Hi everyone, I need your advice.
First off, I'm in Switzerland where emissions regs may be stricter (not sure).
Car = 2012 Skoda Octavia 4x4 1.6 TDi (common rail engine).
My car failed its inspection (called MFK here) because of emissions too high.
The rules are;
At idle, the particles per cm3 must be less than 100,000.
At 2000 rpm, the particles per cm3 must be less than 250,000.
At the first test my car had over 5,000,000 (5 million) particles per cm3. I took it to a garage (well recommended by a friend of mine, they speak English and I trust them) and they suggested first to try cleaning the DPF with an aerosol can, and a forced re-gen. They did that (for free), but on the next re-test it failed again with the same values (5 million).
So next I had the garage install a reconditioned DPF which I got from eBay. The recon DPF looked good - when looking inside everything was clean and you could see the welds on the case where they had opened it up and replaced the internals. The seller on eBay is a DPF specialist and has 94% positive feedback from 5900 sales... so seems trustworthy. It cost $300. It came just as the DPF with a flexi pipe. The old exhaust middle pipe had to be welded on to it.
Anyway I had a garage install it, which cost $900.
Today I got the car re-tested, and it failed again. The emissions have improved:
At idle = 300,000 particles per cm3 (max is 100,000).
At 2000 rpm = 400,000 particles per cm3 (max is 250,000).
So there is a dramatic improvement from the old DPF... but the tester said the values are "really high for a new DPF". Also I used to get a hesitation at < 2000 rpm in 4th gear when going up a slight hill. That is fixed now, so that's also an improvement.
So what do you think? Have I bought a defective DPF, or could there be something else wrong with the engine?
I'm $1200 into this so far... the car's worth about $3000 - $4000.
What should I do? Thanks in advance!
