I'm having trouble with my ABS its has a bosh 5.7 module.problem started about 4 mounths ago, after about 13 miles all the lights came on. A quick test showed a fault for osf w/speed. put a w/speed sensor in and no more 13 mile grace. Blocked out the module and found no out-put to osf. Sent module for repair. told irreparable by ACTRONICS. bought a complete mod and hyd/block (used) from quarry motors, £200. the same bosh number but different bmw number. just fitted electrics and it would not communicate at all, ista/d or ista/p.I also took it to a back street guy who specialises in bmw programming/coding. no good!
bough a module on ebay from usa. same bosh no. same bmw no. Shipping/import duty £105 all in. it had a permanent fault for o/s/r wheel speed.
bough another mod/hyd unit of ebay, same bosh no. same bmw no. £141. it also had a load permanent faults.
ebay refunded me for the usa module. so i sent that module to ACTRONICS. £205 later they say its was sorted.
when i plunged in that module i also lost steering/suspension/odometer. tried clearing down fault codes and was looking good. It lit up before i got to the main road. lots of communication faults to other the modules.I sent it back to ACtronics. They say module is ok.
At the moment, running original module. Just break problems now. it was awful when the steering/suspenion/spedo were also down.
I'm having a break from this problem now. not a nervous break down. but not far off.
any advise would be appreciated
