Can't find exactly which one but check all the fuses in box next to the battery. There should be a pair of plastic tweezers to help you pull them out.

It looks like the one marked EF12. Thanks very much. I could have pulled all the fuses out and checked them but I guess someone here would know. Ill have a look when I get home.  :-) :-) :-)

The engine light came back on shortly after replacing the fuse and according to the reader all the O2 sensors have failed again. Would this suggest a fault with the EVAP?

Has the fuse blown again?

Have you checked all the other fuses just in case the previous one was a red herring?

I would suggest pulling the ECU fuse, leaving it out for 30 minutes and then putting it back. That will reset your ecu and clear all faults.

Unplugged the battery for an hour. Driven the '2 for 8 miles and the light is off so fingers crossed  :-) :-) :-)

I'm hoping it was just flagging up a pending code. If that doesn't work then we may need more experienced help. Fingers crossed   s:D :D s:D

What are your list of codes?

If it is just 443 then you either have a wire broken to the VSV for EVAP unit or it is the unit itself.

I have the EVAP unit but it is not connected to anything except the ECU. When a wire broke to the unit, I got 443. I fixed the wire and it was fine.

I've send you a pdf that explains p0443 and what the VSV for EVAP does.

PM me your email address.

Originally I had 3 codes for the O2 sensors. I changed them all out , reset ECU and got the 443 code. Replaced the fuse. Drove it for 15 minutes no code. When I restarted it from cold the engine light can on. The 3 O2 sensors where flagged again. They are the codes that I have currently but I have replaced all 3 sensors so it can't be that. That's where I am at the moment.  s:-( :-( s:-(  im not sure how the EVAP sensors fit in or work the O2 sensors. Anyway I will PM you.

Sounds like an earthing problem to affect so much at the same time.
