New genuine thermostat. It’s labelled as 88degrees but the OBD 2 is indicating that it sticks at 90 degrees. Not worried just weird. Did a 70-90% change on the coolant too and I replaced it with the same type of stuff that came out.

So nice having the car running at operating temp again oppose to 61-64 degrees that it was at!

Also did 3 out 4 of my duff glow plugs. 3 came out very easily and then one was not budging so I’ve left it! I don’t have a DPF ,live where it never really gets down to freezing and it’s got the AUX coolant heater as well so the engine doesn’t stay too cold for long!


Also I stuck my EGR valve into my Ultrasonic cleaner for half an hour even though it wasn’t too bad (I think it may be new as it’s labelled with Pirberg Brand oppose to the BMW markings) but always worth giving it a boogie while I had the manifold off

Out of interest does the 3.0d have a glow plug light? Or some kind of display that it’s using the plugs?

Just noted a couple of old looking vacuum lines that need replacing at some point...... but I’m going to enjoy the fact that im fault code free (save that one bloody glow plug) and all fluids and filters, other than the transmission have now been changed.
