Disco 3, everything, for the diagnosing of. x1

[red5]

As you may or may not know, I have replaced the nearly dead/writted off D3 with a newer one, hoping to repeat the miles of reliable commuting.

This hasn't gone entirely to plan - I will say it's mostly been utterly faultless however.

2007 2.7 tdv6 HSE Auto

[red5]

No drive, thunking into gear/out of gear, suspension drops, randomly Parking brake fault etc etc
Basically it's immobile.

Usual culprits -

Cheapo stop/tail lamp bulbs.
Worn brake lamp switch
Battery.
Wiring under n/s/f wheel liner (sounds familiar? thats where the previous one had crappy repairs)

WTF tail light bulbs cause gearbox symptoms?

[red5]

In order -

Brake lamp bulbs replaced with Ring™ ones.

No difference. Bah.

New brake switch ordered. Not fitted yet.

As I was back in office i used the good, non-agricultural battery tester.

Ah.

WTF tail light bulbs cause gearbox symptoms?

in short, yes.

[AutoshiteBoy]

Yet you fitted Ring?

[red5]

Yep. OE spec. Why?

[AutoshiteBoy]

I never had Ring down as a quality brand. And I've sold enough of their stuff.

Couldn't get Osram and they do a job. Really cheap is cheap.

However, the battery is u/s.
The 9.0v drop is the killer, not the cranking voltage. New one to be sourced. Will fit the brake lamp switch as well as it's probably the original.
