My golf recently started revving on its own when in neutral it will go up to about 1500 then settle back down and keep doing this process over and over, I’ve taken it to the garage and turns out there was a crack in one of the pipes so I’ve had this repaired but the problem is still happening and the exhaust system light has come on. I’ve had it back in the garage and there diagnostics equipment is reading an error with the throttle body so they suggested taking it off and cleaning this part to see if that would fix it but it still hasn’t worked. I just want to know if anyone has had any similar issues and what it turned out to be?
Thanks in advance for any help I get
