Little help to put my mind at ease please - DV replacement

[nc35]

Hi All

Well spent a good afternoon on the car doing loads of work I have been meaning to do for the past few months.

The main one being replacing the original DV.

Well on the left is the original type "B" and the new type "D" on the right.  Is this right or is there bits missing from the original? 



The second picture is just to show I haven't left anything behind!!!!



The new DV went on without a hitch, and the engine has started, but throughout the afternoon I have become more and more paranoid.

Can someone please put my mind at rest before I take it for a test drive.

Thanks in anticipation.

The "D" type replacement looks fine. Looks the the top of the "B" type is missing.

i would be pulling the new one off asap as something has come off the old one

I have had a good look in the "hole" where the old one came from, before fitting the new one.  There is deffo nothing left in there.

This is my worry that there are bits floating around in there that shouldn't be.

Going to nip out and have one more look on the floor under the car etc. 

At the moment I think the bit has been missing for some time (possibly since new)

Would I have known?  Never driven another GTI to compare.

Have a look on the back of the wishbone to see if it's dropped off and sitting there. I constantly dropped the allen key and it always ended up there.

Yep just had a look, no sign of it anywhere 

Thanks for all your replies.

Can't believe it's been missing since the factory.

I'd imagine it is going to drive like a different car if it really has always been missing

It can't have been missing from the factory or your turbo would not have worked at all!

The end must have fallen off when you removed the old dv. As mentioned above, I kept dropping my allen key and could I buggery find it again. It took ages to find it with a magnet on an extendable pole. I though the cay had eaten the allen key!

[nc35]

OK

Been under the car again. No sign of it anywhere.  I think I would have found it. 

I am also 99% sure that it wasn't there when I took the old off. It wasn't a case of dropping the old DV I had to ease it off. The inside of the old DV even had traces of oil ,pics taken after I cleaned the oil off as I was looking to see if anything was broken.

Are you sure the turbo wouldn't have worked? Thought the dv helped it spin up easier from lower revs?
Really weird.

Think I will take it for a test run tonight before the work run in the morning.

What was the reason for changing from a B to a D ?

Reading this forum 

keep reading the other versions fail.

Don't know what symptoms to look for.

If there's no dv (or a broken one), the turbo pressue will be venting and therefore the turbo will have zero boost (hence not working). You would hear a constant hissing as the boost pressure is always being released like it should when you lift off the accelerator.

The B is VERY weak and fails (mine did). There is a rubber diaphragm on the B version that splits after a while and you lose boost pressure. The D version uses a piston and is much stronger.

Well now you mention it - "constant hissing", Yes, thought that was the Turbo spinning up... 

And no "push in the back" when the turbo comes in.  Just thought the engine was really smooth for a turbo.  Used to get a real kick when the KN-TT came on song, but kind of expected that.

Test drive over.

Car transformed. 

You can now tell the car has a turbo. Can also understand why you guys fit WALK kits.

Truly amazed by the difference.  Thought it was quick before.

Just wonder what happened to the rest of it.
