MECHANICAL PROBLEMS
 

There is a huge misconception that Carbon Cleaning is a Repair Service, That it fixes cars engine running problems, Wrong it does not do that, but what it does do is clear out Carbon Deposits that can create engine running problems, Where there is carbon build up, there are problems, Remove the Carbon and you have half a chance of aiding the engines health.

02

ELECTRICAL PROBLEMS
 

Electrical problems can be created by Carbon getting onto sensitive sensors around the engine. It has been know that a Carbon Clean “can” aid clean the sensors around the engine and in the exhaust. Please note there is no guarantee with this.

03

EGR VALVES REPAIRS
 

We are going to be upfront about this myth, Can Carbon Cleaning Unblock or Unclog an EGR Valves, The simple answer is "MAYBE" as we do a Carbon clean, The extra hot exhaust gases get recycled through the EGR Valve and "Can" get to work on the Carbon Crud that has built up in there over the life of the engine, The only way to head off EGR Valve issues is simply to have your car/van or lorry Carbon Cleaned every 10'000 miles or every 12 months before your annual oil service .

DPF FILTERS

DPF filters do get blocked, but they can regenerated by us, but this is if they have not exceeded their, regenerated limit. If we can regenerate the DPF filter for you then we simply Will at an addition cost of just £75.

 

But the question that is hardly ever asked is "WHY" is it getting blocked? The simple and direct answer is the Engines Valves are not closing 100% correctly, Making your emissions to high and the gases are rich in moist sticky un-burned fuels, which the ash from your emissions sticks to,

 

So a Regeneration will help solve the DPF problem for you, but for a short while only, you really need to fix the "WHY" 1st, Carbon Cleaning will fix the "WHY" and then you can use a DPF fuel line cleaners to flush the DPF through, We normally do carry a DPF Fuel Line Cleaner in our vans for only £20.

VNT Turbo's

05

Since the late 1990s many diesel cars have been fitted with a turbocharger using a Variable Geometry Turbine or Variable Nozzle Turbine. These turbochargers are very effective in minimising the effects of turbo lag, resulting in a more responsive throttle especially at low engine speed and much improved torque.

These systems work by changing the speed and direction of the exhaust gases onto the turbine wheel. The most common of these systems is Garrett’s VNT ® mechanism which incorporates a ring of small movable vanes around the turbine wheel. These vanes are sometimes referred to as the speed control mechanism. At low engine speed, the vanes are in the “closed” position narrowing the gap between them which effectively accelerates the exhaust gas onto the turbine wheel. At high engine speed the vanes open up slowing the exhaust gases, which prevents the turbocharger over-boosting. In most cases this level of control negates the need for a conventional wastegate.

Despite these benefits, such turbochargers can be prone to problems. The vane mechanism

is easily affected by carbon build-up, which, if it becomes excessive, can cause the mechanism to jam. This can occur quite quickly if the vehicle is used predominantly for

short journeys where the engine is not allowed to get up to full operating temperature. The mechanism may jam in either the fully open or fully closed position resulting in no boost or too much boost from the turbo. If the turbo over-boosts there is a real danger that it’s internal components will be damaged, resulting in the need for a complete replacement

unit. In many cases, the computer controlling the engine will sense a fault and will severely limit the engine’s performance in what is called a “limp-home” mode to prevent any further damage. Low boost may also cause black smoke under acceleration. The problem may clear itself by cycling the ignition switch, but it is extremely likely that the problem will recur.

Previously, the only solution was to buy a brand new replacement turbocharger, because the VNT mechanisms could only be cleaned at the factory. However, Carbon Doctor have the correct equipment to reduce the Carbon without removing the Turbo Unit itself.

EMISSION'S REPAIRS
 

The Carbon clean significantly reduces dangerus emissions and "can" also help to achieve emission MOT test levels.
