Another JB4 Q

Post by Chriseve41 » Wed Nov 06, 2019 11:55 am

I have been offered a relatively cheap Jb4 EWG for my m135i however I think the car I have is a PWG (car production month 05/2013)

Will the Jb4 still work or would I have to buy a PWG one?

Thanks in advance

It will still work provided the jb4 harness has all its original plugs/wires intact that are used to connect PWG.

EWG harness is an add-on which you won’t need but some JB4 customers cropped harnesses of unused plugs to tidy up the install - I know as that’s what I did for my JB4 install on my EWG m135i. Ask seller to confirm the number of connections and colour of the wires - compare their answer with JB4 install instructions to ensure suitability of the harness.

You will need to update FW from EWG to PWG - is enough time do via n54 tech forum.

100% it will work?
Just download the latest pwg firmware and it should all work yes?

Thanks
