Low rev stutter

[Rudeboy99]

Hi out there in rocco land I've got a 09 2.0tsi and at low revs under 2grand it's quite lumpy and stutters when cold the problem does improve after a run and above 2-3 grand it's just perfect. Any ideas would be a great help as after being plugged in no faults are showing or logged it's had a full service plugs etc I've just bought the car after loving them from a distance and hope it's nothing hugely expensive

What sort of mileage has the car done?

It sounds like an issue mine has had. If you look at my some of my previous posts you may find the problem familiar. I had diagnostics done twice and both times it came up with nothing.

My issue was carbon build up which is a trait of the engine. Mine seemed to be mainly around the inlet valves. The Audi TFSI lump is the same.

I tried a local carbon clean company and this seems to have improved the situation. The alternative is to have a garage remove manifold and clean manually but this could cost around £300. I tried several fuel additives but was then informed that as the engine is direct injection these won't touch the inlet valves! On the plus side i have a very clean fuel system. I've also been avoiding supermarket petrol stations and only using the super unleaded high quality stuff.

Hope this helps!

I did see your posts dude when I did a Google search under engine stutter I agree that the best fuel is worth it I guess and am booked back in next week so will mention the carbon build up to the boys at the garage .it did seem a tad better after the full service so plugs were probably knackered aswell but I want to get it sorted to fully enjoy the car which apart from this I absolutely love to bits . What fuel cleaner did u use bud ?

BG 44k Power Enhancer Fuel System Cleaner and a Wynns Fuel System Treatment i got from Halfords. I also changed my plugs when i first noticed this issue.

Yesterday i used a company called Engine Carbon Clean Herts who did a hydrogen gas flush of my engine and it seems to of improved my issue. They are a mobile service on facebook in the Herts/Cambs area of the country. I thought i would try it before stripping off manifolds etc.
