Centeal locking and air suspension issue

Hi guys,

Please can someone help, I am in the Essex area and have 2 issues. 1 is the rear passenger door doesnt work with the central locking. I can manually lock but it does not work with the keyless system. Please can soneone tell me is it a easy job or can someone recomend me someone

Also during the cold season I had a warning light come on with the suspension, which it would set a normal suspension and no other option is available. This only happened when the tenp was bellow 3 degress. I currently have no warning lights now but on highest level the suspension on the front looks like it is struggling to go right to the top but I do not get any warning lights. Front suspension goeals up really slowly and keeps going slower. The ride has defiantly become more bumpy which makes be belive something is wrong with the air suspension even though I have no warning lights.

Please help

Door fault will be the actuator I had the same issue but left it a while and then the front door packed in so both changed, as for suspension get plugged in

Might be the front valve block on the suspension. My front would gradually drop over the course of a week if the car was left standing. Seems to be an issue on some 12MY discos.

Got exactly the same two issues, my suspension fault is due to a failure of some box on rear near side. Booked in this coming Friday, box only £98, door fault is a fairly easy fix being done at same time. I use JSF at Manningtree, Essex. 8)

Now I got this problem with the front lowering. Replaced front valve Block sometimes during the spring last year and this seemed to fix the problem. At least for a while.
But Now with temp well below 0deg celsius the car started lowering again, first in front.

Could not find any leaks on the Springs so thinking the fault is somwhere Else.
Car is a 12 with 135 000km on the odo

The door lock mechanisms have two small electric motors within them. One is for the general lock and the other is for the deadlock. The bushes wear out and get gummed up with the bush dirt and stop working.
The motors are purchasable individually to perform your own repair, else a complete lock motor box will need to be purchased. I repaired one of mine successfully for a cost of around £4.
