My light came on at 9k. The pads are fine there is something faulty with the sensors or ecu and can't seem to reset with BT. Apparently this is fairly common. I might take it in next week.

There's a bulletin about erroneous brake pad replacement warnings. The software has an error, and needs to be updated.

The DME is the car's computer. Yes, I have lag at low rpm's now. Will try the wastegate valve conversion soon. Check out the last few pages of the 29.2/lag thread in the turbo section. Doubt you have much choice unless you can live with the warning symbol on your dash.

Based on paperwork I got from my dealer last week, E89X-09-03-510 equals 33.0.0.6.
Background on my reflash: I have an 11-2006 build E90 that was on original software (and HPFP!). I bought it in November 2008. I recently got a brake pad service indicator and took the car in. The SA said it needed a reprogram, and did not actually have worn pads. It was reporting 255% brake pad life (summarized in SIB 34 02 08). I had already printed instructions for the tech based on the helpful info I got in this thread, and instructed them to do the "wastegate retrofit". It is called "conversion wastegate valve" in ISTA-speak. The SA was not very familiar with the process, but he was very helpful and found a tech who knew what to do. Note: The SA said they had to select this option before programming, not after. The data sheet they gave me shows that my cars old software was E89X-06-09-540 (23.2.2?) and the new software is E89X-09-03-510. Elsewhere in the paperwork, the new software is listed as 33.0.0.6. I took the car in last Friday morning, drove a 528xi for a few hours, and then got my car back that afternoon. Driving impressions: It feels about the same. I don't baby the car, and I've given it a bit of a workout since. The ~1 second long start up rattle is gone, but I don't detect any lag. The low end torque is still good. Note that I do have an AT, so it might mask some effects. Take off in D seems to be a bit smoother when the car is cold. Strange software upgrade effects I noticed: -I think the font lettering for "D" and "DS" got slightly smaller -Service Info menu is only available when stopped with foot on brake -SOS service interval is shown where is wasn't before -My radio station presets got erased, and my tone controls, but EQ settings and seat and mirror positions were retained. Summary: The new SW is OK as long as you have them do the "conversion wastegate valve". After reading about all the trouble that a few people have had, I was worried about getting new software. Luckily, mine went smoothly, and I still like my car! That sounds like what I have to do? Thanks Bruff!!!!!!!!!!!!!!! VERY Good info!!! Last edited by jayely1; 04-26-2009 at 11:38 PM.. |
