This covers the basics of limp mode. I will try adding some pictures later on, but it has the part numbers for n75 valve replacements and some tips.
No vacuum line picture routing since it is already in the mk3 ecu hose/chip replacement writeup and linked from here.
Limp mode is basically when the car goes into a "safety" mode when it senses a problem that could cause engine damage. The usual cause is some sensor which is far out of it's correct range due to boost spike, vacuum leak, etc.
A key to knowing limp mode is that it is reset when you shut the car off and turn back on. Relatively fast power loss is the main symptom.
