Hi all,
I'm new to this forum and I have a question about a rather annoying problem that has developed in my 500.
It's a 2011 500 Lounge, 1.2 petrol, with 56,000 miles on the clock. I bought it second-hand from a private seller in April 2016 (at 52,000 miles). It's had one previous owner, who got all the servicing done at a Fiat dealer.
It's developed an intermittent fault of spluttering/juddering (not sure on the right word here) on acceleration. It's usually when the engine is cold after just starting up (it's just done it very violently tonight in -1C weather). I'll be accelerating, usually on about 2000-2500rpm (it will do it in any gear at any speed) and then it will just start juddering and decelerating quite sharply. It's a difficult one to explain but it's very sharp and causes the car to lose a lot of speed instantly. Luckily, I haven't had anyone too close behind me when it's happened.
But here's what really confuses me about it. Everytime it does this, the Start/Stop disconnected warning light comes on and stays on until the engine is turned off.
I took it to an independent dealer in September and told them about this, but they just took this as meaning it was a problem with the start/stop system. I don't think it is. I'm pretty sure it's to do with the fuel intake, but I'm not certain.
I'm wondering if anyone else has had a similar issue? How do I fix this? It's quite disconcerting when it happens and it needs fixing.
Thanks,
Jake
