To all the hive mind. I have a merc sprinter w906 2.2 ,150BHP. I have had issues with my DPF not doing any regens , even forced ones didnt clear it. I have had 3 DPF’s in 6 years. After about 5,000 miles it starts smoking and the warning light comes on and enters limp mode. I’m usually away on holiday and i nurse the vehicle home. I tried physically cleaning the DPF with fluids and foam blowing out the back but nothing worked. The latest episode happened whilst in Paris at the olympics last summer. I nursed it home and fitted another new DPF. I got a friend to modify my ECU with “new DPF’. Ongoing i wasn’t happy with it smoking so much and although i had no engine light on i felt it was going wrong again. It was definitely not pulling and accelerating as fast as it should. It felt like half limp mode. So this time i hollowed it out and took my ecu to a garage for a DPF delete.
It’s all fitted back in and i took it for a test drive. It’s got the same issues as i recently experienced with slow acceleration and no real power. It’s as if the turbo is not working. It’s the twin turbo 2.2 engine. Could it be the turbo has failed from ‘back pressure’? There’s no leaks of oil around it. I can’t hear it whizz up when throttling. How do i check this? Nothing has shown up on my icarsoft reader. I don’t know what to do/ check next. Any help greatly appreciated. Thanks .
