View Full Version : sprinter 2.2 cdi dpf off issue

Hi guys,
did anyone come across the issue on sprinter after DPF removal where a faltcode 'low air mass flow too small'?

The van seems fine for about week or two of driving, then eng management light comes on. No limp mode though. Usually only the low dpf air flow fault comes up, but every now and then intermittent fault of cat temp sensor kicks in.

Looking at the SD definitions of possible causes of the air flow problem is the temp sensor failure.. which would make sense.. but the sensor seems in good order.. at least by what can be seen on live data. I had my tuner look into this a couple of times, but no file seems to make the problem go away. Anyone with any ideas as to whether it s to do with a fault on the car or incorrect dpf removal?

many thanks
