New to this so apologies if it's the wrong section, feel free to tell me where to move it.
Ok I got an Audi a4 54 Reg 130 BHP tdi ( non quattro ) the other week, I've noticed my engine temperature rarely goes above 72 degrees, unless idle on the driveway, which then reaches around 82,then when i pull off goes back to 70 again. I've read on here it may be a stuck open thermostat, or a few sensors such as coolant, engine etc, i've checked my heaters and 21 degrees does feel the same as 29 degrees...
My MPG is terrible, i've put 10.3 litres in and gotten 72.5 miles out of her, according to torque cars 32 MPG, something must clearly be wrong, i don't always drive her hard and change just on 2k rpm on flat / downhill.
Yes it's cold outside in Cornwall where I live, 3 in the day today, and -1 when i have been testing it on hills- but most days 6 degrees, sometimes even 10 and it's still stuck on 70 even after a 30 minute run.
any advice would be great
