Vdo oil temp guage accuracy

I installed a vdo oil temp and pressure gauge. Used a proper vdo temp sender.

It's normal operating temp is about 130 degrees C.....266 Fahrenheit. This with ambient temp 15 to 20 degrees C....on the vdo.

Track day yesterday and it was up to 160deg c....320 F.....hot!

We plugged in durametric and when the vdo read 140 or so the dme oil temp from durametric was 105 C.....220F.

Which would you believe?!
Vdo oil temp sender is in cylinder head in my passenger side......your drivers side.

The two senders are in different locations, the VDO in the hotter cylinder head, the factory sensor is in the cooler sump. The are probably both correct, by the sump is more important as it represents the mass of the oil.

I have a VDO vision temp gauge and the sender at the same spot, up to around 200 the gauge agreed with the durametric reading.

Normal operating temp for me is about 190-200 F for street driving. At the track I see 220-230'ish but have never compared with the durametric on track

Yours sounds really high, there are multiple ranges of senders and associated gauges, maybe you have a mismatch?
