More Porsche Buying Advice: Boxster Control Module

Another email from Specialist Vehicle Preparations today, with interesting pics of more buying advice: this time on Porsche Boxster.

Having built a number of race cars for the UK Boxster/Porsche Drivers’ Championship and achieving 100% reliability on those built to date, SVP Porsche is especially fond of the 986/987 Boxster.

Reliability took a 2001 Boxster S race car built for Cool Cava Racing in the Porsche Sports Cup Scandinavia to overall second last year, despite a few offs and rookie driver Pal Krogdahl having the distraction of a house move, halfway through the season. The car built for Dave Hughes Racing had Hughes leading the championship in the middle of his rookie year, again thanks to reliability. If your car finishes when others do not, you just keep picking up the points.

Servicing and sorting road car issues is perfect training for what makes Boxsters fail. One big problem on 986 Boxsters is the immobiliser module under the seat getting wet from water ingress and blocked up drains in the hood box. Porsche almost sorted that for 987, but then hit the land of fail. SVP’s Dom Delaney tells all:

“986 Boxsters suffer with the immobiliser under the seat getting wet. Porsche solved that on the 987 by moving it into the boot. Trouble is, they put the rear end control unit under the seat instead, and when that gets ruined it tries to operate the roof. Because it’s locked, that breaks the mechanism. So, not only do you need a new ECU, you also need to fix the roof. ”

The picture above shows the rear end ECU from a mint condition 2009 Porsche Boxster with just 20k miles on the clock. The floor under the carpet is apparently full of mud. SVP’s solution is to repair the control modules if not gone too far, replace the floor bungs, clear rear drains and bulkhead drains and generally dry them out. Delaney has a heads-up for new Boxster buyers:

“The latest Boxster doesnt have a manual lock mechanism on the roof, so if controller is in same place and gets wet, roof will be open on its own. Next morning when you come out and get in your car…” Have you had this or similar problems? Let us know in the comments!
