Welcome to the Gary Smurthwaite website.

I am an experienced Vehicle Technician, based in Hartlepool, specialising in Vehicle Diagnostics, Remaps and Servicing. We specialise in VW, Audi, Seat and Skoda using the ODIS software.

So if you need dealer diagnostics for VW group of vehicles, go no further. Using ODIS diagnostics gives me the full dealer capability for flash programming and any security related programming like component replacement of immobiliser control units and key programming. For information on Component Protection removal, call me.

If your vehicle has a On-line digital service record like VW, Seat, Skoda, Audi, Mercedes and many more, look no further than us for keeping your service record up to date. Call for details to discuss this service.

No need now to go to the dealer!

NEW SERVICE AVAILABLE - EGR limp mode fix on VAG cars, saving on expensive new EGR valve replacement. Call me for details.

We can now offer Mercedes Benz Servicing and Diagnostics at competitive prices, call me for details.

Software updates available for most makes, ask for details, including Immobiliser repair on Corsa D, a common failure.

To see how we could save you cash

In my diagnostic work I use some of the of the most up-to-date equipment.

This includes 'dealer level' diagnostic tools for:

  • Audi
  • Bentley
  • Chevrolet
  • Citroen and Peugeot
  • Daewoo
  • Fiat and Alfa Romeo
  • Ford
  • GM
  • Honda
  • Hummer
  • Hyundai
  • Isuzu
  • Jaguar
  • Kia
  • Lamborghini
  • LandRover
  • Mazda
  • Mercedes
  • Renault
  • Seat
  • Skoda
  • Smart
  • Toyota
  • Vauxhall
  • Volkswagen
  • Volvo

Other tools we use in our work is the Diagnostic Smoke Machine, used for detecting an array of faults in intake systems, exhaust systems, fuel systems, oil leak detection and much more. This enables me to correctly diagnose fuel trim faults (on engines that runs too rich or weak) which many other garages fail to detect. We can also detect Turbo Boost leaks using the Smoke machine or by using Nitrogen by pressurising the boost system. We use an Oscilloscope for testing components and wiring on Engine Management systems which allows us to take the guess work out of the diagnosis. It is probably one of the MOST important diagnostic tools we use, a tool that most other workshops lack!

Airconditioning service

Air Conditioning service should also be carried out even in cold climate, keeping the Bactria from forming causing bad adours. Call to discuss this service. Please beware of a 4 fold price increase for refrigerant gas. Therefore I need now to charge for the refrigerant I use were as before I included it in the £50 service. So now if for example I use 500g of refrigerant I need to charge approx £20 over and above the aircon service, totalling £70. Please read the following to understand.

" Regulation (EU) No 517/2014 includes a phase-down of hydrofluorocarbons (HFCs), such as air conditioning refrigerants, with R134a being one of them. So since 1 January 2015 a quota system has been introduced which limits the amount of refrigerant that producers and importers can distribute. Therefore R134a is in short supply and just like everything in life, if it’s in short supply the price increases and at the moment is being sold for around £400 per 12 kg bottle."

Gary Smurthwaite has achieved the IMIAL Level 3 Award in Automotive Refrigerant Handling, a Legal requirement for the safe handling of Greenhouse Gases.

An alternative to superchips

With the ever increasing cost of motoring these days, I am sure, like millions of others, you are looking for ways to cut costs, and save money. One of the ways you could save money is by having one of our Bespoke Remaps. If you could get more miles per gallon and increase the performance of your vehicle at the same time, wouldn't you be interested?

However I must stress that by having one of our Bespoke Remaps carried out, we cannot guarantee you will get improvement on your MPG. Our Bespoke Remaps are tailored mainly simply for extra Power BHP & Tourque. So please be aware before purchasing one of our Bespoke Remaps. For more information about this, please see the Remaps page.


What is the procedure for a Bespoke Remap?

We remap vehicles using the car's diagnostic socket. This process is also known as chip tuning. The benefits of having your car chip tuned, apart from transforming the cars performance and drivability, is that, in many cases, it can improve fuel economy. For example a VW Transporter 2.5 TDi improved fuel economy by 20% after the chip tune/remap.

What's the cost?

See our Prices and Services page for full details.

How do I find the make and model of my car?

Select the make of your car in the drop down Vehicle List in the right hand column.

I am now able to carry out engine ECU cloning on many ECU types. This allows me to programme a used ECU from another car to allow it to work with the original car. This is a cheaper alternative to a new ECU that needs coding and programming to the original car. Please contact us for details. For security reasons proof of ownership will be required for this service.


This is an ECU being tuned that has anti-tuning software installed - not a problem for us at all!
