I've always been asked to provide the DVLA thingie (for all drivers) - which provides a one-time code that they can look up for validity of license / convictions etc. From memory there is a big excess (which is usually covered by your insurance company - given that you aren't driving your own car whilst it sits at Tesla) - but you might want to check that normally it is "any loaner that Dealer provides", but worth checking in case Tesla give you an MS-P and yours is an M3SR , and £100 a day charge it you cannot pick up promptly once the work is completed.
