There are many DTC's that will not cause any perceived difference. The front Llamba sensor/ sensor heater failure DTC's (A/F sensor ) being a few.(it does reduce the mpg tho' over time)

You not got a friend that has a reader or a kkl cable? Either will work to show you the codes
What's an mot failure? Low compression? They can't tell that and they don't test compression either. If your talking eml, depends on the year afair

there are a few different apps ,, they all do similar things,,, read fault codes and they also can show you loads of gauges ,,, so you can either use it like I do just as fault code tool ,,,, or you can set it up to show you your gauges on a display like a ipad or hooked up to your stereo screen
very clever bits of kit really and can save quite a few quid reading fault codes as we all know how much garages charge for this simple process
