Hi weegogs,
Good to hear that my P1502 fix is still helping people get their Y2K Boxster's working again!
It's strange that it seems to be specific to that model year - perhaps Porsche spotted an issue and re-engineered a component early in 2001?
As mentioned in my original
www.renntech.org post, the P1502 limp mode issue was nothing to do with the:
- Throttle Body
- MAF sensor
- DME
- Wiring loom
I'm not convinced that it was a relay or battery issue either (although I changed both shortly afterwards).
I can't give a 100% guarantee, but my view is that the root cause was a worn and faulty ignition switch.
The electrical switch can be replaced for about £20-£30.
It's used by VAG on Audi, VW, Porsche and Skoda cars and the part number is 4A0905849B.
You don't need to pay Porsche prices for a genuine part, but I'd get an OEM part rather than one of the cheaper copies.
You don't need to change the ignition lock barrel, just the ignition switch.
I'd buy a couple if you plan to keep the car for a while.
I'm about to change the switch again (12 years later) as it's less 'clicky' and is starting to feel loose and worn out.
Cheers,
Nick.
