2015 C4 Picasso reliability

[Citrone]

How are the 2015-16 C4 Picasso diesel models in terms of known issues and reliability?
Found a 2L diesel with 100K miles, would that be considered high mileage?

Thanks

Things to look out for

Not specifically unique to this vehicle:

1) Try and avoid the piloted manual gearboxes. Go for a manual or a fully automatic with torque converter as these will present the least expense and problems that can occur with these systems.
2) For this mileage expect that the particle filter is at two thirds of it's useful service life, so depending on previous driving styles may need replacing or deep cleaning at any time up to 150k miles which is the service life.
3) The DPF additive tank will be due for topping up if not already been done. Please note Eolys DPF Additive is separate to the Adblue (SCR) system and does a different job, so you will have both systems.
4) For this year you will almost certainly have an Adblue tank fitted as part of the NOx depollution system (SCR). These are known to be an issue on may PSA cars of this year. I recommend that you add some adblue cleaner from Wynn's or Forte to the Adblue tank when you next top it up, which can clean the system and prevent crystallisation from occurring.

Electrics, especially the wiring can be an issue in places, but I've not heard of any specific repeated issues on this model and this sort of thing can affect any vehicle.

Thanks very much!

Never had to replace the DPF but understand at this mileage might be the case - what's the cost a full replacement, roughly?

Sitting Comfortably?

Ok so as you mentioned a 2.0L so have based the priced on this engine. Of course, you can purchase these on the aftermarket at various prices and they will be of varying quality, however the official Citroen parts and retail prices are (excluding labour):

Original Brand New DPF, £2218.43
Citroen Exchange DPF, £1721.08.

These can also be cleaned by some places (including Halfords) at varying prices depending on level of clogging. Some can be cleaned in situ - on the vehicle, but obviously results will vary.

That's a bit of a shock! thanks for the info

Yes these are the genuine parts and they have a lifetime of at least 150k miles, so not far of the life of the vehicle to be honest. This is why a lot of people opt for a deep clean which can be done a lot cheaper. But of course results can vary and there are risks that if not careful the internal honeycomb filter can be damaged - especially when using pressure washers. The more professional cleaners will remove it and use a 'bath' and appropriate chemicals to do the job which is less harsh.

These are typical OEM prices though and are similar to most modern diesels.

So consider getting a lower mileage one if you can. Also, do have a look at the Citroen approved used vehicles website as they have a choice of vehicles nationally and of course have a Citroen approved warranty with them.

It's called Spotify and is the name for Citroen used vehicles, link here. You just pop in 'Picasso' and any other options to filter.
