Thanks for all the comments, I have passed this lot on, but awaiting porsche's response to paying/contributing towards cost first.
I said just clean the maf first, but car is 75 miles from me, it's going in this week, so will let you know how it gets on, I told him to get a 996!!
I just wished he had got a cossie, but he's a bit too much don't want to get his hands dirty type, ie office waller, he's doing a robin hood, fully electric though, and seems pretty eager so far!!
