Adblue injector leak - bitdi

[Notjoe]

Hello,

P20E800 - Reductant Pressure Too Low static

I've had this code now for a couple of months, the injector was caked in adblue and there was a heavy leak directly under so I've replaced.

Unfortunately it's not stopped the code... so now I'm guessing the injector wasn't at fault and it's something else.

Could it be the supply line? Or anything else?

Does anyone know the part number for the supply line? (2017 3.0 bitdi)

Thank you

It probaly needs a new tank, what is the VIN? Which diagnostic system?

Odb reader is diagnostics and then local garage swapped the part and clearer my codes.

The ABS fault is because the pressure sensor failed (£102.12) and he kept driving it so the ABS pump burnt out and that's £3014.81 parts alone. Not to all readers, if the dash says the brake vacuum sensor is faulty, stop driving!

In my experience yours will need the pump 4G0 131 969 J at £860.40 and control unit 4G0 907 355 G at £526.80 but there is no software update of the engine management unit on yours.
