Good morning,

Today we present a case reported by the workshop Pozzati Alberto, who later informed us that the problem has been resolved:

2016 Suzuki Vitara 4×4 1.6 DDIS 88 Kw (120 hp).

On the road travelling constantly at 100-120 km/h, the engine fault light came on, the error was detected in the diagnosis: P1541 solenoid valve variable flow oil pump. When the problem occurred, the low oil pressure light did not come on.

The colleague had already replaced the VDOP oil flow control solenoid valve on the pump, the engine oil and the filter, but the problem persisted; the wiring did not show any anomalies.

Given what had already been carried out and also the type of engine, which is the well-known 1.6 Multijet, the diagnosis was diverted to the oil pressure sensors, in particular to a possible high-pressure sensor starvation (grey in colour, the low-pressure sensor is black) given also the conditions in which the defect was manifesting itself.

After further checks of the sensor wiring, the colleague replaced the sensor, which was the solution to the problem.

On behalf of the Help Desk team, we thank our colleague for his report and wish you good work
