i have a 2004 bmw 545I and i just performed a tune up on it....and i have trouble replacing the closest spark plug to the drivers side....all the way in the back closest to the firewall....i tried to removed the bracket holding down the power wire for the battery boost...but it did not help.....i know on some bimmers the manufacturer created some sort of a hole in the firewall in order to slide the coil out into it....in this case there is no hole....im just wondering if anybody knows a way of removing the coil in order to remove the spark plugs....because i really dont feel like driving on 7 cylinders....and one weaker cylinder....the space between the coil and the firewall is tight...wondering if anyone has any suggestions.....thnx

 

anyone have any suggestions...has anyone done a tune up on there vehicle before?

 

Do a search type in spark plug removal.
