I have the same attachment as you. I've only used it twice, with very disappointing results. It is not as well built as other foam lance attachments, just do a youtube search for foam lance and karcher foam lance, you will see a very big difference. Others get snow, Karcher gets melting snow, if you get my drift...
Also, based on my previous searches, Megs Ultimate Wash and Wax doesn't create as much foam as other shampoos.
Try using very hot water when you mix the soap solution, dont shake before you close the top, and don't shake too hard because it freaking leaks! And lastly, play around with the dilution.
I gave up after realising i use 5X the amount of soap with the foam lance vs normal 2 bucket method. Maybe when my kid is older i'll bring it out and have a snow party... or a melting snow party.

step 4 last use M115 for final clean and buffing

You probably meant D115. Meguiars recommends to use on a dry surface, to prevent further dilution of product, saw it on the Megs forums somewhere.
If you're worried that the car is too dirty, skip the D115 and do a 2 bucket wash? But honestly the D115 can be used on rather dirty cars, just use it wet by spraying more product and use lots of towels.
