I can see nothing under the bonnet, can anyone suggest anything? cheers |
Carly,
You mentioned 2.0 petrol, is that "regular" gas or higher? You might try 89 or 91 octane gas and see if that helps. I use 89 and a gas additive called Lucas and it has helped quiet the noise and smooth the ride with 199K on the odometer.
Also you state you have 10,000 mi on the clock, are you still in warranty? Because, if so, a trip to the shop shouldn't cost you anything.
