    Audi A5 2.0TDI Temp Gauge Fault

    Hello Over the weekend my temp gauge started playing up, as in the temp would get to 90 as normal in idle but then if I put the heating on or started driving, the temp gauge would go down. Drove it to work this morning and it didn't even get up to 90, so I'm guessing it's the thermostat that's...

    Car not reaching running temp? :(

    Recently replaced the coolant flange at the rear of the engine and hose to the heater and filled up with new coolant if that could have anything to do with it. I've tried bleeding the system twice to see if that helps. Basically the car used to get to 90c on the gauge and stay there. Now it...

    Heating blows COLD ONLY, engine temp etc all normal... Help!

    Hi all, I have a 2.5 TDI V6 A4 Estate and the heating blows only cold air out! The engine warms up to 90 within 10 mins or so, does not over heat and runs like a dream. Garage has checked over the radiator etc and no issues there and they reckon it could be that the thermostat is stuck open...

    What model thermostat for 8P S3?

    Called a well know Audi garage in Reading to get a quote to replace thermostat - it had previously been diagnosed as needing doing by the guys at the Phirm. They are a bit too far out for me to go though so looking local. Lady on the phone said they couldn't quote as they didn't know which...

    Hello, I have a 2014 A4 Avant 2.0TFSI Quattro S-Tronic which seems to be struggling to get up to temperature, it just hovers around the 70 oC mark, where I'm sure it stayed at around 90 when I've noticed before, I'm hoping this might explain the poor MPG as well! My questions are: Does...
