First post - Hi.

I'm trying help someone - her 2001 Z3 3.0i just failed it's MOT on electronic stability system faults, both front suspension arm ball joints, and a number of minors. Things like this never come at a good time, but without her car she has no way of getting to work short of leasing.

I absolutely trust the garage that did the MOT and they are trying to be as helpful as possible, and then some.

What I'm asking here is can I do some of the work for her to save on bills?

Fault codes logged that threw the ESP are:

C1E30 - Lateral acceleration sensor - faulty
C1E21 - Pressure sensor 2 - faulty
C1E20 - Pressure sensor 2 - faulty

What's involved in replacing these sensors, and how big a job and what tools are needed to change the ball joints?

Many thanks
Steve
