Worst service in the universe

My BMW gearbox oil leaked put because a previous supplier did not fit the quick coupling back properly on the oil cooler i fixed it and also filled the gearbox oil to the correct level<br> The only problem is that the car needs to be reset as it is in limp mode went to zambesi bmw in one gear and spoke to the workshop the guy did not even introduce himself just plainly said we have to re-program the computer and you have to book it in and it will cost you R52000 .What nonsense got a guy for R259 to reset it now it is working fine done 900 km since<br> If this is the attitude of Zambezi BMW this will be the last BMW i will ever drive will get rid of It asap
