Hello. My 2022 RS5 coupe is currently at Edinburgh Audi for a service and its first MOT. It is still under manufactures warranty. It’s got a full ASH, all work has been done at Edinburgh Audi and I’ve had the car since it was about 7 months old. It’s runs great, no issues and has very low mileage, around 7,500. 
 

Here’s the thing: it’s failed the MOT due to emissions. Initially they said they’d fix it under warranty, but when they hooked it up to their ‘machine’ it came back with a ‘TD1-Engine EMC Modification (Tuning) code which is now inactive. See attached file. I had absolutely no idea such a modification had been carried out, therefore it’s been done during the first 7 months before I got the car. 

Because of this, Edinburgh Audi won’t do the work to get it though the MOT under warranty. I’m having to pay for it. I doubt they can prove it’s this brief ‘tune-up’ which is causing the emissions failure and at the time of writing (0310hrs - can’t sleep for worry!) they don’t know what’s causing the emissions issue. 
 

I feel as if I’m getting shafted through no fault of my own. Surely this code would have shown up when it was at Edinburgh Audi for preventing services? I’m preparing myself to be hit for thousands when they eventually find out what’s causing the emissions failure. 
 

Any advice would be welcome as to where I stand, though I am, as mentioned, preparing for the worst. 
 

TIA, Glynn

Did you buy the car from Edinburgh Auto or from a private vendor?

Privately. The guy owns a mobile home sales/hire place. It was his car. Got it back earlier today. It passed after some work. £190-odd so happy with that. Not under warranty obviously and I now can’t take out an extended warranty which was the plan, but could have been way worse. I’ll take it. 

Unfortunately a private sale leaves you little chance of recompense.

It's strange a modification has been done on such a new car. Did he use it to tow caravans by any chance?

Yes, it’s a risk. That’s just what I was thinking. Doing that modification on a car a few months old. Or it could have been done as soon as the first owner got it, I don’t know. Warrant invalidated as I now know. Absolute madness as far as I’m concerned. I don’t think he pulled caravans with it. 
 

The ECU is at factory settings and the software update they did when it was at Edinburgh Audi went without any issues. I was relieved it was only a couple of hundred quid, rather than the thousands I was expecting. All seems well though. Hopefully it’ll stay that way.
