always if you have a probleme with communication
always try other interface diag(other then clip)
before start to repair

Loom corrodes from fusebox under bonnet to ecu due to water ingress, worth a try, start at engine control relay and work from there.

Hi

Just an update.....

Checked wiring and relays -- no faults .

swopped with know working uch , different part , and got communication with all control units.

The same fault in uch on both vehicles.

I am busy tracing what circuit is causing communication to be down .

So far it seems pin no 8 on P201 plug in UCH N2 are shorting inside UCH .Still need to check where this wire goes to on wiring diagram.

Is there anyone that had this fault before?

Will check tonight in these uch units for any visible faults.

Hi still busy with these vehicles.

Seems that i will have to get some other uch's.

Replaced some parts inside from other good unit but can still not get to find why the line for immo decoder ring are being pulled down to ground.

hello
is common in these types of uch fail

but the most common problems I had was that the indicators give no more no less
or the central locking fails

Hi,

I also have a broken BMT N2.
Have you found a way to fix it?
Thanks.
