Question about 2005 Audi A4
Got code P0118 indicating engine coolant temp circuit high input. Also have recall by Audi for ignition coils. Can the two be related? I am not sure which is causing my check engine light to come on. Car is 2005 Audi A4 1.8T Quattro.
Temp gauge goes to 12 o'clock position and does not hesitate up and down.
Hi, the sensor on the engine (right at the rear end of the cylinder head) has two separate outputs. One drives the temperature gauge and the other provides data for the engine control unit. The output for the engine control unit is almost certainly faulty and the sensor will need to be replaced. It isn't an expensive item and's not time consuming to replace (1/2 hr) - so you could ask Audi to do it for you when they replace the ignition coils.
Hope that helps Matt..
