Hi, I have a 2006 A4 Cabriolet (2.0 TFSI 8HE BWE) and want to replace the timing belt. I got as far as the crankshaft pulley bolts and discovered that all the heads have badly corroded and I cannot undo any of them.
There are 6 in total and I believe should be triple square bolts but on closer inspection there is a mixture of both triple square and hex bolts (looks like on a previous belt change someone used a mixture of bolts!).
My question is, does anybody know what the correct bolt should be for my engine. I have searched the net and nowhere can I find a company that supplies the correct bolts for my crankshaft pulley. I believe they are triple square but what is the thread diameter and thread length? M8 is a likely contender.
Also I haven't removed them yet and was wondering what is the best way to do so bearing in mind there is only a 10cm or so gap between the pulley and the radiator in which to work (unless I remove the complete front end).
Many thanks to all.
