im suspecting the gearbox brain circuit board is playing up in my 997.1. Anyone know where I can source one?

Hello Lee
Think we're going to need more info here.
What is the fault & fault code?
Proper diagnosis needed or you'll gradually replace parts till fault is fixed.

Assume its a tip - if so, its a MB unit, so plenty of parts and knowledge there.

Hi Jonno,

Couple of months back I gave it a large amount of right foot while right hand round a roundabout, the gear indicator started alternating between D & N car went into limp mode and warning came up in main instrument showing a red rectangle box with two circles in it with the warning triptronic overrun.

After turning off and restarting fault cleared, although I did replicate the fault out of curiosity?

It’s behaved since ( although I’m not sure I’ve put it under the same stress since)!

week or two ago while on a road trip of a few hundreds miles on a very hot day, I accelerated heavily and the gear indicator went out (no gear selected) I immediately dropped the throttle waited a few seconds and it found gear again.

I’ve discussed with a local Indi, who recon it’s the contacts on the circuit board work loose after time and replacing the board would fix it! Although after trying they state porsche no longer sell the board but will look around for me?

Lee.

Do you have the part number or a description of the part?

I can give a guy a ring on Monday morning to see if he has one.

I’m just taking it from what my local indi told me re- there being a board in the box (from underneath the car) it’s above the solenoid tray, apparently known for this error and causing problems. The contacts work loose?

Not seen it or had it out, can’t find a listing on regular parts sites?
