A few weeks ago I fitted a tuning box (from Race Chip). At first I had a few problems because the tuning box was set too high, and it was throwing the engine light on and going into limp mode. Id turn the box down and a mate wouod plug it in and clear the code. (The code was fuel rail pressure too low). Its been fine on its current setting for a week, and now the same thing has happened when pulling away (quite enthusiastically i may add). However, I am a long way from home and I am unable to plug it in to clear the code.. Does anyone know if disconnecting the battery for a period of time will reset the ecu? Any help is greatly appreciated!

It came out of limp mode when I connected the battery back up and the engine light switched off after a few miles... I've turned the box down a couple of settings so I'll see how I go...
Thinking about a DPF delete pipe and getting it mapped out. It only seems to go into limp when the DPF starts a regen..

If you get rid of the dpf make sure it still looks like its in place, as its now part of the mot as a visual check.
If its missing and it's supposed to have one its an automatic fail

Usually they just remove the inner core of DPF so you can't detect on a visual inspection..
In my case, i'm gonna make a new downpipe without DPF because it's easy for me to get the green paper every annual inspection..

The error I was getting was 'Fuel Rail Pressure Too Low' (I can't remember the code!) I'm guessing i was getting that because when the DPF does a regen the pressure should go up, but the tuning box was already producing such high pressure? Correct me if I'm wrong..
I've never taken a DPF apart but I guess you dismantle it and remove the insides? Whereas a cat you would smash the insides out with a bar..
