One of my height sensors is failing, so I've just bought the Gap IIDTool, and have to say, I'm very impressed. Not just with the functionality, but also with the manual, which gives good clear instructions, particularly if something goes wrong. Things like a really good manual, make a big difference.

Just updated the instrument pack to give me the clock on the dash

I highly recommend it.

The customer service is first rate too. I emailed them with an issue one evening and had a reply in minutes. The company are active on here too.  2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Is that a "real" manual, or a download or CD disc type supplied?
I hate not getting a "proper" manual with purchases, for many things I refuse to purchase them without a manual!
I never got a manual with my IID BT Diagnostic tool, which I found a great pain and extremely annoying. I don't mind even paying extra for one to be supplied with things like this, that really need a printed one. Rant over.  John
