The tfsi is far from the smoothest petrol engine at idle. Its probably normal. I couldnt say for sure without hearing it.

thanks for the reply....

but would I be correct in saying that all mkv gti cars have a diesel sort of sound at idle ?

great, thanks.

1 other question, a bit off topic:

the car has been remapped, and I will be bringing it to a main VW dealer for a DSG service very soon...is it possible that if they try to update any software etc, that this could overwrite the remap? i.e do i have to tell them the car is remapped, and not to load any software onto the car?
Cheers

Get your DSG oil service at Geos. He is cheaper than any main dealer and you are getting an experienced mechanic with the proper tools, you never know what you get at some main dealers

Some GTI's had a campaign that required an updated map to be flashed by the dealer. This would wipe your remap. You could tell them not to update the ecu. Most tuners would reload the map for little or nothing as they would have the map on file.

just an update,

bringing the car to a dealer tomorrow and will get their opinion on the engine noise. The knocking/ticking noise only appears at idle and only when the engine has warmed up.

I found this you you tube video which demonstrates the noise, however the one in the video seems a lot louder than mine, but the same type of noise. If you lift the hood on mine, you can hear the noise louder, maybe this is recorded whith the hood up with mic rite next to the engine...but from inside the car/or outside with the hood closed, the sound is similar but nowhere near as loud as the video.

If anyone is familiar with the sound of tfsi engines, could they have a listen and give their opinion? Thanks.youtube tfsi engine sound

Hi Kevin,

so is this not the normal noise for a 2.0 tfsi? I have done a heap of searching, and nearly everything I have read says that it is very normal for the tfsi engine to make a 'tock tock tock tock' noise at idle, and that this is due to the hight pressure direct injectors..which have a similar set up to a diesel engine..

Mines been doing it for nearly three years now, always serviced and had the timing belt done last week. No change, and garage has always said all the mkv GTi's he has worked on has been the same. My forge twintake has just arrived at keiths so I'm hoping when I get it tomorrow it might drown out the tock tock tock!

Hi Joe...

yeah well same with mine..nowhere near as loud as that, but its the same type of sound,does your car make a similar sound(but no where near as loud)...as in a tock tock tock tock, when the engine is warmed up, at idle?

To be honest I've never noticed it. I've never thought "oh, my engine seems much louder than it should!". To me, it sounds normal, louder than a 1 litre Yaris for sure, but I'd expect that.

Christ.


The tfsi are known for being a bit dieselish on tickover, but that sounds way too loud imo.

Could just be the recording though.

Your wasting your money going to the dealer to be honest. They're all a bit noisy at tickover. If it drives well drive on and enjoy.

He said he's heard plenty of noisy gtis , said he did a load of tests on the engine and that's everything is good...basically said he could strip down the engine and search for the source of the noise but said I'd be mad to do that..said it's just a characteristic of the gti..and to leave it be...
