Start Problem

Recommended Posts

Dear Forum I have a 99 Boxster Triptronic. Sometimes when I try and start the car the key just turns to the start position but nothing happens. It is like the car is in gear. I can wiggle the shifter back and forth and then place it in neutral and it starts. Other times it starts just fine. I was told it was likely a switch that is connected to the shifter or shift linkage on the transmission and the swith can be cleaned or adjusted. Can anyone advise if the starter interlock switch is under the center console or on the back of the transmission. If it is on the trans, can it be accessed by jacking the car up or does this job require a lift. Thank you, Jerry

Hi There,

Not sure if this is the part you are referring to, but this is the Tiptronic Selector Switch and is on the transmission. Hope this helps. Included a diagram for you. Part number is 986 325 612 01 for a 99 Boxster.

I would assume this would indicate the position (gear) of the selector and if it sensed it was not in Park/Neutral would not allow starter to turn over?

Also included a diagram of the Tiptronic shifter components in case thathelps?

Good luck!
