EPS Light - GT1 assistance required

[Colinm101]

OK

So I bought my 2.2 Z4 with the EPS Light on. The steering is fine at speed but obviously heavy when parking maneuvering.

1. Fuse is check and is fine
2. Did grease nipple "mod" to assist when fixed which helped slow maneuvering massively.
3. Lubricated other visible steering joints under the bonnet.
4 Purchased GT1 software, says no communication possible from EPS unit.

I have driven 1000 miles in the car in the last week, The steering worked for over an hour in the last 100 miles after stopping the car turning off the ignition etc so I know the EPS does work

I thought it may be the steering angle sensor and I could calibrate it but the GT1 only lets you set the wheels straight ahead, not do a full calibration?? (like you tube videos out there show for other models)

Any techies who could shed some opinions??

That's strange that it is not letting you do the full reset. I used it for my previous 530 (E39) It allowed me to do the full turn full lock left, then full lock right, then I was to tell it when I had the wheels dead straight

 

[Colinm101]

I thought the GT1 would let me do a straight reset of the light? Then it would pop back up if the fault was there?

 

[WNeill]

No, there's not just a single 'clear fault' command, you must do the recalibration sequence

 

[Colinm101]

Do you have a gt1 buddy?

I know it's a lot to ask but is a step by step too much to ask?

Might have found one after LOTS of searching

Try it tmw
