Mini Cabrio Engine Troubles

Right, I'm at my wit's end with this 2008 Mini Cabrio. It's a model, done about some km. The check engine light is constantly on now, the engine runs really rough, stalls at idle, and it jerks like crazy when I accelerate. Thinking it might be the pressure sensor, maybe the cable or plug? Any ideas before I lose my mind completely?

Sounds familiar. I had a similar issue with my Mini – check engine light, rough idle, the works. It could be the fuel delivery system, maybe a faulty pressure sensor messing with the fuel injector timing and causing engine misfire. Have you checked the sensor's cable and plug connection?

Fuel delivery, eh? Ok, that makes sense. When you had that issue, were the symptoms exactly the same? And did checking the connection solve it for you?

Yep, same symptoms. I tried fiddling with the connector, cleaning it, the usual stuff, but it was a goner. I'd suggest just taking it to a workshop to get it sorted, unless you have the tools to measure the fuel pressure yourself.

Just wanted to give you a heads up. The workshop diagnosed it as a defective fuel pressure sensor, likely some dodgy connection. They replaced it for 95€ and now the Mini runs like a dream again. Thanks for your help!
