2015 XF 3.0 sport - just had my oil changed and did the brakes front and rear - pulled into the driveway and engine started idling a bit rough - fine under acceleration. It ran fine for a day and then today I got the engine light so I came home and I plugged in my ICarsoft ODBII scan tool and I get the following four codes -

P2066 - fuel level sensor B
P0505 - Idle Air Contorl

P2189 - too lean at idle bank 2
P2187 - too lean at idle Bank 1

Reading a bit the P2066 is kind of generic code but in combination with these others what would you suggest I test or replace first - I haven't cleared them yet - any ideas?

Thanks in advance

Hey, sorry to dig up this old thread, but I've recently ran into the same issue. Rough idle, P0505 and some other misfire or too lean codes and can't figure out what's wrong. Some say the throttle body sensor, others o2 sensor. Did you find out what caused this issue? I have a 3.0 v6 s/c F-Pace S with the AJ126
