Strange sound!

[DS3 POWER]

Yesterday after a 90 km trip I started my engine and it seems to make a rough grrr sound (if that makes any sense) after 2000rpm..no engine check light on..could it be the belts or engine mounts?

Notice you have the HDi, It could be a DPF re-gen taking place ?

When mine is doing a DPF regen it sounds a bit like a hovercraft or a large fan (the car fan runs a lot faster) and the stop start is deactivated whilst the process completes. Is that the sound you're hearing ?

[DS3 POWER]

its a 1,4 engine but it only has 12500km on the clock so i dont think that the dpf is regenerating..yes,hovercraft could be a way of describing the sound..

[lfcrule1972]

I think the regen's happen from new mate, I certainly recall both mine doing it within a few months of picking them up from the dealers, they may have done it before and I didn't notice if I was driving along

DPF Regens happen every 500-800 miles so every 800-1300 KM...

I think you have your answer

[DS3 POWER]

Yeah but how come its the only time that I hear this sound?I should have heard lots of times before right?

[lfcrule1972]

Nope, based on Zacks mileage figures above some may have occured when you're driving on motorways or noisey roads, I think in the two years I've had a DS3 I've heard it maybe 5 times or so and that's over 36,000 miles ! So it's done the regen a lot of times

Most of the time the diesel regen will be happening at speed and the background road roar would drown this out.

wtfffffff now i have 12500km and a warning came on to take it to citroen at 13500km for service..my book says take it to citroen at 15000km..dafuq im trippin

[lfcrule1972]

My diesel DS3 needs to be serviced at 12250 miles I think.... I would've expected the interval to be higher in KMs myself

[Bigfeet]

The indicator is designed to come on early to forewarn you about the impending service.
