Glad you got your problem fixed! The DME needs to see 3 key cycles of no fault codes consecutively to make the light go out. I'm surprised the light didn't go out as the dealership should've cleared them once they replaced the O2 sensors.

Also the fault code needs to be seen twice consecutively to set the light. And disconnecting the battery does not erase the fault code memory.

 

Hmm... I reset the codes myself to no avail a number of times. I assume that we are talking about a reset using a generic OBD tool, yes?

Also, thanks for not correcting me regarding my statement regarding an ECU reset. I saw your post in the other thread that what I performed was a "cluster reset" (whatever THAT is... )

 

Yes, you would need a generic OBD II to erase fault codes. I don't believe a generic tool can reset the DME however. The keycycle thing (supposed to be drive cycles, my mistake) is what the car's selftest procedure. I posted a fairly detailed description of what it is on the other thread you mentioned

 

Barnabas, there is good example of why reading the bulletins are the first thing you should do with a repair.

 

Not you too! lol Our instructor CONSTANTLY hammers us on checking sibs before any repairs are made. I have like a stack of sibs a foot high lol. I wish BMW came up w/ a better system for attaching appropriate sib #'s to an RO.

But do tell me, where is this good example of reading sibs?

 

Post 22 and 24 compared to 25's results.

The sib's aren't going to be attatched to the RO. It is up to you to use the tis resources. It is very easy to use and is divided by engineering model and group#. Don't forget to review your puma cases too. Unless there was a test plan that said different, based on the bulletin the sensors didn't need to be changed. Frequently the problem with 02 sensors is just programming parameters that need to be a adjusted. A mini with 100k maybe.

You won't be able to remember all the details of different models. Just be aware they exist and be able to maximize your resources to point you in the right direction.

 

I think webtis can use some work though. The group numbering system is alright, but man sometimes they got stuff that doesn't even seem like it belongs in there!

I really do wish they attached SIB #'s to ROs lol. Would save tons of time. I have 0 experience w/ puma cases as we aren't allowed to call the tech hotline.

 

Yeah, they need faster servers and short cuts so you don't have to start at the begining every time. The groups never feel 100% right, but you get use to it. The frustrating thing is that it is translated from german to british english to american english. There can be some interesting use of terms.
