Expert Fault Finding With Symptom Driven Diagnostics (SDD)

With today's advanced vehicle technology, cars utilise an extensive amount of computerised technology - relying heavily on the ECU (Engine Control Unit) and it is essential that workshops have the latest diagnostic equipment and the best technical expertise available if they are to provide their customers with a professional service by identifying and resolving faults effectively.



Hereford 4x4 has invested in both Autologic and the very latest Land Rover SDD (Symptom Driven Diagnostics) technology. We are able to fully interrogate a vehicle's diagnostics system and readily establish what faults are present and resolve them.


This technology takes away the guess work from fault identification, saving time and money; getting your vehicle back on the road as quickly as possible.


Our technicians are fully trained in the use of this technology and their skills are maintained and updated on a regular basis - ensuring you of our experience and expertise at all times. Our main dealer level equipment allows our techicians access to upload and download service information (this feature is available on newer Land Rover models).


SDD (Symptom Driven Diagnostics)  

SDD is the latest development by JLR in vehicle diagnostics. Designed to be easy to use and extremely efficient in fault finding. Conventional diagnostic systems read fault codes and offer them to the end user. It is then up to the end user to analyse the codes and find the vehicle fault from the data that has been provided.

SDD instead asks the end user the fault with the vehicle and progresses to analyze the fault codes and offers the solution to fix the vehicle on a relevance to likely ratio.

Should you wish to intervene and only see the fault codes then this option is open to the end user but keep in mind, SDD was developed to recommend the repairs.

Alongside diagnostics the service functions allows vehicle and module programming and vehicle customisation.
