Hi all

I have a new blackline and a couple of times over the last few days I've got out of my and heard the fans operating very loudly for a while after I've stopped. Any ideas if this is normal???

That does sound like you stopped part way through a regen.

Totally normal. It's to cool the exhaust system after a passive regeneration. Look forward to a flat battery everytime you start it in a couple of years.

I'm looking at new batteries now as I don't trust mine after its been sat a day.

Other half's bora been sat for 7 days under the snow and starts after half a turn.

Thanks guys. Never thought about the battery issue

Agree with what other posters have said re fans running full blast. My Blackline has done this a number of times after short runs in cold outside temperatures. Mentioned it in passing to the Skoda dealer this morning who said it is totally normal.

Trundle nut is spot on- you've switched your BL off part waythrough a passive regen. Like BA I asked my dealer about this when exactly the same thing happened to me before Christmas. Apparently if you switch it off part way through it won't restart the cycle and waits until the soot you've just burnt off is topped up with new stuff, which is why it happened to you again not long after.

The signs that it's doing a partial regen can be difficult to spot (especially if you've got the stereo turned up tad) as you'll get no lights on the dashboard, but you will get some or all of the following

1 an increase in tickover from normal 850 to somewhere between 900 and 1100 RPM

2 Difficulty in driving it in slow traffic, due to above

3 A possible change in engine note

4 Possible 'hot' smell as the DPF is heated up.

My dealer recommended that IF posible when it's started a partial regen that you carry on until it's finished- the tick over will go back to normal when it has, but you have to recognise it's doing it's stuff before you switch the engine off as if you do it'll abandon the regen.

The action you should take is just drive it normally- you don't have to go through the same rigmarole as with the PD engine

The latest advice on DPFs is on Skoda's website.

Nothing to worry about providing you don't keep abandoning the regens. I had mine regen the next time I went on a reasonable trip and haven't noticed it do it since.

The procedures for keeping the DPF clear and self-initiating an active regen is the same for both CR and PD.

Skoda have issued seperate DPF guidance for the 2 types of engines. For CR engines there is no longer the need to maintain a constant speed in 4th or 5th gear while the regen proceedure is active- source of this information is Skoda's website via the link I posted- they produced these updates late last year

Extracts shown below but you'll need to read the full leaflet for each engine

PD engines

What should I do if the DPF

warning light comes on?

This light could illuminate between 10

and 1,000 miles. When the light shown illuminates,

it does not mean there is a fault on the vehicle.

It means the vehicle needs help to carry out DPF

regeneration. The procedure involves the vehicle

being driven in a certain way to help increase the

exhaust temperature. Drive continuously for about

10-15 minutes at a speed of at least 40 mph in

fourth or fifth gear (automatic gearboxes select

Sport mode), to maintain an engine speed no

less than 2,000 rpm. Higher engine speeds are

perfectly acceptable where conditions allow.

If the conditions described are not met and the

DPF warning light does not switch off, the level

of soot in the DPF will continue to increase.

This will increase to a certain level, where two

warning lights will appear together.

Other half's bora been sat for 7 days under the snow and starts after half a turn.

Got into mine today for first time in over 3 weeks and started instantly. I was semi worried, what a relief.

Have you got the 61 ah one or something more suitable!

I guess the point I was making is it isn't a rigmarole, a constant speed and rpm is required to allow the DPF to regen on both engines, which takes between 10 and 15 minutes, albeit at a higher rpm on the PD.

Coming to a stop in either the PD or CR will interupt the regen, hence the active fans.
