Yellow Oil Light

[rstoughy]

Had the yellow oil light pop up upon shut down of the engine yesterday.

Id just done a run of over 150 miles over some of scotlands best roads through the Grampian Mountains so plenty of elevation changes etc etc.

Has not happened since.

Just the up's and downs of the hills or low on oil???
Car historically doesnt use oil that much so was a little surprised as I had it changed only 1500miles ago.

Just a top up required??

Did you take an instantaneous reading?

[Trawler]

What was your last long term reading? Was there no indication the level was dropping? Was it filled up to max at the last oil change? I would put in 0.2l, drive it for a short distance to see if the problem (yellow light) reoccurs. I need to check the hand book, but I believe you can drive for a short distance before needing to top up so no damage should result. Instantaneous reading will then give you an idea if you are low or high

If in doubt, remove airbox and check dip stick. Takes 5 mins. Whilst your there clean out the intake trumpets. No 5 and 6 will be filthy. :thumbs:

or the oil level sensor itself crapping out as they do on all crappy BMW sensors ....

Spot on :thumbs: :thumbs:

Think your right Shane, i'll pop the airbox tomorrow and check with the stick just to be sure :smokin:

God knows why none of you have not fitted oil catch cans yet??
Get rid of that breather hose polluting your throttle bodies, ICV, air rail, trumpets and inside the airbox!

Filthy is an understatement Shane :bigcry: they were utterly cacked :bigcry:
All nice and clean now though.

Anyone done the above on the CSL?
Looking at the state of the inside of the airbox it would be something worth considering i think.

Did it need topping up Paul,or was it ok on the dip stick.

Not really Brett, was just below the max line, gave it a splash though anyway and after a run its seems to be fine :smokin:

Nice one.

Regarding your trumpets (ooooerrrr) had you ever removed the airbox before? I cleaned mine last year and then this year when I went in to clean it out again, it wasn't too bad. But I suppose, 4K in a year doesn't really warrant that much regular cleaning for myself.

First time I done it though, around 30K miles when I fitted the ITG Filter, they were black as fook. The guys in the shed fitting the lights thought I was a crazy man with the hoover in the airbox sucking out the dust, dirt and sand. God know where that all come from, but you just never know.

Glad you got sorted with your oil though, might be a sensor on its way out. I was quoted £100 to fit one by the dealers but I doubt it'd be that much if you had it done together with an Oil Service? Warranty though? Hmmm

[rstoughy]

No never removed it Baz, only time its been open was while in the garage for its insp II so probably only had a dicht with a cloth.

While i have it apart over the winter i think i'll do the regular M3 dip stick conversion as Tom mentioned.

Here you go this is mine, not only keeps intake clean, but stops blow by gasses mixing with your intake mixture, which decreases the octane rating of the mixture.
