As already stated fitting a second hand airbag ECU is plug and play. Just make sure the one you are getting has the same part number. I bought one off EBay and fitted it about 5 years ago. I just plugged it in and reconnected the battery and it has been fine since.

I would have thought the wiring would be a spur off the interior lights above the doors. You might see something by pulling out the interior light.

To close this...

No further recurrence while in France or on the journey home. Car looked over by my Cit specialist on return to UK and no fault found. Did get them to replace fluid though as that was overdue.

Update parking sensors fitted now got the wires through the bulk head now its just wear to put the switch or should I get the genuine one

I have found from my limited exposure, that the 1.6 ECUs seem more blighted than other engines. No idea why; it's a motor with great potential that seems to have faults within the controller rather than sensor failures.

A filter like that has to be physically suffering a massive blockage before it impacts on the ability to lubricate as required. There are greater potential losses in the oil pump gears.

You could possibly assume a running clearance of 1.5 thou on all rotating/sliding surfaces except cam lobes. That way, the bearing dimensions would allow you to...

I just did my wife's c5 exec 2003 today here is how I did it.

Go into the bsi ecu page and select configuration.
go down the list until you get to the pressure sensor present line.
Highlight the pressure sensor present line it will highlight in green.
Click the authenticate button and it will change to missing.
Ignore the pressure line which will...

You need to fuse the 2mm internal stiffener to the A pillar pressing and the hinge metal. This- to do properly - requires good understanding of welding.

I have a couple of litres of Saab manual gearbox synthetic oil in the garage, it's called MTF0063. Could I use that in my HDi gearbox?

Your fault sounds like my Xantia when I had a duff electrovalve controlling the turbo.

It's usually this that brings on the light. A vacuum leak / duff electro valve causes overboost and this in turn brings up the anti-pollution message. Mine does it very occasionally, and that's had the dpf removed already. In fact I'm trying to source some...

All good; a substitute set of leads and coil pack and she's like a new one. I've not heard such a smooth V6 for a while.
Glad you've got it sorted, they're a really nice engine when they're running properly, hopefully I can get mine back running properly one day too... :?

Interesting. Used to work for them. Worst garage ever, didn't know anything, sold very questionable cars. Used to borrow tools from the good skoda garage 5 miles away. Suppose they are owned by vw now so it's all changed! It's amazing how perceptions and realities change in such a short space of time. Dare I ask: could any recent British...

The clue is in the parts - the factory diagrams are often inaccurate.

The bolts pass through a two piece collet and nut setup. It's designed so the collet expands when the bolt/nut is tightened, locking it into place within its sliding range.
The reason i asked was my friend likes to leave me bits on top of wings/headlights etc so fall off/move...

yeah the bsi has a luggage label on it so i thought something was up (not just the mileage).

Seats should fit OK. Do not forget to check out the Partner equivalent while shopping for spares.

Be aware later models may have side airbags in the seats and things like pretensioners for the buckle (if fitted not sure on these it might be in the belt instead) as these are likely to be different.

Later dash is different (round vents etc) ,...

LOL....too much fussing to re-wire as the ciggi lighter goes dead, I'll just feed/squash the wires past the doors, the seal is soft ;)

Cheers guys...

You are probably bouncing on a fortune ! :-D

sorted, took the feed from the coil pack.

Erm!!!!!

Think it was changed in jan when car went for MOT and service.

last night , 2.5 hours constant motorway at up to 90mph.. 3 adults and dog and boot full.. 47.1mpg,, which seems the same as always :)

^ Yes, it hasn't happened after that even though i've parked in the same spot several times over the weekend. Phew!

I have posted this a few days ago, but i picked up a 56 plate C5 just over a week ago and had my suspicions about my speed. By running with the gps it turned out speedo was Under reading by 8mph! Just intuition that made me drive a little slower. Looking at the speedo and rev counter with the engine off the speedo needle was pointing lower than...

hi guys thanks for the info I will try takeing the wires of and the battery sounds like a fair shot I will let you know my findings will also forward the 8digits as requested cheers jim :)

I sometimes name my cars, the c4 is obvious, its called lezzie! I give her a change of clothes now and again. She has pride of place on top of my facebook page, and the mantlepiece, and kitchen door, on the shed,,,,,,,,,,,,,,,,And I do not have green blood. Had orange for a while does that count?????????? :lolhit: :rofl: :tongue:

Re refilling the additive tank I did it on my present C5 and found it to be a very simple task, firstly I bought the additive from Citroen as they now offer a new version (Infineum F7995) which reduces build up of ash on the particulates filter so worth it in the long run, the kit comes comes with the additive, a long length of hose with a tap and...

As I said, if you want to remove them and disable the warnings. If you remove them, they ain't gonna be fitted.

Yeah anyways I think its best to to stick to late Xantia /C5/ 406 with HDI engines.

you'll probably need the bearing support tube as well, they get chewed up usually. (cheap from ECP)

I have a pair of them in the garage that are surplus to my requirements since I went HDI

Well most are either petrols or hdi's and the only one that's close is one that had one owner and 50k miles no tax and near full mot and just managed £430 :(

I did think the alloys were original but it shouldn't affect insurance anyway as they are worth pretty much little anyway.

Need to find out when the belts were last done really as that's...

Some time ago, on the Might be useful one day principle, I saved the extending aluminium handle from Bettaware broom or similar - one of those that you twist to lock/unlock with a plastic hand grip on the end of the top section and a threaded plastic socket on the other.

Today I found the perfect use for it - much more useful than as a broom...

Well this is it.. cornwall the car had luggage for two.. not heavy..

Comming back from manchester i had my three drawer and lid tool box full.. very heavy.. a second halfords tool box.. two trolly jacks.. pipe flare tool.. lexia.. box of extra pipe work. Two axle stands.. and me...

Hi all, I have just upgraded to a 56 plate C5 VTR, and after the xsara find it amazingly comfortable and am well chuffed. Bought it at Auction and it has 48000 miles on it. 2 things wrong, first thing was the boot lid opened everytime you blipped the fob, wd40 in the catch and job sorted. The speedo was under reading by 8 mph as checked with tom...

I failed to locate the speed sensor. :oops: Where I should exactly look at?

I'd prefer to see steel banjos brazed onto steel pipes rather than welding: welds are brittle and no matter the method (gas, MIG TIG) it's very much harder to get a reliable and durable oil-tight joint. Brass banjos of course need to be silver-soldered (tinsmith's, not plumber's or electrical, solder).

Any gauze filter would seem to be a bit...

Good idea xac - yes i'll be taking it off to swap round electric/manual window windermechanism - (I have just hung a replacement door in the right colour).

Thanks, John

They are the C4 vts ones arnt they??
Looking closer at the pattern Timmo I think you're right and they are Resolfens...

Shows how big the cars have got - in some cases the Resolfens look small on the C4s, whilst on that Xsara they look huge...!

addo - right - I was a little quick there ;-)

When I have done regens on Lexia, it has never worked, in fact the last one I did on a C8 made the pressure differential larger, not sure how :(
If you have a 1.6 hdi, you need to get it removed correctly, I have much experience with these, and you cannot easily trick the car into thinking all is well. Remember the car will still try to regen...

Addo of far far away fame(!) had a very good idea on a much earlier post (July 2012) when he said that he had used 2 blocks of 38 and 17mm under the front mushroom bush and the P bracket assembly respectively. So I set up the arm and scribed a line along the held in place Pbracket and arm. Clamped arm in vice and used a can of pipe freezer on the...

Why do I always look for the complicated solutions first. Peered into the socket and at the back of it was the mangled remains of a fuse and part of the iphone charger internals!! Amazed it hadn't shorted out as some of it was metal. Anyway extricated this and all works as normal!!! :) Note to self look for the simple solution first!!!

Depends what the fault is with the radio - IIRC these have an amplified aerial that is prone to going haywire, leading to loss of signal quality - this might worth pursuing first. Should be possible to fit a radio from a higher spec car though.

The rear brakes get fed off the suspension system (how, I don't know. Witchcraft?)
No Witchcraft, simple plumbing: a pipe runs forward from the rear (anti-sink) accumulator to the Doseur valve (separate sections for front and rear circuits) then another goes from the Doseur back to the rear where it 'T's to each calliper. These very long pipe...

Has he done simple checks like fuses & see if the brake lights are working ? A faulty brake switch can cause it not to release from park.
