Just an UPDATE....

I have had my car in a local electrics garage and they have looked at it, said engine, brakes etc all seem fine. They put it on the machine but loads of codes came up, they think this is because no one has wiped them from memory when previous work has been done in the past.

They advised to wipe all the codes, then drive it till the issues I have been having re-occured and then they can read what those fault codes are. I have therefore gone ahead and done this and the error code that comes up (a cheap scanner I bought off online arrived this morning) so I used that one tonight and the error code is - P0720. I believe this code stands for speed sensor circuit malfunction....let me know what you think and advice regarding this!

I am going to ring same garage again tomorrow and tell them about what I found and see what they think and hopefully take it down and get issue resolved. Not that sure thou, if this is likely to be the fault (assuming it is) and if its a simple thing to fix or not. I have looked a little online and seems the sensor is just a small thing to replace but again I personally don't know enough about these things.
