Hi all

i have a BMW X6 35d and I’ve recently started having trouble with it.

Sometimes when i accelerate the car barely wants to move even if my foot is planted to the floor. I can even drop down gear manually and it still won’t go.

And then sometimes all of a sudden it will then pickup and go. There seems to be no pattern as to when it does and doesn’t do it.

the only was I can describe it is .... trying to run and someone’s squeezing your lungs.

no engine management light etc has come on.

Can anyone suggest anything? I did plug in a wireless device to check for error codes but the error code of P1523 Powertrain wasn’t recognised by the software or their companies website.

thanks in advance!
