Hi, I am new to the forum and hope someone here can help explain an issue I am having with the fuel Injectors.
In October last year I had a problem with one of the injectors and brought it into BMW. The faulty injector was replaced and all was well.
Fast forward 7 months and I seem to be having misfiring problems.
Once again I bring it into BMW, a different garage and am told there is no problem except that the replaced injector was a newer model with 11, while the other 5 have index 8. Their solution is for me to update the other 5 to index 11.
Seems like a pretty expensive solution to me just to have them all the same index, so I have three questions to those more technical then me (not hard at all)
1. Do I really need them all to be the same index, and if they are not what is likely to happen with the car?
2. Wouldn't it be simpler and cheaper to replace the index 11 unit with an index 8?
3. Should the BMW garage I used originally have made sure they were all the same if its a problem and should I complain about it so?
I hope some of you can help me with this as I really don't want to have to spend so much on the car after paying BMW a lot for servicing and sorting out some other issues.
