2021 Renault Arkana Showing Signs of Engine Trouble: Potential Tank Ventilation System Leak

Hey! Totally understand where you're coming from. I have a 2018 Renault Kadjar and had something almost identical going on. Same symptoms - check engine light, shaky engine, problems with acceleration and stalling at idle. After a bit of head-scratching, it turned out the culprit was a defective activated carbon filter (also known as charcoal canister). This little bugger is part of the emission control system and collects fuel vapors from the fuel tank preventing them from escaping into the atmosphere. When it fails, you might see symptoms like you're experiencing. It was a bit of a nuisance, but not too severe - the car was still drivable. As for the garage, it was a more positive experience than I'd anticipated. To be honest, I was pretty skeptical too after my previous bad experiences. They diagnosed the issue promptly and looked after the car well while replacing the filter. Took a few hours to fix, but it totally sorted out the problem. Hope this helps, and let us know how it goes.

Hey there! Your story sounds pretty familiar to me. My Renault Arkana had similar problems a few months back. Engine trouble, stalling at idle, the whole shebang. The mechanic also pointed fingers at the activated carbon filter, as in your case. Your experience with the garage sounds a whole lot better than mine, though. Good to know some professional and decent ones are out there. Just curious, do you recall how much it cost to replace that charcoal canister? And has anything else problematic cropped up since the fix? Appreciate all the info.

Hey there! Yeah, I distinctly recall the cost of the repair. It was a bit of pocket pinch, you know - shelled out 275€ to have that blasted activated carbon filter replaced. But hey, once they sorted that out, no more engine seizures or shaking, so worth every penny if you ask me. And after they fixed the leak in the tank ventilation system since the last visit to the mechanic, it's been smooth sailing (or should I say driving)! So that's one fewer thing to fret about, at least. Hope that clears up your queries, bud, let us know how you get on with your Arkana!

Hey! I'm relieved to hear your Arkana's been purring along smoothly post-fix! €275 does sound like a fair bit, but like you said, guess it's worth it if it eases out all the dodgy stallings and shaking. I'm definitely now considering getting mine checked, though hoping the local guys over here won't be as rough as last time. Thanks for the heads up! Let's hope my Arkana's road to recovery is as smooth as yours was. Cheers!
