If your car is leaking coolant, this may be the cause. I recommend changing this component only in authorized garages. Part code 17138616418 Aprox 100$
1:39 this video is fantastic thanks! One thing to clarify: at this point of the procedure you need to insert a flathead screwdriver on the top side of the tank, where the tank’s mounting clip attaches to the frame, in order to release the locking tab that holds the expansion tank into its mount. It would be good to have video showing this part. it’s not entirely clear from the video but I eventually figured it out. Great video though!
