Help Please 2.0 TFSI Owners???

[arobson90]

Hi all, I have a 2012 A4 2.0 TFSI and have recently noticed a rattle / ticking noise coming from the engine as located in the below image.

I'm not sure if the noise was there previously and unnoticed or if it is a new sound. Anyone with a 2.0 TFSI who can confirm if they have this noise too?

Or anyone have any idea what it could be?

But most importantly is it possible to upload a video in the first place?

Fuel pump is back there. Runs off a cam shaft

Yeah that's what I thought. Couple of people on FB suggested chain, but I thought all the chains on this engine were at the front.

Cheers, that's what I thought.

Someone has suggested there is a chain connecting the cams together at the rear, is this correct?

I had the same thing on my Tfsi and was told by Audi it’s the fuel pump and injectors as the fuel is under extreme pressure and it’s the injectors firing.

Thanks for the response mate, I've heard that too. Just mine seems to have another rattle. I've had mixed responses from that's normal to a sticking cam valve to failing cat.

Yeah I had it on my 2010 model , only heard it when it was pointed out to me by a dealer when I was selling the car

Chain related would be towards the front font of the engine. I’ve seen camshaft/roller rocker failure and the high pressure fuel pump cam follower/roller failure. I’ve also seen cam bridge and vtc oil control valve failure cause rattle noises in the head but they generally have cam timing codes too. Just sharing not saying that what it is. Ultimately you’d have to take some things apart and inspect them.

Thanks for the response. I've managed to get it to a local garage and they believe it is just a valve sticking and nothing to worry about.
