(Audi) CWA50 to CWA100-3 Adapter Kit

A bundle consisting of the Pierburg CWA100-3 water pump and an adapter cable to easily change out an existing CWA50 against the newer / stronger pump.
Useful especially for Audi vehicles with a standard CWA50 intercooler pump.

Attention: Experimental Product!
We offer this product on the request of some customers but it is without a 100% guaranty for working on every car.
It seems to work fine on some cars. And on others it does not .. quite. (see the explanation below)

Explanation:
The CWA pumps are speed controlled by a signal from the cars ECU.
Some vehicles seem to be compatible with the CWA100-3 but others seem to be not.
In other words: On some vehicles speed control works and on others the pump is always running at full speed.

Unfortunately, we are no Audi experts and can not say for which models that is the case or not.

But if the new pump (with our adapter) does not start at all you can also run it full speed all the time by snipping the adapters signal cable (gray/red).
With this the CWA100-3 will run at full speed as soon as it gets power.

Liability:
Please use the product only if you know what you are doing.
We cannot be held liable for any errors or damages in any form!
Especially when it comes to damages on your car, engine or the product itself!

Pierburg CWA100-3

The CWA100-3 is a successor of the CWA100-2 we are also offering. The dimensions and the weight are nearly the same.
New is the freshly designed impeller housing with slightly shorter water in and outlets and the bigger electrical connector.
This improves the handling of bigger cable diameters significantly.
Suitable for instance for intercooling in combustion engine vehicles and cooling of various systems in electrical vehicles.
