Thread: Error codes fails on differential

I've just bought a 2010 D4 3.0 and when I use my Nanocom and read error codes, it fails on Differential, but continues to check and clear all other modules.
I don't think I have the locking rear diff, so thought maybe someone has turned it on in the CCF, hence the failure when it doesn't actually have one.
So I go into the CCF and it shows the diff as not being installed. Should I try to turn it on and see if that will help.
Also I noted that my speed is limited to 180kph, maybe I should turn that upto 250 in case I need it!

Checking underneath is the easiest way to discover whether an e-diff is fitted or not.
