Hi guys, you've been most helpful in the past but I am at my wit's end and wonder if you can assist me with a final stab at fixing my 307CC before scrapping her. I've been to an alleged "Peugeot specialist" and fobbed off with guff advice, and am now clutching at straws. My MOT is due up in a month and I need to decide whether or not to fix my car, or just abandon her.

Situation is as follows:

July 2015 - Bought from a colleague, ran well, very pleased.

November 2015 - "Anti Pollution Fault" (APF), subsequently diagnosed as EGR valve failure. EGR valve replaced by Griffin Mill Pontypridd, "Peugeot Specialist". Cost, £800 parts and labour. APF still displaying after replaced EGR valve.

December 2015 - Griffin Mill advised that APF was still displaying because the turbo had been damaged when the EGR failed (I had to drive it home from where I was). Offered me 3 options - after market turbo, reconditioned Peugeot turbo or a new one. They advised that "there are sometimes issues with after market parts, we advise you buy Peugeot". I chose the after market option as cheapest. £1,100 parts and labour.

December 2015 - After paying for the fix, the fault repeated 24 hours later. Griffin Mill offered a RMA replacement, but weren't able to install until January.

January 2016 - Replacement turbo installed. Ran ok.

April 2016 - New flywheel and clutch installed. 12 hrs after picking up, APF returns. diagnostic tool reports the following P codes (which I have attempted to track down on the internet, in brackets):
P1351 - ignition coil circuit high voltage?
P2563 - waste gate solenoid valve fault?
P0299 - turbo pressure too low?
P2565 - turbo voltage above maximum threshold?
Griffin Mill told me "we advised you there were issues with after market turbos". They offered another RMA, which I accepted.

May 2015 - Dropped in for turbo fix, to be told "actually it's just the valve, come back in 2 weeks".

May 2015 - 2 weeks later, dropped in car to have valve fixed, APF still showing, P codes as previous. Griffin Mill now insisting on a full replacement of turbo, pipes and fittings, at £1,400.

The situation now is that I have a car with an APF light which I expect to fail MOT in early July. I can't justify spending £1,400 on a replacement turbo system on a car that's worth £2,000. However, I have done some reading around and have the following questions:

1 - Having read around a bit, it appears the ECU will tell the turbo not to work if it senses other problems, which is why APF is so common. Is it possible that the P1351 fault is triggering all the others?
2 - Could all the above faults be the consequence of grotty air lines for the turbo (which I could probably get fixed by a mate who knows his way around cars)?
3 - Could a blockage further down the system, i.e. CAT, cause these faults to occur?
4 - Am I being ridiculously overpriced for the work needed?
5 - Has anyone had a similar experience?

Grateful for any advice, I need a solution within the next 2 weeks really. thanks in advance guys.

P1351 is the relay controlling the glow plugs.

You've got a wastegate solenoid issue, turbo underboost and a turbo boost control position sensor fault.

I'd ignore the P1351 glow plug fault code for now.

Constipate on the turbo issues. I'd start off by looking at each vacuum solenoid valve individually - check wiring and the vacuum pipes, make sure everything is connected and snug. Trace the vac pipes to each component and check for splits. Then inspect check each component.

If you're uncertain, a garage can do a vacuum test for a relatively small fee.

With regards to the blockages, it is possible for the cat and/or DPF to cause turbo issues. Giving them a clean should clear any build up.

Then clean out all the supply to and from the turbo.

Looking at the fault codes, there's a strong suggestion that the bits controlling the turbo are at fault, not the turbo itself.

You may even want to look into the EGR again - it's all supplied by the same vacuum system.

If the repair/replacement on the EGR was flawed, it could have interfered with the turbo.

I was looking at another member's 307CC and he had a valve MISSING :eek::eek::eek:

There were two open ends of vacuum piping, with no component near by. He had a lack of power, no turbo boost at all. He then connected the two ends (in theory, bypassing the valve which ought to have been there), hey presto, he had a turbo again.

Finally, if you can get the CC on Peugeot Planet, it'll give you live data and variables readings, this may open things up a bit more for you.

I would NOT ignore the glow plug fault code as it may well be 1 off the reasons for all the issues you have been ripped off by someone who reads faults and throws parts at problems.
your problem is most likely DPF related ANY fault that can potentially cause pollution will put an anti pollution display on.

EGR is NOT vacuum on these its electronic advice above is all based on 2 litre 8 valve engine yours is most likely 16 valve with a DPF.


Its an HDI not TDI

Many thanks all - though I have a follow up question, or three rather.

1- I suspect the dpf fluid tank under the car is empty. Could this be a contributing factor?

2- Is it possible to clean the dpf fairly straightforwardly?

3- do the glow plugs need to be working to recharge the dpf?

Many thanks again

1 - if someone near you have peugeot planet,they'll be able to run a test to see how much fluid is left in the tank.

2 - Yes the DFP is relatively easy to extract and clean...i just flooded it with water then upended it over and over till the water ran clean, then gave it a tap and went over it again.
i wonder if it's prudent to clear out the cat too, i wish i'd have done that when i done the DPF..if only to ensure the least restriction in flow.

3 - Yes again! this is quite annoying as i understand it can be a pig to remove them.

System needs 3 good glowplugs to function they do not affect starting so you will not know if they are faulty.

Empty fluid needs refilled no fluid no regen

You need someone who understands the system to go through all the various parts looking at issues NOT just reading fault codes and throwing parts at it fix the obvious issues and the DPF system can actually work fine.
