Diesel specialist Cork (Citroen C5)

Del007

A light came up on my car today 'risk of particle filter clogging' today and I'm looking for a good mechanic in the Cork region who specialises in Citroen or diesel engines. It's a 1.6 HDI.

Thanks a lot for your help

You need to take it for a good drive at high RPM ASAP. It's the DPF telling you it hasn't been able to sufficiently regenerate. If you don't you could clog it permanently and it's an expensive job.

It could also be a fault with a sensor or a fault stopping it from doing a forced regen but try a good drive first.

Cheers for the reply, what would be considered a high RPM?

Do Dunkettle->Ovens (turn around just before EMC)->Dunkettle at speed limit at around 3500-4000 rpm. You might think you're damaging it, it will be fine.

Go for a long Drive and drive the stones out of it

I think all that's needed for a successful regen is a consistant engine speed, so just a motorway drive at normal speeds in 5th or 6th gear should do it. No need to scald the car.

pah

Few minutes redlining in 4th will sort that **** out

I drove for 40 mins in third gear between 45 to 50 mph but the warning is this there

Cheers for your help

Bring it up to 5000 rpm and hold it there for about 10 minutes (motorway). You might find yourself in 3rd gear doing this in order to keep the RPM high.

Go higher with the RPM if you like, but don't go beyond the red line (6000 rpm on the C5) and don't 'bounce' the speedo off the red line. Slowly and gradually is the way. Also make sure the car is warmed up first and don't start revving the jocks off it after just starting it up.


The warning will eventually disappear. Might take 2-3 goes over 2-3 days to get rid of it but it'll go away.


It could be a sensor, either though.


A forced re-gen on my C5 only cost me about €70 when I got it done with an indy that I know, so shop around (they pretty much wire up the diagnostics, tell the car to force re-gen, and the car sits there revving itself until it's happy). It's the cost of using the diagnostics that's the pricey part with some dealers. To even get a glimpse of a diagnostics machine can cost nearly €100 (thats before they do anything with it... although that's fair enough really, as the machine is expensive and they have to make their money back I suppose). Most indy mechanics will charge about €35 for diagnostics in my experience.



How do you drive the car? is it on the motorway for long spins every day or just pottering about stop-go traffic in a town? If its always on the motorway it's unusual it'd give this warning, and could be a sensor. If it's town driving then the suggestion to get it onto the motorway could well fix it.

That didn't work but thanks for your reply.

I would try it in the morning but I've only gone and lost my only car key whilst out walking a bit ago dam nightmare

Did you get sorted?

Piece of advice, I know this from dpf issues on a 1.6 tdci engine (same engine)

Sometimes the dpf light won't go out or the car will remain in limp mode despite the dpf being unclogged. The ECU registers the dpf fault code as permanent until specialist software is required to clear it.

Tip: With engine off unclip the wire to the airbox and start engine. Run your scan with a basic code reader and as well as the dpf partially blocked code, there will also be 2 additional codes relating to the unclipped wire to the airbox. Turn off engine and clip airbox wire back again. Now erase all codes and all the codes will be erased and car will be out of limp mode.

Erasing only the dpf fault code without having the airbox fault codes won't work for some odd reason.

So i brought the C5 to a local mechanic, luckily he was able to do a forced regen on the car and the warning light no longer remains.

He did say that it could be removed and that would cost about 250 euro.

Has anyone any tips on having a diesel but not doing many miles with it?

Cheers

The best tip is to get rid of it, they just aren't made for short trips.

Not feasible to get a new car at the moment

Every two/three weeks take it on a spirited trip on the motorway - be it M8 or N40/N25. It will heat up and clean the filter.
Remember to use throttle a few times, that allows the variable geometry turbo to work and clean up as well.
