Warning Lights

Hi All
I have ABS, TC and hill decent warning lights staying on on my Discovery TD5 1999, the garage said the diagnostics code is 4084 and it could be a number of things wrong.
To trace the problem could be costly, does anyone know where I should start to look?

Do u know what diagnostic equipment did they use?....cos if it was a dedicated one then this code must have had a description e.g. "...shuttle valve..."

first of all check the play in the front wheel hubs...if there is any that's a start www.discovery2.co.uk / Front Wheel Hub / Bearing Assy

if not that's another possibility Land Rover common ECU failures

unfortunately both of them are a bit expensive ........though it has nothing to do with the engine

search three amigos for more info.

I am currently having the shuttle valve replaced...

I sincerely hope i'm wrong but IMO that's wasted money.

it's what the diagnostics returned and it's under warranty.. so hopefully it is the rigth thing.. otherwise we will be having some conversations..
