N205 valve replacement on Mk6 GTI 2.0TSI (EA888) engine

I thought so but wasn't sure.

So what is the servo for the tumble flaps doing during all this?

Didnt look that closely

I just realised what it is - its the gearshift connector moving on the gearbox as my wife shifts the car into neutral and flicks the gear lever from side-to-side. Look closely and you can tell.

Hahaa watched it again on desktop. That's perfect view of the selector.


By the full mark on the dipstick are you setting it to the top of the mesh or the step on the stick?

When the car is warm after about 10sec from engine off the oil should be at the top of the little mesh on the stick. After about 5min roughly it should be almost at the max ( the step).

If you are setting the level at the step when checking it after turning the car off there is too much oil.

Hence you can get abnormal noises on startup after long off periods from the oil been 'slapped'

Haven't really found any evidence to say that long term damage can occur as its only for a few seconds during that initial oil build up but cars with oil level sensors activated will get check oil level warnings when the oil is at that level for been overfilled

^ oil level is kept to the top of the criss cross hatched pattern on the dipstick. Just checked the oil again this morning and it's all good.

If that's were you set it then that's good. Based on the video and what you have. Said your car isn't making any abnormal noises on. Startup

Tool?

[Lucas_R]

^ appears to be. Bugger that ones 1/2 the price i paid for mine.

Pulled the N205 valve out last weekend, sprayed it with degreaser and then soaked it in petrol for a few hours. Everything looked clean and in good working order upon inspection. There was no debris etc in the valve that was hindering its movement.

Re-fitted the N205, no issues. Car still rattles on startup so the valve had nothing to do with it.

If any of the mechanics on here wants the special tool, let me know.

Did you ever get a resolution to this noise?

[Lucas_R]

I believe its a stretched timing chain and im looking into getting it replaced as the noise is annoying/embarrassing and im looking to sell the car in the next 12 months or so and any potential buyers will be turned off by that noise (rightly so too).

I have the same issue, new tensioner fitted and running fine but will rattle for 1-2 sec if left over night. 55km on the engine
Thought it could also be some kind of non return valve which is allowing oil to drain back to the sump.

[vert1]

It will be the chain, changed mine over christmas and you could see where the chain had been slapping the timing cover.
Noise is gone and back to 7 notches exposed on the new style tensioner where as I had 10 before.
Early chains are prone to streching so should be replaced.

After a long time with this problem, which was aggravated by the increase in noise, it was discovered that the root cause is the Camshaft Bridge, where the screen breaks and the non-return valve itself bursts into several pieces, which ends up going to the phase variator of the command going to the cylinder head and the catastrophe turns fact.
Where it is not normal if there is some noise when starting the engine. If you hear you can check the part right away.
And when installing the new Camshaft Bridge remove the screen immediately, leaving the path clear to the oil for the non-return valve and go for the intake camshaft.
