Electronic dipstick giving spurious readings ?

[DazBlackCSL]

Back on the tyre bit !!!

Im moving from the std 265 / 235 set up to 275/245 as recommended by thorney , as he has done extensive testing on both, and reckons the 275/245 handles far better on road and track because of the wider track, also going for some proper race wheels , to keep as a second set , that way I can keep the cups on a set.
Rays RE30's which are lighter than the standard CSL's and have a wider track also, so no need for spacers etc.

Will post up some pics Wed night as im getting then put on during the day..

I have Conti's on my CSL - they were already on and almost brand new when i bought it - but have to say so far they feel perfectly fine on the road - i guess the track day at Brands will give me a better impression.
I did a check on the oil this morning before, during and after a decent length run - exactly how it is described in the CSL manual. The "long term" check read +0.8 which im assuming is perfectly fine. However, when i stopped, turned engine off, waited a good 3 minutes or so, turned ignition to position 1 and held sport button in - it read +1.1 - i know it says that this doesnt give the most accurate readingbut does this seem right??

Had a chat witha BMW technician this morning about checking the oil level with the dipstick. He commented that the airbox screws can become seized and thus be a real PITA to remove.
They used to remove the undertray and check the dipstick from underneath rather than do battle with the screws in the CF airbox . . . .

It sounds like you overfilled your engine by about 2 litres.

0.9l is a normal level. Unless your engine is seriously ill, you would have to drive at least 1000 miles around a track in order to burn off that much oil.

If I was you, I would take your car into a dealer and to get them to check the level manually. This will involve removing the airbox.

I agree - sounds horribly overfilled - and I'm not sure even 1000 miles around a track would burn that much off :119:

I predict a massive oil eruption sometime soon :bigcry: :thumbs:

Xporker,

Have you had the oil level checked?

[glendog74]

I had a weird occurence of the electronic dipstick not registering any reading at all when i left Germany yesterday... It was a full 45 minutes before a reading appeared, having initially displayed '-.-'!

Having just had an Insp II, i was reasonably confident that oil was in fact still in there! :whistle:

No, but have just embarked on a tour of Wales. No rattling noises (apart from a rear damper mount) and no pools of oil underneath.



No comments about nervous looking sheep either please ! (and if they DO look nervous it was the induction noise from the car that caused them to look so . . . )

Great Shot!

mine was the same it takes a while to register, as long as it is a + plus reading it is fine 1.1 is the maximum .5 is halfway as with a normal dpistick the level should be between the min and max there is no need to have it on the maximum

you want to get some oil out as to much is not a good thing you have 2 to 3 litres to much in there

I think that you might have a few big bills coming your way. The head gasket will probably be the first thing to go (due to the very, very high oil level and pressures).

That's not "weird" Glen, it's totally normal behaviour.

All the -- means is that it's been unable to take a longterm reading and the reasons for that are 1) you've been spanking it for a while (eg, trackday) or 2) you only do short journeys.

I generally do about 8 miles a day (to work and back) - car never gets fully warm. As a result my reading is nearly always --

As you say a longer 'normal drive' journey is required to acheive a successful longterm reading :thumbs:

Ahh, that'll be reason 1 then... Spanking is fun though! :snakeman:

We all know that - its good fun thrashing the car too :thumbs:

If indeed it is high, the level should have no impact on cylinder pressures whatsoever, it may however cause somewhat elevated crankcase pressure.

If that were the case I'd expect to see pools of oil all over the floor where the front and rear crankshaft seals had failed or the sump gaskets had given up the unequal task of trying to contain the pressure.

I will do a proper test when I get the opportunity (I did try and do one on the outward leg to Wales but I forgot both the instructions kindly given on here and the CSL supplement to the cars manual) I know I'm a :wanker:

I make no bones about it, the car was used very hard whilst over in France, I'd be very surprised if it has more than one litre of oil over and above the specified amount in it's sump right now. hence my somewhat blase approach !

The car also has the official dealer issued BMW warranty too, from my perspective if there's oil in there when it goes bang it''ll be tricky to prove there was too much in there !

Perhaps I should add I was a muckanic in my dim (apt) and distant past. hence the old phrase about a coblers children being worst shod is proving true !

Promise I'll check it next time out ! :thumbs:
