Citroen Jumper injection system fault

I had a similar problem with my Jumper. Your symptoms sound very familiar. The power was definitely reduced, and it felt like it was using more fuel than usual. Did you check the cable and plug connections?

Thanks. Yes, I checked the cable and plug connections, as I read that these can sometimes cause issues. I didn't find anything obviously wrong, but is there a specific area I should be focusing on?

In my case, the fault was indeed in the cable or plug connection. Although visually everything seemed ok, there was a defective connection to one of the components. If you are unsure, I recommend taking it to a workshop to have it checked. I paid around 95€ for the repair.

Thanks for the advice. I will take it to a workshop to get it checked. Knowing that the cable or plug connection is a likely cause helps. Hopefully, the repair cost will be similar to what you paid.
