Hi together already have the nose full again.. was with my female. my swede no longer runs clean if you want to let it glide nicely undertour through the locality, the speed fluctuates. now wants to expand the row after everything to clean it up. Now a question to you?????? Is it true that each pull off plugs, e.g. air mass knives, elect. throttle flap, leads to a error message. if yes, how can you handle this?????
