Problem starting Citroen C4 2016 blue hdi

[stephenfreeman]

Eureka! I think, Ifound the answer on another site, apparently a little clutch cable clip. The writer had the same symptoms, so most likely. According to the info it is a known issue and was subject to recall, news to us of course, obviously Citroen didn't try very hard to make contact! No surprise there I suppose. I will probably have to remove a bit of the trim to get at it properly, pretty sure I have removed it before so not too difficult. Part is due to arrive from Amazon today. Then the fun will begin, just hope it is as easy to replace as they say it is. I think the link above is for the cruise control, I have one of those on order just in case but I don't think that is the problem.

Thanks, I'd already found that, ours looks a little different but I have one on order. Possibly more likely is the clutch cable clip which sits somewhere on/in the pedal assembly itself. Anyway I have removed the trim ready. The clip should arrive today, the switch may be something of a slight wait.

It could be the switch, though it is supposed to be for the cruise control, which we don't use, I had a fiddle with it and the car did start with a firm deression of the clutch pedal etc. The actual piston for the clutch cylinder appears to work satisfactorily, I will have another look tomorrow.

Possibly this one: http://c4owners.org/plugins/forum/forum ... php?241152 ?

Could be a cheap fix, I guess that the connector wears and then you don't get sufficient movement of the master cylinder to get the clutch in what the ECU considers the 'start' position. AFAIK the master looks like this, the sensor is integral - with the wiring connector (circled) on the engine bay side.

I think the switch is similar but mounting different, switch is ordered and on its way, I will probably get a local mechanic to do it though but only if its necessary.

The clip is still favourite. I think it is mounted inside the clutch pedal lever (difficult to see) and is supposed to clip over the end of the plastic plunger/piston (again difficult to see). This will most likely mean taking the clutch pedal lever off to do the job, so think it will be a job for a local mechanic. I have a new clip.

Found a very good Youtube video it is in Spanish but has subtitles. In his case it was a Peugeot but very similar and he had to replace the master cylinder as well. I don't think that will be needed though as the piston is clearly not properly connected to the pedal in our case as it doesn't move at first when the pedal is depressed. However it may be worthwhile replacing at the same time.

[stephenfreeman]

I think that the master clutch cylinder might have to come out to access the clip so might be as to have that replaced as well, whilst we are about it. It could also be faulty but from what I see it is not.

If you've got to take it out anyway, seems sensible - they are not massively dear, and you will have done all of the labour!

Hi, just seen another video - not necessary to disturb the clutch master servo, looks straightforward but tricky maybe

[stephenfreeman]

The plot thickens. I have now managed to remove the clutch pedal entirely.
1. The original clip is black and appears to be of a larger size and has an extra locating peg.
2. The clip I have, which is supposed to correct is smaller, it may however fit but have I got the right part?
3. The original clip appears to have worn right through and the ball on the piston rod appears to have worn a round depression in the clutch pedal itself.

I just want to be sure I have the right clip before trying to reassemble it.

The pedal has PA6-GF50 on it.

I shall see if I can find a different clip.

PA6-GF50 is just the type of plastic and not a part number.

Found another lettering on the pedal VIC 1 >SEBSK 9678478080 01

Looking on Ebay there appears to a type of clip similar to that fitted, which is different to the one I have.

[stephenfreeman]

I have attached photos. There is only a little wear on the piston ball. As you can see the ball has worn right through the clip and has impacted on the clutch pedal itself.

Correct clip now to hand, just waiting for the weather to get a little better first. For those interest the Citroen part No is 98 204 202 80

[stephenfreeman]

Mobile again ! The hardest part was putting it back together again, especially the last bit, a small mirror helped to get the bolt through the hole. If anybody needs to know, Amazon sell a type of pincer designed to pinch the ears of the old clip together (BGS 8968 | Piston Rod Removing Pliers | for Clutch Master Cylinder ), which makes removal easy, it cost £20.55. So plus the clip about £50.00 altogether. Though of course I had all the other tools needed already, which apart from the special screw tips also included a G clamp. The clutch works perfectly now and the car starts first time.

Great result, well done!!
