Engine Diagnostics

Our approach to diagnostics is different to many others, we don’t offer just a fault code read service. This virtually never proves the part in question is actually at fault and often leads to good condition parts being replaced for no reason. For this reason we offer a Diagnostic Evaluation.
​
There are many steps involved in our evaluation process:

• First we will consult you and find out as much information as possible about how and when the fault occurs.
• We will then evaluate the car and try to replicate the fault in question.
• We will carry out a full vehicle fault code report, using the most suitable diagnosic tool for the job.
• We will spend the time checking wiring diagrams, checking for any relevant TSB (Technical Service Bulletins), and make a test plan.
• Functional tests, basic wiring checks, checking sensor signals using specialist equipment like oscilloscopes and test gauges and spending up to one hour of time on your car.
• If the fault is of a more complex nature, we will make contact to discuss what the next steps are.

The cost of this is £68 plus vat.

We have invested tens of thousands of pounds into the latest diagnostic equipment, with all systems kept up to date with expensive subscriptions to allow us to troubleshoot issues on nearly all makes and models of car and small vans.
​
We have found in recent times that sometimes the generic/aftermarket diagnostics systems just aren’t good enough to get the job done, so for our core market, we have bought the genuine manufacturers tools that allow us to communicate with your car in the correct way.
​
We currently have OEM factory diagnostic access, with direct links to these manufacturers:

• VW/Audi/Seat/Skoda
• BMW/Mini
• Mercedes Benz
• Bentley
• Porsche*
• Volvo
• Jaguar/Land Rover*

With having all the correct information and test data for your particular car, we can carry out more more in depth testing and avoid just buying parts in the hope that it might fix the problem, saving you money in the long run.
