Where is Litronics control module physically located?
I’ve searched online and cannot find the physical location on the car of the Litronics control module (99661815115). Can someone please tell me its location?
My factory Litronics are not self leveling and my Durametric points to the control module. My chassis sensors are connected and properly oriented. Both headlights respond properly to Durametric orientation commands. If I erase the fault codes they return immediately. Want to start problem determination by ensuring that the control module is properly plugged in.
Thanks in advance!

Had codes 1 & 2 myself. passenger side seat, right below the airbag is the module. Have to remove the duct to get to it. On mine it was connected but 1 of the pins has backed out. Was a pain to get to but once I did codes went away and lights stopped going to only low.

Thanks Stl. I purchased an e-service manual yesterday that indicated the location you specified but for my 2004 the module is in the frunk under the right side liner. Porsche must have moved it when they added the glove box. Much easier to get to than the under the dash location.
I checked the pins and reseated the plug but lights are still not leveling. I’ll update as soon as I have time to do more problem determination.

The leveling control is mounted on the Left rear control arm, If litronic's are not oe you need to buy & retrofit the leveling control.

There are actually 2. Both left side on front & rear control arms. The arms usually break but those would only be codes 3 & 4. All those codes indicate a control module issue, wiring to it or fuse.
