Strange smell after driving and recurring error code P190D00

Hello everyone, I drive a VW Polo and have a problem that's got me a bit stumped. I have the error code P190D00, which points to a mechanical malfunction of the coolant pump for the charge air cooler. This error has been stored in the control unit for some time and keeps reappearing after a longer period. However, I don't notice any symptoms, except that my car smells strange after every drive. No warning light is on, the engine temperature remains constant, and there is no noticeable coolant loss. The fuses are all fine too. According to the error report, it should be a mechanical problem, but I'm not sure exactly which component is affected. Could someone tell me which component it is, perhaps with an OEM number so I can find it? And what could I do to solve the problem? Thanks in advance for your help!

Start by checking the electrical connections to the coolant pump for the charge air cooler. Ensure that all connectors are secure and free of corrosion or damage. Sometimes, a poor connection can trigger a mechanical malfunction error. If the connections are fine, consider inspecting the pump itself for any signs of wear or damage. Let me know how it goes or if you have any further questions!

Thank you for your answer. Where can I find the coolant pump of the charge air cooler? Can you give me a part number?

And what do you say about the smell after every drive? More precisely, in the morning the smell doesn't occur when I drive to work. There I drive down from about 1100m to 600m and back up to 1100m after work. Then, when I turn off the car, the smell occurs. Where could it come from and why does it occur?

The smell could be related to the coolant pump issue, possibly from coolant leaking onto hot engine components. Check for any signs of coolant leaks around the pump and hoses, especially after your drive when the smell occurs. If you notice any leaks, it's important to address them promptly. If the smell persists without visible leaks, consider having a mechanic inspect it further, as it could be a safety concern. Let me know if you find anything or have more questions!

The coolant pump for the charge air cooler is typically located near the front of the engine bay, close to the radiator or intercooler. Unfortunately, I can't provide a specific OEM part number without more details about your vehicle's model year and engine type. However, your vehicle's manual or a dealership can provide the exact part number. Let me know if you need further assistance!

Hello XxMxX, It is difficult to give that information. Please visit or contact the authorized workshop for the exact OEM part number. Thank you.
