Hi Experts,

Just bought a C3. It is VERY slow on the pedal. The seller assured me it was a 92 HP 1,4 HDI 16 V engine and I was presented by a computer info page with a cars vin number. It said 1,4 16V

But am I cheated?

I have a friend with a 1,4 16 v engine I drove a while ago, and it was way faster and you could feel the turbo. But not in my car. My car drives ok and without any noise from engine. Cant feel the turbo or hearing it. No movement of the actuator.

Engine fail codes are: P0402 and P1351 and 0181 After clearing codes and a 10 km drive. This code: P0343

Help a newbie

I've read several post in the forum, but I have no clue about where to start. What do the possible faulty components do, to the turbo. In which order should I test and replace parts?

I've ordered a EGR blinding plate form EBAY after reading other posts. Anyone know where to put it?

Turbo seems all right, but is not making pressure at all, then I drive. How do I test it with the hood up?

What is MAF and how do I test it?

You could well have a failed turbo actuator solenoid. It's quite common.

The solenoid is behind the back of the engine and at the cam belt end.

There are two: One for the EGR and the other is your turbo one.

Don't mix up the pipes or wires.

You could change this solenoid or remove it and test it.

There are pictures and information about the turbo actuator solenoid in this topic (Here)

Many Thanks C3CAR :-)

Wrong?:
I presume it is the 2 objects with the number 70? (yellow color) How do I test them (idle engine bypassing vacuum and 1200 rpm shut off). Which of the to pipes are the one for constant suction of air?

I'll order those 2 on Ebay asap if I can find them.. :oops:

Part can be bought here:

and look for them on ebay here - new parts :)

I got one from GSF this week.

https://www.gsfcarparts.com/184pc0010

The turbo on mine was still spooling when I was pushing past 3K rmp. And coming on hard. I suppose it is possible that the solenoid isn't letting any vacuum through, but it could be equally possible that there is another fault.

I'd check the vacuum pump is making vacuum.

And the actuator is moving correctly.

Many thanks Iceni :-)

I have the vacuum in one of the tubes/hose for sure (where do I put that on the pressure converter valve??? I can see now, that the previous owner have made several mistakes, and the engine room is a bit of a mess, right before selling it to me :cry: ).
But the 'pressure converter valve' (wouldn't have guessed that name) doesn't led the vacuum pass at any engine speed, so it is broken, if I understand it correct. I'm afraid I don't understand the principles enough in the system to bypass the vacuum directly past the pressure converter valve, be course I don't know what would happen. (It must be a fail safe principle I guess.)
If I did I could see if the turbo actuator (guessing again it is the part, where the rod in the turbo is moving) is moving. I will test it manually. I need a vacuum gun.https://www.ebay.co.uk/itm/Hand-Held-Bra ... SwiQ9ZUmXJ
It is a bid hard to understand the mechanical words and translate them correct, with only little know how about new technology in engines. But I'm learning fast. It would have been way better to have an engine fully functional to understand it.
I will make it... With help ;)

The Pressure convertors sit on the back side of the engine.

Remove the air pipes and airbox, then feel down the back of the engine and to the left side.

There are 2. One operates the EGR, The other operates the Turbo actuator.

They use 2 10mm head bolts as fastenings. And have and input and outflow pipe. As well as an electrical connection. I managed to use a small 1/4" ratchet with a universal joint, and extension to get the fastenings loose.

If you have the original pressure convertors they have holes for the fastenings. Meaning both bolts have to be fully removed. The aftermarket ones have slots. So you can put the lower bolt back in a few turns and use it to help locate the top bolt. You should be able to feel if it is a hole or a slot by feeling round the fastenings on the valves.

Other than that I can't help you much, I've only had my car a few weeks so I'm learning the engine myself!

You should also change the filters if you haven't done so already. When you strip the engine you will have all of the correct parts off to be able to do a near full service.

Oil and oil filter. (you will need a 27mm socket for the oil filter cap) It's located under the vacuum pump on the right of the engine.

Air filter can be done when you swap the solenoid as you have to split the air box to remove it. The grey spider in the airbox snaps out, and then the box itself splits in half so it can be removed.

The fuel filter is between the airbox and the vacuum pump, It's a big black box. And you have to prime it once changed.

The MAF is located on the front of the airbox. It will have 3 torx bolts holding it in place. It's a T30 head, and longer keys are pretty useful. I went out and got a semi decent set after seeing how many torx heads are on the engine!

Not cheap but machine mart will at least just swap them if the teeth break off, Lifetime warranty is pretty much essential for torx fittings as they break so easily.

So many thanks Iceni :-)

Cant find the valve and the connection to the turbo..

Pretty sure I have the egr valve controller in front of engine, and not in the correct place.

What is wrong with the turbo and the pictures?

Is it a 16V ?

No, that is an 8v engine.

The air intake pipe is missing, so the air is not being filtered before it reaches the turbo..
