BTDT- Was RE: [200q20v] Mysterious Stalling

[Forhan, Thomas]

We've got people talking about two seperate problems here, one the "classic"
stalling as you come to a stop, which often indicates as Paul says, a turbo
bypass valve. The second situation is a complete cut out when crusing- that
seems very different. 

In both cases, the first thing to do is pull the error codes: Chris pages
link to Scott Mockry's excellent directions make this so easy you can do it
in a minute- you just need to go to Radio Shack and buy a diode with a
resitor already in line, and Office Depot to buy a paper clip to serve as
the jumper.

Mine was the turbo bypass valve, stalling as I came to an intersection,  and
I also had low boost - about .3 bar below previously highest readings. Ether
way, download those error codes- they are a real help.


Good luck, 

Tom F.
