Hi

 

The engine fan on my diesel Superb elegance (2015 registration) has suddenly started continuing to run after the engine is switched off.  This happens when to car has been used on short journeys ( 2 - 5 km)

 

This is the first time  in 55 years of driving that I have experienced this problem and I would be grateful for suggestions as to the likely causes.  In addition would I expect a reading of the vehicle codes to provide any form of diagnosis?

 

Thanks in advance

Probably the DPF was regenerating while the engine was shut off.

 

How long have you owned the car?

 

It's quite normal, but a longer journey should allow the DPF to complete a regeneration.

Thank you for this observation.  I've had many dpf problems in the past but none on this car to date which I bought new.

 

All the recent journeys have been in the 2 - 5 mile region which of course does eventually lead to dpf blockage.

 

Interestingly enough I did have an engine management update about a year ago that among other issues included an update to dpf management to mitigate against dpf blockage due to short journeys.

 

As part of the update, Skoda enhanced the car's warranty to include a 2 year free warranty for dpf issues from the date of the update being installed.

 

Thanks again

That sounds like the dreaded emissions fix (sic)

I appreciate you response.  Could you kindly elaborate what you mean by emissions fix

 

I did not install the original update that VW introduced shortly after the scandal became publicly debated.

 

Last year I did have an engine management system update installed.  Part of this was to do with the ability of the system to improve the rate of engine heating when the car is first started.  The objective is to reduce the time that the dpf  takes to warm up and hence block.  The update did actually come with a free two year warranty for dpf problems.

 

The local privately owned garage that services my car thinks it might be something to do with the rather fancy engine water pump that is probably installed on this engine.

 

Once again thanks for your observations

Volkswagen's Defeat Device Cheat with TDI's until caught in 2015 & then their response, Voluntary Recall and Engine Management Software update & with 1.6 TDI,s a Flow device that ruined some perfectly good cars / vans.  Known as 'The fix'.

There was a 2 year Peace of mind guarantee.   Read T&C that you got when they gave you that in writing & the date. 

 

Any other Engine Management / Software updates with 2 year Warranty Extensions, then again READ the T&C's and if you have an issue and it is valid then you know who to contact, VW / Skoda UK & their Executive Team if a Dealership is not playing the game.

After two quite long runs on the Motorway it appears to be a DPF issue.  Not fully sorted yet but much better
