Apologies if this has been covered before.

On rare occasions, the 'low oil level sensor' came on whilst driving my MK2 1.9 PD Superb. After checking the dipstick (and topping up with oil), I came to realize that on that car, the warning did correlate to the lower markings on the dipstick, so not in the 'Danger Zone' at all, a very useful safety-net for the high-mileage driver!

Does anyone know if the current, MK4 2.0 diesel, has the same warning system? If so, is it as accurate?

Asking for a friend.

Cheers!

I would suggest not relying on the sensor - IMO, nothing is a substitute for regular checks of the stick.

The mk4 Superb does not have a physical dipstick https://www.briskoda.net/forums/topic/532601-virtual-dipstick/

...but, apparently, one can be retrofitted.

It can, but if you can check it from the comfort of the drivers seat........

My mk4 Superb L&K 2.0 TDi has a dipstick, it was already installed on delivery (Feb 2025)…

...but completely pointless if its accuracy is in any way suspect.

I understand your reasoning, but how often do you dip your fuel tank?

I'm guessing like most people do you rely on a fuel gauge which is likely to be reasonably accurate.

As far as I am aware no one on this forum has had a problem so far regarding any engine or related failures due to using the oil gauge and not a dipstick, and if they did I'm sure we would have heard by now.

What makes you think the gauge could be suspect? - time to embrace modern technology!

Running out of fuel will be an inconvenience - although I do not rely solely on fuel gauge, but use trip odo as well - running out of oil can often be catastrophic.

There are a number of posts on the forum where either the low-oil has not lit when the level was low - and others where the indicator has lit (or remained lit after topping oil up) when the oil was above the minimum level.

All this would strongly suggest that it may be unwise to rely solely on 'modern technology'!

I have not seen those forum posts that you are talking about but at least the one which reads low-oil warning indicator was lit even when oil was above minimum level sounds like the system could be working okay and exactly as designed. There are 8 digital lines between minimum and maximum oil level and to my understanding the low-oil warning comes when the oil level is 2 lit digital lines above minimum and this is by design to encourage topping up the oil before anything gets broken. The logic is the same as low-fuel warning comes before actually running out of fuel.

Those others sound more like the digital oil gauge is broken rather than an accuracy problem. I guess the digital oil gauge can get broken like any other system in the car.

My digital oil gauge seems to work logically without any major faults and I have no reason to suspect the accuracy.

I don't know how accurate some self mounted dipstick system is. It could also be completely out of whack and show wrong when the digital gauge is correct.

Thanks for all the repliies on this, gents!

Much appreciated, and all duly noted!

A bit late to the game…….

However my 75 plate Superb SE L 2.0tdi 150, has a physical dipstick (I’m very happy to say).
