Citroen XM Forum

Is LH drive different to RHD perhaps? I have RHD XM & 605 - no way 605 pollen filter will fit XM. I made a filter for XM, but it restricts air flow - I have to run the fan at a higher speed to compensate.

...I come across an ad selling a new master brake cylinder, I buy it as a spare, you never know when you'll need it.

Hopefully and probably never, the only item that seems to wear is the rubber button on the outside.

Does anyone know what the numbers are, the injector code for the Lucas pump. I noticed that when the engine is cold, there is a clicking sound a little more, as if the engine is not working well, the same thing happens when the engine is hot, if I give it more gas, it sometimes starts that clicking is heard and after some time it stops being heard and there is a normal sound.
Or maybe it's the hydraulic lifter that doesn't open the valves well and you can hear a clicking sound.

Run some injector cleaner through the fuel system before condemning the injectors. Use an engine stethoscope to trace the noise.

For sticking hydraulic tappets, an engine flush normally works.

I will try some engine additive to see if it will improve the condition, it doesn't always click, only sometimes and it lasts 10-15 seconds and then everything is normal.
The current mileage is 219.500 km, so I thought it might be time to change the lifters or hydraulic lifters.
The noise sometimes occurs while driving and then stops, so it is difficult to determine with a stethoscope where the clicking is coming from.

You're not confusing the clicking from the hydraulics pump are you. 10-15 seconds sounds about right for a car with new spheres.

The noise may not be mechanical at all and be a result of the fuel injection going over advanced, causing a knocking sound. Check the connection to the injector needle lift sensor is Ok.

I poured the diesel K2 cleaning additive, I'll see if the problem will appear again.

...I really don't know what's going on with this air conditioner, whether it works like that or something is wrong with mine.
the same thing happens as in the summer when it is very hot in the car that the air conditioner turns on by itself, now the same thing happens when it is cold, the temperature on the display + 25 or +30 degrees, when starting the car and the air conditioner turns on by itself.

Do you mean the outside temperature display, if so, the sensor is faulty.

The air conditioning is also used to demist the interior in cold weather.
