Novice error!

[jonesi7]

Hi,

Can anyone help? I had to removed my instrument cluster to rid myself of a spiders web. In my haste I didn't disconnect the battery and now the speedometer dial is about 10-12mph out so I am having to drive using the digital readout instead which I have verified by using GPS on my phone.

Does anyone know how to reset this without going to the main dealers?

Thanks
