Volkswagen New Beetle. Manual - part 283

Some functions which could previously be performed with V.A.G 1551/1552 must now be performed with the 
Vehicle Diagnosis, Testing and Information System VAS 5051 in the operating mode vehicle On Board 
Diagnosis (OBD): See Operating instructions for Vehicle Diagnosis, Testing and Information System VAS 
5051. 

The malfunction information displayed is used to refer to the Diagnostic Trouble Code (DTC) table with notes 
on the possible causes for directed repair measures. 

Malfunctions which can be attributed to a temporary open circuit in the wiring or a loose contact (terminal), will 
also be stored. These malfunctions will be displayed as sporadic malfunctions "SP".

The breakdown of the display content illustrated on BREAK DOWN OF DISPLAY CONTENT FOR 
DISPLAY GROUP NUMBER 015 for the display group number 15 gives information as to which component 
triggered the alarm system last, and can therefore help the fault finding/repair.

The interior monitoring system is a component part of the anti-theft alarm system. The system is comprised of 
two sensors which are installed in place of the rear reading lights. The reading light function is integrated in the 
component and operating the light is separate function on each of the two sensors. 

The monitoring of the interior works on the ultrasonic principle. If the armed system detects movement in the 
vehicle then an alarm is raised via the anti-theft alarm system (ATA). 

The interior monitoring sensors can be switched off via a button in the B pillar/door sill and using the adaption 
function (function 10, channel number 05). To do this the ignition key must be removed from the ignition lock 
after switching off the ignition then press the button and lock the vehicle. 

When the vehicle is next unlocked the sensors are reactivated 

For technical reasons one must wait at least 30 seconds when the vehicle is locked for all test possibilities.
