I ask this because occasionally we get issues with Danfoss ORV's Failing and the relevant machine will have higher Oil Temps.
Since Danfoss changed the ORV design several years ago their failure rate has dramatically reduced.
Please keep us informed as yours is a intriguing problem.

Yes, the maag one has the ORV, I've checked this.

The oil coming out of the cold side on the oil cooler is 38c, and the mixed temp is pretty stable on 51-52c

I remember the problems with the older types of ORV, but this one is the new model.

also it ticks me off a little bit that when you order a new ORV insert you have to order the glide strip separately.

Because when the oil has been to hot because of a failed ORV thermostat, the glide strip gets harder and doesn't give an adequate seal around the moving part of the ORV
