Product description
It is quite common for this oil pressure switch to be the cause of a minor oil leak. A correctly functioning switch is, however, primarily important for monitoring the oil pressure. When the oil pressure becomes too low, the switch causes the warning light on the dashboard to illuminate.
Therefore, regularly check the operation of the system. With the ignition switched on and the engine stopped, the oil pressure warning light should be illuminated. Once the engine is running and sufficient oil pressure has built up, the warning light should go out. If it remains illuminated while the engine is running, switch off the engine immediately and check the cause.
Volkswagen specifies a nominal switching pressure of 0.30 bar for this oil pressure switch. According to the Volkswagen specification, the warning light may switch off at a rising oil pressure between 0.15 and 0.45 bar.
The manufacturer of this B-quality version specifies a switching pressure of 0.30 bar. To see how this works in practice, we tested a total of six switches. They operated at 0.55, 0.15, 0.20, 0.27, 0.20 and 0.25 bar.
The measured values show that the switching pressure can vary somewhat more between individual switches. Importantly, in our test none of the six switches operated below Volkswagen’s specified lower limit of 0.15 bar. Five of the six tested switches were within Volkswagen’s specified tolerance; one switch operated at 0.55 bar.
Under the Alternatives tab you will also find the A-quality version. The manufacturer specifies a range of 0.15 to 0.45 bar for this version. The three switches we tested operated at 0.35, 0.30 and 0.30 bar, resulting in less variation between the individual switches.
Note: The original Volkswagen oil pressure switch has a tapered thread which tightens as it is screwed in and therefore provides the seal. On reproduction switches, the range of this taper may differ. Check this during installation. If the switch starts to tighten noticeably about halfway in, the tapered thread can provide the seal. If the switch can be screwed in almost completely without the thread tightening, use a small amount of suitable, oil-resistant thread sealant.
Do not use thread-locking compound.
