Did you find out what the engine knock was? I have the same on mine which has just started and finding the problems is costing lots!!

 

[crezz]

it could be the cam or it could be the crank, saying that it could be many things

Apparently the mechanic has told me the knocking isn't the big ends, nor the dual mass flywheel. For me the knocking is too deep and slow to be tappets. But still I have to pay for the labour to check it all. Oh, and a new flywheel!!

it may be the crank itself that is at fault or maybe a shim has broken away somewere im only guessing though

Well I finally found out what the problem was. And boy it aint cheap.

The cam had worn the hydraulic tappets, all the way through one of them. That was what the knocking noise was. (that surprised all of us how that sound was so different to the usual).
Well, 1 valve, 8 hydraulic tappets and a cam gone to the race track in the sky. Was gonna cost about £1600+ to get it fixed. But managed to find a place to get a re-con head for £450 + VAT and delv.

Note to others, do not buy one of these cars unless you are very sure the correct oil has been used. £7000 then six weeks later £1000!
Definition: irony: I sold my last car because it was going to cost me £1000 to get it up to scratch, I spend more money to get a better car so I wouldn't have to waste money on repairs......D'oh!!!!!!!!
