2013 C3 Picasso diagnostic advice

Post by mwclarkson »

Many thanks for taking the time to look.

I've had my beloved 2013 C3 Picasso 1.6 Diesel (90PS I think) since 2015 and have covered 75k miles in those 6 years, taking me to 103k just now.

Never missed a service and had nothing other than the odd bit of suspension parts (track rod end, CV boot, etc.).

Yesterday I get an orange service light suddenly and the car loses power (still runs, but turbo disabled? top speed of about 55mph and no oomph).

I plugged in a little OBD2 I had lying around and get no codes found.

I clear the memory and it comes back straight away.

I left the car for a few hours and the service error had cleared, but I had an orange check engine light. Plugged the OBD pack in and get P0003 (fuel volume regulator control circuit low) and a P0245 (turbocharger wastegate solenoid A low).

This morning I drive the car to the garage (local indy place I've used for years for routine mechanical stuff) and there are no codes, no lights and the car drives well.

I get a phone call from them to tell me the additive injected into the particulate filter has exceeded the maximum threshold - they quote me £1500 replace the DPF and the cat filter, most of which is parts.

I'm surprised, because the car gets plenty of long runs - admittedly a 20-minute each-way commute daily, but at least monthly runs over 50 miles with 3hr+ runs at least bi-monthly. We've never had a DPF specific light (or, indeed, any error lights in 6 years!)

They've given me a printout of the scan and I have the following codes:

9HP - BOSCH EDC17C10 - 1.6l
P1445: Quantity of additive injected into particle filter has exceeded maximum threshold. The particle filter must be changed.
P0245: Fixed geometry turbo control
P2426: Control of the bypass of the EGR echanger
P0003: Fuel flow regulator
P0493: Twin speed fan: Incoherence between the setting (no command) and the status of the cooling fan

EOBD
P0003: Fuel volume regulator control circuit low
P0245: Turbocharger wastegate solenoid A low

If the DPF is done and it's a big bill then I'm likely to get rid of the car for whatever I can get. It's worth maybe £2.5k fully working, tops. I'm expecting to get less than £500 for trade-in now.

Is it possible the garage has jumped the gun? They're absolutely great for mechanical stuff but I wonder if they've taken the error codes at face value and actually there may be something else going on that could be an easier (and cheaper!) fix. I'm probably clutching at straws, I know...

Note: Assume I have no tools or mechanical experience. I mean, I have spanners and I can change a wheel and a battery, but I'm not at all confident finding a solenoid, never mind testing it.

The particle filter can be cleaned (even Halfords provide this service now), but the other issues do need addressing to rule out possibilities of related errors.

On the DV6TED4 110 BHP the filter should be checked at 112k miles.
On the older 92 BHP DV6DTED the filter should be checked for clogging at 100k miles and thereafter every 12.5k miles

So it is coming up for about that time where it should be serviced (cleaned or replaced).

Thanks, does £1500 sound an appropriate figure? The garage seemed to want to replace rather than clean it.

To get it cleaned out you & the eolys refilled you would be looking at at least half that figure. Being a DV6 engine the DPF can be split from the cat & given a proper clean off the car. Try & find a garage that uses the Tunap cleaning system.

Agreed - they are much cheaper than that if replacing in any case - of course quality and the type of components they use to make the filter will make a difference to the price, but still plenty of alternatives.

Thanks all.

I'm about 95% certain I'm going to throw it in as part ex on something newer.

I have to admit I'm quite disappointed - I always thought that with plenty of long runs to look after the DPF and regular servicing on the nose I should be able to get well past 100k before a huge bill.

It's definitely put me off buying another diesel.

It's swings and roundabouts - DPF and other emissions equipment is the price to pay for clean air, better MPG and for at 103k miles is not bad for a DPF life, although some do get much more out of them. But looks like you have some other issues presenting that may or may not be contributing to the fault.

Some of the newer petrol engines are also good, but they can have their own set on unique problems too - especially the newer models, so good luck with whatever you decide.

It's unlikely the DPF is causing the limp mode - it will be either the one about the fuel pressure or the turbo. When was the fuel filter last changed?
