Leading evidence: 'Replace under my warranty' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace under my warranty' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi Everyone,
Yesterday I went for a pretty spirited drive (that is what you call it when the drive is fast, right ;-)
The oiltemp. was just above normal (a few mm. on the right to 80).
After decelerating for a red light the and the engine was in idle, the oil-pressure went down to one (bar/PSI, cannot recall what the scale is) and the oil-pressure warning suddenly came on for one second and disappeared.
The engine is really running fine, and I wonder how much I should worry about this.
I drive in pretty extremely warm conditions, about 45 degrees celcius outside temperature.
I wonder if this can be the oil-pressure release valve or something that may not function properly, or simply a misreading.
Basically, what should I trust most, the preassure-warning or the gauge?
Anyone had the same issue?

Hi,
It's just a fault on the oil pressure sensor and is relatively common. As long as there is no other symptoms (ie. smoke from exhaust, oil under car etc.), I wouldn't worry about it.
It's also covered under warranty.
I would check both your oil level and the type of oil in your car - the oil type should be detailed in your last service invoice.
Low pressure, if it's real, will cause premature wearing of your crankshaft and camshaft bearings and could lead to catastrophic engine failure. My advise would be to get it checked out. If your car doesn't have a warranty it might be an idea to get one quick - just in case.
Let us know how you get on.

a dodgy oil pressure sender is a known fault. However, I have read that there is a dual circuit design and the gauge is a seperate reading from the warning light. When the gauge is faulty it usually either reads full max or complete zero.
I think you need an oil change.
I had my sensor fail and oil pressure indicator on dash intermitantly fell to zero and then returned to its normal reading a few minutes later. This was replaced under my warranty.
