It sounds like regens can [normally] range anywhere from 200 to 500 miles. I put the soot gauge at the lower right side of the first screen. When it gets around 2.60-2.70 it'll go into regen. But something to consider, the soot number will change both up and down depending on your driving. Press and release the clutch pedal. Hold the DPF switch to the ON position for five continuous seconds then let go. At this point, the engine speed will ramp up (RPM increase), and the DPF warning lamp will disappear. The parked regen is now in process and should take 40 minutes to complete. The cost of DPF regeneration can vary depending on whether you have it done by a dealership or perform it yourself using a professional scanner. Dealer regeneration: DPF regeneration costs between $250-$800 at a dealership, as dealerships typically charge a premium for their services. The exact cost will depend on the dealership and the type of Yeap, the VW DPF's rely on temps being raised by normal driving - they are passive. They dont initiate a 'regen' as ours do and raise the temperture via the ecu. I mate had a leon and he often had to take it for a 20 min mway drive to clear the DPF warning light. Burning that much fuel kinda defeats the point of owning a diesel. YmViFrO.
