Q&A

Right at 100,000 miles at a routine oil change it was noted that a large amount of oil had been leaking under plastic undercarriage. I took to my Mechanic who said it was a big job requiring about 15-20 hours of labor. He changed oil gaskets (?) drivers side, passenger side and center. Mechanic test drove, said the driver's side was still leaking and replaced the seal once again. The car was returned and is STILL leaking oil which seams to be coming again from the driver's side. Large spots of oil on my driveway each morning. Paid nearly $1000 and the repair took forever, not so eager to bring it back to this mechanic to fix as it appears not to be what the initial problem was, if he truly replaced the seals in the first place. Does anyone know of any problems with the 545I with regard to oil leaks? I purchased my car about a year ago at 95k and have only driven it about 5 months till it reached 100k and have not driven it since, it has lived at the mechanics shop and has sat in my driveway leaking oil since its return. Any advice would be appreciated!
