Adjust Clutch On Piloted Box With Lexia or Diagbox

[Doo]

Hi all, had a search, but it's "highly" likely I'm asking it wrong

I tried using the laptop to re-set the clutch, but it didn't seem to have the section I needed (truth being, I don't fully understand the options...).

Wife's 2007 C4 (93,000 miles) was playing funny bu99ers and would start, jump forward in gear then stall. It stopped during the summer but came back with a vengeance a few days ago & scared the dinner out of my lad During this cold weather he's been tasked with starting the engine to allow it to warm up before it gets thrashed on the dual carriageway as we moved house. The car started and leapt forward, stopping mm from my bike, which so happened to be outside the garage while it gets spruced up (the garage).

So, it's looking like the clutch (original) is worn past some set point and now needs to be manually adjusted by the laptop as opposed to the on board system.

I also still have to programme a new key & fob, but again, my ineptitude prevented it. I watched video's kindly supplied, but my lexia (or DB) doesn't appear to have certain parameters!!! Or more likely, I am missing cells

Can someone provide a link for the former and possibly explain the latter because my ears are getting bent all out of shape

On a positive note, my 2012 Lingo with same set up is performing beautifully at a kick on the @rse off 150,000

Thanks all

i used diagbox as lexia wouldnt work properly on my 07 c4 picasso,
the sequence to get to clutch reset and then gearbox setting parameters is to select these
Repair
Gearbox
Pack reparation
Replacement parts
Gearbox programming
if you havnt already i would check the hydraulic fluid level in the egs resevoir

Bear in mind that the hydraulic fluid levels on this system are always checked with the hydraulic circuit depressurised using the diagnostic tool.

Thank you for this info. I believe this is where I am going wrong

I didn't realise "repair" was the door I was supposed to open I'm used to different diag tools (some old, some new), but I'm guessing the French have a different approach...

Her indoors (currently out of doors at work) will be delighted at the prospect of having a car that does as it's told as opposed to as it want's

On a different note, a spake out of turn regarding my "reliable" lingo She stopped stopping on the stop/start and instead flashes ECO at me 3 times per brake push. I can only asssume the battery is neaing the end of it's useful life because the alternator was replaced just before I bought the car and all other systems are performing well. I noticed it did this occasionally, but only if I had been doing short runs. But now it's doing it even after a five mile trip. More expense as I need a new battery for my old Rangey too

I'm off to the garage to sob into the sawdust pile

You'd think they would have a way to monitor the level either by eye or by asking the diagnostics rather than having to fanny around depressurising & whatnot

The level is still checked with no 1 Eyeball, you just need to get it into the tank first....and that needs the computer!

Wouldn't worry about the S/S - it's very sensitive to the battery; hasn't worked for well over a year in our C4 Picasso, but no sign the battery will not start it, even when it was below -10 last winter. Less strain on expensive alternator to my mind if it doesn't work!!

I checked mine without depressurising, the tank is reachable from above to give it a good wipe clean first, on the c4 picasso you can pull off the black plastic bumper insert on frnt n/s bumper and you will see tank, might need torch, fluid was up near top of tank and no hydraulic fluid leaking anywhere .

The thing is some of us regularly check all sorts of levels and things - so why make it awkward! The answer appears in the desire to make us replace our "consumer goods" on a regular basis. God help the Automotive Car Makers if the "right to repair" legislation on white goods ever gets applied to them.

I checked mine without depressurising,

That isn't the correct way to do it and it will likely be over-filled otherwise. Bleeding is also performed with the diagnostic tool - which pressurises the piloting actuator hydraulic circuit, changing through all the gears in order to force air out of the circuit.

Gooood news everyone

I took the dive into wife's murky clutch issues and did all the suggested diagbox stuff.

Wife reported the car has stopped playing up and even feels better to drive

While I was at it, I also programmed the new replacement keyfob, which I am pleased to say, works beautifully. In fact, her indoors decided it was far better than her old fob and promptly snaffled it for herself, ha ha

It's been over a week and no more jumping into gear when starting.

I'm still convinced these boxes start in 1st with the clutch disengaged, as it were. I can't otherwise explain the jumping into gear and stalling upon start with the gear selector in "N"

Whatever, the glitch seems to have gone into hiding. But I'm prepared for it if it shows it's face again
