Year of Manufacture *: 54 plate
01397= Venting solenoid for level control 31-00 open or short to ground
Naturally Autodata has no data on this.
The pump does not run at all!
(Would this be expected if the ECU has logged the above fault as a safe mode or does this indicate additional problems? )
The solenoid valve seems to have a low resistance of around 10 Ohm, is this reasonable?
Does anybody have any idea what sort of wave forms I should be getting on the solenoid valve terminals so I can check with pico whether the supplies are good?
(I have read that broken wires can cause this. though if this is the case it looks like an absolute bear of a job unless some sort of repair kit is available!)
It is kind of important to get this right since (AFAICT) the valve is not available separately from Audi and a new pump is over a grand!
