YIPPEEEE... FIRST ISSUE :
After the second free (15k kms) service, I suddenly felt my 90 hp has become very noisy.
I hear a constant drone as it crosses 60 kmph. Its not kind of a diesel engine noise but its a constant booming noise. If I remember, my car was very silent till 110 kmph earlier.
To check whether its an engine noise or some other issue, I took it to an empty stretch. The road is not being used by public as it leads to a dead end & then at 80 kmph, switched OFF the engine & yes, the noise persists even after the engine is OFF. Its kind of a thrumming/booming noise which gradually decreases as the speed decreases (even with engine OFF).
The noise is irrespective of the engine rpm or which gear the car is in. It starts at 60 kmph & then increases with speed. So I guess, it must be the wheel bearings.
By the way, discovered a new feature in the Punto. SURPRISINGLY, the brakes were working even after the engine was switched OFF. I mean I needed absolutely no pressure, the brakes were just like before.
I have read that in SOME cars, even after the engine is switched OFF, the brake booster does work, atleast for 2-3 times. I can confirm that in Punto, it does.
