Hi everyone

I’ve got myself a 3.0 325i and I’ve started to get misfires twice in the last 4 months of ownership, I’m expecting an injector issue as the car has a constant jerk on idle.

I rang up a specialist who told me that I couldn’t get away with just replacing one the faulty injector as all 6 need to be index11. Is this true or is it safe to mix indices (9&11 for example)

Ideally I’d be really happy if I could just replace the faulty ones as current prices on injectors are through the roof and if I were to buy them brand new I’d almost pay exactly the same as what I’ve paid for the car

Any advice would be of great help

Thanks
Hari
