Motorhome Remap After DPF Issues

Motorhome Remap after DPF Issues

After slowly making its way to the workshop, this motorhome was in need of some diagnostics after going into limp mode. After plugging the motorhome into the diagnostic machine it came up with fault codes that we see when a vehicle has dpf issues. So this was the first place that we would look.

The dpf on this 2012 Fiat Ducato 42 Multijet motorhome was quite accessible underneath, so we removed it see how the motorhome ran. We started up the engine and took it out for a short test drive, it drove perfectly, confirming our diagnosis.

Now we knew for sure that the dpf was the issue we cut open the casing of the dpf and this is what we found…

The dpf had become so hot when trying to regenerate the actual filter had imploded completely blocking it up. As you can see in the picture below nothing could move through the filter and this was what had caused the motorhome to go into limp mode.

With the dpf removed and the casing fitted back into place we began the task of reprogramming the ecu with the dpf software and then a remap. The motorhome remap taking it to around 180bhp.

Do you own a motorhome that is having dpf issues or simply would like more pulling power?

Coil Springs – The potholes arch-nemesis!

Coil Springs

Coil springs are an important part of your car’s suspension system, being the first line of defence when it comes to absorbing shocks and bumps from the road. Even on a perfectly level road a car would judder and vibrate as it moved, and the car springs are what give you a smooth ride, but through accidental damage or wear and tear their performance can diminish and create a ride which is too firm or bouncy.

 

An all to familiar sight and one of the main contributor’s to wear and tear on your car’s coil springs and the reason this spring broke.

After driving through a pothole the customer heard a twang coming from the front passenger side of his car. Fearing the worse he brought his car down to the workshop where we found this…

The spring had snapped 🙁 luckily it hadn’t caused any other damage and it had got him to the workshop. We ordered a new pair and had them fitted in the same day. If the owner hadn’t have heard the spring snap we could have been looking at replacing the suspension strut.

Good practice when replacing a broken spring is to replace both sides, fitting a pair. By not fitting a pair problems can occur, such as an uneven ride height, increased tyre wear and steering and handling can be affected.

Spark Plug – When Did You Last Change Yours?

Spark Plug

A spark plug, is a contraption for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine.

A spark plug has a metal threaded shell which is electrically isolated from a central electrode by a porcelain insulator. The central electrode, which sometimes contains a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The metal shell is screwed into the engine’s cylinder head, making it electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the side, earth, or ground electrode. This can be seen in the diagram below.

 

 

The spark plug works by igniting the air/fuel mixture. Electrical energy is transmitted through the spark plug, jumping the gap in the plugs firing end if the voltage supplied to the plug is high enough. This electrical spark ignites the fuel/air mixture in the combustion chamber.

History of the Spark Plug

It was first credited to Etienne Lenoir in 1860 when he used an electric spark plug in his gas engine. Early patents for spark plugs included those by Nikola Tesla, Frederick Richard Simms and Robert Bosch. But only the invention of the first commercially viable high-voltage spark plug as part of a magneto-based ignition system by Robert Bosch’s engineer Gottlob Honold in 1902 made possible the development of the spark-ignition engine.

 

So When Was The Last Time You Changed Your Spark Plug?

Spark plugs are similar to motor oil, fuel filters, and air filters in that they require routine service and maintenance to keep your engine running strong. Common signs of faulty spark plugs include slow acceleration, loss of power, poor fuel economy, engine misfires, and difficulty starting the car. Without a spark, there would be no way for fuel to ignite in the combustion chamber.
