I know this has been covered before but probably not together and because I am technically hopeless, I need it all again in simple language. I hope you will bear with me. Simply, my 2011 3.0 old style flappy paddles don't always work (R/H side up changes) so I suspect a loose connection. Given that I also have another BMW with the newer style (+/-) paddles I would like to replace the old with the new set up. Also, I would rather like to fit cruise control. All could be done at the same time by someone competent enough. The questions are then: a) will any 3/5-series etc three stick (wipers/indicator/cruise) column arrangement work if bought s/h off Ebay? Anything I need to look out for other than condition? b) is it possible to retrofit later flappy paddles? c) Again can these be bought s/h and, if so, which cars do I need to select from? and d) is there anyone in the Bristol/Glos area that could install the stuff and re-programme it all accordingly? What sort of price am I looking at here? Is it about £300 all in? TYVM!
