Gal ir nera, bet esu kelis 204hp 3.0tdi mates jau su barskanciais lenciugais, ir rida buvo 210-240kkm. Vokieciu forumuose taip pat yra siek tiek skundu apie lenciugo barskesius siam varikliui. (pasigilinus paaiskejo, kad ir 245hp kencia nuo to, 28 puslapiai apie barskesius ir automobiliai apynaujai)

V6TDI rattling noises after starting between engine and gearbox
Customer statement / workshop determination
The engine caused sporadic rattle or rales after the engine starting operation. The noise has disappeared after a few seconds.

Technical Background
The noise is caused in some cases by the chain tensioner for timing chain camshaft.

Series production
From vehicle production date 03.09.2013 of the optimized chain tensioner is installed at the factory.

measure
When the engine of the camshaft drive can transmit restoring moments on the chain.Thus, the oil is forced out of the chain tensioner and the tensioner retracts completely.
When re-starting it causes sporadic rattling noise will disappear after a few motor revolutions.

To make sure that the sound is caused by the situation described above, it should be addressed as follows: Please take the plug into the electrical connector to the valve for oil pressure. Thus, the oil pressure pump is always operated at idle with the higher of the two pressure levels. The increased oil pressure compensates for the leakage at the chain tensioner and increases the contact pressure of the clamping rail to the chain.

Now try to reproduce the complaint again with peeled valve for oil pressure.

If the noise is removed when the valve is no longer comprehensible, check whether the sound can be reproduced by reconnecting the valve.

Only when the correlation between the noise and the activated or reactivated valve for oil pressure, as described above visible, replace the chain tensioner for timing drive.
