I cut the tab, centered the rack and steering wheel and connected both you should never compensate with tie rods, always center the rack whit the steering |

You're not afraid of the rack disconnecting itself ? People are saying to not cut the tab.

The tab is largely for ease of fitment, no?
The intermediate shaft is splined and when properly tightened the pinch bolt will hold everything in place. The pinch bolt crosses through the ground out ring so there's little chance of it popping off either. |

If the steering wheel is held in place straight ahead there should be no reason to cut the tab for the wheel to be correctly aligned. Others have mentioned this also.
I do however note this rack looks different to the one I installed. It appears not to have the servotronic valve installed. |

If i should not adjust with the tie rods, which i can understand, then the only option is to cut the tab and adjust the steering wheel. |

I posted a generic picture to show that maybe the tab could be rotated.
it is not an M3 rack cut away that tab as I did strange that no other on the forum had this 30° misalignment, maybe they are all doing it the wrong way? if you look at the black plastic tab collar there is an arrow, it should align to a mark on the aluminum body when the rack is centered. then you have this 30° misalignment of the tab that I had to cut off |

I also had to recalibrate my steering angle sensor, luckily for me, ISTA-D does it very nicely. Last edited by Traf; 02-21-2017 at 11:20 AM.. |

how do you know you have to re calibrate the angle sensor?
I didn't simply did a few lock to lock wheel turns and the yellow steering error symbol on the dash disappears. I really don't understand how all other on this forum lined up the rack without cutting the tab? I had a long discussion on this forum a year go, and all treated me as a fool to cut the tab. maybe they are using the M3 steering column bottom part? |

You can read your steering angle sensor, put your steering wheel straight and if the value is 0° +- 2° then its good, otherwise you should recalibrate. Last edited by Traf; 02-22-2017 at 01:02 PM.. |

So basically the issue still stands that simply adding servotronic to your $VO still wont actuate the valves correctly? Adding the aformentioned attribute does not give you the "M" software? It only gives you the base model servotronic settings? Still better than nothing so long as the electronic assist doesnt interfere beyond low speed assist.

I have had the excessive castor dialled out of the front end and now at standard setting (approx 6%). That has cleared the lump as you applied more lock. There is no less feel or less self centring which is pretty miserable in any case. I was still getting intermittent operation of the servotronic function so went hunting again. Found a discussion re servotronic on a 7 series and the poster suggested resetting the steering sensor with Ediabas. I reset the steering sensor and received a multitude of error messages for DCS, ABS and servotronic. Cleared all the errors with INPA and had a look at the steering angle in INPA to check whether all was well. I then found a facility in Ediabas which reads the servotronic operation. As a result tracked down the coding in the JBBF file that adjusts the current to the valve. Re set the coding of Comfort-Strom with NCS expert to Wert 02 and went back to Ediabas to do some tests at different speeds. At 1 kph the current to the valve is 800ma and at 40 kph the current 462ma. The steering assistance has now eventually settled in and is not stop start. I think re setting of the steering angle sensor was the fix. As an experiment I attached a 6v battery to the valve and the assistance was too much, felt like a taxi. With a 3v battery it is about the same assistance as what I am getting at parking speed. Hope this helps. As usual the risk is upon yourself in respect of mucking around inside the ecu's. |

Do you re-use the stock steering lower joint assembly? Or, can you use the M3 joint (it looks more robust).
Looks like the 1M uses the "active steering" lower joint assembly: 32306769166. Only E82's with AFS use that joint. A regular 135i uses 32306769157. M3 has its own unique assembly and part number... https://www.realoem.com/bmw/enUS/sho...diagId=32_1516 |

This thread is awesome to read because it seems you found solution to every obstacle.
The real happy ending would be though to come up with DIY before you guys forget all that great work you've done. I feel this mod would make the 135i perfect for me. Last edited by dzid_; 12-20-2018 at 11:59 PM.. |
