Evening all - sure this has been done to death, today my C110 scanner arrived and I took a look at the ABS issues via the 20 pin socket in the engine bay. The issues were as per the photo - Front Right Sensor, Rear Left Sensor and ABS pump, worryingly the front right was replaced a few days ago, I also give the rear left a really good clean (could still be faulty) biggest worry and cost obviously the ABS pump. I cleared the codes had a few mile drive and retested but codes returned. I may get an hour tomorrow to swap the rears over too see if the fault moves. The car is booked into an Indy Specialist on Thursday- I was hoping to resolve myself but I am now a bit worried that my codes are not reliable.
Age old ABS issues.

The module will need to be replaced (code 71). Clear the codes, rescan and the other codes may go.
DIY the module will cost you £30 ish secondhand but will need coding with a laptop and NCS. Garage doing it may be very expensive if they want to use a new module.

What is the build date of your Z3?

I found that a single faulty speed sensor can cause secondary faults on the other sensor & pump.
Mine had a NSF sensor replaced this week after I had faults for NSF/OSF & ABS pump. I suspected it was just NSF as the fault occurred just after that wheel forded a very deep puddle.
Had NSF replaced and fault codes cleared down, now light is off and no further codes recorded.

It would be unusual to have a pump error thrown by a sensor. They tend to be intermittent though. So you may find it pops up again down the line.
Garage have confirmed I had a dodgy sensor and my pump is goosed typical so I am on the lookout for an ABS pump urgently Part Number 34.51-1164896
Try changing the sensor first - you may find the pump is ok after - worked for me.
Just done a weekend of 1000 miles hooning around Northumberland at full chat with lots of hard braking and zero ABS issues since replacing the sensor.
