5 Series Fuel Filter Replacement
Hi First time poster,
My car recently failed MOT on emissions, first advice was to service the fuel filter and replace. I have a new fuel filter and swapping out seems pretty straight forward. Just one concern, do I need to bleed the fuel system using Ista or can I just swap it out and put the new one in. I've seen some people recommend stating ignition a few times before fully starting the car up to the get the fuel pump to refill the system, any views? It's 2012 diesel 520. Follow up question if I need to use Ista where would I down load it and which cable should I purchase to connect to the OBD port? Thank you for any help or advise. Colin |

The official ISTA instructions do not mention activating the fuel pump after filter replacement, but indeed many people advise either forcing the fuel pump on in ISTA or cycling ignition a few times before starting the engine. Given all issues with the Bosch HPFP on these cars I'd follow that advice even if placebo :-)
