Problem I have is the car is taking longer than average to warm up, during this process with the
blower on low and on max temp and if I'm in traffic the temp will go down back to cold.
Once warm on 90degrees again if in traffic or stationary the temp will drop down again.
I have changed the thermostat with a genuine replacement, filled the cooling system with
antifreeze/water and blead accordingly...the problem is still there
So I have also changed the engine coolant temperature sensor, lost a few litres of coolant so
repeated the process of filling the coolant and blead again.
Unfortunately the problem still persists!
Any advice/feedback will be appreciated
Car in question is a Audi A4 2.0 tdi sline 2007 B7
