I'd definitely take the self amalgamating tape, as suggested by Baltic Blue.

That is always in my car, gives a great repair if a coolant hose fails. Has got me out of a hole more than once (BMW M62 V8 engine coolant hoses love to go pop) There's a kit you can buy, which basically has two rolls of tape, one to reinforce the repair and then the amalgamating tape goes on top of that -> Highly recommended!

Also pack some spare fuses, bulbs, first aid kit, as well as basic tools (common sized sockets & spanners, screwdrivers), as well as an LED lantern for night (think changing a wheel in the dark)!

Don't forget an oversized socket in case your wheel nuts have swollen (23mm required instead of 22mm ), a common cause of frustration when trying to change a wheel!

I was scratching my head for a moment on what an FSR was (despite having changed one!) It's the Final Stage Resistor, or blower motor resistor (AKA Hedgehog resistor) - often a culprit of a battery that drains overnight.

Decent sized tie wraps can get you out of all sorts of issues, as well as the obligatory roll of Gaffa tape!

A candle's heat in the cabin will save your life if it's freezing cold, and chocolate in the glove box and drinking water are always welcome supplies if you get stranded for any length of time.

Most of all though, don't forget the baby wipes - invaluable for all manner of uses! Oh, and European breakdown insurance.

Have a safe trip,
