    Hi Everyone,

    I'm looking into getting a 335d remapped, most likely through the Forum Vendor (initial contact made).

    I've been reading this site for a while now, and have searched google etc. for all kinds of related posts.

    Please could the good people on here respond with any problems they've had since remaps, or heard about. THings I need to look out for, or problems I'm likely to experience.

    I had my previous Honda Accord remapped, and eventually the clutch started to slip due to the extra power. But this is a known problem on the Accord (and more common on the Civic) diesels so I was prepared for it to happen.

    I'm just looking for more information to prepare myself for any of the pitfalls.


    P.S. I know all the warranty chat -- and that a remap is likely to eliminate it (if found). I'm more interested to hear of any horror stories regarding any parts failing etc.

    Thank you all in advance.
    Gareth

    Don't go full whack as the 335d is very near the torque maximum for the gearbox, if you overdo it you'll be looking at a new box. Treat it with respect, don't try feeding all the torque in at once. I always get mine rolling before I give it some. If your using a Forum Vendor they will better know the pitfalls and won't upgrade with too much power to damage parts.
    Think of it as your body when exercising, let it warm up before giving it the beans and more important let it warm down. Treated well and with regular oil changes there is no reason why it should let you down. Despite what some may say.

    Hi petrolmarty,
    thanks for the quick response. And advice.

    Just wondered what do you mean by "let it warm down"?

    True for the early ZF boxes. They were uprated in 2008 I believe. What year are you looking at ? When you know, search realoem.com and that will tell you the ZF model number and you can cross ref that against the ZF website to ascertain if it's the later uprated box

    Just let it cool down gently before you switch it off. In most cases the last part of a journey is at 20mph or so and that will do it. Just don't come off a Motorway at 80mph into the services and switch it straight off, let it tick over for a few moments to cool the Turbo down and de-stress everything.

    I know you don't want to hear about warranty talk but you said about warranty being invalid IF FOUND! Well the situation is, BMW computers can now tell if your car does not have the software that it is supposed to have i.e a modified map! So as much as you want a remap, just bear what I have said in mind.

    Thanks APtuning, sound advice.
    I think that might be the deciding factor whether I remap or not.

    Or get a solution that allows you easily to switch mapping from tuned to stock.
