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. –  Rory Alsop Jul 1 '12 at 20:42
    
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! –  GDP Jul 1 '12 at 23:45
    
Why does he want to replace all of them? Doesn't seem likely that all 6 are bad. What symptoms are you having? –  Larry Jul 5 '12 at 18:43

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 –  Bob Cross Jul 5 '12 at 12:04
    
Have done the plugs, and simple stuff....it looked easy enough, but I just didn't know if there was some magic with new ones...thanks you good people! :) –  GDP Jul 5 '12 at 12:50
