3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
New sound to deal with. When braking normally, just before reaching a full stop, I get a solid clunk in the rear of the car. The wife says, "I thought it was just good brakes," and doesn't think it needs to go to the dealer. I think it's got something to do with the drivetrain back there. Any guesses? U joint?

Thanks for any help!
What year of the car , which model , auto or standard gear box, what the milage on it?
OK! there are some pretty annoying noises that come out of the E46 that you really cant get rid of. One of those happens to be a clunk when shifting. You can make it go away for a little while by lubing the splines on the driveshaft but in my experience it always comes back eventually. this is especially true with the GM automatic trans because the output shaft on the trans is sloppy. That was happening on 323 and 328 E46 models made betwen 1999 and March 2000. Simple repair kit is needed($200) which consist of new output flange and some washers to get rid of this pissy "clunk"(avilible at bmw stealershiup), but as I said it applays to above models.
In your case , as your car is made in 2003 and still under warranty forget about any mechanical problem like u-joint, flex discs ,differential or cv-joints!
What you need is reprogramming an EGS(transmission ) module on your 2003 325, that was common problem on 325 and 330 and BMW North A merica knows about that. Harsh downshifting 2 to 1 cause the clunk or thump in final drive , that is what you hear just beforE stoping. Go to the dealer shaw them attachment below and tell them to do reprogramming, it is for free under warranty. This definitely will resolve the problem. Good luck !
BTW there is an eeprom for that on your car and service will know that!
When the problem is solved , you owe me a case of good beer- Ha , Ha ,Ha !
Thanks for the info again. We had the dealer do the reprogram today, and it hasn't clunked, yet. I'll let you know if it does. This'll serve as a little bump for those who haven't yet solved the clunk!
I have just purchased a 1999 323i automatic. I have exactly the same problem. Just before i come to a stop CLUNK. I thought it was something loose in the boot but checked everything. Do you think mine could be the EGS too. How much is BMW likely to charge me for the fix?
Hi ! There is no transmission program update for 1999 323i.
The problem you encounter is detailed in BMW Information Bulletin # 24 09 98 as being caused by excessive axial play between the output shaft and the output flange. A relatively simple repair kit is available, part # 24217515388, which includes a new flange and some washers and clips(cost about $200.00).You need 1 hour labour for that. Tell your dealership to review the bulletin.If you decide to go ahead with this repair, tell them also to reflash transmission module , clear adaptation and programm DME- it will help!
Thanks for the info zibby. I'll get on to it asap. Strange thing is i've noticed if i put it in tiptronic it doesn't clunk as the transmission only goes down as far as second when i come to a standstill.
