I took the polo gti in for its 15k service today and was told after i complained about the dsg slipping that the car had a tune and the clutch packs were slipping at no fault of their own. I purchased the vehicle recently from the same dealer and the vw service tech assured me that my car was definitely tuned, i wasn't so sure until i drove another my13 gti they had on the yard and now I'm convinced something has been done to my vehicle by the previous owner. So how do i find out whats been done? I also thought APR tunes still weren't available for CTHE engines as yet. A quick call around to Giac tuners and i couldn't find one who could remember a 13.5 gti. VW cannot see on their diagnosis at the yard whats been done but did tell me they can send the data to sydney to be analysed ,but if they confirm parameters have been changed in my ecu they will void my dsg and engine warranty , so I obviously told them not to send the data but I'm at a loss at what to do to find this out?
any ideas??
