TFSI 2.0 EA113 Oil pressure – Part 4

continuation of troubleshooting the oil pump of the TFSI 2.0 EA113

All right, we are back. Let’s start out where we left off. The oil pressure regulating system. So far we have learned about the different issues associated with it.

  1.  Wear in the bore causing leakage
  2.  Wear in the bore creating a ledge for the piston to get stuck upon
  3.  Debris making the piston stick
  4.  Clogged up oil suction pipe forcing the piston to open

So what can we do to fix or prevent this? We have a solution. The Wasa oil pressure fix. For many years we have fixed this problem for customers in Sweden, using a rather primitive solution. Not very scientific but absolutely good enough to get the cars up and running again. It was only when we started thinking about going worldwide with this, that we scrapped the old design and started working on a new one.
The goal this time around was to fix all of the above mentioned problems at once. And we did.

The new regulating valve uses materials that work together in a way to reduce the risk of debris getting stuck in it’s mating surfaces. The positioning of the ports are no longer forcing any angular forces to the piston and a clogged pickup won’t open the ports.

More about this nice little oil pressure fix can soon be read on the dedicated page. Meanwhile here is a link to the product page.

The oil pump itself

As you may recall I stated in an earlier part, that the oil pump itself seldom fails. This is true but while you’re down there it of course doesn’t hurt to check it. We have found that most damage tends to be found in the pump cover / lid. Although the pump can take a lot of damage before causing issues with the pressure, the lid can very easily be machined. Just to get that little extra peace of mind. The rotors of the pump often show signs of wear, especially after chain failures, but it rarely affects the oil pressure enough to be noticed. If you feel nervous about it you’re welcome to sen us pictures and we can help you assess the situation.

Coming up next

The previous part was a very long one. This compensates by being very short.

In the next part we will take a look at some bearing as well as learning something about piston cooling jets. Not only will we talk about oil pressure in that part, but we’ll also touch a subject well known to TFSI owners. The oil consumption. See you all then i hope!

      Thank you! I will write a part whenever I get the time. Hopefully the next one will be within the next two weeks.

    Very nice information!
    I have a question, did you eliminate the movement of the valve with this piece?

      Hi Robinson,
      The valve still moves, but is no longer subject to the side forces from the ports, which accelerates wear in the OEM.
