Thanks Nolimite39.

I just got a call from the shop. They took the fuel tank out, drained all the fuel, new fuel, cleaned injectors and found some very fine metal shavings in them indicating possible pump wear. Considering whether a new fuel pump is required.

All running fine now and all Vanos codes gone so I may have finally had a win!

They are going to drive it a couple of days before I can have it back.

I'll prob swap out the spark plugs they put in though......
