Hoping someone might have had the same experience......

Just started my D600 as it has been stood for 2 weeks. Started great, the oil light went out for a second or 2 then came back on. Left it a couple of seconds but still on so turned the engine off.

Any ideas? The oil level is good so I'm guessing (and hoping!) it's just a faulty pressure sensor.

The last time I had it running was two weeks ago after giving it a good clean and there were no problems then.

It's been quite cold round here lately by the way, probably 0°C at the moment, don't know if this has anything to do with it.

Thank you

Cold temps near freezing could definately be a problem depending on the oil weight that you have in there. Before looking to more serious causes, try it again when it is slightly warmer and the oil has a more favorable viscocity.

On a post 1992 British bike the sensor & associated wiring is likely to be less reliable than the oil pump & oilways. So check the sensor & wiring first.

The oil pressure light shows high or low depending on the resistance of the sensor. If highest resistance is when the oil pressure is low then a poor connection could give a false low pressure sign, particulalry if the bike has been standing a while.

To check this take off the connector to the oil pressure switch [bottom of right crankcase end], clean it (with a brass brush or abrasive paper) pinch the female connector with pliers (to make it tighter) and coat it in vaseline (to slow electrolytic corrosion).. Stick it back on and you may get more normal oil pressure readings. Hope this works.

If not ..............the sensor

Is it possible that since the bike was just idling the oil pressure had not built up therefore causing the low pressure light to come on?

Is it the oil light or engine light?

I had this happen to me on my 02 S4, and this method fixed it like a champ... over a year later and no light. The only thing I did different was use dielectric silicone compoud, similar to vasaline, but specificlly for electrical fitting. Good Luck!

I'v just tried cleaning the connection at the pressure sensor and unfortunately no luck.

There's a single wire going to the sensor so looks like the sensor grounds the connection (or removes the ground depending on pressure). With the wire disconnected there is no oil light on the clocks (with ignition on but engine not running), when I reconnect the wire the light comes back on. Guess the sensor should remove the ground when pressure is good.

Guess my next option is to replace the sensor and see what happens. Anyone know a good place to buy spares?

By the way, I'm having to run the engine for 5 seconds or so to check the light - if I do have an oil pressure problem I hope this isn't long enough to do any damage!?

Will

I don't think so. I wouldn't run it much more than that, and I sure wouldn't wind it out at all.

I'd keep running it to an absolute minumum. If you're feel that you're mechanically savvy enough to fix this yourself then fine, but I would personnally get it to a dealer asap. I won't bore you with the full version of a long and potentially boring story, but suffice to say that I had an experience with the oil pressure light on my first D600 that culminated with the big end of the engine going bang on the pit straight at Cadwell Park racetrack. Fortunately the issue was handled under warranty for me.

Be very careful what chances you take.
