LEW coding request sent to Launch

.thanks for letting us know .but i was unable to scroll down to see the outcome after the autologic suggestion

Good post Shazam!

Quick question regarding the repair, when you say the module was defective and needed to be coded, are you saying that you need to re-code the same module?

If so, would this be considered a flash, since you are not taking old data out and inputting into a new module, but actually inputing "new" data into an otherwise dead module?

I guess I am confused at the jargon sometimes, and just wondered what the outcome was. I know sometimes Launch R&D wants us to be specific in our requests otherwise they spend time chasing what doesn't really exist.

Thanks!

I'm wondering if he installed a used ABS module on this vehicle (very common for techs to do). If so, that replacement (used) module will not recognize the steering angle sensor and thus it is necessary to initialize/reset the steering angle sensor.

If this vehicle was an E46, the Launch should be capable of doing it. For E36/E38/E39/etc., the GT1 or Autologic will be required to perform this function.

This is not a software glitch as much as its an OE coverage that isn't currently available.

On the bright side, they recently added the steering angle reset on the newer chassis E60/E65/E90/etc., but the caveat on those vehicles is that flashing is almost always required when replacing control modules.

Don't you love BMW? hmm

This is great infomation Eric, thank you so much for input, please share more "real world scenarios" with us as you can.

Are you saying even the factory tool can not perform this function on a E36/E38/E39/etc?

Very good point that sometimes even the OEM tools don't work 100% of the time, or always contains every function possible. Ask any dealership tech and you'll see what I mean.

The GT1 (Group Tester One) is the BMW tool and it will perform the function. The autologic is the only aftermarket tool that I'm aware of that will do it as well. Awesome tool, but at $10K per car line I like my Launch alot.

          Yikes!  You could almost BUY another car, haha.

          Thanks again Eric!

You are correct, the angle sensor is part of the SZL and angle sensor codes usually require replacement of the SZL which does need programmed. I'm up to date on BMW, so yes, I do love BMW wink

We need to know the exact trouble code in order to determine what's actually required, initializtion or coding, to resolve the problem. Either way, this is pretty high-level and usually will require the autologic or GT1.

A new DSC and steering angle sensor was fitted. When he attempted to code the DSC with the X431, the ZCS variant coding was wiped out in the cluster. (all 000's) The cluster variant coding was edited correctly with the Autologic and the DSC coding was performed. Steering angle adjusted and end of line was run. Car fixed.

Eric,

i recoded and ignitialized my steering angle sensor on my E39 to mate with the new DSC control unit without any problems. So the Launch can do it.

Read the post carefully. LEW coding was not offered. This is what Shazam has reqested to be added. For whatever reason, the Launch wiped out the variant coding (ZCS) in the cluster when attempting the DSC coding. After this no coding was allowed as the vehicle variant could not be identified. This had to be corrected with a higher level tool. Steering angle adjustment was never the issue. THIS IS NOT A COMPLAINT, ONLY A REQUEST TO ADD LEW CODING.
