Just checked my invoice list - Yes, original part 55198357 put in, from eper this is same as GTA. GTV 3.0 & 3.2 get 55198358.
Pomeo - No need to adjust heater if overheating, the 166 does this itself. I experienced this on the M25 last year in a long traffic jam, the Super started overheating as I sat too close to car in front! In my panic I did nothing
, the 166 went into an override mode and put heating up to hot and fan upto full!
