Middle follower... been in a car (audi a4 2.0T DTM) for 5k.  :scared:

What would cause that?

This is a pic of the cam itself.

Any ideas?

Has that HPFP been uprated?

Yes.. just waiting to hear back whether its APR or internals. (im guessing its internals)

Is that cam smooth to the touch?

U can tell wether its an apr or just internals by looking at the size of the piston inside the pump. Apr has a larger one and is machined out.

Ahh... this might have been the reason!!!

Rev. A camshaft.

I'm afraid it's not an uncommon occurrence.

I had to replace a cambucket at 3000km's. There were some bad cam buckets rev F I think that was problematic. But other cars I have seen no wear at 15000km's with APR pump as well.

But I guess it most likely will end up being the Camshaft if I'm not mistaken.
