Rear lights, parking lights not working

[Pykea93]

Hello! 
The rear lights(driving/parking lights), number plate lights and the front parking lights stoped working after i conectetd a trailer (with LED lights) last week on my 07 berlingo van

Any idea what can be wrong? Do any one have wiring diagram for a 2007 Berlingo 1.6hdi (75bhp)  manual transmission. the vin number is VF7GC9HWC8J045068 

I have checked all fuses just to be sure (with a multimeter) but cant find a fuse spesiffic to the lights thats failing...

Have you tried a BSI reset?

Had the same problem with a partner I just was taking 12 volt from the headlights and connected to the position light circuite worked fine and was quick easy and cheap fix but for sure not the most elegant way

Yeah tried it but not sure ive got it right... is there any way to see if the reset is complete?

Any ide if there can be any extra fuses some where that isnt in the book?

I suspect whoever did your towbar didn’t use a wrongly named canbus relay (another story!) and your trailer has effectively drawn too much current throughthe side light circuit and the bsi has turned the circuit off... a lexia session will confirm...

Or your trailer has a wiring fault and it’s blown a fuse you've not found, seems odd though as both sides of your sidelights are off different circuits?? I predict the former is more likely...
