So a few months ago I posted about having a ceased passenger turbo....well it's still ceased and the warranty company refuses to do anything without codes being thrown and a CEL. Pretty sure the guy who tuned my car made it impossible to throw a CEL. Only code I'll throw is a faulty back up sensor lol. How would I go about getting rid of my tune and a stock ECU. Assuming the dish will slow like a Christmas tree with lights on a stock file. My tuner passed away last year so I can have him delete the tune. Any input would help. Tired of driving with one working turbo. Car sounds and feels like a beater.

With a secured deposit I can send you one of my immob disabled ecu's.

they have flashes but will still throw codes

will it allow me to drive still? I'd have to throw the codes....Drive to the shop and have them confirm them with the warranty company. "Immob" seems like it won't let the car drive lol

You can drive forever

these are my test mule ecu' that work in any RS6

Dhall, what tune is on those test mules? What is your rental rate? Sounds interesting!!!!!!!

Daz's partner carries on his work from my understanding. PM me and I'll get you over to someone who can maybe help.

You can flash the stock tune yourself if you have any "dumb FTDI" or genuine VCDS cable. Being computer savvy also helps. :)
Immo should not be an issue if your current ECU has it active.

I'm not sure you'll get a specific error code even from a stock ECU. The failed turbo, if that's the issue, will not throw a code itself, it's mostly a hardware problem not electrical or sensor, just like the transmission does not always throw a code when it fails. I've had two transmissions tear themselves apart, no code except for temp sensor and input/output speed sensor.

I really think you're only going to get codes such as rich/lean/misfire with your turbo; are you not getting any of those now with the crap performance?

Just my 2 cents, maybe somebody can set me straight?

You should try another mechanic when you can, most of your posts regarding the shop seem to be rough with the quality of work and their understanding of the car, although they seem to be cheap, which could be a reason for the above.

I agree with Iswing. Both turbos work together to feed the same actual intake to all 8 cylinders. So the entire engine will simply have less boost. If the setup was each turbo only feeding half the engine then for sure you'd have issues the ECU would probably detect.

Thats a tough situation to be in. Since your warrantee covers the Turbo. Sounds like the insurance underwriter is clueless. May be time to spend some money on a letter from an Attorney.

im not throwing any codes what so ever having to due with the engine or electrical anything. The warranty company pretty much told the shop they don't doubt a turbo is frozen and not moving...they WILL cover it...just for a big repair like that they need a "code" or something leading towards the turbo besides the shops word. I'm only assumeing so a shop can't say the tranny or turbos are bad and then the customer gets new ones even tho the old ones were fine? It's the only shop anywhere near me what's worked on RS6s before. They've had 3-4 at the same time in their shop... My tune doesn't throw EGT codes or Lamda codes because they are codes out. The shop says any type of code other than the "rear parking senor" going out would help!

It should throw a code.

Esp if it's running as bad as you say.

I call bs on the service contract. If the turbo is dead and you tear it down to find the dead turbo. They have to cover it.

Now mind you the tear down is on your dime until the covered part is found. Typical situation

Have you checked your EGT sensor temps for the passemger bank?

I ran logs a couple months back and posted them...I know the lambdas just showed "0" because of them being coded out. I don't think the EGT temps looked too out of whack, or if they did no one mentioned it.

I got em all.

How fast do you wanna go?

True story....long time forum member from so cal called me last year. Seems he was called out by a friend to race his RS6. He was already flashed.

He got beat and promptly called me about what to do.

Datalogged the car to make sure sure it was running to spec. Then I sent him a ecu to take care of the rematch.

Took .4 tenths off in the 1/8 mile and smoked the guy.

RS6 FTW

I should go look up my thread beating the co workers Grand Sport vette again. And that was with my beater RS6.

I hesitate to guess which tune it was.. :P

Sent you a PM DHall. I'm interested in another ECU to try and see if it'll throw some codes we need!

EDIT: I think I sent you a PM. Sent it twice but doesn't show in my "sent"

I only ask in that I had a passenger turbo that failed on one of the rides here. I had a CEL that threw because of excessive temps on the passenger EGT. I attributed it to a bad sensor at the time, but in fact the sensor was doing exactly what it was supposed to as it registered high EG temps due to a failing turbo. I know a few board members have said they prefer to code out the EGT's due to the sensor failure that occurs occassionally, but I'm a long time supporter of keeping them coded in for just this type of a reason.

the EGTs are 100% codes out. Gonna try and borrow a non coded out ECU and see if that dies the trick. I'm really wanting to get this done!! Sucks driving an injured car!

Can they put a scope camera down the intake below the MAF to 'look' at the blower side of the turbo? If they nudge the blades it should spin, if it dose not move they they have their answer!!!!!!

They oretty much did that. They told the shop that a repair that costly they need to have a code thrown pointing to that being the issue. He was like "sir I'm trying to spin it and it's not spinning" but they didn't care.

gonna get a spare ECU from DHall and go that route

Still trying to get my ECU back to stock form! No luck so far! I have a DimSport MyGenius programmer that has a stage 1, stage 2, and STOCK file on it.... but it's VIN locked to another RS6. Eurocharge won't unlock it unless I pay $150 PLUS the $599 for a new tune (I don't want a new tune). DIMSport themselves said they don't do it and to talk to the tuner shops. This is insane! Never heard of so many issues trying to remove a tune! I emailed the guy who took over my tuners shop when he passed away and haven't heard back from him. Got a couple more shops to email/call and then I'm completely out of ideas!

The trouble you're going through is normal and to be expected. You need to use the source company/person to fix/remove the custom tune you have. So yes, go back to the source. Other companies will charge you money because it's not their tune. People are saying the guy who took over the shop has been helping others, good luck! It can be a bit dangerous at times dealing with small tuners where you don't have more company support.

It's clear the insurance is trying not to pay if they've seen pictures of the turbo not working, along with mechanic testimony. Hope you can get that code thrown for something and get them to agree!

Well. I posted the instruction and links on the previous page. I'm puzzled why you didn't give it a try or at least ask a question or two.

This can also flash your ECU:

PS. I have a feeling that this whole DTC thing is a shop's way of finding an excuse to screw you over with the warranty. "Oh, look, it has a DTC for deleted cats! That's why your turbo failed, it's not covered. Good bye, have a nice day."

Sorry. I read the info but am not computer savvy by any means. The only computer we have in the house is a cheap $299 Black Friday special. I use it to do taxes on and run logs/codes that's it. I have a Ross-tech VAGcom cable....I'm assuming that's like the one in the eBay link? I'll re-read the article again and maybe have a friend look at it as well.

E-bay link is for the china MPPS clone (flashing tool).
It is quite easy to use, and works 100% with the RS6. Comes with its own software as well. Basically this is just another option of getting your ECU flashed.

VCDS cable looks a bit different, but since you know how to do logs & codes, I believe you do have it. :)
The "guide" I linked above is for using VCDS & nefmoto flasher. But since you're not that good with computers, getting MPPS might be easier.

So after complaining on a pretty much B5S4 fanboy Facebook page I found a backyard mechanic kind of guy who knew how to do the things you guys told me to do (check the n275s, use me7 or whatever to make it stock tune again. Etc). Drop the car off to him for two days....got the car back and it's running what seems to be flawlessly! Lol. The big name shop wanted $8k to new turbos from the warranty company. This guy charged me $100 and replaced the DVs with upgraded ones, replaced some cracked boost lines under the intake, and did something to the passanger wastegate? He said it was rusty or something.

Either way I ran logs before I drop the car off and ran logs again when I just picked it up. World of difference! Specified boost was 2080 when actual was 1250 before....now specified is roughly 1890 and actually is 1800. Not sure why the specified dropped but I don't care since it's running fine. Taking it to the dyno tomrrow to compare what it made 3yrs ago when it was perfect to what it does now. As long as it. Asked remotely the same power I'll probably clean her up and list her for sale....still has the warranty until this November I believe but the headaches and everything she's given me the last year or so has taken its toll! THANK YOU everyone for your feedback and assistance! Will update you after the dyno with the results!

Probably because it has a stock tune now? :)
Looks a bit high for stock, though.

i believe he put my Viper tune back on it. I gave him all the files and whatnot I had. He said the Viper seemed smoother thru all RPMs than the other tune I had. He changed it to stock tune to see if it would throw a code and all it did was an 0s code. The Viper tune was supposed to be 16psi according to Rich at Viper. But rosstech shows almost 13psi max....me7logger that he (the guy who fixed the car) uses showed it at almost 18. So idk what it's actually at. I think stock is around 8-9psi.
