I have a 64 plates Golf SV SE spec 1.4 TSI DSG. I am looking to upgrade the front seats to give better lumber support, having had sciatica for a number of years. I recently had use of a Passat R Line with full heated seat with air bag lumber support and it was spot on. However the Passat seat will not fit the Golf and the Golf R Line does not have air lumber support. Recaro make an orthopead seat but at present do not make a seat base to fit their seat into a Golf SV. Has anybody done an upgrade on Golf SV or MK7 seats or have any ideas.

I am going to have front & rear sensors fitted. Would prefer to have them indicating through the multi function display. OEM RETROFITS of Bradford fit a system that does what I am looking for but they only have mobile engineers and a bit pricey at £600 ish. They claim their system is VW original factory fit components. Anybody used them?
Any info or advice on the above will be appreciated.
