Default Re: P2002 particulate filter efficiency below threshold

A follow-up to my previous post. I recently travelled to Taranaki and back from Auckland. Passing opportunities in parts of the road are limited, and in places you need a car with good acceleration to overtake safely.

The MB sometimes felt a little breathless at higher revs and I have always been careful to allow plenty of room when overtaking. But now it pulls hard until the upshift and I found myself going faster than expected after passing long trucks.

Fuel consumption has improved slightly also. The average after about 1,000 km was 6.1 l/100 km, which is better than I expected for the mix of driving during the trip.

I really should repair the differential pressure gauge as it's not good to have the check engine light stay on. But it isn't often an engine runs better after developing a fault!
