wtf is up with these cars need help.....
so the other day I replaced the MAF and o2's........cel was still on so I disconnected the battery....waited 30 mins and reconnected......CEL was now off but abs asr light came on......drove a little bit and it went off too.....so now the car runs good and has no cels but then I went to put the window down and wtf none of my windows work.....turn the car off and back on and the windows work but the express up/down dont work....even after trying to initialize them......so ok I can live with them not going on express......for now.....so I thought......I get into the car today and one express works on the left rear door.....both windows on the pass side work but no express and the drivers window goes down.....wont go up then all functions but the door locks die on the driver door.....WTF could this be I am at wits end......no cels yet stuff doesnt work......and all I did was disconnect the negative terminal on the battery and reconnect it 30 mins later.....all fuses check out live and well......what is up with this car?????????

It's not a problem. The windows just need to be re-initialized. With all doors closed, all electronics off and key turned to position 2 (but car not started), roll down all the windows. Then press each window's button up until the window rolls all the way up but keep pressing for another couple of seconds. Do that for each window and they'll all be reset. Do it also for the moonroof. Have fun!

Oops! I just noticed you already tried initializing.

You probably need to pull the battery again. Then follow the reset procedure. Resync the windows, steering wheel, sunroof.

Before you tear into your door panel, I need to ask a stupid question. Have you held your FOB (keyless entry device) to the passenger door and pressed the close button for a few seconds? The window will not reset in the down position. I experienced this issue last month. Pressed my lock button for a few seconds; window closed; then I reset the window.

Disconecting the battery will NOT re-set the ECU adaption!! It will only turn the CEL off. You need to visit a MB workshop to re-set the ECU adaption when you change the MAF or 02 sensors. Sad but true

Most of the "problems" listed aren't really problems, they are normal any time you disconnect the battery. Turning wheel lock to lock few times gets rid of ASR/ESP warning, rolling windows up & down a few times while holding for 5-10 sec should reinitialize windows & etc. To reset ECU adaption you have to do the pedal reset trick (although the best way is to use a star diagnostic tool to reset all adaption parameters). It may seem like the car have gremlins, but everything you described is pretty normal, nothing to worry about.

Are you sure Abalone??? hmm don't know I may have to throw in the flag on this one... I recently changed my MAF (3 weeks ago) and my car drives Night/Day I mean I had to hold on with two hands when I jumped on the highway I thought for sure I was going airborne

I do not agree. I tested numerous time 0-60 before and after also I monitored fuel trims with obd2 r4eader before and after reset and as far as I can see Battery disconnect totally resets ECU to factory specs.

I also was told that a battery disconnection would reset all the values. But after talking to both a MB staff and Cory at Kleemann they told me that the only way to reset the self learning ECU adaption when changing a 02 sensor or MAF was to connect it to a MB computer (or what it's called?) and reset the adaption and after then all the values was back to zero. The battery had nothing to do with resetting the values according to them
EDIT: Found the letter in his last e-mail
"And yes, it's true that disconnecting the battery will NOT reset learned adaptations- that can only be reset by doing a default initialization with the factory SDS machine.

flag on this one. I've also heard the same thing before as well now that you mentioned it. This is a big scam as MB tells the DIY guys (us) that only the SDS machine can reset the Values back to factory specs. I REALLY doubt it.. unless the ECU unit has a rechargeable battery or some type of small battery that keeps the memory of the ECU- Just like a Computer motherboard it has a small cell battery that stores the memory of the Bios/values/settings/ so even when you cut off the power it still stores the values. Only way to bring it back to it's factory setting is to remove the battery wait a few seconds (discharge) and replace the battery. (yes guys I know about the jumper just trying to make a point
)so conclusion.... I'd say it's safe to say that MB wants you to go to them for everything.. another example - I had to change my shifter a while back and MB stated that I had to program the TCM/shifter with them..not true plug and play

The Star diagnostic machine does allow to reset ALL variables, but you can still reset some with pedal ECU reset and powering down ECU. Those mainly reset tranny adaption but they don't do everything. Either way its nothing worth fighting over haha. MB will always say "don't do this, don't do that, (blah blah)" because if they were to tell you how you can do it on your own they wouldn't make money. Moreover, they hate aftermarket parts not b/c they are inherently bad, its just it takes away from their own profits of selling their own parts. 9/10 times its all about money (as with everything else in this world).
