pulling my hair out slowly,cars a w reg quattro,done all the normall tests,no fault codes,replaced coil packs,plugs,dv valve,n75 valve,green temp sensor,samco intake pipe,checked for air leaks etc,remapped ecu,(fault was there before remap)car has a very slight miss on light throttle from cold and then when on full throttle when hot seems to hold back/missfire and it feels like the boost comes in and out,car idles fine etc,dont think its fueling,could be the maf but thought that would bring a code up???someone must have had this problem and fixed it as i dont want to just keep buying parts for no reason,any input would help,
cheers
