Forum rules
Not many rules really, this board being aimed at technical issues, it shouldn't fall foul (hopefully) of some of the more personal issues that can affect forums.

Rule 1 - Is that you need to think very carefully before posting anything technical or asking anything technical relating to the security system of the car - See 'Security Issues' sticky for more info.

Rule 2 - We (MGF Register) do not support copyright infringement and therefore references to CD ROM, PDF versions or paper copies of the workshop manual (for instance) should not be posted on the forum. We don't want to get into trouble and we'd rather sell you a genuine hard copy through our Regalia shop anyway! :)

Because advice is honestly and freely given in this technical section, much of it will be amateur experienced based, so any information is given in good faith and is not guaranteed as correct.

If the issue making the MIL come on is solved, the light should usually go out after 5 decent running circles. The fault codes are not cleared, though, they will be stored in the fault memory as “historic”. If it stays on, there might be some other problem, so a PScan session is highly recommended.

Thanks for all the help we know the fault is a miss read from the lamba sensor bank 1 but the five grand code reader we have used is unable to clear the error code.
Someone suggested disconnecting the battery and make a circuit by holding - and the + leads together thus clearing the memory sounds a bit like witchcraft to me but what can it hurt to try any thoughts.

Errm, no. And it might hurt, as you never know if any devices (aftermarket radios) have a buffer battery that could suffer.

Go for James’s offer and have the beast “PScanned”. :lol:
