Hi Guys, The temperature issue has inherently got worse over the last couple of months. Initial diagnostics suggested it was the thermostat but replacing that did not fix the issue. I've had it in the garage and the overheating did not occur whilst the mechanic left the engine idling for a number of hours. It only seems to happen when at load, i.e on a run out. Garage changed the thermostat and has tried the water pump etc but could not identify the problem. I am not technically savvy with this kind of thing, hence why I thought I would try this thread. It's looking likely that I will have to secure funds to get Audi themselves to look at the problem which I'm sure you will agree will be quite expensive. It's just a bit frustrating as I've ran Audis for years without any issues and I'm at a loss. Thanks for your input though. James

I have absolutely no idea Gareth. I was hoping there would be a solution that I could identify on here. I could buy a new heat sensor and try the process of elimination bud

Hi bud, I'm familiar with the overheating smell but there is none when the car is apparently overheating. There's no steam neither. It's also been on a diagnostic and nothing has shown. My mechanic couldn't find a fault.

Hi Gareth, I think it was an Audi part that was put in. It was purchased through my local car parts shop. The car has been in the garage and the mechanic did loads of tests including a diagnostic and couldn't find an issue. He had it running for ages, ticking over and it would not overheat. It just seems to do it under load.

Hi Folks. I'm at my wits end. My 2010 A3 Convertible 1.6 is overheating. I've had the thermostat changed and had it in the garage but they can't find the problem. The water pump is working fine etc. After about 20 miles or so the temperature guage goes up, it fluctuates up and down and sometimes to the point where I get the red warning light on stating to switch engine off and check coolant level. The coolant level is fine and I'm not loosing any water etc.I'm wondering if there is some kind of sensor problem. When the temperature goes right up, I lose power and have no idea what to do. Any advice would be greatly appreciated. Quote Edit
