Good shout! The fuel economy has definitely taken a hit. So, when you say 'checking the injectors', did you manage to sort it out yourself? Or did you end up going down the workshop route? Did you have to reset anything?

Yeah, fuel economy was a disaster. Honestly, after fiddling around for a bit, I bit the bullet and took it to a workshop. They confirmed it was the injectors and sorted out the 'reset quantity drift compensation' thing. If you're seeing those symptoms, especially with the error code, it might be worth getting it professionally diagnosed. I'm no expert.

Appreciate the advice! I think I'll follow your lead and get it checked out professionally. Just got the quote from the workshop: 515€ for injector replacement and reset. Seems like you were spot on with the injector issue. Thanks again for the help!

I hear you. I had similar symptoms on my Honda Accord, though it's a newer model than yours. Was the fuel economy also tanking? If so, it might be worth checking the injectors. I'm just thinking about a situation I had.
