    Thanks for the added info, I didn't realize you had edited your post until today. This is quite interesting:

    Because you observed this before I wrote about DOT4 LV possibly effecting the ABS system there isn't any way that you were influenced by it.

    I know very little about the differences between E46's and E46 M3's but realoem lists a precharge pump for all years M3:

    Another light bulb just went off in my head. If you do a google image search for BMW CDV you'll notice that the CDV's don't all have the same size hole in them:

    https://www.google.com/search?q=bmw+...&bih=769&dpr=1

    And it is known that despite having the same part number, the CDV's on M3's look different than the ones on non M3's.

    Check out figure 4 here:

    The hole in mine is TINY, a #53 drill bit. I'll bet that the M3 CDV has a larger hole for use with DOT4.

    So... in conclusion... one should or shouldn't remove the CDV?

    I think the ETK has that info wrong. The 2003+ M3s use the same system as the M3 CSL, and the CSL doesn't have a precharge pump listed. Wouldn't be the first time that there's a mistake in there

    On a different note, the Z4M has the same CDV (same part number) as the E46 M3, and those cars specify DOT4 LV

    The only time abs was kicking in early was when I started to overheat pads

    Do you drive it in snow/ice? Viscosity in cold weather will be more than at high temperatures. I suspect that cold viscosity is most important for ABS in snow/ice (especially if you haven't been driving all day)

    MK60e5. Don't know if they added the precharge pump back to those.



    What kinda sucks is that there aren't really any low viscosity fluids with competitive dry/wet boiling points. The various DOT5.1 fluids are close, so that's probably the route I'll go.

    Extremely old thread but somebody might benefit from this info. BMW now only carries LV fluid at their dealerships so you no longer need to pony up extra cash for Pentosin DOT4 LV etc. Here are the part numbers you are looking for (I could not find these part numbers on FCP Euro, ECS tuning etc):

    83132405977 - 1L
    83132405976 - 500ML

    Price was $17.30 for the 1L bottle at Budd's BMW in Oakville, ON (Canada).
