I recently (less than 6 months ago) upgraded to a Grimmspeed intercooler since the stock intercooler was leaking. Since then I have had no problems. 2 weeks ago the sensor that controls the AC compressor malfunctioned causing my compressor to cease up. I have since had the AC compressor, condensor, extraction valve and the sensor replaced. I got the car back yesterday and am noticing a burning smell from the intercooler/inlet pipe and white smoke coming from both. Is this normal for this kind of work or did the shop do something wrong? My concern is that this shop has been very disappointing every step of the way and am very close to taking it to another shop to inspect the work.
