What control unit is under drivers seat 2005 997s?

Recommended Posts

My convertible got a clogged drain and water got under the seats. The car was taken apart and carpets removed and everything was dried out.

Now the rear wing and the top don't operate and the rear lights stay on.

The independent repair shop software says something is wrong with the rear control unit.

I brought it to the Porsche dealer and they said the rear control unit needs to be replaced.

I thought the alarm control module was under the seat not the rear control unit.

I did some research and it pointed to alarm module under the seat.

What is correct?

In the 997-1 they changed to PAS (alarm/locking) the PAS unit got mounted under the dash near the steering column. The control box under the left-hand seat is the rear control box.

I have had to have this rear control module replaced twice due to water getting into it. Both times the module was fried. The second time, my mechanic drilled holes in the mounting plate so the moisture would not(hopefully) accumulate. I have him clean all the drains at least yearly. Don't ask me where they all are.

The second time, it happened because of a dead battery. The engine box inadvertently got left popped. The battery went dead overnight. With a dead battery, the window will not drop when you close the door and it will not seal properly. It rained and water got in. The entrapped ignition key with a dead battery was an added extra.

The car can behave as if it were posessed when this part goes bad. Flashing lights all over the place, spoiler going up and down, front hood continuously locking and unlocking, horn blowing. The first time, I was out there in my bathrobe in the rain disconnecting the battery.

Interesting you say that a "popped" engine lid made your battery go dead. I have left mine open many times overnight on my 997 Turbo and never had a dead battery. Hmmmm.....

Having this exact problem right now. Drain holes plugged up, water under the drivers seat, and all they issues that MichaelL described.

Just bought the car, and didn't know the drain holes were dirty The car was always garaged....

Any idea what the cost is to replace the rear control module?

I have the same issue. A piece of foam got into the trays and created a perfect drain plug. Anyone know if the Duranetrics system can reprogram a new rear control unit?

I have that issue RIGHT NOW ! 😩😭 I get the drains cleaned by Porsche every year during oil change. But the rain was SO HARD, it think the drain did overflow. I will have to check if they are clean. By then, I'm on my knees with a shopvac in hand 😤
