MK3 CD Drive Part #

Does anyone know if it's possible to buy a replacement CD drive for an MK3? Basically I need the equivalent of part # 65839241764 (which is the MK4 DVD drive) but for MK3.

I looked on getbmwparts and RealOEM but neither list this as a separate part for sale.

Thanks!

In the past on these forums guys have listed URLs for sites that had drives for MK4s and MK3s I seem to remember. Do a search for the drive and laser repairs and you should find some referances to the MK3.

I searched but couldn't find anything about the MK3 drive replacement. Perhaps I'm searching for the wrong keywords. Any chance you might be able to find a link for me? Thanks!

Two questions. Do you need a complete drive or just the laser? I found a laser by googling BMW MK3 laser repair. Optical Laser pickup for BMW MK3 Navi CDM-M2 Mechanism

Didi's pictorial instructions on this forum for the MK4 laser repair lists many places to buy drives and lasers. Review them. One of them that I looked at had drives also. I think one was Gerner. The complete drives were not cheap but might be worth a search. Your drive is probably a CDM-M2. One of my old MK3s also has the VDO number 22SY591/23B.

Thanks. I think i will need a complete drive, not just a laser since I suspect the motor may actually be the problem. I see that there are at least 3 different models of MK3 drives. Is there a way to tell which one I have without opening it up?

You will have to open it eventually anyway. It's easy, just pry under the back edge of the cover with a small screwdriver and the cover lifts up and slides out. What is the 22SY number on the cover? The ads list several of these numbers for the same drive. My bad unit was a CDM-M2 2.3E and 22SY591/23B and it was built in APR.2001. I would think any of the MK3 drives would work and they are probably selling later ones anyway. Are you sure your unit has not been bricked? If so you would need to send it to Wetzler Germany or to Australia for reflashing.

I'm sure some of our German friends on this board can tell you the difference between item 1, 2, and 5 in this ad.

I know I will need to open it anyways but I was hoping to figure out the exact replacement cost since that greatly affects my decision of whether it's even worth fixing. Essentially if I have to spend $250 to replace my MK3 drive I'd have to really think about whether that money would be better put towards a Dynavin instead. If I could get a replacement drive for $100 or so I would think about it but ironically it seems the MK3 drives are much more costly than the MK4 ones.

My unit isn't bricked since it still works part of the time. But most of the time if I put a map disk in I get a read error on the disc so either the motor or laser is going bad.

Are you trying a copied map disk or an original? If a copy then get or borrow an original to test. It sounds more like you have a laser problem than a drive problem. There appear to be an 8 pin laser for all but the newest MK3s and a 10 pin laser for the newest MK3, 65 90 6 922 720. I have one of those which has the 23F number. It is my spare back up nav for my MK4. It is a very good unit and I suspect a little faster than the earlier MK3s. I think all the earlier MK3s had numbers, on the label, prior to 23F which would be the 8 pin laser. My dead MK3 has a 23B number. I know you can find both lasers at at least 2 places on line.

I've tried both original and copied map discs and get errors on both. The reason I suspect it may be the motor and not the laser is because I also have trouble ejecting the CD. I have to turn the car on and off a few times while trying various methods of pressing and holding the button before it will finally eject.

Really appreciate the info about the lasers, I guess my next step will have to be to pull the drive and check the lable and see which one I need.

What are the numbers on the outside label of the unit? If there is a 23F then you have a CDM-M3 drive I think and otherwise a CDM-M2. I expect there are several guys on the various forums that have a bricked MK3 that you could get cheap and salvage the disk drive. The bricked units have to be reflashed in Germany or Australia to come back to life. I never found anyone in the US to do that.
