Hello,
"In my Octavia, manufactured in 2004, with the ATD engine, the following error code is stored: "Fuel pump relay J17 - interruption/short circuit to ground." I have run the Skoda diagnostic program and found no errors. I replaced the fuel pump relay and cleared the error. Initially, everything seemed fine, but after about 120 km, the warning light came on again, with the same error code stored. There are no noticeable issues with the car's performance." I would be very grateful for any help.
