Fault code 18072

[kite]

Hi All
Daughter's A3 is nor playing ball.
It has recently had an ECU replaced due to water ingress.
Car has run fine for a couple of weeks.
Last 2 days the engine is cutting out and throwing the code 18072.
Can't find this code on the wiki, had search round and found nothibg definitive.
Could this be a faulty loom ?

Error 18072 ------- Intermittent

Steve seems to think its wiring related.

18072 (P1664) Unit injector solenoid valve activation. Electrical fault in current circuit.

Open circuit in wiring or short circuit to earth in engine wiring harness

That looks like a problem with the injector power supply from the ECU on the brown/yellow wire.

Not filling the fuel filter just means it takes longer to get going as yours does not have a lift pump in the tank but the O rings on the plastic connector could be the problem.

Yeah seen that. The car is 10 years old now and has run faultless.
I slso suspect the injector loom.
Will talk to the guy that dibe the ECU tomorrow.
