Thread: Faults with 2007 Discovery 3 SE - help greatly appreciated

Boothj


A faulty high pressure pump will show a variable pressure they just have to be running the car at that time to see it happen so if you can pinpoint the time at which it happens you can help in the diagnosis eg. cold, hot etc
The faults you are telling us about can come from a lot of different areas such as steering angle sensor, low suspension pump pressure, alternator fault etc
If you can you need to try and isolate a fault outside the lights and whistles
such as slow suspension operation, pulsing dash lights and the like
Good luck

Try replacing the tail/stop light bulbs.

The cause is very unlikely to be caused by a faulty or failing suspension compressor. Either a fault with a component monitored by the ABS ecu or an intermittently failing alternator which does not normally occur, as alternators usually at most only give a brief early warning of pending failure before they fail totally.

I suggest that you look at the wiring harness behind the front left wheel to see if its come adrift from its mount against the chassis rail and has subsequently been chaffed by the inside of the tyre causing a fault with the wheel speed sensor. This is a common occurrence. If OK there then the steering angle sensor may be faulty or out of adjustment.

How long ago was the brake light switch replaced?

Thanks for the advice. I'll have a look at those things. I replaced the brake light switch on Saturday and it came up with the faults again today.

I'll try that. Are there genuine light bulbs or just generic?
Thanks for the help

Thanks mechanic2you. I have tried to find some sort of common thing, but no luck to date. I'll keep trying
