Cheers in advance guys

That could be coil packs 2 and 6 but I have had this on these engines when the cam timing adjuster valves fail.

Cheers Crasher, I'm guessing 2 coil packs going would be beter than cam timing adjuster valves failing?

Is there an easy way of checking the coil packs? And which ones are cylinders 2 and 6 (probably very stupid question but apologies)

Also, if it is the cam timing adjusted valves going, what sort of job/cost will this be?

Thanks again mate

Yes but the cam timing adjuster valves are easy to change if VAG UK have any stock. They are around £80 each and are bolted in through the cam covers, quite an easy job to do.

Cheers again Crasher, is there an easy way of seeing if its the coil packs, or the cam timing adjusters?

Not an easy one, it is down to experience and lots of time studying measuring blocks.
