After spending a tonne of money on my car the last few months, it seems it wants to continually hack me off.
Driving home last night in reasonable but not heavy traffic, I notice the temp climb above 90. I was close to home so tickled it the last 1/2 mile and plugged in vcds when I got home.
Both the temp gauge and vcds were showing around 115 degrees. Initially when I got home, I couldn't hear the fans however a cycle of the ignition and they come on.
Having googled a few threads on various forums, it seems there are a few common issues
Some key points
Cambelt and water pump done 3 years ago just prior to my ownership at an audi dealer
Water appears to be circulating as heater runs hot and helps cool the engine when sat in the drive so I don't think its water pump related but could be wrong
Fuses on the top of the battery look mint. No corrosion at all however I have replaced.
Turning on a/c brings on the low speed fans
Put in a new fan switch this morning and ran the car up to 90 degrees. Took it for a drive after running it up to temp in the drive with the cap off to vent air
Seemed fine initially but gradually the temp rose again with no sign of the fans coming on when I got home
Pulling fuse 16 in the dash does bring on the fans and aux pump with ignition on
Having switched off for a few minutes, I fired it back up and it sat quite happily at 98 on the drive
I wondering if this is a control module problem. I have seen another thread suggesting a water pump which I guess would make sense although I wouldn't expect my heaters to be blowing so hot if that was the case
Another thread suggested Head Gasket. I really hope it's not that after the investment this year of a new clutch, turbo, bushes etc. The cars never overheated and doesn't get driven hard so I'd be surprised at this but I guess it can happen.
I would be gutted
