I recently broke my driver's interior door handle, the chassis of the handle is bolted to the door pannel than the cover which holds the window controls gets pushed down onto the chassis. What i found is that the normal passat b5 chassis doesn't fit on a superb's door. Did anyone else have this problem before and where do you even get a handle that would fit.

I'm having the same issue. both the bigger bits are broken, in my case probably because I appear to be missing one of the 3 screws holding it on to the door.

 

If your car is LHD, you may find suitable items on ebay, if it's a UK RHD car, you're probably best off to the local skoda dealer. It's where I'll be trying my hand soon.
