Petrol, oven cleaner and paint thinner are some of the ways fleet managers, garage owners and diesel vehicle owners attempted to resolve blocked diesel particulate filters (DPF) during 2015, according to DPF Clean Team.
The automotive reconditioning specialist analysed the call history for its blocked DPF helpline for last year to find some of the most bizarre methods customers have used to try and unblock their DPFs, catalytic converters and silencer units.
Other failed attempts at unblocking DPFs included jet washing the filter, setting fire to the unit and even pouring oven cleaner down the DPF.
Such practices are only serving to further damage DPFs, making regeneration impossible, and significantly harming the interior of the filter.
Cameron Bryce, director at DPF Clean Team,said: “Once a DPF warning light appears on your dashboard, the worst thing you can do is pour any kind of treatment into the filter.
"Substances such as drain cleaner can remove the interior coating of the filter, stopping future regenerations from working effectively.
"The result in many of these cases is that the customer has required a complete DPF replacement, which has been more expensive that a professional clean.”
DPF Clean Team is encouraging diesel vehicle owners to seek professional advice as soon as their DPF, catalytic converter or silencer unit becomes blocked, and consider having a professional clean.
