i've read a few topics where some struggle 2 rev their golfs to 5k rpm and it wont go any further,this is then called the safe mode.
i've had exactly the same problem on my golf after i fitted a k&n panelfilter and stripped the throttle body for a good clean.was planning
to give it a go on the motorway,it didn't happen.when stationary the revs was clean and all the way,as soon i started driving it was like a misfire and struggled to get to 5k rpm.parked the golf,checked the mass air meter and all the ding dongs-nothing wrong,then it hit me,what a muppet i is,

forgot to plug the wires back in to the throttle body,after that she was healthy again,and the motorway did see me and i was happy as bugs.

just thought this might shine some light on future safe mode issues.
