hi,
im about to do the serpentine belt change, thinking about purchasing this brand. Its the same that comes with the ecs tuning serpentine belt kit. Wanted to see if anyone has had problems with it. Im between buying the Genuine Bmw belt or this contitech belt. Its almost half of the original bmw price.

BMW Alternator Drive Belt - Contitech 7PK1855

Serpentine Belt Tensioner - pulley included - Genuine BMW
Part # : 11 28 7 563 927

Serpentine Belt Idler Pulley - Upper - Genuine BMW

Serpentine Belt Idler Pulley - Lower - Genuine BMW

Go on ecs and buy the aftermarket belt kit. INA makes the idlers and tensioners and conti makes the factory BMW belts. The idlers and tensioner will be 100% identical to what comes off the car. The belt won't say BMW on it and but is a quality belt. You are throwing money away buying BMW idlers and a tensioner.
