Passat VVT device on inlet cam??

[gkm24]

I have a 52 plate Passat 2.0 ALT engine code(5 valve per cylinder). It is a twin cam engine with the cams linked by a chain. There is a device fitted on the end of the inlet camshaft that looks like a variable valve timing assembly.
How on earth does it disconnect from the camshaft? My Esawin is not working on my pc and im desperate to get the car back on the road. Any advice greatly appreciated.

It is just very tight, 80Nm + 90 degrees which is around 100Nm. You MUST use a new bolt, part number N 105 216 01 which is £2.94. If you re-use the old one it is highly likely to fail and destroy your engine.

Thanks for the reply but there is no visible bolt etc that connects it to the camshaft. How is it connected? The part that i am referring to is on the bulkhead end of the camshaft. The part number is 06B109088C if that helps.

Anybody???

There is a Torx head bolt in the centre, T45 if I remember well. 06B 109 088 C is now 06B 109 088 D and costs £391.22 if you damage it. The bolt in the centre is VW part number N 105 216 01.

Whoa, you certainly come up with the goods. I will take a close look for the cap in the morning. Thanks so much.

[gkm24]

Had a look this morning and there is no cap??? In the diagram I can see that No2 passes through the gear(No3) on the end of the cam and bolts that on. How is No10 connected to the camshaft? There are 3 bolts (No 5) that hold the housing on but if I undo them
the housing (No 10) will not pull out of the camshaft.
There must be some sort of snap ring or something but I cant see it and as you said, its an expensive piece if I break it.
Hate to say that I am a qualified mechanic but just cant see how this fits into the cam unless its stuck in it!!
Thanks for your time in answering my problem.

The N205 control valve item 10 bolts to the head and just comes off after removing the three bolts.

[gkm24]

Thanks for your help. Don't know whats going on with this one as it will not come off. I will put it back together and hope that all is well.

Hello gkm,have you find a solution ?

I have an Audi A4 2.0 20v ALT engine, but after have unscrew the 3 bolts, it's impossible to unplug the n205 valve...

thank you
