    You just pull it out. It's a good fit but they just pull out. I added a dipstick to my car as I don't trust these oil level sensors, much prefer to to do it the old fashioned way. Makes life a lot easier too when changing the oil and filling it back up.
    It will be getting a proper oil change in the summer through the sump plug and not as most have probably been done at the dealers through the dipstick.

    I have a 2010 A4 and I purchased the correct dipstick for the 2.0TDI but it was actually too long. I looked around the internet and this seemed to be a common topic covered. Quoted From "http://www.myaudiq5.com/index.php/topic/1536-adding-a-manual-oil-dipstick/"

    "Earlier models of the 2.0 TDi engine had a longer dipstick tube to bring the dipstick within easy reach. The dipstick is designed to work with this tube. Later engines have no hole in the plastic engine cover for the dipstick to poke through.... and consequently have a shorter dipstick tube. Hence the dipstick is approx 75mm too long when used with the shorter tube. It looks like Audi haven't produced a dipstick for use with the shorter tube.

    So I ended up purchasing generic service workshop dipstick that can be adjusted for any engine. Like Karl I don't trust the MMI completely!lol

    thanks, on closer inspection, the dipstick cap appears to have a couple of plastic lugs which clip/hold it in place onto the dipstick tube
    will these lugs not break off if i just pull the cap out?

    No! The similar dipstick also can have lugs to keep it in place.

    thanks guys. i am very pleased with the support from this forum.

    so i will try to pull off the dipstick cap.

    presumably one can suck the oil out through the dipstick tube with vacuum pump like i have done with bmw cars?

    and the oil dipstick cap is reuseable?

    what size socket is needed to remove the oil filter cap?

    Oh yes, for the dipstick cap being reusable, though if you are doing an oil change, maybe buy a proper dipstick to replace that cap as that is the only way to check you have refilled the sump correctly, I think even the VAG dealers use an adjustable "service dipstick tool" to check level and calibration of oil level monitoring system - if you want, Laser Tools sell a service tool like that used in garages.

    I can't say what the size of the filter case socket is though - sorry.

    Yes, but you wont get it all out.

    Better off spending 10 minutes more and taking the plug out the bottom of the sump.

    I have had mine for years! I bet Halfords sell them.
    Ideally 6 sided, but 12 sided will be OK as its not a lot of torque.

    had a look today on the car-oil dipstick cap came off -you just have to pull it up-i used a vacuum suction tool tube and it goes right to the bottom of the sump so will use the oil suction pump to remove the old oil.i have used this technique successfully on my vw bora tdi and bmw cars over the years with no problems.
    also used 32 mm 12 sided 1/2 inch drive halfords professional socket which fits on the oil filter bolt-it is bit tight for space but managed to loosen the oil filter cap using a flexible 1/2 inch drive with universal jt on it-so i now confident :thumbsup:i can do the oil change myself without having to go under the car.

    You are correct in buying one of these low strength filter sockets, also maybe stick with 3/8" drive as the correct tightening toque will be a bit below the range of a "useful" 1/2" drive torque wrench.

    had a look at the laser website-looks like it would be suitable for 2.0tdi cr(=common rail) engine.
    it would be interesting to know how much audi charge for their dipstick? as the laser on looks competitively priced.

    bought the laser brand oil dipstick tool of ebay for £13.75.
    one audi dealer said it was not availabe and while another one wnated £27 .
    should do the trick to do manual old fashion way of checking oil level.
    the instructions on using it is on the laser tools website

    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.

    dieseldoos original post
    "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)."

    i tried out the laser tool.
    it works,and like you say it scrapes a little while inserting but otherwise good to have.
    does any know how to calibrate the tool to the car's electronic oil measuring system?
    the reason i ask is the dipstick tool reads minimum but the mmi shows 3/4 level of oil
    guess will have to try with car sitting on level ground to see if dipstick tool level matches electronic measurement

    Because you cant suck it totally empty, same as with a glass of coke and a straw. You need to tilt the glass and move the straw until you see it's at the very bottom of the glass. When you drain the oil through the sump plug it all comes out cos the drain is at the lowest point.

    I just put a cable tie close to the top of the dipstick to make it the correct length. I dont leave it in the car.

    i agree but with oil suction thru dipstick you will mange to remove 99% or more of the oil which is good enough for me as i do yearly oil changes without the need to go under the car .Never had an issue with suction tool on my other cars using this method oveR the years.

    It would be interesting to suck the sump out, then take out the plug and see how much more comes out.

    I know what you mean about 99%. There will be oil sitting in galleries etc so it's not bone dry either way.

    I rebuild single cylinder 4 stroke race engines as a hobby, they take 1 litre of oil and regardless of how well you drain them while still in the frame, including tilting the bike around until no more dribbles out, I still get about 30 ml on the bench when I pull them apart.

    i decided to do an oil service today
    i removed the oil filter housing using a 32 mm socket-that was staightforward-was surprised however to see that genuine audi filter was one made by purflux and had an audi part number stamped on it.
    however i was shocked and somewhat disappointed that when i put the oil suction tube to suck the oil out through the dipstick tube-only 2.25 litres or thereabouts came out:uhm::sos:
    now the hand book says the oil capacity including filter change is aprroximately 5 litres.
    the oil level on the mmi was showing a level midway between min and max before i sucked the oil out.
    so i decided to put the old oil filter back in and topped it up with 2.5litres of new 5w30 longlife quantum oil as i believe not all the oil came out with the oil extractor tool-should have had at least 4.5litres come out.
    i will get my mechanic to do an oil change in the traditional way via the oil sump drain plug method.
    so my expereince is that not all the oil comes out with the oil extraction tool and at least 2litres remains behind-i had taken all the precautions-car parked on level ground and waited an hour after car was driven before extracting and oil suction tube was touching bottom of oil pan but i feel it may not at be at the lowest point in the sump and hence about 2 litres of old oil remains behind.
    zafi you were right.
    so my experience is that it is not possible to do an oil service using an oil extractor via dipstick tube method on my car:no:

    I have a 4 post lift at work, but have been known to change the oil at home in the street by parking with the nearside wheels on the kerb and the offside wheels on a 4" stack of timber under each wheel. Thats all the clearance you need to get under to remove the undertray and drain plug.
