They're there to be used.
But if you can afford to store and buy another to use ......
I've got 6 nice A2's so I can quite easily tuck this one away

Nice one, in that case she's a saver.I've got 6 nice A2's so I can quite easily tuck this one away
Check the 12 volts supply to the FCM. The fan draws quite high current, so any high resistance connection will reduce the voltage dramatically.Diagnosed a slow rotating radiator fan.
Did the climate output test, no difference in fan rpms between speed 1 and 2.
Measured signals on the 6pin connector, 3 pins populated, 1: alternator charging signal - ok, 3 / 5: ground from the climate control module (speed 1 / 2) - ok.
Connected the fan directly to 12v and it rotated full speed.
Bye bye radiator fan control module
Are you're talking about the Cobalt TDI that I used to own? If so, I'm glad to see it receiving plenty of attention and new parts. It always revved very freely, I suspected the EGR had been machined out, did that turn out not to actually be the case? I'm surprised it needed a thermostat though. I had that done at WOM in 2019 so it would have been OEM or at least equivalent quality. Should you only expect them to last 4 or 5 years these days?Today on my wife's Tdi I:
Started at 7 last night and finished at 2 this morning! Now off to do a day's work...
- Replaced the tandem pump and gasket
- Removed the EGR, cleaned it up and put back with new gaskets
- Replaced the rocker cover with the later type and reinstalled with new bolts and gasket
- Did the oil and filter, and replaced the air filter
- Replaced the thermostat and put in new coolant
- Found the cause of the ticking sound under load - as I suspected, inner CV joint has gone thanks to a separated boot, will do this once I have the parts
With the amount of posts about the TDI thermostat it should have its own forum!!!!Are you're talking about the Cobalt TDI that I used to own?

I ask because I'm not completely sure about the 'stat on my Crystal TDI, that I last had done in 2018. Although the temp gauge stays at 90 once it gets there, to get there in the first place it can take 10 miles even with the Webasto going - and the last 5 of those miles at 60mph. It's now getting to that time of year when the mornings are no longer quite cold enough to bring the Webasto in, and on those days it can take 15 miles to get fully warm. If the last mile of that wasn't a 50mph incline, I'm sure it would take longer.
Those of us running CDIS can do this without plugging VCDS in - I have a journey later from parents' in Maidenhead to Epping in Essex so I will do this and report back- I may do 5, 10, then 15 minutes. I know my thermostat is working correctly and this journey is 3-4 miles back roads and then all motorway - and all on the flat; unlike when I'm home where I have to ascend a steep hill only a couple of hundred yards from my house - so it will be a good baseline.With the amount of posts about the TDI thermostat it should have its own forum!!!!
A suggestion for TDI owners. It seems clear to me there should be some definitive data for coolant warmup. If several TDI owners with healthy thermostats logged with VCDS say the first 20 minutes at say 0β, 10β & 20β over the seasons, with brief description of the journey, then the logs can be can summarised by a simple graphs with Excel. With a few graphs posted in various scenarios a definitive bank of results can be made, ready for comparison by the TDI owner who is questioning their own thermostats.
