Hi
Vauxhall Zafira 2016 2.0 litre diesel
Orange engine warning light came on a few weeks ago, ODB scanner came back with adblue sensor error:
Reductant Level Sensor Invalid Range - Engine Control Moule (ECM). DTC Code P1050
Took it to a garage in Clydebank area, all they did was add some adblue to tank (which it didn't need) and cleared the error code. A week later it came back.
I can clear it, but it comes back next time car is started.
I read this could be due to wring / corrosion issues, so took it to garage specialising in car electrics. He took one look at the above error, said it was unlikely to be wiring, said he'd never seen that error on a Zafira before, and advised me to look into the costs of replacing the whole adblue pump/tank assembly.
I'm hoping I don't need to pay to replace the whole brand new adblue assembly because it looks eye-wateringly expensive - Arnold Clark Vauxhall in Garscube Road quoted £3500 for new adblue tank, pump and control unit. That is insanely expensive.
There's plenty of adblue in the tank and im getting no other errors.
The above error, based on what I have learned, concerns the adblue level sensor, which, along with the adblue temperature sensor, is built into the adblue tank. In other words, those two sensors are NOT sold separately.
I've bought a used adblue tank assembly, going into garage this coming week, can only hope everything functioning in this assembly.
Cheers
