I have an problem in my car and getting code U2105 and I need the best solution to fix it
Year, country?
this is covered in the factory service manual, "FSM".
for each code , there is a page, that tells you/ mech.
what the test is, what it does, how to do sub tests to isolate true cause.
my guess is the U code is in the cluster display?
best is to get a full scan of the car, OBD2 (EOBD?) to see all errors, all DTC. errors. then have all the facts, on errors.
lots of opel,, my guess 2007?

CAN Bus Error ECM
best i can do (no cars here usa) is above. google searching in Germany.
the car has many computer modules and one can not
communicate to the ecm(ECU/PCM) OR BCM.
is the car battery low>?
check all fuses. in car, in all fuse boxes, test them.
this is the best i can do ,no books on opel here.
Hi: your error code U2105 = no communication with ECM .
Kindly describe your symptom is the engine running or just swinging over.
In many cases the starter will not even activate if this code is present.
Check if your throttle has a wining noise when ignition is on, if there is no sound in this area the fault could be a blown fuse or faulty computer( ECM) alternatively the bus wiring between the (ECM) and the immobilizer control module (CIM) .
You will require an expert to troubleshoot and repair , some programming aparatus will be required should the (ECM) require replacement.
