The BMW windshield moulding is a very easily replaced part that will return your vehicle to looking factory fresh again.

A rotting BMW windshield moulding sticks out like a sore thumb on our bimmers. For some strange reason, our eyes are drawn to a rotten windshield moulding like a fly to a rib roast. Forget about the dings and scratches all over our cars…the deteriorated windshield moulding causes us more gastric reflux than all of them put together.

Why? I’m not sure we know the answer to that. Perhaps because it is more directly in our line of sight than other repairs. The good news is a BMW windshield moulding replacement is extremely easy to do and will save you money by avoiding the dealership or repair shop.

If your windshield moulding is starting to deteriorate, you should replace right away to avoid more costly repairs down the line.

A BMW windshield moulding helps keep water and debris from getting caught between your windshield and the body of your vehicle. If not replaced you could end up with a windshield leak which is a costly repair to a BMW. It also keeps air from penetrating the seal around your windshield which can also cause leaking and irritating “whistling” sounds. If your BMW windshield moulding is starting to deteriorate, you should replace right away to avoid more costly repairs down the line.

The trick behind getting the moulding into the channel properly is patience. Try different techniques, whether light fist pounding or using a plastic trim tool, to get the moulding to seat against the windshield and create a nice air/water tight seal. DO NOT use any type of adhesives or glues…they are not necessary and will only create a mess. If you have any issues or just need a word of inspiration, please don’t hesitate to contact us at We will get back with you right away.
