This embarrassing moment was a case of me acting in my normal impulsive self. Rushing in........and paying for it later.
The Scene is Wombat State Forest.
David Danks had taken us on a little diversion to look at a "sawdust mound" but had become bogged. There were 2 ways in so I said, "I'll just drive through that small puddle to get in front of you and pull you out."
Now the Disco had exactly 524km on the clock and no snorkel.
I went in the first time, almost got bogged but managed to back out. I then decided to give it another go with a bit more momentum. This managed to butt a wave of mud halfway up the windscreen.
I backed out, david winched out and we continued. About 10min later the car was running like a dog (or like a diesel take your pick)
We pulled open the airbox to find it full of water and mud. After a bit of mucking around we found it did not run with the MAF sensor plugged in.
We unplugged it and drove home with a piece of cloth instead of an airfilter.
I now have a snorkel!
