I have just started getting that dreaded / annoying hesitation problem that 1.8 T’s suffer from and from searching the forum I see quite a few people have suffered from it, but the annoying thing is no one ever updates the thread they have started about it, if it’s been fixed or what fixed it!!!!
So my thoughts are we have a lot of guys on here ASN who are very knowledgeable and maybe we can put together a guide on sorting these problems out once and for all.
Here’s what happened with mine, since I bought her in December 2011, she has run well, until the dreaded Head Crack issues that AMK’s suffer from, had a brand new replacement head fitted in March, and she was fine since then, no problems what so ever… then 2 weeks ago I had the Clutch pedal snap, I got a replacement and had it welded so hopefully won’t happen again! But ever since replacing the pedal she has this interment hesitation between 3000 and 4000 rpm, just for a split second and then she’s fine, and at other times she totally fine rev’s cleanly through no hesitation at all, I thought seeing as the last thing I had touched before this problem was the clutch pedal I replaced both the Clutch and Brake switches (plus they are really cheap from Audi, old skool mechanics’ start with the cheapest fixes first), still no joy. I don’t have VAG COM yet, just ordered it today, so can’t log her yet.
The 4 Coils have been replaced by Audi Dealer (under the recall) a lot of the vacuum pipes were replaced when the new head was fitted. It also had new plugs then too.
I am thinking about replacing the MAF first or should I just wait until I get my VAG COM Cable??
Really hate it when she’s not running 100%...... Grrrrr. We have to be able to sort this annoying problem out between us.
Sorry for the massive post!!! But if people put down their experiences then we can get a bigger picture of this hesitation problem and get it sorted once and for all.
Thanks in advance
