BMW XM Fuel Injection Nightmare, Help Needed

Hey there! I had nearly identical symptoms with my 2020 BMW X6 M last year. The rough idle, excessive fuel consumption, and power loss were exactly what I experienced. After diagnostic tests, it turned out the fuel injectors were seriously clogged with carbon deposits. The repair involved removing and ultrasonic cleaning of all injectors, plus replacing two that were beyond salvaging. The job took two full days at the shop. This wasn't a minor issue, dirty injectors can lead to more severe engine damage if left untreated. Since the repair, my X6 M has been running smoothly with proper fuel economy restored. The emissions are back to normal too. If you're experiencing these symptoms, I'd strongly recommend getting it checked soon to prevent potential engine damage. Just make sure to find a shop that specializes in BMW fuel injection systems. They'll need specific diagnostic tools and expertise for these engines.

Thanks for sharing your experience! That's really helpful since it sounds exactly like what I'm dealing with. I'm relieved to hear you got it sorted out. Been worried about potential engine damage, so knowing you fixed a similar issue gives me some hope. Just curious, do you remember roughly how much the whole injector cleaning and replacement set you back? Also, has everything stayed running smoothly since the repair, or have you noticed any other issues pop up? Thanks again!

Happy to help with more details! Yeah, after getting my X6 M fixed, it's been running like a dream. I had it repaired about six months ago, the shop found a defective injection nozzle and some serious gunk buildup. Total bill came to 515 € for the injection valve cleaning and replacement. Worth every penny though! Since the repair, my ride's been performing perfectly, no more rough starts, better fuel economy, and the power's back to what it should be. The emissions are spot-on now too. It's such a relief not hearing that rough idle anymore or watching the fuel gauge drop like crazy. I'd definitely say don't wait around on getting yours checked. These high-performance engines are pretty sensitive to injection problems, and catching it early saved me from bigger headaches. Once you get it sorted, you'll notice the difference right away, trust me! Let me know if you need any other info about the repair. Always happy to help another BMW owner out!

Just wanted to update you, I took your advice and finally got my XM checked out. You were totally right about the injector issues! Took it to a specialized BMW shop and they found two completely clogged injectors plus a bunch of carbon buildup in the others. The bill was a bit steeper than yours, ended up paying around 700 € since they had to replace both injectors completely. But wow, what a difference! The engine runs so smooth now, starts up instantly, and my fuel consumption is back to normal. Such a relief not having to worry about stalling at every stoplight anymore. They also gave me some tips about using better quality fuel and regular maintenance to prevent future buildup. Really glad I didn't wait any longer, the mechanic said I could've faced some serious engine damage if I'd kept driving it like that. Thanks again for sharing your experience, it gave me the push I needed to get it sorted!
