Caddy Maxi Electric fan.
I am trying to find out if its normal for the electric fan to be running when I pull up after a journey, I would have thought it would come on after a few minutes of ticking over.
I have driven home about 5 miles along free running roads 40 mph then down to 30 mph when reaching my village & when I pull up on my drive the fan is going.
Does this seem correct, its not a particularly hot day either.

Re: Caddy Maxi Electric fan.
Short answer is no.
Usually the fan(s) should only stay on when it's been driven hard or it's a particularly hot day.
Even after a long journey mine doesn't stay on after shutting down the engine.

Re: Caddy Maxi Electric fan.
Never drive it hard, the temp shows in the centre of the gauge always. Never seen it above halfway. Could it be a faulty switch or something like that. There are no restrictions on the airflow to radiator & radiator fluid level is always to the line on the expansion bottle when cool, slightly above when hot which is understandable.

@blueboy if its idling slightly faster than normal when you completely stop - around 1000rpm, it could be doing a DPF regen, especially if you never give it a bit of right boot or are doing short journeys?

Defo sounds like it is doing a regen mate, and the coolant temperature gauge on a Caddy very rarely ever goes past 90 degrees, nothing to worry or be concerned about.

Re: Caddy Maxi Electric fan.
Thanks for the helpful information, never though about the regeneration bit. Mostly take the Mrs to work & pick her up in the evening, about 4.5 miles each way.
Gets a run each week to my sisters about 14 miles each way & try to give it a bit of a rev now & again to give it a blast but rarely go past 3500 RPM.

They just pick and choose when they do it, I did a 2 1/2 hour run to wales a couple of weeks ago and it started a regen in the last mile or so of the journey!!!

Re: Caddy Maxi Electric fan.
My 2017 tdi did the same thing when I got home after buying it, then again the day after. Haven't heard the fan running after turning off the car since.
Shouldn't the car indicate in some way if it is regenerating? Does it complete the regeneration if the car is turned off or does it start over the next time the car is started?

Re: Caddy Maxi Electric fan.
Hi i use vag dpf app and vgate icar pro bluetooth 4.0 elm 327 obd 11 car diagnostic scanner to monitor my regens very good you can leave this plugged in and just connect to android phone when you want to see whats happening and when regens are in progress.Since i had mine rolled back its about every 400 miles between regens and i use red x diesel every fill up.I have only covered about 4000 miles since rollback in 12 months but all seems good.

Re: Caddy Maxi Electric fan.
Good idea with the bluetooth OBD reader. Other DPF cars I have heard of tells you when it is regenerating and that you should not turn the car off until it is finished.

Re: Caddy Maxi Electric fan.
It would have been good if VW put an indicator DPF symbol type lamp on the cluster so that you knew it was doing a DPF regen and maybe a bong noise to accompany it in case you did not see the lamp illuminated.

Re: Caddy Maxi Electric fan.
I noticed that the start/stop symbol in the dash was crossed over when the car was regenerating, and the car wouldn't automaticly turn off when stationary. So if you have that function you can tell when its regenerating.
