I purchased the laser tool also and it works well, but I hated the metal sound when putting it into the dipstick tube it sounded and felt like it was going to break.
I had already purchased 03L 115 611E going by some other websites, but now that the tube is now fully under the cover, the dipstick is to long. So I seen a very useful post from dieseldoos about cutting 03L 115 611E to allow it to fit, and tbh I prefer to use this as my method of checking the oil and its near bang on with the MMI which is great.

"What I did, was had a mate cross reference the level, then trim the bottom of the dipstick, cutting the plastic measuring part of, so you are left with the upper and lower grey plastic on the dipstick.
Its not perfect but it works, and using the upper and lower plastic parts on the dipstick as minimum and maximum I can get an approx reading, (which also matches with his universal adjuster dipstick and the MMI reading)."
