Cooling Fan on continuously 2015 Custom

[DCL]

My cooling fan is running continuously. Air con is not on, or set to demist, and I've checked the two high and low speed relays. Any ideas what might be the problem before I take it to the dealer? It probably started when the fan came on normally in standing traffic, but never switch off, and it's now on at start up.

Is van not still under warranty m8

Just to report that this was resolved very quickly under warranty. Apparently the problem was that the 'air con was stuck on'. Whether this was due to a mechanical, electrical, or software, fault I don't know.

i've same problem,i bought van then i move to cyprus. there was no problem with fan. it just started 4 weeks ago no warranty

When the fan starts to work... starting with low fan and then (after 10 minutes) high fan starts to work. when the fan starts to work; mirror and screen heats are working as well. yesterday night outside temp. was 4 degresse but fan was working. what should i do ?

Could that be the dpf being regenerated? Or maybe a faulty temperature sensor?
I would check for codes and maybe live data (temp sensors specially)

i'm living in cyprus(north side) believe me no one can fix that faulty i tried 6 different car repair shop. i'm trying to do it. my english is not very well can you tell me more about DPF ? and i changed already temperature sensor

DPF stands for diesel particulate filter. https://en.m.wikipedia.org/wiki/Diesel_ ... ate_filter

It traps crap from the exhaust to reduce emissions and every now and then it needs cleaning. Every car does it different but basically they all rise the exhaust temperature to burn all the stuff it collected.
Some cars turn on the fan, heaters, etc to increase the load on the alternator and therefore on the engine so they can inject more fuel and rise the exhaust temperature.

I'm not sure if your car has a DPF and/or if it will turn the fan on when regenerating. It was just a thought.

If you connect it to a diagnostics machine you should be able to see the DPF saturation. If it's above 70% it might be trying to regenerate.

But again. I would make sure that ALL sensors (including all temperature sensors) are working correctly.

Hope it helps

Thank you very much,i'll write the result

Hope it helps

we get theese faults

[ozekici1985]

i need DPF,fault is from the DPF. when fan starts to work,i'm driving around 10 minutes 4th gear 4 RPM. 140km/h fan is stops. shortly i need to change this. Thank you very much for help
