Looking to buy a DPF cleaner?

Cleaning DPFs is becoming another timely job for the workshop

Published:  28 July, 2014



Euro 5 emission regulations required vehicle manufacturers to begin fitting Diesel particulate filters (DPFs) to their vehicles in order to reduce the number of harmful pollutants coming from the tailpipe. While these do their job well, the regeneration of them, where heat is able to burn away soot and dirt particles making it useful again, requires a specific set of requirements. Driving a car around town is no longer enough to clean the DPF so a new idea is needed.

The Liqui Moly kit is supplied in two parts. The wand and hose and the pressure gun and additive are all supplied together, while more additive can be ordered as and when needs be. Our kit was supplied with a DPF cleaner and a purge, a pressurised tank spray gun hose, wand and different spray end adaptors to allow you easier access. You will need a compressed air line which attaches to the spray gun for use, as this allows the cleaner to be distributed around the DPF better.

The gun is well made, not a cheap construction but instead developed to operate at the required 4-6bar of pressure. The hose connection is flexible enough to be shaped to access tricky areas if required while the wand adaptors are thought out, again allowing access to a number of different vehicles, where reaching the DPF sensor may be easy or restricted. As well as the air hose, you will also require a funnel to pour the liquid into the spray gun as the neck is quite narrow.


Diesel vehicles doing mainly short distance trips are prone to experience DPF troubles. To regenerate, the filter needs high temperatures to burn the soot to ash. If the filter does not reach those temperatures due to short distance trips, the filter will clog up prematurely. The Liqui moly DPF cleaning kit is suited for preventative application during servicing too, thus saving the customers from running into DPF troubles.

    A job I was recently asked to look at had a bit of an odd symptom; it would run (apparently quite well), as long as the camshaft position sensor was unplugged. The previous history on the vehicle, a 2009 2.5 TDI VW Transporter, was very limited. During my initial inspection, I noticed that the vehicle was suffering from a slightly extended cranking time, which is quite normal for a cam sensor related issue, as the engine ECU cannot easily calculate which TDC is which.
