also water level light came on and went off only for a couple of secs checked level and seems fine i think this may be a bad earth too

 

Might be worth checking MKIV.com and looking at the wiring diagrams. If they use the same earth point or something similar then go check it.

 

Other than that, it seems a bit strange, Mr "Nice" Harwood may be able to answer the electrical questions better than me....

What i thought was the water level light wasn't! it was the low oil light! which only came on for a second going down hill on tick over.

Checked oil and it was above the low level but filled it up anyway

and light didn't come on this morning on my way to work. Problem solved

 

The door locking syndrome continues also the opposite unlocking

has happened. Its difficult to explain but i will be driving along everything as normal then the doors just lock! some times they just remain locked until i finish my journey other times i goes into a fit of clicking. EG if you put the key in the door and lock and keep locking it again the motors still operate but the locks are already locked. Also sometimes the lock/unlock button inside the car will only lock or unlock when the above problem occurs.

 

Any more pointers

 

Thanx

I doubt very much that this has anything to do with an earthing problem.

Most likely is either one of the door motors/switches are playing up, or, as already mentioned, the locking switch on the door may be at fault.

 

I'm not brave enough to rule out the CDL control unit, but I've never heard of one playing up before.

 

Time for a door stip down I think...

Yep thats right only now its locked all the time, the only time it will open on the central locking is if the door is open but pressing the button to lock. Nothing happens when it is pressed to open either with the door open or closed(no clicking etc). In fact even with the key or the alarm fob it will not unlock the central locking.

Have been to my local breakers today to obtain the bits but the boss was not in so i have to return tomorrow.

 

Thanx for all the advise
