2007 X3 (E83)

[louthster]

Good morning my fellow X3 owners, greetings from an overcast Welwyn, Herts, Uk, I find my old 2007 x3 2.0d Msport is a bit sluggish so I was thinking about getting her remapped but as the car has 162000 miles on her im worried a remap will cause the car to go wrong, ie turbo etc, what are your thoughts, advice etc, also she's hard to start from cold & always needs the accelerator pressing to get her going, from warm its 1st turn of the key, any ideas, finally, I sometimes get a diesely fumes smell in cabin esp sitting in traffic, but the pollen filter looks clean, all ideas & advice greatly appreciated, stay safe out there & TGIF

Hi David....welcome to the Forum

Sounds like the glow plugs need replacing to get it starting properly.

You could try a tuning box (DTUK do a good one)

Thanks young fella & that's exactly what I was thinking cos when she's warm she starts no problem at all :)
