It was the thermostat !! Thanks guys

I’ll let you know the outcome chaps . Thanks for the input Andy

My thoughts also Steve . I’ve got exactly the same model car and had to replace my thermostat last year . Pig of a job !!

Evening chaps, just had the cambelt and water pump done on my sons 2012 A3 8P 2.0 TDI . Mechanic said it took just over 4.5 LTRS of Coolant and may have an airlock but have heat in the cabin . Drove it home with the heater on and temp reached 90 degrees then when sat in traffic with blower on the temp reduced to 75 degrees (not normal as it should maintain 90) got home checked the level and managed to squeeze in another half litre. Took the car out along the motorway a little later , car got up to 90 degrees , heater nice and warm , and again at traffic lights temp reduced. Got home , removed the coolant cap , no hiss , as it wasn’t pressurised , coolant Luke warm after indicating 90 and 20 miles of motorway driving ! No coolant loss this time . Could it be airlock ? If so how to get rid ? Or thermostat ? Thanks

Thank you 👍

Evening , As per the title pls . Looking for a N/S front fog light grill for a 2012 A3 8P sport back with chrome trim pls . Thank you

Ebay

Thank you very much for the info. 👍

Thank you Gareth , I was looking at Brembo , £190 for the full set up . I will make sure mounting faces are clean along with a strip , clean , re grease of the callipers . Thanks for your input . PS another brand that seems popular is PAGID ?

Hi Gareth , Want to replace discs and pads plus fluid change . Just want quality parts and standard is fine or an upgrade not too bothered . Thank you

Evening , Need to renew brakes , front & rear . Which brands do you recommend? Want to replace fluid as well . Standard dot 4 ok ? Thank you all

LED bleed through causes this and is a common fault . You can get the instrument cluster repaired but if it doesn’t bother you leave it .

Pleased to report its all back together and the needle is sitting nicely at 90! Thanks for your contributions chaps

Quick update on this . It’s a pig of a job !! Removed alternator and air con pump to gain access . Maybe easier removing inlet manifold and throttle body but will need a new gasket if you go down that route . I’ll update when we have it back together if it cures the problem . As per Gareth’s advice you do indeed require an extra gasket . Thank you Gareth 👍

Now it’s stop raining I’ve managed to have a good look at the thermostat location . It appears if the throttle body is removed it will give good access and the alternator can remain . Any words of wisdom before I start would be much appreciated. Rgds Andy
