Morning all, Wife was taking our mk5 tdi 170 golf engine code BMN to work this morning when it just completely cut out. I have been out to the car this evening and scanned it using a topdon scanner and got the following codes
00576 terminal 15 electrical fault in circuit
00883 ignition/starter switch terminal s fault in circuit
00884 ignition/starter switch terminal x electrical fault in circuit
01744 ignition/starter switch terminal d electrical fault in circuit
00885 ignition/starter switch terminal 50 electrical fault in circuit.
I cleared these codes and replaced battery as it was weak to crank but it still won't start.

I have ordered an ignition electrical switch for tomorrow but are there any other "hotspots" to check?

I also noticed the replacement battery didn't take long to start loosing charge almost like something was draining its power more than just cranking. Engine was turning over fine and cambelt looks ok.
The other thing I noticed was the central screen on the clocks was bright with ignition on firdt click but as soon as turned to the final click before rolling the key over to start the central screen on clocks dimmed noticeably. Take note this was before engaging starter.

Thanks Sam
