If I get a second hand ignition barrel with key, do I also need the ecu as I have no idea on this?

On my saab I just took old barrel out put new one in with a different key and it started fine and that was immobiliser but I had the old key still on me, so I assume it will still recognise the key?

I have two keys for my car just that the ignition barrel is screwed and need another one.

Thanks all.

The new key will have an immobilizer chip in it so that will need swapping over or re coding but not sure on the ins and outs of it I'm afraid!

Yes, if you still have the key that matches the ECU then code new key in as an additional BEFORE you get rid of the original...

Just easier than having the whole system rematched by "stealer" !!

They may indeed be able to match your existing key to the new barrel :)

      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
