It took me ages to suss it out, and in my case a change of thermostat eventually rectified the issue.

Suggestion

The car was over cooling and because it didn't warm up in the expected manner/time frame the monitoring system uses the temp gauge and light to alert you.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Ive got a cayman s 2007, while driving today, only 5 mins into the drive the temp gauge went to zero, and the red bar at the top lit up red, for overheating i take it, then the gauge started working again with in secs, back to normal 80 temp and red overheating light went out, when i stopped a few mins later, the car did have that hot smell about it

POST 2Original post

After the engine cools down check the coolant level. If the level is low top up with distilled water and get the car to a shop to have the cooling system leak found and fixed. Bear in mind it might be due to a leaking cap. If the coolant level is ok the problem might be due to an intermittently failing coolant temperature sensor. Or it might be due to a loose connection. (My Boxster had (still has AFAIK) a marginal coolant sensor connector. How I know this I need not cover right now, it is a long and involved story. While the gage or warning lights have never reacted like you described, the actual temperature readings (logged) have upon occasion spiked under some specific conditions: hard turn on rough pavement.) My point is do not dismiss a bad connection/connector.

POST 3 / ORIGINAL POSTEROriginal post

ok cheers mate, going to have it checked over, coolant level seems fine, iam thinking temp sensor or wire problem

Hi there, I got the durametric ecu reader, found temp sensor fault, so replaced that, had to delete the fault codes and all working again cheers for your help
