1999 BMW 540i Q&A
1999 BMW 540i Question: Hot rubber smell coming from engine.
I have a 99 540 with 70,000 miles. The car has been very well taken care of. After driving, a hot rubber smell comes from the engine compartment. It does not smell like hot oil but rather hot rubber. I noticed that the power steering fluid reserve had leaked somewhat. Could that be causing the smell? - 99540
one of your pulleys is freezing up - brhudak
What your smelling is probably your belt. Have it inspected right away or going to leave you stranded. Like answer #1 something binding up belt. - rpclements
