i got a check engine light number 1088 . ive had it for about half a year now and it seems like it doesnt effect the car at all . but the cel itself bothers me . anyone have any ideas how i can go about fixing this ? thanks

Tumble generator valve #1 (RH) position sensor circuit low input

-> you b0rked the sensor. They seem to be fragile: someone here b0rked one when fitting an uppipe; dealer b0rked my front LH one while fitting a new a/c compressor. You *may* be able to get just a new sensor (it's been reported that they are the same part as the throttle position sensor or 'TPS') or may have to replace the whole valve assembly.

Or you could do the 'DIY TGV delete'... search in the 'Factory 2.0L Turbo' forum
