Hi.

I don't think that it is anything serious as the car runs perfectly but when i start the car at 4.30am (i'm a postie) it sounds a bit like the exhaust is blowing under the bonnet. This only lasts for about 45 seconds and does not upset the running of the car.

Any ideas, Thanks.:confused:

it's probably the auxillary air pump (which only opeartes when cold) getting noisy

:iagree:

At 10-15C is normal to make that noise?

Once a day at first start it`s OK?

What can be made at home or at service to reduce the noise?

On AUQ engine ??????
