My 2 month old Tavia vRS is quite noisy in the morning. Is it the tappets?

Also , on very light throttle, it seems to hesitate a bit. I mean when you are just maintaining speed so you are only slightly pressing the pedal. Is it the fly by wire throttle being at the start of the dash-pots travel?

Thanks

I had a similar 'tappet sound' immediately after start up and when I stopped at traffic lights after it warmed up.

The engine, as I understand, is known to be noisey, which I have read several places.

The noise that I had after it had warmed up and when at idle was the charcoal cannister venting.....to the inlet???? not sure :confused:. But basically it's a solenoid activating in quick succession stopping pressure building in the tank, if I understood it all. It's mounted on the drivers wing towards the bulkhead, if it's making a noise, you'll find it.

Hope I understood and helped you diagnose your 'noise'. It was driving me nuts wondering what it was!!!!

All 1.8T's are prone to the "Deisel-like" noise on start-up, but it tends to disappear fairly quickly, mine quietens down nicely within a few seconds

When you say 'In the morning' for how long do you mean? On first starting mine sounds like tin can full of nails but this lasts for 5 seconds maximum. Also mine will hesitate first thing in the right circumstances. My road is effectively a crescent, if I pull away from the house and drive around the crescent it will stutter slightly. If I do a three point turn in front of the house and go the other way it doesn't. I'm guessing that the extra manovering (sp?) gets everything flowing a bit better. Yes, 'technical' is my middle name.

Basically, it's done it since new, nothings broken, it goes like stink and I'm not bothered.

Good.

You get paranoid after owning an Impreza

I take it this charcoal thinky sounds like a slight "knocking noise" that sort of disappears sometimes and other times sort of varies in the speed in which it makes the tappy noise?

On mine i can only hear it when stationary and radio turned down but it does sound very diesely .

Yeah, it is a variable ticking/rattle at idle.

Easiest way to find out if it is that is to pop the bonnet ant place a finger or hand on the top of the cannister and feel the solenoid actuating.

It took four months and a mechanic stood at the vehicle to diagnose it!!!!

You may also notice a "turbine" (not turbo...) whine plus "blowing exhaust" noises for a minute or two after a cold start.

This is the secondary air injection system (thanks to Dave - Skodaw - for the explanation). It is a fan which blows air into the exhaust stream so that (a) the catalyst can burn off the excess fuel from the over-rich cold start mixture, and ( in doing so, the catalyst reaches operating temperature a bit faster.

It shuts off when things have warmed up a bit.
