Help needed…error codes

[Danny172]

Hi all
I’m after some help I’m getting rather confused!
I have a 1998 1.9 m44
The main issue I have is with the abs. I would have a very intermittent fault with the abs light coming on. If you restarted the car, the light would go off and stay off for some time.
It’s now pretty much on all the time.
I’ve scanned codes and have this (pics at bottom)
I know these suffer with the pump ecu solders going bad..and think this may be the issue here?
If so, can it be repaired, or replaced…where would o find the part number? I also get the impression any pump change, the pump has to be “coded” to the car?
Also whilst scanning I got a “70 camshaft position sensor”..I’ve deleted this code before.
The issue here is that there is no check engine light and the car runs ok, albeit a lumpy idle.
My question here concerns the replacement sensor. I would love to go down the bmw genuine route..but nearly fell off my chair when I saw the price..nearly £250! Is this the only route, as I’ve seen some meyle or Bosch ones advertised more sensibly?
Any advice greatly appreciated!
Thanks
Danny

Looks like the abs pump motor is at fault could be worn or sticking motor brushes, strip down only way to find out. Some videos on YouTube worth watching to see what’s involved. As to camshaft sensor source either Bosch or Siemens brands don’t buy cheap eBay ones. You could take the pump unit out an send it to Ecu testing and have it repaired.

Thanks for the reply, my plan is to take the ecu off the side of the abs pump and send it off, that way I do t disturb any hydraulics etc

If it’s the motor is at fault sending the ecu part of it off for testing and repair wont fix what’s broke. Best do some more diagnostics on it, INPA can do a activation test on the pump motor to see if it works. If it runs the it will be the ecu.
