This shutter arrangement is in the nose of the bumper and regulates air flow over the bottom of the radiator and the other rads/coolers. The flaps are operated by a solenoid block on the end. You can see the corrosion in the connector shield which is right at the front of the bumper inlet. The plug terminals were equally corroded and water was obviously being held in the connection as it had water in it when dismantled. This ties in with my wife's description of events upto where and when the first warning light came on. She was travelling behind a lorry in atrocious weather on salted roads in a plume of spray for many miles. The plug was not available from Peugeot but turned out to be a standard VW plug which is freely available. Nice one, Peugeot - NOT!

While on the subject of Peugeot, the only way to get the solenoid valve was to buy the complete assembly! The guts of £330! I will dismantle the part and look for part numbers and report back. The print out here is from Daryl's Autoelectrics in Glenrothes, Fife. It confirms (sort of) my original Diagbox printout and bears absolutely no relation to what we ultimately found as the main issue. Many thanks to Daryl for putting up with me and doing the soul destroying job to grind off all the errant rusted captive bolts on the bumper to get to the shutter assembly. He had never worked on a Hydrid4 before and, boy, has he had a steep learning curve! His final bill for labour cannot have covered the real time he spent on this puzzler. Torn tendons are a bugger when it comes to working on cars! Many thanks Daryl.

Ever had that sinking feeling that your wallet is £300 lighter than it needs to be? I dismantled the shutter assembly this morning and I discovered that the stepper motor drive is a Sonceboz (Bosch) unit. The main shutter part works perfectly with no obvious wear and is free to move with your fingers. I have tried a quick google of the numbers but haven't tracked it down yet. It simply clips in place so it is a serviceable part. I was only given the option of buying the whole assembly but looking at it now I reckon it is a pretty standard part and should be available on it's own. I have just come back from a test run via Methil Docks Hydrogen Office. Will update this as I find out more.

The markings aren't that clear so here is a written version -
PEUGEOT CITROEN
HW1 1 A444 006 / SW 27 S005 012
6460H440 (?) 12010P04516
SB MEAPCEM01
9673420580 00

I think most of it is correct except maybe the 646 bit
Oh and I think the circle mark might be an Opel badge

time to play hunt the stepper motor

That's one mad piece of design - I didn't know that feature existed! On my C5 of a similar vintage, there is a note in the handbook that says "when towing heavy loads, remove X piece of plastic cover from behind the lower grille to assist engine cooling". I can attest, that this piece of advice is redundant in the UK :D

I'm glad to hear you've found the source of the fault, and hopefully the preventative maintenance will help stop more electrical gremlins popping up in future!

Sorry - no idea on the motor!

Hi again. The large chunk of plastic is called a "controlled air intake Module". I have still no idea why it has thrown up the codes it has and it was a ****** to track. Eventually found it through an anomaly in the LIN network. A proper wiring diagram for my model would have helped so if you can track one down in your "spare time" I would still like it. I suspect the Airbag faults will creep back - just a feeling! Battery voltage (service) has settled around 12.5 volts if it is left for any time and charges at 14.6 downwards when put into "Ready", The car drives well and everything including the air con, gear selection, traction battery, sat nav and radio traffic announcements all work as they should. I am planning a shroud and some Vaseline for the plug connector when I am fitter. My knee and now my ankle are still giving me grief but, once they are ok, I plan some preventative waterproofing. Will update this thread over the coming weeks. Cheers.

Hello everyone! I have a Citroen C4 2011 semi automatic gear. I have it for a little over a year and ever since I have issues with the car, the coolant system, after some engine issues, the main screen is not working, oil is leaking service and check engine are on and now the gear box failure showed up as well! :(
What suggestions do you have? Should I just let it go or is it worth it to fix it?

Battery voltage is 12.5v in the morning. Current draw is 2.8 > 1.9 > 0.9 > 0.04 over about 90- secs ( I have to fool the car overnight by latching the bonnet catch and leaving the bonnet free so I can get the meter attached in the morning before I actually "open the car and switch on". This is Fife and anything shiny left visible in the drive might be "liberated" to a new home elsewhere). Daryl's printout I put up was not his first one, it was part way through once we twigged the codes were not helping us and as we found the intake module problem. For instance, his shows (like mine) that the FM2 module was shorted to earth but the radio worked perfectly as did the traffic announcements, sat nav etc. So we still haven't fathomed the FM2 code. The Airbag code might be real as my wife and I regularly swop drives and the driver's seat and wiring are moved back and forth all the time. I have tried using the power socket in the centre console for voltage readings but it gives different readings compared to the battery ( like 11.95 when the battery was 12.4 but rising to 14.6 same as the battery in "Ready" state) so that is going to be added to the list of things to check. Next stage is to leave the car sitting for a few days to see what happens to battery voltage/drain. If anyone is wondering why the battery voltage isn't 12.6 -12.7, it is because the BSI will still be working before and after the car goes into "Ready" and the surface charge of a fresh battery off the charger is depleted. The traction battery box fan can run for 3 mins or so after the the car is parked up along with the other normal things that happen for a standard diesel engine. So, 12.5 volts isn't worrying me after 16 hours or so.

Just taken the car for a brisk run in Sport mode to clear her throat and fully charge the Traction battery. Service battery also fully charged at the end of the run. Had 12.7v on battery for a short while before dropping with radio and fan on but out of "ready" state ie accessory on normal ignition. Going to leave her for a few days now and test her then.

Just back from a week's belated (12 months) holiday in Lochaber. We took the Suzuki lifeboat for our trip and left the Hybrid4 to ponder over the error of her ways. When I parked her up the service battery was fully charged, 12.7v. On return, I blipped her and opened the bonnet and by the time I got the multi meter fitted (maybe upto 2 mins or so) she was at 12.3v and stayed there for 3 mins. I then took her out on the street and swapped her for the Suzuki back into the drive. Parked the Hybrid4 back in at the head of the drive and took charging state volts of 14.6v, dropping to 12.6v when taken out of "Ready". Will leave her overnight and see what we have tomorrow.

Got into work mode again today. Battery voltage was 12.2v when I checked her properly today. Amp readings started at 2.9 and went down to 0.04 in less than 2 mins again. Charging voltage was 14.7v at start up and the readings at the power socket in the centre console followed the pattern from the last time - 11.9v upto 14.6 on charge. Definitely need to check cabling and power socket.
The first run was a short one to Aldi's to get essential groceries and restock fridge. It was done in Auto and the traction battery dropped to 3 bars (commonly does this in eco mode). Battery voltage was 12.6v on return. Next trip was longer and included stops at the post box, local garage to drop of wheels/tyres for balancing and Sainsburys to blow up tyres/ fill diesel tank. This was done in Sports mode and traction battery was back to full charge. Service battery was 12.7v at switch off dropping to 12.6v after 1 min. So far no error codes and car is running perfectly with proper full electric mode start up in Auto. Touch wood!
I am thinking about installing a permanent meter shunt in the battery to fuse box circuit with a plug in cable to allow external monitoring without opening the doors/bonnet. I have a power meter for Pint Pot our camper and I am considering making the meter removable on a plug in harness so I can use it on the Hydrid4 as well. Any thoughts about this welcome.

Breaking News. Sonceboz actuator motor tracked down,
1623266237934.jpg
1623266346770.jpg
And the assessment that I was £300 lighter in the wallet! Yes, I was pretty much spot on. FECK!

Good news.

car is still behaving and has not thrown up any error codes (yet ) (touch wood)

service battery still drains slightly when sitting but not enough to affect entry/start procedure and everything you expect to chunter on after switch off does and settles.

Still going to fit a battery power management meter though.

I just found several listings for that SB MEAPCEM01 by googling it.
You got there too!

The potential PSA numbers 6460H4 or 6460H440 don't come up with anything relevant (just a hose on C5).
