Work instruction			Display OK	If not OK
1	Check wiring between oil level sender and instrument cluster for short to B+	Switch off ignition Disconnect plug B from the instrument cluster Pull off plug on sensor for oil level indicator Switch on ignition Measure voltage between plug B on instrument cluster pin 2 and ground Measure voltage between plug B on instrument cluster pin 18 and ground	0 V Step 2	Repair wiring harness ->End
2	Check wire between oil level sender and instrument cluster for short to ground	Switch off ignition Measure resistance between plug B on instrument cluster pin 2 and ground Measure resistance between plug B on instrument cluster pin 18 and ground	Step 3	Repair wiring harness ->End
3	Check wiring between sensor for oil level indicator and instrument cluster for open circuit	Switch off ignition Measure resistance between plug B on the instrument cluster pin 2 and plug on oil level sender pin 2 Measure resistance between plug B on the instrument cluster pin 18 and plug on the sensor for oil pressure indicator, pin 4	< 5 Step 4	Repair wiring harness. ->End
4	Check sensor for oil level indicator	Switch off ignition Connect plug to sensor for oil level indicator again Measure resistance on plug B of the instrument cluster between pin 2 and pin 18	5 to 10 Step 6	Step 5
5	Replace sensor for oil level indicator		->End
6	Replace instrument cluster		->End
