Postovani.Na bmw 116i n45 2004 god.nemam napona na osiguracu 35 fuel pump,pa me zanima ima li taj model relej pumpe goriva?Unaprijed hvala
My bmw is 125i 1series 2001 model so the problem is that there is a power cut and the cluster don’t show up please I need help..not starting but the fuel pump is running
Check the pdc module in the boot its usually behind the right hand aide boot covering in a well , bmw 1 series have an issue with water going in here and filling up the compartment when raining or car wash you may find the pdc module or trailer module or both are sitting in water it affects all things including instrument panel failing to work or flashing off and on and many fault codes appearing , just done it to my partners and was literally sat in 2 inch deep of water,
You can also unplug it to see if it helps as I’m running the car without both modules now and car works perfect again without them , they are mainly for parking distance control and trailer mode for towing but all wired up to the body control module and the instrument panel so causes it all to go faulty
Hello I have a 2008 128I The power to accessories and dash was going on and off intermittently Now the vehicle will not start Not sure where to look I have checked battery connections at battery and in engine compartment Help!!
