Crookedaxle 0 #1 Posted September 6 (edited) Is there a way to verify if it's something other than a dead coil before having to pull engine shrouding? I'm assuming both coils have a grounding wire on them too, or maybe not with DSAM? Do you have to pull shrouding to get to the grounding wires (if they exist)? Any other ideas? I believe I have DSAM because there is a rectangular box on the shroud. It's a 1998 model. I also have a 518xi and 520xi that are both 1998's too and they both have no rectangular box on the shrouding. Here's the engine tag for the 1998 522xi: Edited September 7 by Crookedaxle Share this post Link to post Share on other sites

JoeM 8,580 #5 Posted September 7 If you got the black box, it's a smart spark. I have seen different ways to get at the wiring but I just bite the bullet and pull the engine. It is a 45 minute job if you have a way to lift it out. There is a kit to convert the system over to standard ignition and it includes a flywheel. I have done two. One I changed the flywheel with the kit, the other I just used two new coils. Some have said using just the new coils (because the flywheel key is a few degrees different) makes it hard to start because of the timing being advanced. I did not notice any issue just changing over the coils and eliminating the smart spark. While the engine is out it is a good time to check the rear seal and change it if necessary. Also good time to clean up the charging stator this is the kit I used. 1 Share this post Link to post Share on other sites
