Hi all have noticed on my Audi that the cooling fans on the radiator stay on after ignition is switched off it does turn off after a few minutes but it  never used to happen the engine is reading warm and the water in the reservoir is warm to touch ..... any ideas anyone

Could this be dpf regeneration 

Hello Russ,

When you say warm, does the car still get up to normal operating temperature as quickly as it should, and not exceed normal on the gauge.

We would need to know this before offering meaningful advice. 

Kind regards,

Gareth.

    Hi Russ....welcome to the Forum

    As Gareth has mentioned about the operating temperature, I would ask when it started to happen and did anything affect it (work carried out, etc)

    Also, is the Air Con switched off as this has a seperate fan, so it could be the system finishing off the recirculation and shutting down, etc.

    Cheers  Trevor

    Hi guys and thanks for the welcome .... yeah car reaches normal operating temperature and doesn't boil up sits at 90 degrees and the water in the reservoir isn't hot hot just warm ........ it started when I blew a fuse for the interior light I replaced the fuse went for a small drive about ten miles and could hear the cooling fans running .... the air con is switched off also ..... someone mentioned maybe dpf regeneration bit don't think mine has that function 

    kind regards

    Do you mean the warning check on the dash board  trevor ???

    No, I meant more of a scan on a diagnostic machine (VagCom or similar) which should give you fault codes in the ECU memory of events and components failing, etc.

    You can pick up software and a connection lead on ebay or pop into a VW Audi specialist garage who can scan the car for not a lot of money.
