GM Diagnostic Services for Edinburgh

Slaters Garage technicians use electronic computerised diagnostic tools to identify the source of problems on your GM that run from computer inputs. The reason for this is it keeps your cost down as we can quickly pinpoint the problem area of the GM and get straight to work on it. As a general rule we charge for the diagnostic however if we were then appointed to repair your GM after discovering the fault this charge is waived meaning your full diagnostic is completely free.

GM Gearbox Transmission & ECU Specialists in Edinburgh | GM DSG Edinburgh | GM DSG Repair Edinburgh  | GM ECU Repair Edinburgh | GM Gearbox Parts Edinburgh | GM Gearbox Edinburgh Once we have tested the GM, found the fault and repaired the problem we then re-test the GM through our diagnostic systems to make sure the fault is completely rectified before resetting any warning or hazard lights which may have appeared. This may sound common sense however some garages even charge an additional cost for this service. We think it should all be included in the diagnostic.


Most people know a computer controls a large part of your GM however did you know the ECU otherwise known as the Engine Control Unit is the most powerful computer on board. The ECU uses closed-loop control, a control scheme that monitors outputs of a system to control the inputs to a system. Quite technical we know but ultimately this controls the emissions and fuel economy of your GM to name but a few along with many other operating features. Gathering data from dozens of different sensors throughout the GM, the ECU knows everything from the coolant temperature to the amount of oxygen in the exhaust hence the ability to give the GM an immediate reading of how it is performing and adapt according to different situations.

With this information collected from various parts of your GM it performs millions of calculations each second. This allows the ECU to speak to the GM to establish the best spark timing and determine how long the fuel injector is open, ultimately determining the fuel consumption. Clever bit of kit really! Thats why its vital when doing any work on your GM’s computerised systems i.e. ECU it comes to the professionals who know how everything should read. This is where Slaters Garage stand out from most local garages. One of the biggest cores to our business is diagnostic and ECU repairs for all models of GM.
