OH NO !!!!!!!!!!!!!!!!!!!!!!

It seems my problem was due to the wrong grade of oil being used at my last service! And I thought I was being paranoid. I wont name the garage....yet. I'll give them a chance to admit the mistake they've made and put it right (i.e. reimburse me for the repairs to be done by someone who knows what they're doing and the cost of a hire car).
The repair bill is going to be in the region of £1500 and I'll be spending another £100 on a hire car!
I gave up with VAG-COM in the end, got no error codes and I'm not good enough to use the measuring blocks and scope properly yet. (Any one got any info on this btw)
I found a small local VW specialist, who seems to 1: know his sh!t and 2: actually give a sh!t. So i'll be going to him from now on, all going well.
