    Yes, I didn't know which one to press. Apparently the regular F148 didn't work, but the F148 (petrol) did.

    I did the oil change today. The actual oil change wasn't bad at all, but taking the underbelly pan off was a pain, and even more of a pain to line it up and put it back on. As others have mentioned, the ducts are what made it even more difficult.
    The hint that I can give anyone doing this for the first time is:

    1- Definitely have a friend help you
    2- Unscrew the ducts first, then drop the belly pan
    3- when re-installing, stick the ducts in, then put the pan close, and screw the ducts in loosely. Then lift the pan into place and tack it up with a few belly pan screws near the duct. Then do the same with the other side. After that, keep adding screws by hand until all the screws (all 90 of them, lol) are in. Finish up by tightening everything.
    4- re-check all the screws after you tighten them
    5- Did I mention, get a friend?

    Just a little extra info: My car took exactly 10.5 Qt. after letting all 3 drains drip for over an hour.


    (By the way, I looked further into the "rumor" that the tool will only do 8 oil service resets before a dealer needs to do a reset through FNA, that reset will clear the 8 spots again. Unfortunately, someone asked the service manager at my local dealer, and confirmed it to be true! I also heard that it cost approx. $500 to have this done. Definitely not cool!)

    I had also posted that video in the oil change thread. It does confirm towards the end of the video that the Launch tool resets the light. My Launch tool also worked on my 458 and even reset the light on my wife's Boxster which I had been trying to do for years.

    I've watched a few of his videos and this guy is a real hack though. I wouldn't recommend following everything he does, like not bothering to go buy the correct socket for the oil filter cap or removing the diffuser (which isn't even necessary) and just letting it drop on the ground. There's another video were he almost destroys a 458 brake caliper by not knowing the correct way to use a bolt extractor.

    I also found that Ricambi sells all the oil change parts as a kit - https://www.ricambiamerica.com/collections/oil-change-kits/458ock-458-italia-oil-change-kit.html

    I did not get pictures but I did DIY the DCT fluid and the gear oil.

    I used Motul DCT fluid and Motul Gear 300 LS 75w 90. I went with the LS for the additive.

    The drain plug for the DCTF fluid is in the middle on the passenger side on the bottom. The plug in front and in back on the bottom on the passenger side is for the gear oil.

    I measured what came out and it was around 6 liters. The factory manual says right at 8 liters. I did let it drain for a while and got a quart or more after the first hour had passed. The moral of the story is let it drain for a few hours.

    filling it was interesting as you need gravity or pressure on your side. I did not want to spend the money on a pressure filler that would sit in the garage for ever after being used once so i went another route. The Motul bottles have a built in spout on them that a piece of 3/8 vinyl tubing will fit over as long at it is somewhat warm. So I went to the hardware store and purchased 6’ of tubing. The transmission plug is a 16mm by 1.5 which a barbed fitting that size is not readily available in the US. I purchased a Teflon or plastic 3/8 male iron pipe by 3/8 barbed fitting to attach the vinyl hose to. I went plastic as to not damage the threads on the transmission since it was the incorrect thread. I used a lot of Teflon tape on the fitting and screwed it in the transmission by hand. The 3/8 is slightly smaller that the 16mm and it fits pretty well with the Teflon tape.

    I connected the vinyl tube to the barbed fitting and to the nozzle on the Motul bottle. I held the Motul bottle up high and the fluid flowed into the transmission as I had gravity working for me. I did poke a small vent hole in the bottom of the bottle While it was upside down.

    after about 4 liters it reached refusal. I cranked the car and put it in reverse and first gear for about 30 seconds. I left a bottle attached to the hose to catch any overflow. After running for 30 seconds or so I **** off and it easily took almost 2 more liters. Which was the amount that came out. I watched the temperatures on the car via the VDA cluster and checked the fluid for the last little bit of the liter. I found if you leave the hose connected to a bottle you can see the fluid flow through the clear vinyl and not make a mess and see when it is full. You can also easily squeeze more into it if needed to adjust the level.

    the gear oil drains through two plugs. The one in the front and the one in the back on the passenger side. It fills through a plug on the rear that is a few inches up from the bottom of the transmission.

    I had about 3.5 liters drain out of this one and again let it drain for a while.

    filling was done by the Motul bottle nozzle. I wadded you the plastic bottle to get the fluid in and it worked pretty well. It held about 2 liters before having to be cranked for the 30 seconds or so and run through reverse and forward. The other 1.5 liters went in pretty easily.

    I did not replace any of the O rings on the drain plug which are more a square section gasket than a circle. They were supple and seemed to seal quite well. I tried to torque the plugs but they did not really like that as they were not smooth when they bottomed out. I used a ratchet and experience to tighten them. I suspect I am a little over what they recommend for torque but not by much.

    I reviewed the fluid that came out for big metal pieces and none were found. Just some small particles of metal floating around in the bottom of the pan.

    I can say that I do notice a little change in the shifts as they seem to be smoother with the Motul.

    I have right at 40k miles. I am not a believer in lifetime fluids.

    I also changed the coolant and will do a write up on that shortly. It was really easy. I should caveat that with the fact I have a quick jack.

    I still have the power steering fluid to change. I am contemplating on how to do that one.

    Coming time I will post / ask many things about the coming maintenance of my '12 458 Italia in March.

    Reason: I will not visit the off F dealer who charge me € 1100 for the next service, it is the first one out of the 7 years free services.

    Only drove 3000 kms and I find it absolutely not rational to renew the 10 ltrs of oil.

    Nowadays imo, you can easily do 40.000 kms withe the modern oils without any problems.

    Also my airfilter is hardly used, I will vacuumclean the box and filter.

    Only thing that worries me at the moment are the sparkplugs, I cannot recall that the F dealer ever exchanged them.

    Can anybody chime in here ?

    And which ones are oem ? and which one (f.i. IGK Iridium) can be used as well ?

    Has anyone replaced the sending unit on their 458? In the shop manual it says to remove manifold. However, with a little struggle, it seems that I would be able to reach down to remove it without all that extra work.
    Here are 2 videos. One is the car idling, and the other is at a steady speed. Notice how the needle seems erratic.
    Can others check their cars and tell me if it's normal or not? If not, I have to look into replacing the sending unit.
