Hope all is well with all the ASN members.
To the matter at hand -
The A3 has decided to start overheating recently and i cant figure why?
Drive normally 30 - 40mph it's fine sits at 90oC
Take it up to 40+ and the needle starts going up....to eventually engine temp warning display
I took it out yesterday for 10 minutes and took it up to 50mph and it registered at 120!
Popped the bonnet and it's barely hot
No coolant loss or leaks
Oil level honey colour, all levels fine, no leaks
Can see coolant being pumped around.
After it registers 120oc, i turn off, count to 10, and it goes straight back down to 90oC
Any ideas...im hoping its just oil temp sensor :-)
