2008 997 GT3 Headlight Angle Error

Recommended Posts

Hi,

I've a 2008 997 GT3 that has a headlight adjustment error on the dash, and through the PIWIS diagnostics I have an 8033 Compression Angle Sensor (Rear) error. Indeed the Actual Values of the rear sensor is 0.00V. However, the car physically does not have suspension height angle sensors on the lower arms either front or rear, similar to the Carerra models, even though the PET catalog seems to indicate that it does. So hence, the puzzlement of this problem.

I have been told that there are level sensors in the control unit for the Litronics, but I can't find anything conclusive. I do know that the 996 GT3 had levelling sensing control units under the headlight.

How does it measure the suspension angles without the sensors on the arms?

Check to see if you have a sensor on the rear driver side suspension. Its usually a small black plastic box with a long plastic rod that swivels off one side and connects to the A-arms. Its common for them to break where the rod connects to the suspension. Which would cause the headlights to adjust out of normal range and may cause the code.

I checked and there is no sensor on either the Rear or the Front suspension. I checked, re-checked and triple-checked! I'm very familiar with the sensors that you are referring to, but they are non-existent on this car.

Front body computer says Rear Sensor error and Actual Values show 0.00V from that sensor. But the question, where is the sensor? Could it be that the GT3's don't use the lever arm angle sensor on the arms like the Carrera's do? If they don't then is it in a levelling ECU somewhere?

I checked a different GT3 today, and it seems that the GT3 does not have this sensor like the Carrera models.

Does anyone know where the sensors for suspension compression are for a GT3?

I was wondering if I could move this discussion to the GT3 section of the forum.
