General repair problems
I have 2 general problems.
- When I start my 190E and turn on the air conditioning, there comes a very loud e...e...e...e... noise from the front. The noise stop after I drive for half a kilometer. If I stop and engine and start immediately, the noise does not happen. It seems that the noise only happens after the car has stopped for a few hours and only when I turn on the air conditioning.
- I replace the tires, but with a incorrect thickness. 60->65. Will this affect the speedometer to produce the incorrect reading? or the difference is negligible?
