My mechanic tells me that he has to replace the 6 ignition coils in my 1998 BMW 528i - he wants $800 to do it. I can get new coils online for about $30 each, and it seems to me that I could put them in myself within an hour. Am I unaware of some kind of special tuning, knowledge, or tools that would be required, or can I venture into this apparently simple DIY project without worry?

Also, OEM coils replacements are $70, which is still only $420 - so the additional $380 is what has me wondering.

  • 380 for install, setup and testing by a BMW garage? Seems perfectly reasonable.

  • Anything under a grand always feels reasonable, lol...just wondering if this is something I could do to save the 500 so that I can afford his christmas bonus!

  • Why does he want to replace all of them? Doesn't seem likely that all 6 are bad. What symptoms are you having?

IF you have an E39 with an M54 engine, it is as easy as:

  1. Unplugging Battery
  2. Unplug cable, and possibly unscrew rail
  3. Unscrew each coil pack, and replace
  4. Reconnect all items, and test drive

Not a very hard job, as all the packs are exposed once you remove the cover.

  • The 1998 apparently has the M52 engine: en.wikipedia.org/wiki/BMW_M52#M52B28
