Hi all further to my earlier post we have 3 BCU that seam faulty 2 from an AR and 1 from a 2017 +4 .
The symptoms are as follows.
1st AR intermittent rev counter fuel gauge.
2nd AR new fitted side lights on all the time with the key out and the lights switched off.
1st AR refitted the same sidelight problem.
2017 +4 2amp fuse5 removed to check supply was replaced and now has sidelight as on AR controls.
Questions
1 Is there a reset system?
2 Is there a startup system eg power ignition on fuses in order.
In all 3 box,s the 2 blue LED ,s come on at power connection.
Any thoughts would be appreciated
