Does anyone know what the dealer actually does for the Upper Engine Clean Process? I know another make who has a Throttle Body Service. All that involves is the mechanic taking off the air cleaner housing and spraying a can of Gumout into the air intake for the throttle body.

I was hoping Jaguar's Upper Engine Clean Process was more involved than that.

 

I think that can only be answered by the dealer?
I would forget it myself.

If your worried I would run a camera into the intake and look at the back of the intake valves to check for build up.
Do you have any problems?

No problems at all. Basically asking for future reference.
