🚐 Mercedes Vito Taxi/ Private hire in for our DPF Cleaning Service
This Mercedes Vito came into us with a blocked DPF system, with the filters heavily restricted by a combination of ash and soot.
Rather than relying on chemical cleaners or trying to force a regeneration, we remove the DPF and clean it on the bench using our water-pressure pulsing process.
Over the last 8+ years, this process has given us great success in recovering heavily blocked DPF systems, while also allowing us to properly inspect the filter and investigate the root cause of why it became blocked in the first place.
But this one was a little different… 🤔
During the inspection, we found part of a hacksaw blade inside the DPF! 😳
Further investigation suggested the vehicle had previously had a DPF delete carried out, which apparently hadn't gone to plan or had subsequently failed its MOT/taxi emissions testing.
It looks like the vehicle was then reverted back to the original emissions system — but unfortunately, the evidence of its previous life was still sitting inside the DPF!
Once again, this highlights why we don't simply clean a DPF and send the vehicle on its way.
Understanding why the DPF became blocked in the first place is just as important as cleaning it. Our process allows us to inspect the system properly, recover the filter where possible, and help identify any underlying issues that could cause the problem to return.
