So, I've had the car around 4 weeks now and when i bought it the oil level on the dipstick and the idrive were fine (dipstick was at max) but last week the idrive started to show the level as high whereas on the dipstick it had not moved. Anyway i decided to leave it as after speaking to my usual (ex BMW) indy he said they're known to have the sensors to start playing up.
But as ever me being me i decided to ring the warranty company up as i have 3 months of platinum cover with the RAC and they said they'd cover the replacement of the sensor so I contacted a different BM specialist (as my normal guy is not VAT registered) and explained the issue...Now, here's the twist, he said that apparently, BMW had made the dipsticks too long and that it affected a number of other model (GT) ranges as well and all that is needed is a bit of oil drained...He advised that if the sensor was playing up then there would be an error logged, which makes sense but ISTA does not show any errors.
Anyway, i decided to suck out some oil via the dipstick tube and got the level down to the minimum on the dipstick and guess what the Idrive turned back to green (after driving a couple of miles) with the level showing at the max on the screen.
I've decided to push on with the sensor replacement under warranty but logic tells me to believe what the dipstick is showing...I've googled around and cannot find a single story about dipstick defects affecting BMW's.
Would be interested to hear from people who may have had a similar issue?
