I recently had my 77tsi serviced last week, they called me during the service to say that there was carbon build up / gunk in the intake section of the engine before the intake valves.......

I said ok to them cleaning these deposits from the engine...........

From what i understand this tends to affect direct injection engines mostly due to the fuel not cleaning the valves/intake ports.......

This would exclude the 63kw 1.4 N/A as its port injected.....

Has anyone else had this happen to their engine???
