Code reader advice
Q: In the past you have recommended the Foxwell range of code readers and I plan to buy one based on this. I’m only a keen amateur so don’t need the full bells-and-whistles type, so it’s a choice between the NT201 and NT301. I can see no difference between their respective specs apart from the latter having a slightly larger screen. Is this the only difference? Or is there more that I haven’t been able to suss out?

A: The basic functions of the two Foxwell code readers are quite similar, however the NT301 has a few functions which the NT201 does not. The NT301 has more control keys and allows the codes to be scrolled back and forth, as opposed to the NT201 which can simply go back to the previous screen. The display on the NT301 is not only larger, but also superior in regard to quality. The machine itself is also heavier and more solid in its feel.
In terms of operation, the NT201 carries out seven generic OBD system tests, while the NT301 carries out nine, the extra two being ‘Modules Present’ and ‘Component Test’. The NT301 also has a longer menu, covering DTC look-up, review and the ability to print data via a compatible device.
Both machines can read and erase data, and also display live data and render it in a graph form. However, the NT301 can also record data, allowing you to take a test-drive and then look back on the data stored during the journey; this can be helpful to diagnose more elusive problems. It also has an 02 monitor test.
Although the NT301 is the more costly machine, I believe that the extra features do justify the additional expense.
