318i Fumes

[BrianJrp]

Just got a 93' 318i with 63k miles
- noticing "fumes" after driving
- no big smell - but you start to feel it
- more noticable with sunroof/windows open
- also, rough idle this morning (wet rainy...)

Suggestions?
thanks...

Welcome to the board. When you say fumes, gas or exhaust? If it is the later have your exhaust system checked for leaks. If it gas it is even more important to have the fuel system checked for leaks. Can you isolate the fumes, under the hood, back of car, etc? Let us know and other too will offer some good advice.

If it's gas it's your fuel sender gasket.

could be an exhaust leak under the car too.. that same thing happened in my old 535is wasn't noticably louder but there none the less..

Check the fuel lines. BMW's fuel lines are known to crack and become very brittle.

could be an ecu issue.. that year e36 has an issue with getting water in the ecu when a body drain gets plugged up.. do a search on this subj

Most likely his has already been replaced (bmw actually tapes the old one to the bottom of the new ECU to keep it above the water).
