Hi everyone...

I have another question before I put in my order for a 2011 A5 2.0T. I've read a lot of info on the carbon build-up problem on Audi's direct injection engines. Is this an issue that still exists on the new models? If so, how susceptible is the the 2.0T engine to carbon build-up? Is it something that would keep anyone from buying the car if they knew about it before hand?

133 views so far and nobody has said a word? Does that mean this is still an issue that plagues these cars? Or is it a non-issue and that's why nobody is talking?

The 2.0T doesn't have a bad carbon build up issue, mostly just the 3.2 v6

Beakerz

Really? I thought all of the direct injection (DI) engines were affected by the carbon issue?

ryan_qttro

I would say the 2.0T has the least amount

Not sure it's on the A5 but Audi put an extra injector in just to address this problem. I'm sure it's not going to be in listed in the specs but it's there.

Hi, can you direct us to where you read this or have you actually seen this injector on an Audi? I just read another comment to this effect the other day on another forum. I'm thinking this is wishful thinking (just because Toyota did it?), but would really like to know if it is in fact true.

Thx

I wasn't clear in my last statement [typing from iphone]. However if you look at the new Q5 you'll see it, not sure on the A5 though.

Beakerz

That's good news. I read that Toyota/Lexus took that approach on their direct injection engines to prevent carbon on the intake valves. I didn't know Audi had done the same thing.

Actually the 4.2 in the RS4 is pretty horrible with CB issues.
