Having some troubles with temp gauge, so going to change the sensor. After the change, should I bleed the coolant system?
Is it enough if I open the coolant cap, start the engine, and put the heater max?
Also having some other troubles... Sometimes if the engine is warm and I stop the engin for eg. fueling, the car wont start without loooong (~5sec) starting. That has been happened about 5 times, but today the engine stopped on trafic lights, and needed long start. Always the EPC light comes on, but after next "normal" start it disappears.
I read some topics that it could be the crank- or camshaft sensor, am I right?
Car is S3 (BAM).
I dont have VAGCOM...
