Just this weekend, once, when I stopped, turned the ignition off, took the key out, locked the doors, the radiator fan remained on.

I waited for a good while but it didn't stop. The only way to stop it was to start the car again. Its a vRS TDi.

Then today it did it again, but this time, when I continued the journey the stop/start didn't cut in.

Anybody had anything similar ??   

It's doing a regen, you have interupted it, it will attempt another next time the engine has started and is up to temperature 

 

Nothing to worry about.

 

Stop/start will not cut in due to the regen

 

Again nothing to worry about

Thanks, but I presume just let the fan run until it stops itself then?

Yes, it will automatically stop itself.

Yep, don't turn the engine back on to stop the fans, leave it, It will sort it's self out

And the point of having a pinned thread is ..........................

It is a bit alarming at first but my car has run the fan at full speed sometimes for up to ten minutes after I have turned the engine off! Dealers and Skoda are maybe not the best at 

explaining what is going on but it is perfectly normal. As for the Stop/ Start system, mine sometimes gives an error message telling me that it isn't working at all and then seems to

work again most of the time afterwards. It just came back from the garage the other week for another issue and the minute I started the engine it gave me that warning message.

Don't have my skoda yet but if its anything like the cars I've driven up to now with start/stop i think maybe what you're seeing is not an error but an informational message...If the charge in the battery drops below a certain level start/stop won't kick in?

The car is only a year old, just over 10,000 miles it's been giving me these messages since it was brand new, so doubt very much if it is the battery that is the issue,

What is the message - if it is Error:Stop/Start System then you have a problem. It is cured by a software update in most cases.

 

Battery management is more complicated on these cars due to the regenerative engine braking performed by the alternator. I.e, when you brake the alternator kicks in to boost charge the battery to assist with engine braking.

 

Under normal driving conditions the alternator runs at the lowest charge it can to power the current load, plus trickle charge the battery.

 

If you are experiencing a regen then Start/Stop will be disabled with a garbled message that it is unavailable as the engine must be running.

A symptom of the times I'm afraid.

Any dealer worth his salt should be emphasising the requirements for maintaining a diesel with DPF on every sale.

Having enjoyed diesels without DPF I am not sure I would want one now with DPF, especially now owning the new generation 1.4tsi

Hmmmmm, dealers must be more competent in Oz than here in Blighty if they know much technical info about the models they are selling LOL..... TBF the dpf issue is much over stated especially if you have a CR, unless you just do short urban trips when they should be avoided. The latest petrol engines are so much more efficient than their predecessors too. Anyway I had 'the fans' when I got home yesterday, so I'll just have to go out for a while to let the dpf do its thing.....lifes a bitch!

I've just got to the thick end of 4k miles on my vRS TDi having had loads of those and had a reminder today that they don't seem to happen any  more - today's 50 min commute increased to 2 hrs due to 'something' no idea what - but it introduced an hour of crawling, stop/starting etc. and the car just carried on. The only time I noticed the 'bump' when it increases fan speed / 10k RPM idle was when I kept my foot a few mm on the clutch rather than just letting it idle in neutral, and immediately dropping clutch 100% stopped it. It did worry me too for the first 2k miles but the engine seems to wear in and all is fine now...

It is the Error/ Stop Start System that I get, did point it out to Henry's this year, said they would look into it but it came back last time from them with that message showing! Stop Start does work most of the time though but it isn't very handy for me to take the car back to the garage but last time they actually collected it from my workplace and then brought it back, might need to give them another call!

Yep, you have a fault, and it will have logged fault codes as well so they have no excuse for not investigating.

 

Take a photo of it next time it happens - I once went over a week without Start/Stop before it eventually got fixed. But that car is someone else's problem now

I think you missed my point, obviously too subtle!

 

The thread is pinned explaining all of this but people still create new threads rather than look at the info that is already there!

Regarding the OP's issue, the stop/start will automatically disable if the car is attempting a regeneration of the DPF.

 

The regen process requires increasing the temeprature inside the DPF to burn off the soot. Turning off the engine mid way through a regen means the car then needs to cool down the DPF as quickly as possible, in case you happen to be parked over dry grass for example, so the fans will stay on until the DPF has reduced in temperature.
