Hi guys,
I'm planning on buying a 2002 Mk4 Golf GTI, but I had a quick question regarding a light I saw on the dash while test driving it. Sorry I don't have a picture, but hopefully someone will know what I'm talking about.
There was an icon that lit up underneath the tacho that looked like a mini tacho itself. I have no idea if this is a warning light or just something standard. Does anyone know what this means?
Even better can someone provide a link to a picture of a normal dash and what all the lights mean?

The car was in good condition and regularly serviced by VW, so I think it should be ok, but I just wanted to make sure.

Thanks
