Should I de-cobb before visiting dealer ?
Got to take car to Nissan dealer today as there has been a funny rattling noise at the rear for a while, sounds like a loose heat shield or something exhaust related (I hope !!). They said they will ask me to drive a technician around to show him the rattle. Should I just change the map to a low boost map or do you reckon I should remove the cobb maps completely for today ?
I can't believe these guys do a sneaky check by hitting the crusie cancel button to see if it has a cobb map whilst it's in the garage and I can't see it,,,,,,do they ? Am I being paranoid ?
