BMW i3 Hybrid Stalling: Fix Injection System Now

Hey there! I had similar issues with my 2017 BMW i8 Hybrid last summer. The symptoms you're describing sound exactly like what I experienced, jerking, stalling, excessive fuel consumption, and that annoying smoke. After taking it to the garage, turned out the fuel injector wiring harness had deteriorated, causing poor connections and misfiring. The connector pins were corroded, and two injectors weren't getting proper signals. This is actually a serious issue that can damage your engine if left unchecked. The mechanic had to replace the wiring harness and clean the injector ports. They also found that the electronic control unit needed a software update to properly manage the hybrid system. After the fix, the car ran smooth again, no more jerking or smoke. Based on your symptoms, I'd bet you're dealing with something similar. Don't wait too long to get it checked out. These hybrid systems are quite complex and need specialized attention. Best

Hey! Thanks so much for sharing your experience! Your i8 problems sound identical to what I'm dealing with right now. Really good to know about the wiring harness, makes total sense with all these symptoms. Could you remember roughly how much the whole repair set you back? Also, just curious, have you had any other issues pop up since getting it fixed?

Glad I could help! Yeah, I actually just got my i8 back from the mechanic last week for this exact issue. Good news, it's running like a dream now! The injection system fault was exactly what we thought, and it was a much simpler fix than I initially feared. They just needed to repair a faulty cable connection, which was causing all those annoying symptoms. The total bill came to 95 € for the repair, which was a relief considering I was bracing myself for much worse! Since the fix, my car's been performing perfectly, no more jerking, no smoke, and fuel consumption is back to normal. Such a night and day difference! Haven't had any other issues pop up since then, and it's been super smooth sailing. The engine's got its power back and runs quiet like it should. Honestly wish I'd gotten it sorted sooner instead of worrying about it for so long. Hope this helps with your decision! Let me know how you get on with yours. Best

Hey! Just wanted to give you an update! Finally got my i3 checked out yesterday, and you were spot on about getting it fixed sooner. Turns out my problem was pretty similar, but I also had a clogged fuel filter making things worse. The mechanic I found was actually great, super transparent about everything. Total cost was higher than yours at 280 € because of the extra parts, but honestly, seeing how the car runs now, it was worth every penny. No more jerking, smoking, or that awful feeling every time I start the engine! Funny thing, while I was there, the mechanic showed me the old filter and wiring. They were in such bad shape, I'm amazed the car was running at all! Really glad I didn't wait any longer to get it sorted. Thanks again for pushing me to get it checked out. You really helped me dodge a bullet there!
