Hello,

My boyfriend owns a 2006 RR Supercharged, the mileage is unknown some documents say 200-300k, the computer says 600k and the dashboard shows 420k. Go figure.

He bought it last autumn in good condition, however we quickly discovered it had a "suspension fault, recommended speed 50 km/h" and the car being unable to drive faster than that while raised/lowered, basically it's stuck in the middle. It was just a minor nuisance until the car started making horrible noise and jerking motion when accelerating rapidly and last month he completely changed the gear box and it eliminated all the jerking and the noise, plus a total oil change everywhere was performed literally last weekend.

The suspension fault remains and recently another "transmission fault, limited gears available" popped up after two or three suspension faults. I've come to think it's somehow related?

The repair shop guy said that one shock absorber is dead and needs to be replaced urgently so BF is doing that after next paycheck. The gearbox change was a costly affair and I'd like to avoid fing up another gear box if it's the suspension fault making everything else behave weirdly.

Have you guys got any ideas on what could be the issue here?

Regarding the suspension fault, the guy at the shop said he couldn't get to read the codes for that. Huh.

Possible that the suspension faults, and the locking out / shutting down of the EAS will generate a transmission fault as a part of the chain...especially if you try to ignore them!

Let us hope it is not the gearbox, having just changed it! (Warranty?)

You really need a dedicated diagnostic reader that can access the EAS fault codes for a Range Rover (difficult to help without knowing these), but there is only so much that can go wrong, despite it appearing very complex:

Air Compressor (in boot)
Height Sensors (at each wheel)
Leaking Air Springs (not shock absorbers)
Leaking Pipes
Leaking Reservoir (below RH seat, outside the car)
Main and Cross link Valves (one RHR wheelarch, one RHF wheelarch, one with the reservoir)
ECU (unlikely) .
Experience is the only genuine knowledge, but as time passes, I have forgotten more than I can remember

At the risk of sounding like a broken record, could it be battery related? my 2005 S/C gave me suspension warnings and limited gears available when the battery was totally dead.

Could at least be worth a try to get it on a decent charge and try it again.

Definitely need to get a good code reader on it and see what's what. Good luck!  Formerly happymadison1978
