Any DCT's replaced?
Just curious how many miles a DCT should last for. Assuming it hasnt been launched a bunch of times My SA says 75k miles.
Wondering for those with the clutch replaced, how many miles. I was going for a E60 M5 but scared to death with all the SMG issues.

There is no way BMW built a transmission with a 75k mile life. Some may go out then or sooner, but I would be surprised if non-abused ones last much longer.

Doesn't seem like anyone has had them replaced due to wear over time. Mostly early in cars life or SC'd which says nothing about longevity to me. Still no real answers about DCT life, but think in this instance "no news is good news"

I do know the performance school at the plant does not replace DCTs but they replace the clutches and flywheels (wear items), but I do not know how often. Those cars are run hard and put away wet. John |

The DCT is basically an "off the shelf" transmission built by Getrag used under licence by BMW. The design spec of the DCT permits it to be used in cars with more power and more torque. The multi disk wet clutch is closer in design to the clutch packs used in differentials than those used in MTs with the attendant very long life expectancy. The way that gears are preselected means that you won't get the damage to gears and synco rings that can occur in an MT due to misuse. Anecdotal failure rates for DCT seem to be extremely low however a failure out of warranty could be pricey - although the fact that a DCT is defined as a sealed for life unit would put BMW in a difficult position if you pressed them in court for some sort of good will payment.
