Image: BMW 1 Series Window Regulator Lifter for £26.59   The window goes down fine. Coming back up, it moves a few centimetres, stops, and you hear a clicking or grinding sound. Or it goes up but sits at a slight angle. Or it works perfectly on a warm day and refuses to move at all when it is cold. These are the signs of a failing BMW window regulator , the mechanism inside the door that actually moves the glass. On most newer BMW models, the window regulator is a cable-driven system. A small electric motor turns a drum, winding and unwinding cables that are attached to a carrier that the glass clips onto. When any part of this system wears, stretches, or breaks, the symptoms below follow. The Main Symptoms The window moves slowly or unevenly. A regulator that is beginning to wear will often show this first. The glass drops or rises sluggishly, taking noticeably longer than it used to, or moving in a jerky, uneven way rather than a smooth continuous motion. This is the early warn...

  Image: BMW 5 Series (F10) Complete Sunroof SERIES COMPLETE SUNROOF for £141.85 at MT Auto Parts     Water inside the cabin of a BMW is one of those problems that gets worse the longer you ignore it. A damp patch on the headliner becomes a wet footwell. A wet footwell becomes a corroded module. A corroded module becomes an expensive repair that traces back to a blocked drainage tube that could have been cleared for almost nothing. BMW panoramic sunroofs are one of the more common sources of water ingress on UK cars. Not because they are badly made, but because they rely on a drainage system that most owners do not know exists, and therefore never maintain. How the Drainage System Works — and Why It Matters The BMW panoramic sunroof is not a sealed unit. It is designed to let a small amount of water past the glass seals during heavy rain, then channel that water away through four drain tubes, one at each corner of the sunroof frame, that run down through the A and C...
