As we discussed in an earlier post, the Volkswagen Audi 2.0 TSI engines from 2008-2012 with engine code CCTA, CBFA, CAEB and CPMA originally came with an inferior chain tensioner. The aforementioned article discusses what the failure of this component entails and our recommended actions in order to avoid potential catastrophic engine failure that could cost you thousands of dollars.
In this article, we'll narrow our focus onto one of the persistent problems often associated with these TSI engine issues and discuss a specific part: the cam bridge.
What a cam bridge is
The cam bridge's relationship to the camshafts is that it's accountable for dispensing oil lubrication to them. Inside the cam bridge lies a very small aperture with a component, the purpose of which is to regulate oil pressure to the cam shafts. The screen in question prevents this component inside the aperture from dislodging.
Volkswagen Audi 2.0 TSI engine's cam bridge problem
This small screen inside the cam bridge screen often comes off, breaks, or gets stuck; which then leads to oil not making it to the cam shafts.
In the image below, you can see on the right the cam shaft with the screen that has come off, and on the left one with the screen in one piece where it belongs.
How do I know if my Audi VW 2.oT has a broken, jammed, compromised screen in its cam bridge?
The possible symptoms:
- your engine is stalling
- your engine is rattling
- check engine light is coming on
- low fuel pressure codes
- oil pressure light
But the only way to be truly 100% sure is to bring your Audi VW 2.0T into MINHS Automotive for a thorough inspection so we can confirm if this is indeed the problem causing the issues.
If it turns out that the screen is compromised in any way, we will replace it so your cam bridge looks like the one on the left-hand side of the image above.
