Hi Guys

I'm having an issue with my 2018 Citroen Relay, in regards to the DPF.

It all started a month or so ago where the vehicle went into limp mode and the engine management light came on the dashboard. The service was due anyway and went into the dealership for a service and to diagnose the fault, the vehicle was in for 4 days as they were struggling to find the fault, I had a call from the dealership claiming the fault was due to the a software update.

Fast forward to now, the van is back in limp mode and is currently at the Citroen dealership, however they are claiming it is not covered under warranty.

The van was purchased used last August from Citroen with 8,000 miles on the clock, it now has 24,000.

I'm a bit stuck and do not know where to go from here! Just looking for some advice.

Many thanks.

Why is it not under warranty?

OP, not sure whether this will help or not.

I own a Ford S-Max with the PSA 2.2 Diesel lump. My usual mileage (pre-lockdown!) was only 4-8 miles / day, all in town albeit not necessarily stuck in traffic. I'd had many problems with it going into limp mode, emissions etc.

Mine turned out to be the emissions equipment Ford saw fit to install in order to get the engine to Euro V compliance. There's a pre-heat device (I think another glowplug) just ahead of the DPF and a balance pipe that regulates emissions pre- and post-DPF: both of these had failed on my car meaning it couldn't clear its DPF the way it has to when it can't get it up to temperature for long enough (ie when driving in town). Once those were replaced, it ran fine and continues to do so. Parts were ordered (by me) off eBay and the whole job cost c£400 IIRC.

I would expect your vehicle to be covered under warranty, and I'm not suggesting the above is the definitive diagnosis, but it may provide inspiration.

Either way, good luck - hope it works out!

Because the vehicle hasn't done enough mileage apparently!

What do they mean by that? Enough mileage for what, the DPF to regenerate? Is this what the issue is?

I believe so, they have told me it needs a re-gen but I need to stump up the cost.

We no longer run PSA in our van fleet but most DPF’s can be force regenerated If the warning light comes on.

From past experience we had issues with the injector that heats the DPF failing but this was always covered under warranty.

I would put all correspondence in writing as I expect there is an underlying issue that a regeneration will only mask.

On the relay and boxer vans it'll be the exhaust catalyst fuel vapour valve at fault. This basically injects fuel into a canister pre dpf to keep exhaust temps up. It'll show up on a code reader as a dpf fault but it's actually nothing to do with the dpf..

That will be this,

It does usually leave a fault code though. However anything can cause issues, the older fords would not regen if the fuel level was low, mazdas don't if the oil quality light isn't.JLR have issues with Adblue as do Mercs.

That's the one. Will go into limp mode if at fault.

I'm sure Ford sell the glow plug on its own but it welds itself in and its impossible to remove.

Citroens are great cars. Problem is the dealers are ste.

A 2018 vehicle with 24K miles is above average mileage.

Have they showed you the T&Cs of the warranty that relate to having not covered enough miles? Regardless of this they can easily do a regen themselves

As with the boxer/relay vans, sometimes it's the whole canister which needs replacing circa £300 iirc..

I’ve had an update from the dealership. Any advice in regards to the below?!

They will re-gen under warranty but I have to pay £240 for the additive fluid to be filled.

Some of the PSA engines run Adblue and a ELOYS fluid, if its the pouch then they can be stupidly expensive. If it is just the Adblue then its cheap enough aftermarket (if it was a jlr car then i'd say buy genuine as it creates issues when the injector melts) However if they are charging £240 to carry out a forced regen then i'd take it back, top the adblue up myself and stick it in 5th and get the revs up and give it a 30 minute run. There should not be any need to force a regen then should automatically happen

It’s not the Adblue, I keep that topped up myself. From doing some research it’s the Eolys fluid that needs to be topped up, would £240 be reasonable for this?

Its not unreasonable, I diy'd the wife's Peugeot for £90 (I have lexia so could reset the fluid level in the ECU) so £240 at a dealer is probably about right.

Edited to add eolys at 24k miles? It was 90k before our car needed it.

Eloys is usually check around 62500 i think. Some can be topped up and its around £35 per litre, some need a pouch and it is around £170 plus fitting - 15/30 mins, so no £240 would not be unreasonable.

I guess I should be questioning Citroen why the eolys needs to be replaced so soon at 24k.

I’ll check the manual tomorrow to see if it has a replacement/refill schedule.

Hi...

Having an Issue with my 2018 Citroen Relay 2.0 HDI, its been in and out of the dealers for the year that I have had it, 2 injectors changed, Starter motor and clutch switch, now I have another engine management light on and a warning of CHECK AD BLU SYSTEM

And its now just out of warranty

Friend pulled a fault code out of U059E (nox censor) but the dealers came back with a fault code of P2402F97 (and £99 later) (DPF issue), they have said it needed a regen (£99 later) that didnt work, now they are saying it needs a new DPF, they refuse to give me the print out or a copy of it and have not mentioned anything about the CHECK AD BLU WARNING.

Van has done 102,000 miles, 90% motorway miles.

Apparently they have put a claim into Citreon and they have rejected it
