I have sometimes this problem:

The engine coughs for a long time before starting ...

I don't understand why, because, sometimes, with the same cold weather and cold engine, it starts very fast. How can that starting time vary so much ?

  • Are you allowing the glow plugs to warm the combustion chambers prior to try to start it? – Pᴀᴜʟsᴛᴇʀ2♦ Jan 29 '14 at 12:21

The problem could be that the glow plug relay is going out. If it is intermittent, the glow plugs will heat sometimes and other times not. I don't know if this is a known issue with BMW diesels, but it is plausible this is your issue.
