So, i've done a bit of research and it would appear that the G62 temperature sender sends 2 signals;
One to the on board temperature display on the dash and the other to the ECU (Please correct me if i'm mistaken!)
My issue is, if i connect via OBD, the temperature is reading between 110-118 Degrees in operation, however the on board display sits firmly at 90. The sensor in question is new (part of a new thermostat housing) as is the thermostat. The car is showing no signs of overheating, however I am getting a noticable loss of power once the engine is warm. When cold, the car is very nippy and the engine sounds quite nice, once warm, the car struggles to accellerate (No fault codes)
I think the ECU is recieving a high coolant temp signal and retarding the ignition timing to suit (If such a thing happens)
My first thought is my OBD adapter is giving false information, I'm getting my hands on VCDS and a cable to suit. Other than that, i'm going to borrow a friends laser temperature tool and check pipe temps etc.
Has anybody else had a similar issue??
