Urgent misfire advice please

[G-A-R-Y]

Started up this morning and car is misfiring, tried restarting a few time but still persists. Gone to Euro and bought one coil pack, Question is: how to I identify the bad one. Shall I just change until it stops missing. Diagnostic software is possible but miles away.

They are easy to swap out so id just go with process of elimination!

I'll start now.

No 5 cylinder, job done. Is it worth carrying a spare coil pack @ £15.

 

[fixit man]

I get 3 each of Bosch and HAAS, what's the difference?

Bosch are the original equipment manufacturer that bmw use, I don't know how good the HAAS ones are?

They are guaranteed for a year, same as Bosch.

 

[Scooba_Steve]

But 3 different ones of each?

But 3 different ones of each?

The original bosh ones were redesigned as they were a common failure- I had one go when my car was three years old and the bmw breakdown bloke replace all 6 with newer bosh ones that was around 7 years ago and no issue since. With this car having three of a different brand I suspect at some point they replaced three defective old bosh ones in one go.

 

[G-A-R-Y]

They either work or fail, perhaps the HAAS ones are better than Bosch, only time will tell. I'm just glad it didn't happen on my recent France trip.
Carrying a few tools and spares is wise with an old car???

I mean that show up on ECP when I look, 3 different priced coil packs each of Bosch and HAAS, so 6 in total. Bosch list 2 for the part number on RealOEM and these don't match ECP.
