hi! I have a 2004 disco 2 td5 with 63 000 miles on the clock. The problem Im having is the amber ACE light is now constantly on. Previous it would only come on in cold weather conditions. Plugged in a Nanocom that i borrowed from a friend and it shows fault 02-02 road speed signal missing. Speedometer works fine, cruise control works fine. So it must be a problem between the slabs ecu and ace ecu. Is there anywone who can point me in the right direction as to Where i start looking? Must mention that there was a waterleak through the windshield that i fixed before this summer.

I bet- especially with the windshield leak- that one or both of the accelerometers aren’t getting a signal.

It may seem you are right. Plugged in the Nanocom and Its showing that the lower accelerometer fluctuates between -0.05 and 0.00. Upper accelerometer reads -1.42. Also couldnt find any fault codes today, but the amber light is still on. Im stumped.
