What Does A Diesel Engine Carbon Clean Do?

Commonly known as de-sooting or intake cleaning on diesel engines, is an absolute must for all common rail diesel engines, which is basically any engine that is diesel powered built from approx. 2006 onwards.

2006 s is when the governments implemented new emissions rules governing car manufacturers. This however forced the car manufacturers to fit devices such as an EGR which is extremely damaging to a cars performance when it becomes blocked.

What Does A Diesel Engine Carbon Clean Do?

Basically, the intake air passage of the engine becomes blocked as can be seen in the pictures and this reduces the size of the opening that the air can flow through to the engine and reduces the power of the engine but worse it wears the engines internals to reduce the life of the engine.

Most workshops don’t have the specialized equipment to do diesel engine carbon cleaning and therefore when you get a service, they don’t tell you about it.

At Coastwide Service Centre we always check your intake and we have the latest state of the art diesel carbon cleaning machines to bring your car’s engine back to life with that new vehicle power, increased fuel economy and all round better performance from your engine. 

Most car owners expect that over time their vehicles engines performance will reduce as it gets older, however this is not the case with a well-maintained engine. Its bad performance is due to the intake, cylinder head and EGR system becoming clogged which restricts the air flow and therefore reduces the power, fuel economy and performance. After a full intake and EGR system clean your engine will have its performance and fuel economy back and a smile on your face. 

Signs Your Vehicle’s Engine Is Becoming Blocked Are:

  • Blowing smoke
  • Reduced power
  • Poor fuel economy
  • Rough idle
  • Turbo lag
  • Slow acceleration
  • Engine light on (when really bad)
  • Engine knocking noise (when really bad)

If you have any of these issues then get down to Coastwide Service Centre to get your diesel carbon clean performed and get that new car power smile back on your face!

    Hello mate how much does this intake carbon clean cost for a 2011 prado with 160000kms? Cheers

  • Cost for the Carbon clean is $249 in total. We have been seeing really good results and getting good customer feedback on the Prados as they seem to build up a fair bit of carbon around the EGR (exhaust gas recirculation) and also the intake valve stem

    Hi guys,

    Just wanting some info/pricing on a carbon clean for my 08 nissan pathfinder. Hoping a full carbon clean would be a good place to start, i have always had crap fuel economy on my stock pathfinder and sometimes very sluggish when cold, not just the standard turbo lag. Currently getting 12L/100km or around 17-20 around down.

    2008 pathfinder YD25 engine auto 160kms

    Gold coast based, think this would be beneficial for me? Please advise costs.


  • A full carbon intake clean is $249, we will also check your vehicle and make sure there no other underlying issues relating to the poor fuel economy while we have it in at the shop.
