Look, I realise this is a length-of-piece-of-string question, but I have to try before spending a fortune at the garage...
So yesterday I was driving along, and got a message about servicing the car soon. A little while later, it went into Limp Mode - so almost zero power, couldn't get it over about 30mph. No more messages, warning lights on the dash etc.
Got where I was going, and headed back home about an hour later, during which the car went normally. Fine today as well.
I only have a crappy little scanner (was fine for the ancient Rover 75 I had before), but it recorded the following codes. I've added descriptions of the codes from various websites, but they seem to vary a lot from site to site...
Yesterday:
P223B – O2 sensor?
B2013 – ???
P0000 – powertrain, but could be anything. Article above says ambient air temperature sensor?
P0007 – Fuel Shutoff Valve A Ctrl Circ Hi?
U2802 – Engine Oil Temperature Sensor. Or glow plug??
C0700 – PROBABLY MAF sensor?
Today:
P220E – NOx Sensor Heater Control Circuit Range/Performance, Bank 1 Sensor 1?
U0800 – Fuel Rail Pressure Sensor Circuit. Possibly?
P0000 – powertrain, but could be anything. Article above says ambient air temperature sensor?
P0007 – Fuel Shutoff Valve A Ctrl Circ Hi?
U2802 – Engine Oil Temperature Sensor. Or glow plug??
C0700 – PROBABLY MAF sensor?
So I'm not asking for a comprehensive description of these codes - I realise that's impossible on a forum.
But... I wonder if the car might have something more fundamental wrong with it, like a dodgy earth somewhere? Since I've had it (about 18 months now, but only covered about 12,000 miles in that time) it's occasionally done random electrical things, like the Infotainment system changing from DAB to FM, or radio to navigation, or the little LCD display between the clocks changing from Info to Audio, etc etc.
What do you reckon? I've seen suggestions about disconnecting the battery for ½ an hour... worth doing? What settings will I lose if I do this?
