As the title suggests, the wife's car appears to me missing on at least one cylinder.

I have had it into a local independent in Aberdeen and they have not been able to give me a reason for it and have tried to waffle on about how it may be any number of reasons - all of which sound pretty costly.

They even say that the diagnostic tool was unable to identify the problem.

The garage I went to was Bavaria Auto Verk (BAV). Anybody used them before and how honest have you found them to be?

All pointers welcome.

They have just ran a code check and found nothing so choice not to look any further, too many people think that a fault code is the answer. It's a pointer toward the problem but could be caused by something else.

Basic mechanics for me here check plugs and coil packs would be my first choice

Agree with above or worst case scenario it could be the high pressure fuel pump failing... in summary spark plugs, coil packs (highly likely), injectors , HPFP.
