Hi Warren.....welcome to the Forum I have previously owned a Tuning Box (on a Honda CRV 2.2 cdti) and unfortunately sold it when I sold the car. It takes about 10 -15 minutes to fit yourself. However, in the time that I have it fitted, it vastly improved the driveability of the car, made it more flexible on the transmission (didn't need to change up constantly to maintain road speed), the economy improved by at least 15% and quite frankly cried when I took it off....what a difference it made! I fitted it with the intention of improving the economy and this is exactly what it did....I didn't however, buy it with a huge performance increase in mind. I would say, go for it, you won't regret it !

Hi Craig....welcome to the Forum ....welcome also to the wonderful world of BMW Good to have you onboard

oh dear! Just as important as winding back a caliper piston is to ensure it is done correctly...e.g. hose clamped so no pressure is going up in the reverse direction into the ABS modulator or Master Cylinder (only takes a few seconds to fit) and then crack the bleed nipple off and twist or push the piston back in....zero pressure required as the bleed nipple is open and also expels the old fluid. Takes about 20 seconds longer and ensures zero damage to the braking system.

Hi Andy....welcome to the Forum If it has an electronic handbrake then the motors will need to be put into service mode to replace the pads and the calipers would still need winding back as well Let us know how you get on with it

Thanks for the update Andy That is unbelievable, I cannot believe it is not a Safety Recall already, I would be more tempted to contact VOSA https://www.gov.uk/government/organisations/vehicle-and-operator-services-agency and report the information to them. If they believe it is a serious concern then they can escalate it to BMW. Huge error on BMWs part by using the wrong bolts that stretch and shear....probably overtorqued aswell
