Does anyone know if the mb factory w126 service cd-rom set includes detailed info on engine, transmission, and fuel injection system? thank you!!

i bought cd service manual for my w124, and it includes step by step on all service and also diagrams and detailed information on everything. it takes up two full cd-roms, one for electronics, engine and trans, and the other for chassis and everything else. im sure it has everything you need. Find a cheap set on e-bay. i got mine for $11.
