Seeking Advice on Issues with 2018 Seat Tarraco: Suspected Faulty Intake Air Sensor

Check engine light on

|

Poor fuel economy

|

Unsteady engine

|

Jerking on acceleration

|

Loss of engine power

Hey guys, I’m a bit stressed about my 2018 Seat Tarraco gas guzzler with about 143k on the clock. Recently, I started getting problems like a lit check engine light, engine losing power, it runs pretty uneven, jerks when I speed up, and man does it burn through fuel! From what I can tell, seems like it might be a busted intake air sensor playing up. I’m just hoping my mech isn't taking me for another ride like the last time. Anybody dealt with something similar? What kind of experiences did you have with your mechanic? Your advice is much appreciated!

Hey there, I can totally relate. I own a 2015 Seat Leon and had a similar issue not too long ago. My check engine light had come on, the engine was acting up, and fuel consumption was off the charts. After a bit of panic, I took it to my mechanic. Turned out it was indeed a defective intake air temperature sensor, just like you suspected. Now, let me tell you, without this little guy working properly, the car goes all wonky. It messes up the air-fuel mix, hence the increased fuel consumption, the jerking, and power loss. The process to fix this involved replacing the sensor, and resetting the Engine Control Unit (ECU) for it to start reading the correct values. Then, they ran a few rounds of diagnostics just to make sure everything was sorted. Pretty standard fare, really, not a serious issue or anything. Remember, a good mechanic will explain the issue for you. Mine was pretty upfront about it, laid everything out in layman's terms, which I appreciated. Might do you some good to find one who's not out to make a quick buck. Hope this helps you out!

Hey, you're a lifesaver! This info's giving me some peace of mind. Do you remember how much the damage to your wallet was for getting this sorted? Also, have you had any other issues pop up related to this down the line? Cheers!

Hey, no problem, always happy to help a fellow Seat owner in distress! Now, the moolah part...I don’t have the exact numbers in front of me, but I do remember that fixing the intake air temperature sensor set me back around 155€. It was quite a fair price considering how important this little part is and how it drastically improved my car's performance and fuel efficiency after replacing it. As for your second question, since I've got the sensor issue fixed up by my trusty mechanic, I've had no other problems or complications. Everything's been smooth sailing, no surprises or hidden issues related to it. My Seat's behaving itself just fine now and ironically, I reckon it's even running better than before! Hope this sets your mind at ease!

Hello, that's music to my ears! You've definitely put my worries to rest. 155€ ain't half bad if it means no more stress, and getting my Seat back to its smooth self. Looks like I need to find myself a good, honest mechanic like yours. If there ain't anything else popping up post-fix, it's money well spent. If this is any indication, I think I'm gonna have a better experience this time around. Cheers! You've been a huge help.
