Hi,

purchased a 2008 x5, this error is on dash, i have had it plugged in and comes up under vtg - 55c3 - awd limp home control activated-no dsc specified nomina torque, garage seem to think servo cause when they told it to do something it didn’t basically.

Has anyone got any advice on how to DIY diagnose without paying a garage an arm and a leg, i have read about turning left to right will try tomorrow however most other advice ive seen is when other errors exist.

Thanks

Morning Jordan

Welcome to the Forum

The code your seeing is in my experience normally tied to 3 suspects (1) Battery, make sure the battery is fully charged and in good health. Engine off test the voltage at the charging points under the bonnet anything below 12.5v would indicate a problem. Engine running test again you should see 14.5+v (alternator good) (2) Steering angle sensor, these don't often fail but not impossible, driving forwards turning lock to lock normally resets and clears it. (3) Transfer case fault, Again normally robust but the poor old Gearbox and Transfer case are often ignored (even by Dealers) and not serviced. So check for any signs of leaks changing the Transfer case fluid is straight forward just make sure it is correct for your car (tip always make sure you can undo the Fill plug before draining, seen two where folks drained and then couldn't refill). Also when stopping listen for clicking noises under the drivers seat in some cases the nylon activation gear can wear/strip and may need replacing (plenty of "how too's" on the net

So I would start with simple stuff, Battery first then clear the codes and check again you may need the help of someone with a Diagnostic program to clear faults i the memory. If the Battery is the culprit then just changing it should clear the faults and lock to lock reset the steering angle sensor.

Fingers crossed its a cheap easy fix
