    X5 40d Diesel Tuning boxs - Has anyone bought one that works? Having tried two different types of Tuning Box for my 2012 X5 40d, neither have worked. The ECU shuts down over 3500revs. Has anyone bought one that works or had the same problem?

    The engine on yours is a highly tuned version of the twin turbo 3 litre diesel and quite new to the market, firstly I very much doubt the tuning boxes on market are designed for twin turbo N57 engine (most are for the older M57 engines) and secondly you are already pushing some serious power out a 3 litre block with the standard setup, I am not sure there is much room for more "stable" power to be honest.

    I would have a chat to the forum tuners to see what can be achieved but you already have one of the most powerful dervs on the market.

    Just to add as well... what does an X5 40d cost? Must be pushing £60k...

    At lease give it the respect it deserves by letting a good engine tuner look at it - bound to have a far better effect than a £300 'box of magic' (which in effect I'm sure is just trying to dump more fuel into the engine).

    Plenty of good re-mappers on here - check out the forum vendors section
