V280 W638 - 1998 - Rough Idle - Coolant Sensor
I have a 1998 V280 Auto bus, with 7 seat, It has a very erratic idle, from normal to near stalling. I have changed the fuel filter, drained all the fuel tank (it was very clean !), blown the fuel lines.
I dont think its a fuel problem, I don't think its a ignition / spark plug problem
i have read a few words of advice points to the coolant temp sensor. I just need to know where it is, or get a picture sent through. (based on VW engine ?)
if coolant sensor is not the fix, then I was going to try a MAF sensor.
The car does have the old round pin socket, but i dont have an adapter for my code reader.
any help appreciated.
