lighting problems

[nyemba]

hi guys

I am new to this site and Mercedes world.
I got a Mercedes E280 2006 model diesel,the engine is sound ,but the lights- rear right,rear left ,brake lights just came on the dash and i checked them and all are working fine ,it says second or reserve light is in use.

the wheels mainly left make a hissing noise as i increase speed.

what is the problem and am i in for big cash to spent.i live in uk.

your help is highly appreciated.

Check for broken wires in the boot hinge.

Check the suspension and the tyres for feathering.

Mercedes have a clever system with many models so if one rear bulb fails for whatever reason it will use reserve lamps instead. So you need to check all the rear bulbs are working.
As to the other issue with the hissing noise with the wheels you may have a wheel bearing needing replacement. Jack the car up and spin each wheel and listen for a noisy bearing.
