Hi folks.

We have an Octavia vRS 1.8T, 53 plate. We like it a lot - it is cheap to run and insure, surprisingly quick for an everyday estate car, and reliable. However, I've noticed a couple of things which I ought to get checked out, and will, but in the meantime thought I'd ask here just in case any experienced owners or specialists are lurking around...

The main thing is that, from cold, there's a definite tick-tick-tick from the engine. It's only really noticeable when cold, and largely goes away under a bit of moderate revving, but it's a little bit worrying in as much as it didn't do this a couple of months ago and I'm wondering if something is wrong. It may be nothing but if anyone has had this occur to them (either with this model or one of the VAG siblings which share the 1.8T) then please do say..

Second thing is that first and second gear are a bit 'choppy' in regard to the way that they deliver acceleration at lower revs (say 1k to 2.5krpm) - it can be a bit flat at a given rev, or it can surge ahead, and it seems uneven and inconsistent. This is most noticeable from cold, but is still there once the engine is up to temperature (albeit to a lesser degree). That said, the engine doesn't appear to be down in power and economy remains roughly as it's always been.

I'm wondering whether either thing is just a symptom of a car getting older (it's sitting at 48k right now, and was last serviced in November, so it ought to be okay).

Any thoughts?

Thanks,

John

Oli.

Give it an oil change with a decent flush first. And run and injector cleaner through and then give it a good thrash - I would recommend FORTE products, should help/cure both problems

Our old A6 1.8T used to tick when it was a little low on oil

all sounds pretty standard to me for the engine the tapping is the same on mine and the flatspot is a common issue which my remap seems to of pretty much removed.

might be worth popping over to briskoda and having a look around.

The tapping / ticking noise is common on 1.8T's, its a valve on the vacuum system.

The flat spot / choppy power at low revs could be MAF related.
