Citroen ds3 sport EML issue

[Doyoulikedags]

Hi guys,

Having a few issues with my citroen ds3 sport and looking for a bit of advice on what my next move should be.

First of all the background of the car;
Citroen ds3 dsport thp
1.6 petrol
Manual
99k

So basically the issue is whenever the car idles it hunts a bit and the car vibrates when this happens, strangely though the revs barely move. The EML is on and I get the following faults;
P061F
P0016
P3010
P0033

I have done a full service including new spark plugs and coil packs, its had a new camshaft sensor, new turbo pressure switch but the fault remains. The eml went off for a short period when the cam sensor was fitted, but other than that always comes back instantly when cleared.

Apart from the idle issue it drives really well, not in safe mode, picks up and pulls well.

Mot round the corner so i need to clear the eml to keep it on the road, so any help would be much appreciated.

Thanks

Don't these suffer with horrendous carbon coking in and around the head? Walnut blasting is the cure. Google walnut blasting. You may find a knowledgeable person who can have a look inside the engine and find out if it's this that is causing it.

Blasting walnuts into the engine is just bound to cause further blockages surely..

You blast the head (the intake ports) not the combustion chambers.

I'd check the timing, what are your fuel trims like?

As above, it will likely need a walnut blast decoke by now.

If it has never been done, you have done well for it to take 99k miles for it to become an issue.

Thanks for your response guys, I've looked into the walnut blasting and there is a garage fairly local to me that do it for 250 plus vat which seems pretty reasonable. I will update as and when, cheers.

Agree with the above, as with any direct injection petrol engine the intakes can become carboned up and restricted.

But i don't think you will find that fixes your issue. Id be concentrating on p0016 -cam/crank correlation. You will almost certainly have incorrect engine timing, these engines go through timing chain kits like they do fuel. Id seriously advise getting it checked or checking yourself, its relatively quick and easy and will give you a definite answer.

Same engine as fitted to mini's, timing chain stretch causing running issues. High pressure fuel pumps fail, causing running issues. Coked up valves causing ..... you get the picture .

Gone well for that milage for it to only play up now though.
