2004 2.0 Hdi Passenger Under Tray Fixing

[Pk222]

Hi

 

Am trying to understand what screws/nut I need to replace the missing ones on the passenger side under tray ie not the engine but underneath the main body.

 

The hole on the under tray is square and hole on the body is round.

 

Looking at a c4 service manual (couldn't find an equivalent c5 one) I think what I might need is screw 73 or

78, 79 - am really getting confused as to how the under tray will attach to the body.

 

Here is the pic I found on the c4 forum if it helps

Would really appreciate if someone could advise what I need to order as there aren't even that many anchor points to use zip ties/string.

 

Thanks in advance

I ordered these but these aren't going to fit the round hole in the body.

The screw looks like what is on at the moment but no way the cage can fit in the round role on the body.

I'm not familiar with the C4 under trays, but when my fixings became loose on my C5 I removed them and replaced them with some 5mm bolts with penny washers either side, then a nut to secure the bolt where the fixing had come away. The undertray is then put in place and held with a washer and wing nut.

The bit that goes in the square hole is called a hog ring, Citroen part no. 703018, the button that pushes through it (and releases with a 90° turn) is part no 703016 or possibly rivet 7013V8. They are the same as on the engine under tray so you can have a look at those. Up to RPO 09740 there are 29 of these to cover both sides (not inc engine under tray) and from RPO 09741 there are 18 plus 11 of the rivet. These part nos. are the same as the ones quoted in the ebay listing but whether they are identical to ones supplied by a Citroen dealer I do not know. There are also 12 (6 each side) nuts with built in washers, part no. 693997, holding on the side under trays.

 

This says the parts are genuine Citroen ones http://www.ebay.co.uk/itm/Citroen-Peugeot-Engine-Undertray-Cover-Pin-Screw-Clip-703016-703018-Genuine-/141059413369

 

I could not find a picture of the rivet.

@john - think these are probably the bolts. One thing I am having difficulty figuring out is how does it attach to the round hole in the body unless the round hole is also 5mm or maybe the washer /nut is on the other side of the hole?

 

@paul - the parts in the eBay link are the ones I already have but can't figure out how the square part attaches to the round hole in the body, even had a look underneath today and no luck. It does go into the underway hold which is square but even that is loose ie will fall out immediately.

 

What are the RPO references you mention?

[paul.h]

The RPO is the car identification no. It can be found on the door sticker that has the tyre pressures and paint colour no. It will also be in the car maintenance book at the front and if you have any receipts from a Citroen garage for servicing, it will be there.

 

To find the holes in the car I will need to have a look under mine next time I use it. I remember seeing them at the back bumper, the square bits going in to the body and then the button going through the plastic undertray to hold it in place.

[Pk222]

Hi Paul, think they might be different than the underbody ones then where the hole in the body is round. Will see if I can get a pic today or might be a local garage job.

I have looked at our car, a mark 2 C5 2007 estate and the fixings are different. There are mostly nuts on the outside edge fastening to studs welded to the floor but on the inner parts the buttons are a plastic type with a central bit that pushes in but to see what they go in to would need the undertray removing. From the parts diagrams and using the RPO no. they have a part no. 856553 and the picture shows a metal cage that the button pushes in to. An internet search on the part no. though just shows the plastic button, so maybe it just pushes in to a hole in the chassis and expands to stay in place  http://www.ebay.co.uk/itm/CITROEN-C2-C3-C4-C5-C6-DISPATCH-BERLINGO-DS3-WHEEL-ARCH-LINER-CLIPS-X-10-856553-/360672269281 . For an earlier RPO no but still the mark 2 C5 (up to RPO 11034)  the part is 7013V8 and it still shows the cage.

 

I think you would be better using the parts diagrams with your VIN to see which part numbers are actually used on your car, but checking the parts diagrams for a mark 1 C5 gives the ones previously mentioned, so maybe you have the rivet 7013V8 parts and not the ones you got from ebay which may be for an earlier year C5. These parts do not seem to be on such as ebay so you will need to use a Citroen dealer who will ensure the correct parts are supplied
