When I start my car the 4x4 light sometimes comes on.
Usually I can turn the engine off. wait a couple of seconds turn it back on and all is ok.
I have done test with the car in 2wd and 4wd and the 4x4 does seem to work (when the light isn't on). It spins in 1st, 2nd and 3rd in the wet in 2wd but doesn't spin at all in 4wd.
Could it be the accumulator thats knackered? The car has done 84,000 miles. I would have thought it would have been changed at some point as it has Full Service History (I'll check the paperwork tomorow) but could it need changing again?
