The 1.4 TSi engines are in theory brilliant, but the execution of them for VW/SEAT/Skoda is horrific. In 2 years mine had the following
New DSG Box
6 x sets of plugs
3 x Radiators
Piston Rings had vanished
on top of that,
Used 1 litre of oil every 500 miles
Constant overheating
EML on if over 5000 revs
Constant Misfiring
It was just a nightmare, and SEAT didn't want to know anything. After letters addressed to the Director, still nothing came of it. Disgusted in SEAT. I'll never return.
However the cars were in theory a brilliant car.
