BMW 525i Oil Leaks From Lower Engine Area
BMW 525i Problem
Average Mileage: 110,305 mi (69,000 mi - 170,000 mi)
Happening to me now
This is just one of many problems had with this car after 4 months from purchase. I did the research on them and thought was buying one in good condition but it has spent more time in shop than road and very costly. I'm hoping in the long run I will have it long enough to off set some of the cost. They are a dream to drive but I must be one in a few who have major problems that takes away the fun after spending over 3k already and still waiting for something else to go wrong. I sold my 2004 Impala that I had for 3yrs and no problems to buy this and it's been a nightmare. We had 3 BMW's before and I swore I'd never own another one so I got what I asked for because I missed driving them.

Leaked while in park with engine on and then kept getting worse over time.
Fixed by replacing oil pan gasket.
