BMW 1 Series Rough Start and Stalling: Bad Injectors?

Hey there! I had nearly identical issues with my 2011 BMW 2 Series last year. The symptoms you're describing match what I experienced, rough idle, hard starts, excessive fuel consumption, and poor performance. After seeing these signs, I took my car to the garage, and the diagnosis confirmed dirty fuel injectors. Carbon deposits had built up over time, clogging the injectors. The fix involved removing and professionally cleaning all injectors, plus replacing two that were beyond repair. It's a fairly serious issue since faulty injectors can lead to more severe engine problems if left untreated. In my case, it took about a day to complete the repair. The car's performance improved dramatically afterward, smooth idle, better fuel economy, and proper startup. To avoid this in the future, the mechanic recommended using quality fuel and getting injector cleaning service during regular maintenance intervals. Hope this helps with your decision! Best regards

Hey again! Thanks for sharing your experience, it's really helpful to know I'm not alone with these injector troubles! The symptoms you described are spot on with what I'm experiencing. Quick question though, do you remember roughly how much you ended up paying for the whole repair? Also, has everything been running smoothly since the fix, or have you noticed any other issues pop up? Thanks!

Hey! Happy to give you the update! After my repair, I paid 515 € to get the faulty injection nozzle fixed. They found one injection valve was totally clogged up with dirt and debris. Got it sorted, and honestly, it was worth every penny. Since the repair, my BMW's been running like a dream, it's like having a completely different car! No more of those annoying starting problems or that horrible rough idle. Fuel consumption is back to normal too, which is saving me some decent money at the pump. Haven't had a single issue pop up since then. The mechanic did a thorough job, and I'm keeping up with regular maintenance to prevent it from happening again. If your symptoms are similar to what I had, I'd definitely recommend getting those injectors checked out sooner rather than later. It's not worth risking more serious engine damage by waiting too long. Let me know if you need any other info! Always happy to help out a fellow BMW owner. Cheers!

Thanks so much for all the detailed info! I actually took your advice and got my car checked out yesterday. What a relief, turns out it was definitely the injectors, just like you said. Had to shell out about 600 € for the whole job, a bit more than yours since they found two injectors that needed replacing. The mechanic I found was really thorough and explained everything clearly. Got to say, the difference is incredible! My car starts up perfectly now, runs super smooth, and that annoying rough idle is completely gone. Can't believe I waited so long to get it fixed. Really appreciate you sharing your experience, it gave me the push I needed to get this sorted. Definitely learned my lesson about regular maintenance too. Going to keep a much closer eye on things from now on. Thanks again for all your help! Cheers!

Hello. I have a problem with a 2011 BMW 3 Series 320i e90. Cylinder number three has a problem even though I have changed the spark plugs, coil, and injector. The car continues to shake and the error code it is now receiving is 2e32

(Translated from French)

Check the wiring and connectors for cylinder number three to ensure there are no loose connections or damaged wires. A faulty connection can cause misfires even if the components themselves are in good condition. If the wiring looks fine, consider performing a compression test on cylinder three to rule out any mechanical issues like a valve or piston problem. Let me know how it goes or if you have any further questions!
