Hi Chris .

Now is the time to gert the management system checked for malfunction codes, from the codes this will help us fix your problem .

Can you pop round to your local shop and have them check for codes .

Once you have ther codes post them here for me to check out for you .

Or maybe a friend has a code reader ,or you could buy one yourself for under £50
cheaper than getting this checked at the Garage.
