    So for the completeness of this thread: it was indeed the input shaft bearing, which I have replaced and now the gearbox is silent, the whine noise has disappeared.

    For those that may need to...

    In my case, I received my own copy that I have downloaded one year or so ago, and handed it to the friend that used it (without Cobb) and still had it when I asked it, so it is actually registered on...

    Wrong. The ATR does not have anything to do with flashing maps (or, if it has, I don't use it that way), I use AP Manager to transfer the maps and flash them.

    I got it from a friend, thanks. If anyone needs the N54 IJE0S version of Cobb ATR, please PM me. I'm not looking too often on this forum but I will for the following days/weeks.
  5. Help needed, I need the Cobb AccessTuner Race software for N54 IJE0S

    Hello everyone,

    After around 2 years in which I ran my own custom-made Cobb maps on my RB-Turbo N54 335i, basically forgetting that I have a tune, the need arised to download the AccessTuner Race...

    Thanks for the input, it gives me some hope that I can fix this sometime for a reasonable cost. But I will first wait a bit, maybe it will just quiet down on its own (though it really doesn't sound...

    Although it is highly improbable for the pilot bearing to play a role (since it simply does not move when the clutch pedal is not pressed) all the dual-mass flywheels that I have installed in my car...

    They say they don't have any idea. I was present the whole time when the work was done, nothing unusual happened that I know of, but they used a pit instead of a lift so I couldn't see everything...

    Hello everyone,

    I have a slight issue with my with the my 6MT 335i (N54) after an indy shop installed a new clutch, flywheel and throw-out bearing. The flywheel is a LuK 415037710 unit (identical...

    It's the diff that failed. Will be sent to Drexler for repair. It lasted 4 years and 40.000 miles with not more than 20 drag launches, the rest was moderate to aggressive driving. Hopefully next time...

    Hello,

    This happened to me a very short time ago...while decelerating gently from about 65mph (brake pedal gently pressed) I heard a loud thump from the rear of the car, and now I hear repetitive...

  13. 2-year Follow-Up

    Here is a 2-year follow-up on my cluch review:


    The clutch behaved flawlessly over this time. It never ever slipped. But I did not launch it with drag radials more than 10-15 times. However, I...

  15. Cobb N54 - AFR too lean in spool mode accelerati​on (short log and map attached)

    Hello all,

    I have this strange problem with my Cobb N54 which puzzles me. I have full bolt-ons and RB turbos and using 91 octane fuel with no methanol and no e85.

    I tuned the car myself for a...

    My problem has not appeared since that day. Everything goes smoothly, I do hear the thump when selecting reverse but I think it's normal. I will postpone any checks until the spring.

    I think I will bleed the clutch first, to see what happens.



    You described the noise perfectly, but to me it sounds like the driveshaft moving and trying to spin the diff, then stops because...

    Yes, aftermarket LSD (Drexler) and M3 subframe bushings.

    6MT 335i N54 here.

    Today something new happened with my car: when I tried to put it in reverse when parking (drove normally all day, did not push the car), it was difficult to select the...

    O2 sensor extension cables ?

    Hi,

    N54 owner here.


    My spring project is to be nice to environment and mount some HJS 200-cell cats. I am looking to find some extension cables (or at the very least the sockets) for the...

    It just doesn't matter whether it is V8 or a six-cylinder if they have the same capacity.

    And when they say "it's the most...in it's class" this is just marketing, because in a "class" they can...

    Not sure where you got this from, did the Engine of The Year award fool you ? :)

    Overall, a great car, with so many improvements over the standard car and engine. Its power to weight ratio is equal or better than the current M5, so it should be very fast. I think it should be...

    Of course it is, if you want your car to consume less fuel. There is a huge difference in fuel consumption between port injection and direct injection. Direct injection is the reason why a 335i can...
