Oil level indicator

[kindlethespirit]

Recently I had the IMS, RMS, AOS, flywheel, clutch, rear CV axles and oil changed by my local Pcar indy shop.

The oil indicator level on the dash has always agreed with the dipstick in the past. Since I've had the car back, 4 days, the two no longer agree.

Several times I've turned the key and waited for the oil level on the dash to display and it's been showing 1 bar above the lowest level possible. I immediately check the dipstick and it shows that the oil is right at the top notch on the dipstick, so it's fine. Once I drive it and the oil is hot, when I shut the car off and wait for the indicator to retest, it will show 2 bars below the highest level.

What could have changed with the above service that now my dash indicator is so inaccurate? It makes me nervous to not be able to rely any longer on that as a general idea of the amount of oil that is in the car.

Yes, the car is on the level when measuring the oil.
