Hi everyone, I had a problem with my dipped beams not working but everything else working fine, diagnosis from an auto electrician was a relay in the engine bay fuse box ( this is a sealed unit ) so after hunting high and low for a R03 fuse box one could not be found but after a lot and I mean a lot of research I found out that you can replace the one you have with one that has a higher part number so I now have a R04 and these are simple plug and play obviously disconnect the battery before hand, but sourced from neo brothers for £134 brand new came within 2 days and works perfectly, I’ve also used this site before for the DPF additive tank and same deal
