i have been wanting to complete a few mods on my 2005 (September) 2.0TDi S Line A4 over the last few months and have finally decided to try and sort them out. i have just had 4 Vredestein Ultrac Sessanta tyres fitted am getting round to sorting cruise control and 6000k HiD lights in my dims and fogs. One thing i have always wanted though and really would like to get is a multi-function steering wheel. but what exactly do i need?! i have read that some people have had awful problems trying to get this to work. if i bought the shell of a 2006 MFSW and used my current airbag, will this work once programmed? plug and play?! or do i need other items to get it going. any advice appreciated!
