So, I’m after a D9R 105 apparently. There are some 23 variants of the 505 both petrol and diesel, not all will fit. Others I have come across are Cevam 3482, Unipart GXE4981, Valeo D9R 95, the list goes on. Digging a little deeper the quoted Kw ratings seen to vary from 2.2Kw to 3Kw but all still show compatability. Umm what to do!!!!!!!!!!!!!!!! I would normally opt fot the higher rated unit but for something so simple how can they be so different? Who and how were the measurements taken? It’s enough to drive you to drink.
