thinking of buying one of these would just like to know what they are like and are they a multifit as i already have a vw fault code reader but had a look at one on ebay and made think of getting one as i like my gadgets so the other half says
Agree with Elliott, try the liquid guage from Awesome GTi
Liquid gauge seems the best bit of kit for this kind of stuff.
IF they find somewhere proper to mount it, imo
You could put it anywhere you want aslong as you have the skill to make it fit
