  1. Can't measure oil - have updated oil pump (WAA03)

    Yep as I said I've done all this and it's in line with a perfectly good oil pump. My cars under warranty but I'm tuned so it's not gonna work out for me I'll have to get any work done by an indie garage.
  2. Can't measure oil - have updated oil pump (WAA03)

    First time watching that oil pump video. Excellent DIY step by step instructions. That little 5’4” gal put 90% of us to shame with her capabilities. I was even a little skeptical about doing the work myself. ? -RJM
  3. Can't measure oil - have updated oil pump (WAA03)

    You can do this with Bimmerlink. You can view and log oil pressure. You can also view and log oil level.
  4. Can't measure oil - have updated oil pump (WAA03)

    Yes, @Faye ordered the 15100-WAA03 pump from a Toyota dealer and received the 11419895359 part:
  5. Can't measure oil - have updated oil pump (WAA03)

    Also does anyone know for sure if the BMW Z4 Oil Pump 11419895359 is the exact same? It's less than half the price than from Toyota here in UK
  6. Can't measure oil - have updated oil pump (WAA03)

    ...the updated pump. Also - my oil pressure doesn't really go up while doing the measuring test which others said is a tell tale sign of an oil pump starting to fail. It stays around the 3-3.3 bar mark Thirdly - there are no stories of failed pumps over here in UE/UK that I can find. All the...
  7. Can't measure oil - have updated oil pump (WAA03)

    You have a 2020 though, you won't have the updated oil pump is what I'm guessing. It probably shows that you have the updated pump because they've moved towards that moving forward?
  8. Can't measure oil - have updated oil pump (WAA03)

    ...30 mins, flat surface, letting it cool down etc but keeps stopping at 18-20%. I know everyone here is going to tell me I need an updated Oil pump but here's the kicker - My car already has the metal WAA03 pump which was confirmed by Toyota today using my VIN number. It seems that others in...
  9. How do you get the Oil Level Check to work

    it's linked to pressure being too high, not necessarily oil being too hot. with the new oil pump, it will do a better job of controlling oil pressure so you won't experience the high pressure scenario that puts the measurement system outside of it's tolerance. that's why it fails at 16%. oil...
  10. Razorlab - 2020 LE build thread

    Cool, if your pump is still happily going after 22k hard fought track miles I feel a bit better on mine carrying on after 9k normal (ish) road miles! ? With the bits you are doing at the moment, what do you think the performance increase will be over last season? You must be seriously hitting...
  11. Razorlab - 2020 LE build thread

    Yes, I am. However I am keeping an eye on it because I am sure I will need to replace it at some point. The car has relatively low miles, about 22k miles, although a lot of them are track miles. The car has over 65 track days on it at this point. I have also used the forbidden fruit 5w40 oil...
  12. Razorlab - 2020 LE build thread

    I have a question! Are you still running the original oil pump? I saw a couple threads pop up about this where our early 2020 cars supposedly have dodgy pumps with plastic parts in them which seems a pretty strange thing to do!
  13. How do you get the Oil Level Check to work

    99.9% chance it’s a failing oil pump. Mine did the same thing.
  14. How do you get the Oil Level Check to work

    Ya I tried letting it cool, 5 minutes, 15 minutes, 30 minutes, didn't help. The start measurement was still available after 30 minutes and it still failed. I tried every suggestion in the manual, in forums, even tried AI. No good. Thanks for the info though.
  15. How do you get the Oil Level Check to work

    I was having same problem, 2020. Did some research and turns out the oil can be too hot to measure as well as too cold. I had to turn my car off let it cool for a bit, then turn it back on and it worked just fine. I thought I needed a new pump or sensor but nope, all fine.
  16. How do you get the Oil Level Check to work

    The new pumps part number supersedes the old one so dealers can only order the updated one. I didn’t mention anything about online stuff even though I knew the oil pump would fix it I just let them do there thing.
  17. How do you get the Oil Level Check to work

    they dont care whats online. just let them know your issue and let them go from there lol
  18. How do you get the Oil Level Check to work

    Tell the dealer its a well known issue with the oil pump and it's failure mode anyway but they won't believe you. They'll want to replace the oil qty sender unit first and when that doesn't fix the issue then they'll go with the pump. Just the way it seems to work with dealers, ignore the...
  19. How do you get the Oil Level Check to work

    ...just tell them that the oil level check fails and then they'll just figure it out or should I mention I read online it could need the upgraded oil pump or new sensors? If that's it and they replace the oil pump, would they replace it with the same plastic one or is only the metal one...
  20. How do you get the Oil Level Check to work

    The earlier models used an oil pump with plastic internals. Updated one has metal internals. Early signs of failure are being unable to measure engine oil and eventually oil pressure issues and then worst case total oil pump failure. There’s a lot of similar posts on here with the same issues...
