Hi everyone,
Vehicle is a 2010 JSW TDI (CJAA). I noticed recently after doing an oil change and DSG flush (but also intermittently before) that my engine fan is running a lot on high speed. I noticed that while driving, specifically when making a stop at a red light, that the engine fan runs a lot and at high speed. When I turn off the engine the engine fan usually keeps running for a few seconds, not nearly long enough for it to be a regen symptom (also the idle rpms don't suggest that). This happens pretty much every time I drive it, usually after shorter trips but also after longer and faster ones. My AC hasn't been on in weeks, temperatures in the 50s-70s here in CO.
The coolant temperature gauge in the instrument cluster sticks at 190 or below, it never goes above 190. It does take awhile to get there though, especially when it's colder out, and when at 190 and going downhill for a mile or so with little to no throttle, the gauge drops slowly, which would be consistent with TDI behavior and does not make me think I'm dealing with a faulty CTS here. I also hooked up my VCDS after a 20ish mile drive yesterday and went into the engine module and the coolant temperature was at 83C -- the engine had been off for less than a minute at that point.
I tried the AC troubleshoot for the fans - turned on ignition, set fan to 1 and turned on the AC. Light comes on, fan is running but neither one of the two fans in the engine bay turns on. VCDS output test for coolant fans seems to be working properly though, both fans turn on when running the test and go back and forth between low and high speeds until test is stopped.
Lastly, requested regens in VCDS shows 2.0 (was 5.0 on the weekend), completed 0.0, mileage / consumption and time since last regen all blank.
Could it really be that my vehicle is running regens this often and for some reason they never finish? Or am I looking at a faulty AC-related switch here? The AC does work though!
Apologies for the novel, planning a road trip for next week and don't want to just ignore this.
Thank you so much guys!
