LPG Servicing
We can service and repair almost all kits on the world wide market, we have a large array of the most up-to-date software and diagnostic leads, we also specialise in factory fitted and powershift systems.
It is very important to service LPG kits as there are some contaminants in the fuel as there is in diesel and petrol which is why we have inline fuel filters. Failure to do so can cause parts to operate incorrectly, which in turn will fuel the vehicle incorrectly, or if left for sustained periods fail altogether and require replacement. We recommend the gas system be serviced at least annually, or sooner dependent on mileage.

Vauxhall Servicing
We see more Vauxhalls in our workshop for LPG servicing and repairs that all the other makes put together. For this reason it warrants spending more time on this section than all the others, after all we are trying to convince you our customer that we know what we are doing.
We see the Astra, Corsa, Vectra, Omega and Zafira range on a weekly basis, in fact if you rang Millbrook the original installer they will almost certainly direct you to us as we are one of their Main Dealers in the north of England.
We often receive calls from owners wanting to book in their Vauxhall for a diagnostic check or a service, in most cases it is because they have a running problem or it will not run on LPG, we try to explain that if they have a poor running fault or if the system keeps on switching back to petrol then the starting point is a LPG service.
Most of the ones we see for the first time have evidently been neglected from new with often no more than a filter change during its lifetime. Over the years we have found so many individual faults on this Necam system that we have put together a service schedule of our own.
Certain components are removed, stripped, cleaned and re-set as well as pressure adjustments made, finally computer checks are made using Millbrook software. Having learnt everything about these systems over the last 9 years we are obviously not going to give away our trade secrets.
If the service has not fixed the problem then we have either already identified the cause within the service of more diagnostic tests will be needed at extra cost. Having the use of the rolling road also assists us to diagnose common faults like the system back to petrol or LPG injector / metering head imbalance.
If the vehicle is booked into us and the LPG system is not even attempting to switch over to gas then although it may benefit from an LPG service, diagnosis should be carried out first. Finally after we have repaired or serviced your Necam system we are limited how long we can spend on its road test, up to 10 miles is quite the normal. The reason we mention this is because we sometimes hear of intermittent faults reported by customers where once a week or every 1000 miles or so the system cuts our or switches back to petrol. It is not uncommon for a customer to buy a Vauxhall and bring it to us not running on LPG and then to find when we have fixed it that a secondary intermittent fault is present.
It does not matter to us what the fault is as we will always fix it.
But remember
Service first and then further repairs and diagnosis if necessary at an extra cost

Ford Systems
Ford Motor Company also have vehicles on offer with a factory fitted option. The kit fitted can be one of three, the most popular one is the metering head variant of the Necam / Koltec system and this is the same system as the one fitted to the Vauxhall vehicles.
The other two systems are liquid injection systems. Liquid injection systems works similarly to a petrol-injection system, liquefied fuel is pumped out of the tank to a fuel pressure regulator and to the injectors. The system comprises of an LPG fuel tank with an integrated pump, a fuel pressure regulator with a pressure sensor and safety valve incorporated into it, liquid gas injectors and the LPG ECU
The Icon / Metatron system is a standard Multipoint system where as the Vialle system is a fully sequential system, apart from this the kits operate in the same way, for more information on how they work please visit the 'talking technical' section of the 'LPG Conversion' page.
These systems require less time to service and rarely suffer from a build up of contamination, but theses systems do develop faults that we are equipped to deal with, using the wiring schematics of the system, and having a full understanding on how these systems work we can diagnose and repair them.
Of the two systems we see more Icon / Metatron systems than we see of the Vialle type, unfortunately the Icon pumps have a reputation to suffer from failure, fortunately we have acquired a number of replacement pumps in which we can remove and install a brand new pump, the Vialle pump has been designed with an internal lubricating system and varies its running speed dependant of the gas demand, these wear reducing technologies reduce the number of pump failures we see with the Vialle system.
