Repair or rebuild B5wsc?

hello

Since I unfortunately damaged my auxiliary heater along with the car, I now need a new plastic cover that includes the water pump. Does Bosch sell it for €160 plus VAT?

Okay, since there's not really much space where the exhaust needs to go, I was thinking about buying a supplementary heater and installing the heat exchanger housing on the B5. That way, I can save money on the expensive cover and instead buy a water pump from eBay. The problem is, will everything fit together because the supplementary heaters only have 3 or 4 kW of power?


If someone can get the parts cheaper, that's good, and then they might be able to earn a few euros .

Best regards,
Marc
