Get a pierburg if you can for the water pump. They’re more OEM than Mehle is for water pumps even though both are OE manufacturers.

Pros: more OEM

Pros: worked fine for years

I kind'a have some project and I need to use Pierburg CWA50, all I got in my country is this pump from benz (**A0005001986**), is it same model as Pierburg CWA50? Because the head pump is same but the connector is different (facing upwards). I tried to find specs from this model, the result is empty, can't find any clue about flow rate. I do have original code from Pierburg, which is **7.04933.56.0**, but can't find flow rate either.

Part number: A0005001986

when my original pump went bad, i went to Peirburg so that the plastic housing wouldnt crack. Pump lasted about 20,000 miles, bought another one from fcp euro for the lifetime warranty but this one lasted 20 mins before i got those same codes and overheated.

Cons: short lifespan, immediate failure

Mileage: 32187 km
