Seeking Advice for 2019 Dacia Logan: Check Engine Light, Decreased Power, Uneven Running and Possible Intake Air Temperature Sensor Issue

Hey! I've got a 2016 Dacia Duster, so we're on the same boat brand-wise. Had an eerily similar situation a while back, check engine light, poor mileages and rocky engine operation, the works. Turns out it was my intake air temperature (IAT) sensor on the fritz, quite like your suspicion. Yes, it was a bit of an issue for me. If the IAT sensor is defective, it can send wrong signals to the car's computer, causing imbalances in the engine's performance. Mine was making my car over consume fuel, dash went a bit nuts and the car was acting sluggish, sort of like you're describing. Quick trip down to my local garage and they went through the whole diagnostics process. End result: busted IAT sensor. Swapped it out for a new one and it was all smooth sailing afterwards. The car was back to its normal self, no power losses, no jerky accelerations and, most importantly, lesser fuel consumption. I can't guarantee that your issue is down to the IAT sensor, but it was in my case. So yeah, take a trip to your garage and share your suspicion about the IAT to them; could save you a bit of trouble. Good luck!

Hey there! Your experience sounds incredibly similar to mine, uncanny really! I'm relieved that swapping out the IAT sensor did the trick for your Duster. If you don't mind, could you jog your memory a bit to recall what kind of dent this whole venture put in your wallet? And since the change, have you faced any other problems or has it been all fine and dandy? Thanks a bunch, appreciate your help!

Hey, it's good to hear back from you! Unsurprisingly, our cars seem to be telling the same tale, huh? Well, regarding the monetary damage, it was pretty reasonable. I had to part with 155€ to get the bloody IAT sensor fixed. I know it's a bit of a hit, but trust me, it was worth every cent considering how swiftly my Duster bounced back. And to answer your second question, ever since that little trip to the grease monkeys, I've had no issues - none at all. The Duster has been just peachy, no more power drops, no more jerks on acceleration, and she's not drinking fuel like a sailor on shore leave anymore. It's all been smooth driving proving that the culprit was indeed that faulty integrating air temperate sensor. I'd say take a deep breath and put your car in the hands of a mechanic. It might just solve all your problems like it did mine. Cheers, and good luck with your car!

Hey there! Thanks for such a detailed response. Your story definitely reassures me that it's worth taking my Logan to the mechanic, despite my past experiences. 155€ doesn't sound too bad if it sorts out all these issues and stops my car chugging fuel like a marathon runner at a water station! I'm really glad to hear that your Duster has been running like a dream since the sensor swap. You've put my mind at ease and given me the push I needed to get my Dacia looked at. Thanks again for sharing your experience – it's been a real help. Wish me luck! Cheers!
