there is no accelerator pump in an EFI vehicle so pumping the pedal is a useless exercise

What can I do when I got code u2105 in my car (Opel Astra 1600)


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?
http://en.wikipedia.org/wiki/Opel_Astra
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.

I put a new battery on my 2003 Saturn vue. It will start then die. what is wrong with it.


because you have disconnected and replaced the battery ,it is possible that the CPU program in the ECM is corrupted. Use a scanner to reset the program and go from there.
