I had a scan done today thanks to Dave from B8 forum.
It shows 2 errors which I want to fix asap.
17664/P1256 - Engine Coolant Temperature Circuit (G62): Open / Short to B+
Difficulties with starting a cold engine.
Diesel: an indication is extreme long time burning time of the glow indication light.
Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
RPM at idle is irregular.
With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm.
With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
Bad acceleration during warming up.
Wiring and/or connections faulty
Engine Coolant Temperature Sensor (G62) faulty
Check wiring and connections
Check / Replace Engine Coolant Temperature Sensor (G62)
In MY 1995-2002 (?) in Europe at VW-cars the G2/G62 had the bad reputation of breaking down often. The default G2/G62 is black and all replacements are green.

Any idea if its easy to change coolant sensor? Would prefer to do it myself when I have a spare minute.
Maybe price from stealers ?
With the engine mount solenoid valve am I looking at new engine mount?
