The blog this week is based around the symptoms that indicate that your Volvo or Toyota may have a faulty or blocked DPF. Pretending that this issue will go away if you ignore it will not happen folks. You must get your Volvo or Toyota to your local independent garage for inspection straight away. Catching the issue early will save a ton of money and time.  Read on to find out more:

1.     Engine Management Light 

The first sign that your DPF isn't working properly is when the engine management light comes on, on the dashboard. The temperature and pressure before and after the DPF filter are measured by sensors inside the diesel particulate filter. If the check engine light appears on your dashboard, take your Volvo or Toyota to your local independent garage so they can investigate the fault code and further advise. Do not ignore this warning light - it is there to warn you of an issue so will not go away!

2.     Reduced Engine Performance 

The exhaust system is severely impacted when your DPF is blocked. The engine in your Volvo or Toyota will become sluggish and you will not be unable to accelerate properly as new fuel can only be injected into the engine at a reduced pace as exhaust gas accumulation increases. In addition, the engine will require more power to expel the extra gases.

3.     Unusual Smells 

When exhaust gases build up inside the engine, an unpleasant scent may be produced which can also be hazardous.  A fire could start since exhaust gases can be flammable and dangerous to breathe. Open your windows when driving your Volvo or Toyota to your local independent garage for investigation.

4.     Poor Fuel Efficiency

You will use more fuel than usual since the engine is not operating efficiently. 

5.     Starting issues 

It will get more challenging to start the engine of your Volvo or Toyota until it won’t start at all. If you have left it this long before seeking the expertise of your local independent garage you could end up without the use of a car and towing fees to get your car to the garage! Don’t ignore the warning light like we said in point 1!!!!  

6.     Damaged Turbo 

Damage to the turbocharger may also happen because temperatures can quickly increase when the gas flow is impeded or slowed down. All because you ignored your engine warning light right at the beginning! All this will do is end up costing you more and more money. Don’t stick your head in the sand and ignore this issue. A DPF filter needs to re generate - this is done often when the car is travelling at speed down the motorway - if you are driving around town on short journeys this is not going to happen and the DPF will become blocked - make sure that you allow your car to regenerate on a regular basis and then you will have no issues with a blocked DPF Filter. Happy Safe Motoring Folks!
