HI,

I am new to the forum so not exactly sure how it works yet.

I am looking for some help/advice regarding my airbag ECU and would be grateful if anyone is able to offer some support.

My car is a 1999 Z3 2.0 auto. It has never been in an accident but about 8 months ago the airbag light came on. The car has been in storage for the winter but when I was driving it last week the drivers airbag went off (fortunately I wasn't hurt). My local BMW specialist (not a main dealer) has advised that the airbag ECU needs to be replaced as it is not advisable re-programming it due to the fact it has already triggered the airbag for no apparent reason. I am happy with that so started to look for a second hand unit. The original part number is 65-77-6908896 but I have been unable to find this anywhere other than the main dealer who wants the earth in exchange.

One online broker has an alternative part which he states is interchangeable with mine, the part being 65-77-8386131. I have checked REALOEM.COM and true enough my part superseded the part that the broker has, furthermore REALOEM.COM states that the parts are interchangeable. My concern is that whilst a whole host of Z3 models are listed as having been fitted with both of these parts mine has only ever been listed as with the new version. Will the older part be compatible with my Z3?

Can anyone please help and advise?

Regards

Mark

      Rumble at rear left under acceleration

      Hi, I've had this F20 for almost a year but has started a rumble noise and I can feel it to. Basically this rumble comes from the rear left when under hard acceleration at only certain revs, I'm thinking a bad drive shaft maybe ? I have a few other things in mind that it could be but thought I'd give this a go to see if anyone knows the exact problem to save me waisting time looking at the wrong culprits 😅 Thanks in advance and hope you all enjoyed Christmas 👍

      X1 problems with connectivity and Carplay

      X1 25e 2024. Intermittent problem with CarPlay , Android Auto and Bluetooth. Started off by not automatically connecting, sort by turning off car, locking, unlocking and starting car. Progressively has got worse. Have connected through cable, without cable, Bluetooth and still won’t work. Have deleted on phone and then tried to search but won’t connect. Have rebooted my phone, same for my wife who has an android phone. will now delete our profiles and then restore. After that I have run out of ideas. Fault appear to be that Bluetooth is not being broadcast by the car. Any ideas what to do next would be appreciated

      SLIPPING CLUTCH

      Morning Andrew BMW ISTA/INPA is a program I have loaded onto an old Windows laptop I brought it probably 6 to 8 years ago as an upgrade to the copy of INPA I already owned as an aside the same Laptop has copies of several Diagnostics Mercedes Star Volvo I also have a copy of BMW 1.4.0 on there If you are mounting it on a Laptop I would go for ISTA/INPA cost should be around £100 when buying go for a good supplier offering back up (as always cheapest isnt always best) Your E61 will have around 100 Control ECU's and Sensors ISTA will find and read them all or show them as a Greyed out box. These can be ivestigated and fixed as the program includes Wiring Diagrams Workshop Information with Pictures and Diagrams which obviously are a great help My neibour brought iCarsoft for BMW which has free upgrades (he tells me) I have looked at it and it seems very good but lacks the WIS obviously again a one off cost BMW themselves started to block access to their Technical Information website now subscription only in 2019 they also did the same for their parts website but for cars up to 2019 it is still a great tool. Hope this helps not hinders Dave
