Hertfordshire's Leading 4x4 Specialists

As the counties leading 4x4 specialists we are more than able to resolve all manner of problems experienced by owners or 4x4  vehicles that have so-far eluded the dealerships and independent workshops. Located in Hemel Hempstead, our customers come from St Albans, Watford, Hatfield and surrounding areas, including Essex, London, Bedfordshire and Oxfordshire and in addition we regularly have customers travel from all over the UK for our unique skills and capabilities.

Manufacturers List

We have the same diagnostic equipment as the dealerships for the following 4x4 manufacturers

  • Land Rover
  • Range Rover
  • BMW
  • Audi
  • Nissan
  • VW / Volkswagen
  • Vauxhall
  • Honda

This allows us to carry out all the tasks that can be performed by regular dealerships, however we also have additional skills and equipment that allows us to carry out repairs and modifications that the dealers would love to be able to offer. We can for example supply and fit exchange or second-hand control units, that even the manufacturers say is impossible. We even code them to the vehicle, so they work the same as a new control unit but at a fraction of the cost.

Tuning - for Performance & or Economy

We are able to remap the engine ecu on almost all models to improve power and/or economy, on Turbo Diesel models we are able to safely increase both power (HP or Horsepower) by about 30% and at the same time increase MPG by about 10%. 

On Petrol models we can also remap the ecu, on turbocharged petrol models significant increases can be achieved, the amount varies depending upon the exact model - ask us for details on your particular vehicle.


We are also fully qualified LPG installers, and are recognised all over the country as specialists in fixing the problems introduced by other so-called installers. Whatever the problem we will find and fix the reasons why an LPG system is not working correctly. Customers regularly travel the full length and breadth of the country to finally get their LPG systems working correctly. 

We also service LPG systems and provide a full certification test service for insurance purposes.

Whatever you need, advise or repairs, we are only too happy to help, give us a call or email us and we will do all that we can to help you.
