Oil Temperature gauge issue

Hi,

I'm looking for advice regarding the oil temperature gauge.

I've got a 997.2 Turbo and the oil temperature gauge seems to have a mind of its own.
20mins on a motorway at 70-80mph oil temp rises to 90 I then come off the motorway and drive in traffic at much slower speeds and the oil temp goes back down to 60. Shouldn't the oil temp stay constant once it's warmed up (90) ?

Thanks in advance
Mark
 
Hi Mark
I don't have a Turbo (yet) but with my 997.1 4S the temperature gets up to 90 after initial warm-up. On the motorway and A roads it sits at 90. I have been driving in London traffic recently (not recommended) and I have noticed the temperature goes up to mid/high 90s with all the stop/start, but quickly drops back to 90 when normal driving resumes.
Hopefully another Turbo owner will throw some light on it.

Thanks for your reply Chris
 
Mine stays pretty much constant between 80 and 90 and certainly doesn't drop back to 60. I seem to recall it runs cooler when in sport mode ( or is it the other way round!) but still not below 80. I guess there could be a thermostat issue?
 
Yeah - I'm kinda thinking I've got a thermostat issue

My outside temperature gauge as a mind of its own too !
 
Hi Mark

My car had a similar problem a month ago except that when it got cold it stayed cold and dragged the water temperature down 10 degrees as well.


There was no fault stored, the OPC diagnosis was the oil thermostat as the car had suffered a sticking vacuum valve a year ago, this fault was stored in the car.


The thermostat has been replaced and all is well, coolant steady at 80 and oil steady at 90.


My car is PDK and has covered 35000 miles.


Hope this helps.
 
Brian,

Thanks for the response and details - I've booked my car into my OPC hopefully I'll get this sorted shortly.

Regards
Mark
 
No trouble Mark

Thinking back, your car’s symptoms sound more akin to mine when it had a sticking vacuum valve. I would suggest it’s worth asking the OPC to plug into the computer, that was how the valve issue was identified. Might even be worth doing the oil stat while they have the car.
