For the 2nd time in 6 months my Honda diesel has went into limp mode whilst towing. Never happened at any other point. Googling the code and research pinpoints carbon build up at the turbocharger/supercharger actuator - an issue linking to the DPF it seems.

We are at the point of chopping the car in as it is our main towcar. But, in most cases we'd be looking at a DPF car and who's to say we'd be buying another car with carbon build up issues!


Has anyone used these Carbon clean companies? Do they work or is it a manual strip down/clean that is needed? I read plenty of positive comments /their website but these could easily be paid endorsements.

Thanks in advance

It won't work, don't waste your money, anything they put in wouldn't get through the combustion process anyway, even if it did all it would do is contaminate the cat and DPF further, which is why most of the time it's nothing more than water anyway.

My brother's 2013 Honda Accord has the 2.2 iDTEC engine and he had DPF problems after buying it. He tried sonic cleaning etc but it never worked and he ended up getting a new DPF (expensive).

If you are handy with a spanner then what can work is to remove the DPF yourself and pressure wash it (low-mid pressure) from back to front first then the opposite. No detergents, just warm water.

My previous car was a Euro 5 diesel and the only additive that worked was Archoil AR6400-D Max. It claims to reduce the temperature required to burn off the soot and when monitoring with my gizmo it did actually work and soot build up during regular driving was very slow compared to without the additive.

Personally, I would get rid (which I think you are already looking at doing) and get away from diesel. Regens can cause oil dilution with the diesel and rob the crank of lubrication etc. A decent sized forced induction petrol should be fine for towing.

I doubt if this will help, but it's certainly a dramatic way to clean off excess carbon deposits!
