1st 4 Garage Services Car Diagnostics In Dagenham

Vehicle Diagnostics In Dagenham

We really are 1st 4 Diagnostics

Mass Air Flow, Intake Air Temperature, O2 Sensors (Lambda), Knock Sensor, Fuel Pressure Sensor, Throttle Position Sensor, Nox Sensor, Coolant Temperature Sensor – the list could go on, and on!  The vehicles we use are swamped with sensors and control units and, like most things, they develop faults. We have invested heavily in the latest diagnostic equipment which reads information stored in the vehicle and provides essential information to our mechanics. They in turn have the knowledge and years of experience to interpret that information and provide an efficient and cost effective repair for our customers.  Our diagnostic equipment emails the reports from our workshop to our service reception (and even to our customer if required) - which allows us to review and discuss the information with our customer.   


Dashboard warning light - 1st 4 Garage Services In Dagenham

Dashboard warning light come on?

Not all warning lights will require diagnosis work, some just warn you that something simple requires attention – like the engine oil or screen wash needs topping up – but others can indicate a fault with the vehicle and that's where 1st 4 can help.


Why choose 1st 4?

Diagnostic equipment is expensive to buy and maintain – but accurate diagnosis depends on both that investment and equally the knowledge of the technician using it. We have the technology once only available at the vehicle main dealers and can provide you with accurate information at competitive prices.
