[elchpo]

hi all, new to site and looking for help.
mk7 transit, running then cut out .. traced problem to earth by drivers seat.. redone earth bolt cleaned up metal etc, all ok. seam to be from water ingress from windscreen bond,
been fine for two weeks, now same problem , thought id sealed screen but still a little water so going to get redone by windscreen fitter..

so problem i have is no lights on cluster just the digital mileage, and light when door open..
have checked all earths and all good , all fuses and relays are good to..

no comms between bcm and pcm.. on c3 plug on bcm noy lead pins 11 and 12 showing 11v not 2.5 as should.. i guess theres water in canbus or something but unsure where to look now. van is a 2.4 twin batt ex mini bus..

thanks in advance for any help.. been trying to try find canbus routes etc but no luck..
mk7 2.4 ex minibus
