hi people for those who are still interested in this I wanted to submit that you get a performance kit for the d5 at wetterauer, with the following information: 193 ps at 4000 u/min 420 nm at 2000 u/min price incl. installation and 2 years full guarantee without km limitation (so also on motor and transmission!!) : 1042 euro (incl. VAT) ! (price without guarantee and installation : 671 euro) compared to heico but a cheaper variant incl. guarantee. the offer I find rech t interesting and if I had to decide today, I would probably seriously consider this variant.www.mehr-torque.de
