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).

coverage/compatibility list.
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.
