Fiat Doblo 2018 Issues: Black Smoke, Engine Cuts, Jerking Motions, Increased Fuel Consumption and Stalling at Idle

Hey, I totally get what you're experiencing. I had a similar issue with my 2015 Fiat Panda a while back. Engine light on, fuel consumption went through the roof, nasty exhaust smell... you name it. Turned out to be that pesky pressure sensor, just as you suspected. Don't panic though, it was a pretty straightforward fix. My mechanic mentioned that these sensors can be quite finicky, often sending incorrect signals which can throw the whole system out of whack. This causes a lot of the issues you're describing. Last time at the garage they replaced the defective sensor and ran some other tests, just to make sure nothing else was wrong. The car ran smoothly, and the fuel consumption dropped significantly thereafter. Yes, it's a bit of a nuisance but not a serious issue if addressed promptly. Remember to get it seen to as soon as you can though, just to avoid any long term damage to your engine. Happy driving!

Hey there, I feel you, my Doblo gave me quite the grief too. It was the rail pressure sensor messing around just like in your case. Seriously, isn't that just a right pain? Anyway, thanks for the detailed explanation! Do you remember, by any chance, how much the wallet damage was after the mechanics sorted it all out? Plus, did anything else pop up after that or was it all just smooth sailing? Cheers!

Hey, I feel relieved hearing that your Doblo's rail pressure sensor was the culprit, just like mine. Yeah, it's a total bummer but good riddance, right? Well, as for the damage it whipped on my wallet, it was pretty reasonable. I ended up shelling out around 240 bucks to make the sensor behave. After that, my panda purred like a kitten; it was well worth it! No more disasters or nasty surprises. Just my reliable old Panda going smoothly down the road. Let's hope you get the same happy ending with your Doblo. So, shake off those gloves and enjoy the ride!

Cheers for that, it's taken a bit of the worry off my shoulders. I've got to say, hearing that your Panda is up and running, purring like a kitten after the fix gives me a bit of hope. $240 doesn't sound too bad, especially given the state my Doblo's in right now. Let's hope this is the only problem, really don't fancy any more surprises. I'll get onto the mechanic first thing tomorrow. Thanks again for sharing your experience. Appreciate it!
