Thank you for writing in. There is a strong chance an electronic component has gotten wet and has malfunctioned. It may dry and be fine, or the component may be damaged and need to be replaced. The fastest way to tell is to get the vehicle scanned for diagnostic codes. This will help you understand what system is experiencing an issue, and help you determine how serious the problem may be. Good luck!

When a check engine light comes on that could mean the system is detecting a concern. There are many possibilites of what it could be a this time. Trusting an auto mechanic shop who has the proper scan tool to see what code is present is a great start. They will have to take that a step further to figure out why the code is coming on. Example a code is only a discription and there could be many different repairs. There are many sensors within the vehicle. Bring the vehicle to get properly scanned to know for sure what repair is needed.

Check engine lights can be frustrating because they can mean so many different things, including any number of faulty sensors.  The only way to know for sure is to find a shop that has the scantool (computer) that can talk to the German cars, and have them read the full error code.  Not every shop has this tool because the German car manufacturers charge a premium for the software.  I would take it to a German speciality shop, specifically a VW speciality shop, if you can find one.  You will hae to pay for the diagnostic time, but they will be able to tell you what error code the car is throwing and why.  Good luck!
