Cooling fan continues after engine stops

[MikeWeare]

The cooling fan on my 2017 t6 carrys on after turning off the ignition even though it is at normal temperature. Is there a fault with the fan temperature sensor ?

That’s normal when the dpf hasn’t completed a regen

As @Pauly says, but can sometimes mean there is an issue elsewhere too.

I'd get it code read just to see if there are any underlying issues.

Is it doing it every time you switch off?

Thanks for the reply … no not every time

Did a re gen 2 weeks ago, haven’t noticed if it’s done it since but will keep an eye on it… wasn’t aware they’re linked

You can tell when it’s regenning the tick over is around 1000 rpm whereas normal is 800 … leave engine on if you can

 

[MikeWeare]

That’s good to know. Thanks

My T6 dsg has just hit 120k and I think there is movement somewhere in the drive train noticeably when starting the engine. I know it’s a long shot but what could it most likely be … engine mounts, drive shafts, gear box. I want to get it checked at the next service.

I had this on my T5 and it went away when I changed lol the mountings

 

[MikeWeare]

Yeah, I’ve seen a few posts on this … thanks

The rubber in the front engine mount can split, which could give an amount of play when starting the engine.

 

[MikeWeare]

Ok, I’ll get it checked. Thanks

Regen happens every 200 miles, is that correct @Pauly ?

 

[Dellmassive]

Regens happen automatically when needed according to the soot level.

Regular as clockwork on mine at around 1/3 and 2/3 fuel tank mark...so are around 150mile intevals, but it changes with driving conditions.
