Hi

For this fault P0621.......... 99% you are looking at the faulty Alternator.

As for P1811 and U2103 check the multi plug at the ABS Module also there is a another multi plug under the Battery stand check those both plugs for poor connections.

Hope this helps.

just checked the history on this car and we changed the alternator in September and the fault was there before , so any other ideas lads

Hi Smirnoff_rules,

Was the alternator original or after market one :questionmark:

If it was after market than I think you wasting your time mate they always give problems.

[omglol]

I've had Astra H with exact fault few months ago ... broken regulator on alternator. However, when I changed the regulator, I accidently switched wires and the DTC was back on, only the alternator was now working normally (after restoring wiring to the original, of course). Since this DTC does not bring MIL on, I left it that way.

That's a pain . It was a Lucas unit l will have to return to g.s.f . Can't understand why the fault was there before , only changed the alternator because it packed in not because of the mil light ?
