Wondering if anyone could advise. I am considering replacing the centre box and pipes with the Supersprint "H" pipes, but keeping the original rear boxes for the moment. Will these EEV's still work or should they be disconnected. Will I have any problems with the ECU generating fault codes.
Also if I replaced the back boxes without the EEV's would the ECU give fault codes. My S6 is a September 2014 model.
Thanks

Assuming you have not removed any cats then there will be no errors codes from an emissions point of view. And if you are leaving the back boxes with their valves in why would you think they would suddenly stop working?
If you buy an exhaust with no valves then the ECU with throw some error codes although there will be no warning on the dash or DIS; you will only notice it when you plug a laptop in. If these codes bother you then buy the Milltek valve delete units which are made for this very reason.
