[Vwdiesel] *CEL light on middle of road trip*

[Rolf Pechukas]

ok, so I had the code pulled at AutoZone
CEL is on b/c "EGR excessive flow detected"

(reminder: 2001 Golf TDi, smelly exhaust, CEL, recent shop error alternator replacement forgot intake hard pipe, 30 mi driving w/ turbo disconnected)

now I don't understand these fancy TDi's at all
but my simpler N/A mind sees 'excessive exhaust' and thinks 'burnt valves'

is this just a matter of faulty EGR valve? possibly caused by unfiltered intake air? driving 'hard' (shop suggestion to 'reset computer')?

any other thoughts on this result?

thanks for all the input,

Rolf in MA


> You should have them pulled sooner than later; but I wouldn't allow it to ruin a drive.  Nor would I be unduly bothered by waiting a few days.  "Serious" faults will trigger an idiot light: oil, temp, ABS.  OTOH, if the CEL is blinking, then it is serious, and you shouldn't drive it.  [At least that is what I think the manual said.]  Just find out what is causing it before the next inspection, and get it fixed between now and then.  There is a good chance that you can ignore it, once you find out what the code is, and have it repaired at your leisure.
