Error code 88 - ABS precharge pump, need some help/advice!

Recommended Posts

Not sure about ISTA, unless it's an auto-correct of INPA. DIS and INPA are part of the BMW software - same as NCSExpert. DIS and INPA are rather more user friendly than NCSExpert (INPA the most simple) and I think you can activate the ABS bits in either.

ISTA is the current version of official BMW diagnostic software (DIS being the previous one). There is a procedure for DSC bleeding in INPA but usually it doesn't work like it's supposed to do.

I also went brand new, and at the time it was the NZ$ equivalent of 240 pounds - there are a number of posts about people having issues with rebuilt units and sending back and forth etc. Theoretically a new one should last as long as the original... hopefully :lol:

Where did you guys source your new modules from?

 

My car has thrown the DSC light with errors 104 (error steering angle control unit), 92 (pressure sensor, plausibility precharge pump) and 88 (precharge pump).

 

88 Has a frequency of 255.
