After having the waterpump in my car replaced, along with the radiator temp sensor, thermostate with housing and "both temp sensors" and the fan relay control unit, my car is STILL overheating. Is there anything else left to replace? When the dashboard water gauge is on just over 110, code 51 on the climate control shows 66 degrees. When I then set code 49 on the climate control, it says 82 degrees. This corroborates what the garage said, that there's a difference of 30 degrees roughly. The fans don't come on, and when I do get them on using AC blasting out, the temperature didn't seem to stop rising on the dash when I rev the car a little. Here's a pic of what looks like it's been replaced, I've heard the temperature sender is a relatively common fault, but it looks like it's been replaced? Do you think from the pic the sender has been replaced? Could anyone please give me any advice as I don't want to take it to Audi for about £500 if I can do it myself. This is driving me mad. I'd really really appreciate any advice that can help me get to the bottom of this.
