Dash panel insert for vehicles 1998 ? > < Checking voltages and bulbs with test box V.A.G 1598

Test prerequisites:

Test prerequisites:

t	Battery voltage OK

t	Affected fuses OK (see current flow diagram)

t	Hand-held multimeter: set to voltage measurement -V-

Note

t	In case of deviation from specification, check wiring harness according to current flow diagram.

t	If specification is reached during test steps 1 and 2, dash panel insert must be renewed.

t	If specification is reached during test steps 3 and 9, respective bulb must be checked. Dash panel insert must only be renewed when bulb is OK.

Test step	-V.A.G 1598- Bushes	The voltage supply is tested	Test conditions and additional work	Specifications
1	11 + 3	Terminal 30/terminal 31	Ignition switched off	Approx. battery voltage
2	13 + 3	Terminal 15/terminal 31	Ignition switched on	Approx. battery voltage
3 → Note	22 + 3	Left turn signal warning lamp	Ignition switched on Connect test lamp Switch on left turn signal	Test lamp flashes
4 → Note	24 + 3	Right turn signal warning lamp	Ignition switched on Connect test lamp Switch on right turn signal	Test lamp flashes

¹⁾	Use -V.A.G 1527- test lamp.

Test step	-V.A.G 1598- Bushes	The voltage supply is tested	Test conditions and additional work	Specifications
5	12 + 3	Bulbs for illumination of dash panel insert, digital clock MFI and distance display	Ignition switched on Switch on light switch	Approx. 2.5 V to battery voltage, depending on position of controller E20
6	25 + 3	Main beam warning lamp	Ignition switched on Switch on main beam	Approx. battery voltage
7	18 + 3	Twin circuit brakes and handbrake system warning lamp	Ignition switched on Apply handbrake Release handbrake	Approx. 0 V approx. battery voltage
8	16 + 3	Warning lamp for alternator	Ignition switched on Start engine	Approx. battery voltage
9 → Note	13 + 20	Glow period indicator lamp	Engine cold (below glow temperature) Switch on ignition	Approx. battery voltage until glow temperature is attained

²⁾	Only for diesel engine and not when engine is hot
