Rough engine running and loss of power in 2014 Toyota Avensis: looking for workshop experience and tips

Hi. Sounds like a similar issue I had recently with my 2017 Toyota Auris, yes, the signs could indicate a faulty fuel pump. On my car it was actually a problem with the software values for the fuel pump. The values were somehow messed up and giving the wrong signals to the pump. The guys at the garage just had to update the software and it ran like a baby again. It was a pretty serious problem because without the correct software values, the pump couldn't work properly. This can damage the engine and drive up fuel consumption. Honestly, it's definitely not a problem to ignore. But don't worry, it wasn't a complicated fix and it looked like they were pretty familiar with it. So complete the diagnosis and get it fixed as soon as possible. Good luck with that!

Hey, thanks for the quick reply and for the valuable information! That sounds really similar to what I'm experiencing with my Avensis right now. Do you happen to remember what the fix cost you at the garage? And has anything else happened since then or has your Auris been running smoothly again since the software update?

Hey, no problem, always happy to help! The garage charged me €45 for the incorrect software values for the fuel pump. Since then, the car has been running great again! I haven't noticed anything conspicuous and the problem with the defective fuel pump really seems to have been fixed. Hopefully you'll get your Avensis running again just as quickly! Good luck!

Great, that's a relief to hear! 45 sounds like a fair price. I also hope that it doesn't get any more complicated with my Toyota. I'll make an appointment at the garage tomorrow and hope for the best. Thanks again for your help, I really appreciate it! Cheers!
