[Robby25377]

good evening new here I’m looking to replace my partners abs pump but what should i check 1st before doing doing the whole replacement



P04B1
And
P012D
Was diagnosed by the aa

This code is largely generic and refers to non communication of the abs sensors....you don’t mention which vehicle you are referring to? I’ll guess.....BMW or VW?
I think I’d need a full scan of the abs system before replacing the pump.

Abs pump was scanned by aa and has no abs for past month abs light still on and sorry seat Ibiza

Sorry but I don't recognise any of these codes relating to the ABS system.
I'd suggest a visit to a VAG specialist who will have VAG-COM (now VCDS) and they should become more specific.
For a scan, budget £45, for a new pump £350+ or yours rebuilt for around the £200 mark.

Top advice.
Don't throw money away on a new pump before being sure it's the pump.
I lost my abs and light was on and all it was a sensor that had moved slightly out of place.
Diagnosed by vag specialist, £40 and a cup of tea.

Thankfully VAG -COM can identify each individual wheel sensor plus pump coding and whatever so the diagnostic scene seems pretty good.....that will rule out sensors and reluctor rings etc.
I remember replacing an ABS pump on an elderly Mitsubishi once......it didn't cure the fault
Bye bye profit

Exactly.
I remember he connected the vcds and drove the car very slowly.
One of the sensors was giving different speed.
