[video] TDI V6 ticking noise

I'd like to know where this ticking is coming from, any ideas?

What kind of oil are you using? Is it the VW507.00 spec? It sounds like a lifter or injectors. Is it due an oil change now? If so, do it and see if its still there or goes away.

Lifters would be louder than that, wouldn't it? I bought the car used and it was making that ticking noise since I own it. I always put VW507.00

Previously I used the castrol edge 5w30 (vw 507.00, bought at dealer), now I just changed the oil today and i've put the VW OEM 0w30, still no change to the noise.

I have a Q5 with the same engine. I popped the hood when I got back to work after lunch and mine sounds just like yours. It has 75k miles and if good shape. The clicking was coming from my injectors

 

[jorioux]

Have you replaced your injector seals yet?

 

[joep1234]

Haven't done anything to mine but did all of the service to get everything up to date. I don't have any issues with fuel, oil or antifreeze being where it shouldn't. If it were to be a problem, my car still has 45k miles of the extended diesel gate warranty.

Hard to say if its fuel injectores or not? if it starts right up on cold/hot i would rule them out could be something not getting oil me personally i would do an engine flush using a product like BG EPR or Moter medic 5 min synthetic engine flush.

 

[jorioux]

The engine always starts right up, so that rules out the injectors.

That means it would probably be the lifters. After changing oil to 0w40, I noticed less ticking noise, but it's still there. Should I use seafoam on the 3.0 TDI ?

If it were mine I would try an engine flush additive like seafoam in the oil (if its lifters), and/or some Power Service Diesel Kleen in the fuel (if it's a loud HPFP).

I bought a liter of Power Service Diesel Kleen at Canadian Tire store, and poured the specified quantity in the tank and after consuming the whole tank, the ticking from the HPFP is almost gone. I will definitely pour some Diesel Kleen on a regular basis.
