Another vote for stat issues being at the heart of the problem. Out of my seven 2/7/900 series cars, I’ve changed the stat on four of them as they weren’t getting up to full temp. My diesel 940 was totally transformed by a new stat and drives SO much better now. And gets properly toasty with the cabin heater on, too!

A stat is around a tenner and dead simple to change. Slather the stat cap on the car in penetrating fluid as suggested, leave it for a day and spin the nuts off, swap the stat and reassemble. Check torque settings on the nuts when reassembling...I learned this the hard way with my first 940 and snapped a stud by neglecting to use a torque wrench...don’t do that!
