Hi, I should start off saying I am new to Mercedes and Diesel cars so.... I have been looking for a while and finally found my MBZ. I have driven it around 800 miles so far with no problems. I decided to start trying biodiesel so I filled up with b20. After a day or so (50-60 miles) I started noticing it smoking a bit and I think fumes were coming into the cabin. I bought new fuel filters in anticipation of the switch but thought it would take a couple of fill ups with bio to start noticing anything. Is it possible that a clogged fuel filter is causing the smoke? I have not noticed a power loss. Anyway any experience on this matter would be greatly appreciated. Thanks in advance, Alex
