You are probably better off bringing it to the dealer. The 140 clusters are as tight as the 129s. The dash hooks required to remove them need to be bent at an additional angle to get a good grip on the housing.It is very easy to break the housing and lens trying to pry it out. Not to say that it cannot be done at home, but it can turn into more money than expected. The bulbs simply twist out of the back of the cluster. I would buy the bulbs from the dealer and replace them all while you're in there.Probably get charged an hours labor. Good Luck.
