would be good if you could monitor the temp that the ECU is seeing whilst the gauge it going up and down
I agree with Steve B these are classic thermostat failure symptoms, but the last few weeks have been very cold outside temps and asa result my TDI as not got past 70 Deg C on the gauge on my commute to/from work which is 7.5 miles on all B roads.
When it is very cold outside and the cabin heater is on full, unless the engine is above around 2000 RPM it simply does not generate enough waist heat to heat up the cabin, hence the temp falls away.
The Webasto helps greatly, but at the expense of burning extra diesel
All I am saying is that it may not be the thermostat, but simply slow driving and cold ambient temps
My own A2 will hit 90Deg on the gauge after about 4 miles of motorway running at 70MPH, but then pull off the motorway and drive through towns etc without the webesto off and it will drop on the gauge quite quickly when it is only 1 or 2 deg outside
