Discovery MAF Sensor Symptoms, Fix It Right This Time

Hey there! I had nearly identical issues with my 2014 Land Rover Range Rover Sport (gas engine). The symptoms you're describing match exactly what I experienced, rough running, black smoke, jerking, and that annoying stalling at idle. Got it checked at the garage last month, it was indeed the mass air flow sensor. The mechanic showed me how the sensor was contaminated with dirt and oil particles, which was causing incorrect air-fuel mixture readings. They had to replace the sensor and clean the entire air intake system. It's actually a pretty serious issue since it affects your engine's performance and can lead to more damage if left unfixed. In my case, they also found that the faulty readings had started affecting the oxygen sensors. My advice? Don't delay getting it fixed. These symptoms won't go away on their own and could cause more expensive problems down the line. A qualified mechanic should be able to confirm the diagnosis with a proper scan tool. Good luck with the repair!

Thanks so much for sharing your experience! This is exactly what I needed to hear, I've booked it in for next week based on your advice. Quick question: do you remember roughly how much you paid for the repair? Also, has everything been running smoothly since the fix, or have you noticed any other issues pop up? My Discovery is really my daily driver, so I'm keeping my fingers crossed it's just the MAF sensor and nothing else. Really appreciate your help!

Hey again! Great news, I can definitely put your mind at ease! Since getting the MAF sensor fixed, my Range Rover Sport has been running like a dream. The repair was totally worth it, costing me 415.00 € for the complete fix. That included both the new sensor and the labor for installing it plus cleaning the air intake system. The difference was like night and day, no more black smoke, jerking, or stalling issues. Fuel consumption went back to normal too, which was a huge relief for my wallet! It's been about three months now, and I haven't had a single problem pop up since. For a daily driver like yours, this is definitely something you want sorted properly. The mechanic explained that catching it when we did probably prevented more serious issues down the line. Since you've already booked it in, you're definitely on the right track! Just a heads up, make sure they clean the air intake system while they're at it. It made a real difference in my case. Let us know how it goes after your appointment!

Thanks for all that detailed info! Just got back from the mechanic today and wanted to update you. You were spot on, it was the MAF sensor! The total cost was actually pretty similar to what you paid. The best part? The car's running amazingly now! No more black smoke, jerking, or any of those scary symptoms. They did clean the air intake system like you suggested, and wow, what a difference! The engine feels so much smoother, and I can already tell the fuel consumption has improved. Really appreciate your help with this. It saved me from worrying too much and gave me the confidence to get it sorted quickly. The mechanic even mentioned that catching it early probably prevented more expensive problems down the road. Time to enjoy my Discovery running properly again! Thanks again for sharing your experience, it really helped me make the right decision.
