the ECU was soapy... Do you have a cracked cover for the Ecu plastic box?
If water gets into the plastic box there is a big risk that some of the relays under the ECU is fried.

In my B7 this was the case and after replacing a 10$ relay the car was like new.

Open the plastic box and look for standing water in the bottom of the box under the ecu. Check the function of the relays if you find water/moisture.

Good luck.

Yes I saw soap suds around the ECU right before the tow guy came.. So I didn't get to look closely as it was night time..
I mentioned Audi about this but they where relying more about the TPI and their scan tool..
But I totaly agree with you, I will mention this if they dont find out

Edit: I didn't even see any plastic box covering the ECU iirc

I had my local audi dealership detail my engine on my '09 A4 years ago and I was made aware that it's possible to fry the electronics if water gets in the wrong place. In my case I had to have all my coils and injectors replaced. I'd be willing to bet money that the wash did it..... you're taking the write approach though considering your insurance. I would let the detailer know......and needless to say, never get your engine washed unless absolutely necessary and you are involved to tell them they need to protect the ECU module and the top end of the engine (injectors and coils). Just because they say they've been doing engine detailing for years, you don't know whether they just got the new kid they just hired to do it. This can also apply to tint....since many amps have been fried from water from the tint process making it's way into the trunk well where the amp is. just my $.02

[HenrikMeister]

Good words Crucible.
This guy is a lone wolf, he gets a lot of costumers with ferrari's, lambos. It was a long waiting till it was mine turn.
I have told him this. And he is aware.
But not yet got a confimration from Audi what actaully triggered the problem. So I cant say something for sure.

Anyways, insurance got me covered. The final price for the repair costs 3.1k USD.
Thats what I pay for car insurance per year.
Deductible 700 USD.
Thank god.

Looks like you car is fixed now - from this! Which parts they replaced finally?

They replaced the Control Module for Heater, i was told that their was a TPI of the problem.
It was using power while the car was parked and locked...
So far so good. On to the next problem, which is the sunroof..
