C30 injector problems
Summary of the thread
A 2010 Volvo C30 is experiencing symptoms indicative of defective injection nozzles, such as poor starting, high fuel consumption, reduced power, uneven idling, and stalling. The suspected cause is a dirty injection valve, confirmed by the presence of misfires and a rich-smelling exhaust. Replacing the injectors resolved similar issues for another owner, and a workshop confirmed the injector problem, leading to a planned replacement.

Misfires present. Exhaust smells rich. Did replacing the injectors solve your issue?

Yeah, replacing the injectors sorted it completely. Given your symptoms, I'd bet that's your problem too. I ended up taking it to a workshop though, needed some special tools.

Thanks, I appreciate the confirmation. Workshop confirmed injector issue. Repair cost 515€. Time to replace them.

Sounds familiar! I had a similar issue with my C30, same symptoms. Did you check for misfires? How does the exhaust smell?
