Thanks for the reply.
The exhaust was picked up for a leak on the front (of 3) box although this is not too near the lambda. While we are on the exhaust I only really get it blowing out of one pipe at the back. Could I have a blockage that is upsetting the lambdas, bearing in mind both play up and I have no discernible loss of power?
The files I am trying to up load are of a correct type and well under the 10Mb limit. The error message I get is:

There seems to be a problem on this server.
If loading does not finish properly, please stop the request and re-submit the form.
I could email them if that would help
