1994 BMW 740iL ABS Pump Problem

Hi Guys,



I have another issue that i want to run by you,

in the past 8 months, i have had to replace the ABS Pump & Master Cylinder 2 times.

It is now coming up on the 3rd time.

Symptoms are as follows,

After i have driven the car for up to 10 miles,

Ride appears more sluggish, (Like brakes are engaging)

The result is that the car wont move in drive or reverse and cannot be moved in neutral.

Like brakes are fully engaged.

In testing, distance gets shorter.

the end result is that i let the car sit for 1 hour,

then i can drive it for a shorter distance.

The Parts that i replace have been New OEM replacements.

it appears that after i have replaced the parts, the car runs ok for 2 months.



In trying to resolve this issue,

i want to ask if the issue is related to a Trans Program error that i am trying to resolve.

I have replaced the speed shift sensor in trans, MAF, Both O2 sensors,

replaced trans fluid & filter.

car rides sluggish in 1st gear.

I am getting 1221 stomp error now.



Could the issues be related, could 1 effect the other?



any advice would be greatly appreciated...
