BMW Z4 SHORT CIRCUIT
Bmw z4 blowing a 10A fuse tested the circuit with one of RMS LOAD CAGES what a brilliant tool. I found the circuit from the oxygen sensors had a short .replaced both sensors and replaced the wiring. JOBS A CARROT 🥕the pics are all before the repairs was done.

Hi mate I have a BMW 4 series 2019 hardtop with a n/s/r window stuck up due to water ingress in the motor .it has a dead short in it. the roof is in op I've tried to undo the pressure release screw on the pump and turned the release override in the roof but still like its full of pressure in the hydraulics any ideas 😱

Hi Huw sorry for the delay you have to release pressure from the struts then unclip one of the hydraulic arms by the passenger rear and a long pair of pliers and manually pull the latch off and it all folds down then you can remove the glass to access the window module

citroen c4 picasso c156d
hi everyone i have a citroen c4 picasso with a c156d, passed over to my workshop from another. we had a fault code for the right rear abs sensor which was a corroded wire which we have repaired and the ABS lights are gone. This is the 2 pin style on the motors and not the older 4 pin ones. Reg : AF67 YGV VIN: VF73ABHZTHJ882074 Fault code: C156D- permanent not clearning i have an xtool d8w only at our garage, when attempting to do electric activation or the parking brake nothing happens, when doing replacement of motor and caliper using the diag nothing happens. Vehicle no longer has parking brake.

Power the one motor up with separate power and earth and see and hear if it is actually doing its job first then road test then do the adaptations to the parking brake should sort your issues 👍
No crank no start
Hi lads new to the group. Got a 2020 Vivaro as a no crank no start condition. Main relay powers up you can hear everything switch on and fuel pump prime. Turn the key, nothing. When bridging starter relay vehicle just cranks but doesn’t start. Where would you go from here? Vehicle also has an adblue remap if you think that could be linked. Cheers!

The adblue module on this is possible to be in the tank. Have you done a system scan to confirm this?
