If, like me, you are not mechanically gifted there is limited value in carrying spares. If it's peace of mind you are after, don't forget you can easily extend the car's parts and labour warranty by getting insurance. I found this invaluable on my first M3W which was a 2013 model prone to early faults. It was sold to me by a dealer after the MMC warranty had expired - so they simply added a 1 year warranty policy from Centurion which later covered the costs of replacing the regulator and oil pressure sensor which soon packed up. I was quoted £120 to extend for another year...(less than the cost of the regulator)
So my spares kit is:
1.) European breakdown and recovery (I can recommend Startrescue who have recovered me twice in one year so far - once from France and last week from Land's End - good value for £50 annual premium)
2.) Mobile phone and car charger
3.)an extended car warranty (which I will take out once my 3 yr MMC warranty has expired)
4.) A laminated card with the phone numbers for recovery/warranty and "Do not tow this car" translated into French/German etc as your itinerary requires - to keep in your wallet
5.) An umbrella to keep you dry as you wait in the rain for recovery - and help maintain a suitably eccentric demeanour
Alternatively, as Ian suggests, travel in the company of other Mog owners and be amazed at what they know and can fix!
