Last I drove the wagen I lost boost a few miles in. Got to my destination, turned her off. After restart I had boost all the way home. I stayed on boost (like over 2500 rpm) the whole way. Wife drove it today and instantly no boost with EPC/CEL. She doesn't drive in "manual" mode, I do.

Does it seem like the voltage might be off? That sort of WG issue? Everything was supposed to be set from HPA and has worked great until now. Maybe the lock nut came loose?
