Hi Guys,

I am trying to diagnose my non-working heated front windscreen and I can't seem to get into the MFU diagnostic mode as per the Rave and as per many posts I have read....

Am I missing something stupid here? I am pressing the heated rear screen button and switching on the ignition(not starting but to the point where all the lights on the dash come on....also tried it in the spot before that....still nothing).

What gives?

TIA

Andy

 

If you have a D2, then you don't have an MFU, you have a BCU that does lots more.

 

They have a certain resistance they are supposed to have. but at the same time make sure its got power going to it.

 

Yes I have a D2....so no diagnostic testing for the D2 heated windscreen(and other electrical stuff)?
