Ey Guys ! 

 

well my oil temperature is to low ?  city 70-74  - Highway arround 79-81 (as my OBD2 lcd display said )  is this normal ? or to low ? Thank you

coolant temp is sound ! 90degrees exactly 

I wouldn't take too much notice, those numbers aren't accurate.

Where do they take the figures from?

Is that on the car's gauge?

 

coolant temperature is from car gauge yes!  oil temp gauge just a cheap thing calls goforjump p12

In which case a coolant gauge reading of 90C means that the water jacket (or at least the temperature sensor) is somewhere in the range of 70C to 110C.

The more gauges and the more information you get the more you have to worry about.

 

In 1999, last century, indeed last millennium, I got a new Japanese car, being used to old British cars with often fully mechanical gauges I said to someone how good the car was as once it reached temperature the needle remained rock steady unlike the British cars where the needle (correctly) moved up and down with the efficiencies and inefficiencies of the 'water' cooling system.  Then it was explained to me this was a 'comfort' gauge and not a true range like I was used to.  Ken will have explain as I'll just mess it up but the idea is don't look for exact figures but just what is normally showing for your car running in good condition, or be careful about what you are comparing with what.

True. My Fabia coolant gets to 100°C (per VCDS measuring) before the radiator fan gets going at full speed. The cluster gauge could indeed show those variations in temperature, but it doesn't. It stays glued to the 90°C mark even if actual coolant temperature is 10°C higher (and the gauge is scaled in 10°C steps, mind you).

Also @vonweiser Nta has the right general idea. My point about modern VAG gauges is that, by design, they don't show a "true reading" unless the engine is still cold or is very hot. A couple of my mates' girlfriends ran BL cars with "temperature gauges" back in the early 1980s, and the usual conversation after working on them was "$mate, where does the temperature gauge on your GF's car usually read when it's up to hot?", and the answer could be anything from "just outside cold" to "just short of the red".

Petrol or diesel engine?

Another reason the gauges went from mechanical with numbers to electric with minimal markings, and  other "idiot lights" being deleted from the dash or dials.

Those last 2, and sufficiently unhelpful that normal "hot running" for a specific car could be almost anywhere in the black sector.

So high efficiency, not much waste heat at idle etc. Temperatures are probably as expected at this time of year, unless you're in the southern hemisphere.

If the engine thermostat is the factory-fitted original, it may be worth considering replacement but I'm not sure it would make any difference.  You might be able to clarify what's going on with the coolant temperature using VCDS, or similar to get a number direct from the engine ECU, before the instrument cluster 'sanitises' it.

The actual oil and coolant temperatures will be very similar since there is a heat exchanger that links them together.

PD's generally run cool anyway.

That was the point I think to stop the worry and comparisons of different cars.  The driver would get to know where the needle normally was for that car and if at any time the needle was hotter or colder from its norm.  No comparing of "mine runs at 82c why's yours at 78c" and of course it hides the variations of instrument calibration and variations in how the engines run.

 

A place in Wales make the gauges now and when I emailed them to check the factory test calibration figures for the marks on the gauges I got both were under but as one was further from the normal needle position I was used to seeing it was returned it to the seller.
