Which Comm 2000 Unit?

[Hax]

I folks - I don't know if anyone can help - but I'm hope you can!

 

I have a 2003, 03 plate Citroen C5 2.2HDi - which has just started showing an airbag fault just recently. I took it to a local garage and they diagnosed it as a COMM 2000 fault and ordered the part in for me. However, when they replaced the faulty part with the new one, the fault persisted. They investigated further and it turns out that they had the wrong part - they ordered it based on my car's chassis number which says that it's just an SX (which it is) and they don't have auto lights and wipers, but mine does - hence the problem.

 

However, the price for the correct part (new) has now risen from about £200 + VAT to £339 + VAT so I'm looking at trying to get hold of one off ebay (or the likes). The problem I have is the numbers on the "old" unit don't seem to match the part numbers I've seen for other units on sale.

 

The numbers I have taken from the old unit are:

 

Delphi: 12275626R

 

And

 

PSA96595097XT

 

 

Whereas the part numbers for units I've seen advertised tend to look more like this: 6242.S9, 6242.T0, 6242P3, 624294 and 624233

 

Is anyone here able to tell me what the part number I need is - or, does anyone here know how I can find out?

 

Any help would be greatly appreciated.

 

Many thanks,

 

Adam

The part nos. beginning with 6 are (I believe) the Citroen part no. and not the manufacurer's no.

You could try the Citroen service website to get the part no. - you need to register but do not need to be a dealer/garage/etc.

The SX does have auto lights and wipers as standard, so I don't really think you have got to the bottom of this problem. Is your local garage a Citroen dealer?

 

Have you checked the wiring under the front seats for damage? That's what caused an airbag fault in my C5. The dog got hold of them!

My SX has auto lights and hypothetically wipers although they don't actually work. (auto wipers, autolights work fine)

Hi folks - thanks for all the replies and apologies for my delayed thanks!

 

Anyway, the problem's been sorted now - I was unable to source a 2nd hand unit so told the garage to fit a new one (at an extortionate cost). Anyway, as it transpires, the new part wouldn't work either - they spent several hours fiddling around with it until they actually started to do some "real" investigative work and found a broken wire under the carpet in the passenger footwell.

 

After fixing that, they removed the new device and put the "old" one back and all has been well so far (*touches wood*) - and there was no charge to me as I'd only just bought the car from them and they gave me "free" labour - for a problem they had agreed to fix before I bought the car - but had clearly failed to.

 

Anyway, end result is me being a happy bunny as far as the airbag is concerned.

 

However, the anti=pollution fault is irritating me a little. I'm suspecting the EGR valve as there was apparently an old fault for it in the computer. The garage was supposed to have cleaned it - I asked them to and they say they have but I'm not sure I trust them. They also said they found a broken pipe that they repaired.

 

Anyway, the fault is still present - albeit intermittently.

 

Can anyone tell me where the EGR valve is (from the point of view of standing infron of the car with the bonnet up) so I can have a go at cleaning/replacing it - assuming it's the sort of job that can be done at the roadside.

 

Again, many thanks for your previous help and thanks in advance for any help you can provide with my new query.

EGR VALVE isn't a road side job! but its located on the passenger side of the engine above the gearbox.

Cheers for the reply techbod - had a feeling you were going to say that :s

 

Oh well, guess I'll have to part with some cash then.

i would get your elloys fluid and particle filter checked before fitting a egr valve. a faulty egr valve would cause poor running.
