Battery tests good..how do I check ground.. and what related to two jobs that caused this.
Thanks

 

At this point the new brake light switch has been molested..what position should the little clicking things on sides be in to reinstall?
Thanks

 

Did Hard Reset as suggested..but no change.
+Voltage running is 14V..when not running 13.6V.
When Brake pedal is depressed all is normal, car obeying commands( Up..down.)..but once brake is retracted..car drops.
What can it be.

 

If you saw corrosion on the terminals than that should be your first thing your looking at. I don't think that the work they did is causing your issue.... What kind of shop did you take it too?

At a certain point however you need to bite the bullet and take it to a shop or independent land rover shop. We can only give you so much guidance over the internet.

I will say from my personal experience with the same symptoms it was corrosion from water getting in.

 

Idk....sounds like the brake switch to me; like it was not properly installed the first time.

 

Anyone spill coffee or other liquids in the shift lever area? This will also throw wacky codes if it drips down to the mechanism.

 

Thanks ..now that the brake light switch has been in and out and tampered with by my neighbor( after independant shop first put it in trying to fix original problem.)..how should we set it up back as it was too re einstall it..or is it rubbish now?

 

No sign of residue from a drink unless it was water dropped by mechanic.

 

It’s rubbish. Get a new one.

 

Is there a link to how it should best be.installed.Atlantic British has a 2 minute video ..
Dropping bottom panel and one just abouve it and it seems to be a simple screw in screw out of the switch.thanks
