    Thread: 2012 TT RS turns over but won't run

      As I was ascending a hill at approximately 50 mph, the tach and speedometer froze and the lights went out in the entire gauge cluster. I made it home, where I parked the car.
      A few hours later, I attempted to start the car to no avail. The lights on the gauge cluster are still out and the car merely turns over but does not run.

      Audi is going to look at it tomorrow (they have no idea based on the above narrative what could be wrong) but I'm wondering if anyone has encountered this problem or has any idea what could be the cause.

      APR stage 1/down pipe, intercooler, and 8500 ci radar are the only mods currently installed.

      Appreciate any insights....

      That doesn't sound good! Seems like an electrical issue, and hopefully a quick fix.

      I'm very curious how Audi handles the repair given the ECU and other mods. Please keep us posted!

      Please keep us updated on what they find. Seeing that you have an APR tune, that could be cause for concern. Hopefully it is completely unrelated.

      Sorry to hear that, but the more I hear about problems after mods the more I hesitate to modify the engine despite how tempting it is!!

      sounds like a electrical fault like others have said. Same happened to my friends bmw 335i, turned out to be a dodgy relay.

      This note may describe mere coincidence but I had no problems w/the car (post tune and hardware installs) until I got it back from Audi after its initial service.

      I have no reason to suspect Audi and am leaning toward the idea that problem stems from an electrical fault. After speculating a bit w/a few local owners, there might be reason to suspect the problem could be related to the fuel pump (power, relay, etc). The oddity is that the gauge cluster lights are also out (though, no blown fuses).

      In any event, Audi has it tomorrow...my fear w/this kind of thing always lies w/the novelty of the problem. If the techs havn't seen it before, troubleshooting an unknown can end up taking days to months.

      Will keep this post updated...cheers and thanks for the concern.

      It sounds like it could be the immobilizer?

      Check.

      Well, while it may not have tripped properly, it certainly works

      I'll bring it up w/Audi.

      Thanks for the insight.

      Kind of a longshot, but on the original Gen I TT's, instrument cluster failures were pretty common. It was relatively advanced tech for the day and I guess quality control just wasn't there yet.
      Cars won't start because basically they're either not getting fuel, or not getting spark. Both are ultimately controlled by the ECU. Good luck.

      Interesting bit of history. As the car turns over, I suspect its being denied fuel. In any case, you touched upon a secondary concern: the tune.

      I should have something by COB today...will post then.

      I'm sure APR is keeping score on the odd-ball issues arising on cars with their tune. It could all just be coincidence and bad luck and completely unrelated but it's starting to grab my attention.

      I was one of those MkI TTs. Engine would turn over but not start. No tunes or anything, just a fried computer replaced under warrenty. Luckily I was in my driveway when it decided to quit.

      Ok...just a note to follow up. After dis/reconnecting the battery, the gauge cluster and security system are operating normally. BTW, something I didn't know but the gauge cluster and security system are linked into the same module. So, it came as no surprise that both systems failed at once...though, I'm still thinking there must be a root cause.

      However, Audi asked to keep the car anothe day to conduct further tests. Not sure I'm comfortable w/a on-off switch fix, either (even though all the diagnostics they ran indicate the car is running as designed).

      I'll have it back late tomorrow morning...will follow up w/anything they find.

      Once again, thanks to all for the insights and expertise.

      Reassuring yet concerning at the same time. I agree with you, there has to be a root cause.

      Just to refresh a story I told on here months ago....at about 8 months/10K miles, I got a CEL twice that went out on its own. Just to be safe, I had the dealer look at it. They ended up keeping the car for two days working with Audi tech support, and the conclusion was.....they didn't know for sure.
      Keep in mind, there's a relatively small number of these cars in the US. Sure lots of stuff is standard Gen II TT, but anything that's different because of the unique engine/drivetrain is going to be new territory for them. In my case they determined it was "probably" something emissions related but inconclusive as to what was failing. The car always ran fine and continues to. I'm going to guess they give you car back and hope for the best.

      Audi condemned the gauge cluster...new one being overnighted for install tomorrow.

      Oh boy, bad memories of my mkI days coming back. I haven't heard of any cluster failures in EU though so maybe it is 1) very isolated failure, or 2) dealer simply taking a shot in the dark.

      Any idea what caused them to deem the gauge cluster bad?

      My first thought was a bad cluster as well. Brought back some memories of my 2002 225 Coupe that would randomly shut down and refuse to start. And after getting towed home it would start sometimes and not at other times. I had an APR tune as well so replaced the ECU for a new one and got a GIAC flash. Car for solid for a few months and the problems started again. Replaced the cluster and all was good after that.

      MK1 clusters were made by Magneti Marelli I think- Italian electricals on a German car ...

      My 2004 was rock solid and I have not heard of cluster issues until now on the MK2s. Maybe TT RSes got a bad batch?

      you didn't get any grief about the ecu tune?
