Citroen XM Forum

You probably wouldn't notice the difference between charcoal and Hurricane grey trim, just keep looking out for a charcoal one, if necessary.
As said, Citjon has a car with complete tailgate, but the trim will be in Hurricane Grey.

As there are no pieces actually missing, You could repair that trim by removing it, roughing the rear side, adding some reinforcement and either gluing, or plastic welding it. Just ensure the broken edges line up well and it will be nearly invisible.

Thanks, I think I will try a repair first

Hi again, the XM had a slight problem when idling, it was a little bit rough. Today the engine started surging without any accelerator. I think it is probably the AICV, does anyone know the part number or where I can get one from? I have attached a picture of what I believe to be the AICV. Also, does anyone know how to get the auto gear shift knob off? Cheers…Derek

The Idle compensator is P# 91541077 to Rp 4984, or 0345.58 after Rp 4985.
Your image isn't attached, so I can't be sure this is what you mean.

The chances of obtaining one are slim, but before condemning it I would clean it and the throttle flap/housing with solvent. I would also clean the crank sensor and idle control valve connector pins.
The idle control valve is probably just sticking due to built up carbon deposits.

To remove the auto gear lever there is a screw under the gaiter. Remove the screw and turn the lever 90 degrees. I can't give more detail, it's years since I've removed one.

Another thought regarding raised idle is that an air leak into the manifold will cause this to happen. Check the throttle and idle control valve are lubricated and closing and check the rubber bungs for the idle control valve are not leaking.
Being a Map based system it won't affect fuel mixture, unlike a MAF based one.

Hi Thanks for this. I have an AICV coming, so when that arrives I will fit it and see what that does. I have cleaned everything with Carb cleaner but that didn’t do anything. Here’s hoping a new valve does the trick. Cheers…

The diagnostics on your car are fairly limited, but if the Ecu detects a problem it will store a code, which you can read with a Blink Code reader.
It will detect a sensor out of range, or the idle control valve being open circuit, but won't store codes for irregular running, or any fuel pressure issue.

Yes, it’s a pity I can’t just plug in my diagnostic machine, as I can on my Ford Explorer. When the engine starts to run poorly, the engine management light comes on but as you say, it doesn’t appear to store anything, as when I start it afresh, the light has gone and only comes back after a short while, when the engine starts to race. I think I have found the two pin blink code connector, in the engine bay at the front near side but I will need to take a proper look. I will fit the new valve when it comes and see what happens. Cheers

If the engine management light comes on, the Ecu will be storing a code. Build a blink code reader and all should be revealed.
