Potential Faulty Tank Vent Valve causing Performance Issues in 2018 Seat Tarraco

Hey there! Sounds like you're having quite the time with your Tarraco. I've got a 2015 Seat Ibiza myself, and a while back it started giving me grief, a bit like what you're describing. Turns out, it was to do with some extra hoses that had been added on my own car, if you believe it. Like, additional hoses were set up wrong or clamped incorrectly which, in turn, impacted the car's overall performance. Was this a serious issue? Well, yeah! Aside from the obvious discomfort of driving like that, it was messing up a whole bunch of systems underneath the hood that I wouldn't want to breakdown. So, I bit the bullet and got her down to the garage - though with some good knowledge backup, like you're after, smart move! They figured out the problem, sorted the hoses, clamps, and the tank vent valve—mechanics' voodoo for all I know. She cruised much better afterward, and those weird quirks I'd been seeing? All gone, and hasn't bothered me since. Hope this helps you out. Best to arm yourself with a bit of info and then trust the experts. Good luck!

Hey, thanks for the response! Your situation with the Ibiza sounds eerily similar. And honestly, it’s a bit of a relief to know I’m not alone in dealing with these pesky car problems. I reckon I'll do what you did - do a bit more homework and then take my Tarraco down to the pros. Just curious though, can you recall how much the repair work cost you at the garage? Also, have any other issues popped up since then? Always nice to know if I should brace for more in the near future. Thanks again for the advice!

Hey no problem, happy to help! I hear your concerns about the costs, trust me, been there. For my Ibiza, the mechanics took care of the tank vent valve fault that was causing me trouble and the cost was manageable. The extra hoses that got added to my car, now, that was a bit more costly, gave my pocket a hit of 175€. But hey, totally worth it to see my car running smoothly again and not acting like a space shuttle countdown. It's been smooth sailing since the fix, no additional problems or issues popped up - thank goodness! Ideally, your Tarraco should be all good after getting the tank vent valve checked out, assuming it's a similar case. Best of luck! Here's to a trouble-free drive thereafter!

Thanks again for the help and the info! Sounds like it was money well spent to get your Ibiza back on track. Anyway, giving my wallet a hit for a smooth drive is way better than dealing with the annoying car troubles every day, right? Time to roll the dice and take my Tarraco to see the mechanic with a bit more knowledge under my belt. Fingers crossed it's just the tank vent valve acting up. Really appreciate your words! Here's to hoping my experience ends with a trouble-free drive as well! Cheers!
