Spilled coffee in shifter and will not shift out of 2nd gear on 1999 Mercedes-Benz E300

A girl friend has spilled coffee in the shift lever area and now it will not shift out of 2nd gear. I am a Jaguar tech but not much experience with Mercedes Benz. She said a repair shop said the "valve gear" is bad, part# 140270060688. Any help?

I work on Jaguar as well. I had a similar problem with a friend's VW, she spilled coffee in shift lever area, shift lock solenoid failed, may be worth taking apart shift console see if you can see what's wrong. Have you ever used Alldata ,You can get a one week subscription or year subscription very cheap,
There is a professional service called Identafix. They only deal with professional repair shops. They are in the Minnesota 651-633-8007.

Thanks Patrick I will give it a try!
Buy a new one. Super easy to replace. I just did mine because it burned out, literally. But it was very humid and I think I might have spilled something on it a while back. This is a very common mistake. I dont use that cupholder anymore!
I youtubed how to get the console out, then the shifter is 4 bolts and a clip for the linkage and your done.
good luck
