What is VauxCheck?

VauxCheck is a software package that will help you read fault information from your Vauxhall or Opel car engine.

The package is designed for use with most Vauxhall or Opel cars from 1997 to 2008 (both petrol and diesel models).

What can I do with VauxCheck?

VauxCheck will read and display the fault codes from the on-board computer (ECU) that controls your car engine.

If your car's Check Engine light is on, you can use a diagnostic tool, such as VauxCheck, to read the fault code that has caused the light.

You can also clear the codes (reset the ECU). This will switch the Check Engine light off.

Why would I need VauxCheck?

If there is a fault within your engine or exhaust/emissions system, e.g. misfires, poor idling, stalling, the engine control unit (ECU) will normally record the problem in the form of a fault code.

Depending on the severity of the code, and the number of times the engine has seen the fault, it will often then switch the Check Engine light on on your dashboard.

This light is designed to alert you to a fault, e.g. an engine sensor reading out of range, high exhaust emissions, wiring fault etc., that may be affecting your engine running, and hence affecting your car's emissions.

If the light is flashing, this indicates a more-serious fault that might be damaging your catalytic converter. In this instance, the car should not be driven until the fault has been investigated and repaired.

If the light is on, you'll need a tool such as VauxCheck to read the fault code from the car. This will point you in the direction of the fault. Even if you aren't comfortable tackling the fault yourself, you'll be armed with some valuable information when visiting your mechanic.

What do I need to use VauxCheck?

You'll need a PC or laptop (running Windows 98SE or newer) and an ELM327-based car diagnostics interface. The interface provides the connection from your PC to your car.

We sell the ELM327 interfaces - separately, or with the VauxCheck software.

Can I remap my ECU, adjust mileage, or reset other lights (ABS, service, airbag etc.)?

The package is currently designed primarily for engine fault diagnostics, so cannot modify settings on the car.

It does now cover fault code reading for certain ABS, transmission and immobiliser systems (see coverage information for more details). We are looking at expanding the package to cover other systems.

Can using the software harm my car?

No. The software uses industry-standard queries for engine diagnostics. The package is primarily only asking the on-board computer for information, so it cannot affect running of the car.

What if it doesn't work with my car?

We try to be realistic on this - there are so many different car and engine combinations out there, there will always be a small number of cars it won't connect to straight away. We hope you appreciate our honesty on this and will work with us.

If you have a car that it doesn't seem to be working with, we can gather 'logging' information from the software. Using this, we can work out where the problem is and fix it.

What about updates?

This is a developing package - we're hoping to add many more features. Updates will be free for VauxCheck customers.

I bought a lead from [ebay], will VauxCheck work with it?

Good question. Provided the lead is a correct implementation of an ELM327 chipset, then it should be fine. Please email us before ordering the software to confirm compatibility.
