Definitely worth having if you intend to do any maintenance on your Mk1. Its not really a book, more of a spiral bound "report", but contains all the info you need plus the LED and wire to read the codes.
Using this I was able to diagnose an intermittent idle issue to a broken £10 thermoswitch, rather than having to guess and start replacing things like HT leads and coil packs.
Your car may be running at less than optimum settings if fault codes have been activated, and this is an easy way to check and investigate further. Highly recommended.
