Even an old school mechanic can test the exhaust and see if she's running rich or lean.
And all gas engines work the same way, regardless of heritage. ;- ) Test for fuel, air and spark. You need all three.
O2 sensors don't go out instantly. They usually fail over time. And even if they're unplugged, the engine should still run in some sort of "limp home" mode.
Does stomping on the pedal help it run a little longer? That could be a clue that it is running too rich. Or a host of other things, but it is a clue, at least.
Try finding an independent VW mechanic. That will be loads cheaper than the dealer. I think the dealers see "Touareg" and think all owners must be rich since they own one of these things. LOL!
And see my sig file. Now that I have one, I'm a firm believer that any Touareg owner should have VCDS.
No VCDS? Get it here:
