V50 Electrics : P0620 Generator Circuit/ P1632 manufacturer control

[phmetcalfe]

H, I've trawled the forums but no joy.
I have the following code which won't reset
P0620 generator control circuit

This then leads to
P1632 manufacturer control
U0d0c manufacturer control

and because these codes have been there for a while, prevents regen so 4 months after a new DPF I have the dreaded
P242F dpf r ash accumulation

The garage can't force regen while the P0620 code is present and won't go away.

Brief history, if you accelerate too fast the radio cuts out, and I get BLIS reduced function or camera blocked every so often.

My understanding is, it's a fault with the alternator, but the code is responsible for a number of faults, faulty alternator, but this was replaced last year, faulty battery but this was replaced start of this year, or it simply could be a broken wire. Or it's the voltage regulator.

Any thoughts or advice would be much appreciated, preferably easiest/ cheapest options and if no joy then it will be chucked on ebay as faulty.

Cheers

Hi, did you get to the bottom of the fault codes? My v50 has just thrown up the same codes, and I don't know what direction to go to rectify it! Thanks in advance

the v50 alternator is a known fault you need to replace like for like non genuine alternators can give all kinds of problems iv seen this kind of thing before.
