Hi, looking for some knowledge please.
Just picked up the 14 plate from its 24k mile service and the BMW chap told me that the exhaust flapper valve had “seized”. They managed to free it up and sprayed it with WD40 so it’s working at the moment but that won’t last and it will seize again.
My question is: If I take the cover off and spray it with WD40 on a regular basis will this keep it working okay? If so how often do you think I need to do it?
Many thanks
