Hi guys. Was out in the car today and did a 200 mile round trip. I noticed that when you come off the accelerator and the revs start to go down there is a funny rumbling/vibration almost grinding noise coming from the engine, well i think its the engine Its not really loud but is very noticeable. The mrs said she started to hear it a few days ago.
Its quite hard to describe but like i say it sounds like some sort of light grinding from inside the car. The car is driving normal and there are no fault lights etc.
Does anyone know what it could be?
I was wondering if this could be driveshaft? Or bearing related even though it doesn't sound like its coming from the wheels.
The front discs and pads, and timing belt and water pump were both done in the last 2 weeks if thats any help.
Car is an Astra G 2001 1.4 16v zi4xe
