Hi all. My 2010 octavia 2.0tdi elegance has a fault code p0562.
Low voltage detected. Check engine light is on.
The alternator puts out 14.4 ish at tickover rising to 14.8 or 9 at 1500/2000 rpm.
With a load lights heated seats windows etc it drops to 13.9.
Ive checked the continuity of the two small wires back to the ecu and all seems good. I have a small obd scanner and if i erase the code, and start the car the check engine light goes off. If i stop and restart the engine, it comes back on again.
I have fitted a new battery, so can cross that off the list. I can see no obviouse signs of corrosion in the connector or wiring, and all the pins on the ecu are there and in good condition.
So. Where do i go next with this ? Im erring toward changing the alternator, but it seems to be capable of a decent charge rate. Maybe the ecu its self has failed? I just dont know. If theres anyone that can give me advice on what direction to go in , i would really appreciate the help. As i am rapidly loosing the plot.lol.
