Ml320 99 lpg conversion
my 1999 ml320 has had an lpg conversion for 2 years, and up to last week was running fine.
Over the course of a week it began to feel more and more underpowered, both on log and petrol, until one day it barely started and when it finally had it ran weakly and hesitantly on lpg.
I've changed the MAS for a genuine Bosche part, but it still won't start up. To add insult to injury the battery has become flat ( a combination of beating oft sitting for a week and my overzealous attempts to start it up)

Have I jumped the gun in getting a new MAS ?

What else might it be ?

Any time you replace a component without first reading codes or diagnosing the problem you've jumped the gun.

These used to be common for trouble with the cats blocking up. If you want to try something you could remove the lambda sensors and see if it starts.

Yep. Cats crack through thermal shock from driving through puddles then break up and block.
