I had a horrible smell coming from underneath the engine of our car. I took it in 5 times before they agreed to change the PTU seal out. The bottom of the PTU was covered in gear oil. They changed it out and it doesn't leak in that particular spot any more.
It doesn't smell anywhere as bad as it used it. It used to stink all of the time. Now it just stinks when you stop at a light or back the car up. The interesting thing is, I can't see leaking fluid anywhere any more... The ONLY thing I can tell is that it smells SO BAD on the drivers side wheel well just above the tire of the car, but it has no odor in the passenger side wheel well. Somehow this odor gets sucked into the car when you stop or back up.
Does anyone know where it could be leaking from that I would smell it at the very top of the tire on the drivers side wheel well??? And why I can't see any leaking fluid or dirty parts on the car covered with fluid?
