1.9 Tdi AFN Relay Help Please
I've recently got my A4 Avant Tdi 110 but haven't had a chance to post an introduction yet with some pictures...it's coming!
I could do with a bit of cheeky help first though, since doing a major service when I bought it I've had a problem starting it on cold mornings. There is no power to the glow plugs so I'm thinking it's the relay....but I can't find which one it is. My car is the facelifted version and the relay is not by the heater inlet as on earlier models. I'm guessing that it is one of the ones in the ECU box. Does anyone know which one it is? I'm thinking no 373 but not totally sure. If it is then I measure 12V on one side of the relay circuit and a dodgy 7V on the other. This terminal must be earthed by the ECU so if it's not wiring then it looks pricey! .....if I have the correct relay!
Any advice would be great, thanks.
