2012 bmw active hybrid 5 hydrolic problem
 

Hi there guys. I have a question.
I have tapping/ ticking noice coming from the engine area.i did get it diagnosed and got told my hydrolic lifters needs replacing but when I'm asking around for garages I'm getting all sorts of prices with a big diferance.im baffled about if the high price is trying to knock me or isit the low quote that I'm getting they are misunderstanding me orrr what.has anyone ever had a problem with there hydrolic lifters,if you did, what is done to sort it out ?
