09 gl320 3.0 blutec p2463 code high soot level runs for about a minute then dies.disconnect lines to dpf sensor no change,dpf regen no change and code will not clear

Shove car over cliff
problem solved

I wouldn't think a high soot level code would kill the engine... maybe put it into limp mode? But I'm not sure. Disconnecting the sensor doesn't help - it will basically just tell the computer there's an issue. The fact, though, that the code won't clear means there's still problem. Doing a re-gen doesn't mean the cat is clear and good. Look into some way to see if you can figure out if the sensor is bad and/or maybe needing a new cat (or some type of electrical "code out").

You could have more than one thing going on - but get the DPF code figure out, first.

When it dies out, HOW does it die out? Stumbling like running out of fuel? Or more like turning a switch?

thank you dpf sensor tested ok the dpf is plugged i assume the vehicle only has 102,miles thought you would get more out of the dpf.runs great dies like turning off the ignition .thank you

Absolutely you could more than 102K miles - but there's way too many variables about how it's been used and maintained to say.

I'd start by going through battery connections - at the battery and the engine - and look for ground straps. Make sure they're clean and tight.
