I have a 99 c240 50k miles saloon. The fuel pump whines when the engine is running....it was replaced....still whines...1st pump put on my brother's car....no whine. Can't be pump...anyone know what this might be? sounds like 'neeeeeeeeeeeeeeeeeeeee'...obviously dissapears on over-run throttle-off.
As a 6 cylinder car, the engine is very quite, which makes the noise very noticable and irritating. car seem to run OK (excellent) apart from this.HELP!
(this is my 1st post on this site which i put in the tech area, but realised, I might be narrowing the field doing that...so I've added here in case someone else experienced the same problem)
