I sometimes find I'm re-reading posts, over and over, trying to put the punctuation in myself, to make sense of it. Some posts are just like one long sentence. It would seem that a lot of posts are rushed, probably because of a busy workshop, but that extra few minutes of reviewing your post beforehand makes life easier for those reading them.
Quite a few posts have very little detail of vehicle spec and the work or tests that have been carried out already and then others post with a good list of what they have checked, with values they have seen etc, but then 'apologise for the long post'.
I don't mind reading a long post as I find I can do the job in my head almost. I would be thinking of my way of going about checking a system out and then see if the writer of the help request has done such. If not, another test can be suggested to them.
If they have carried out a test that has been mentioned, I often see replies of 'I already did that when it came in' etc. If this had been stated in the original post then the help replies would probably be of more use as less would be suggesting to try things that the person with the vehicle has already done.
This isn't aimed at any individuals, and I'm far from perfect myself, but some posts on here aren't far from those you see on owners club forums for complete amateurs.

Maybe if there was a slightly different layout for how you had to complete your original help request, such as the diag equipment used one, fault codes could be listed just under the make and model with engine size and code box.
One other annoying thing is when lots of help has been given and then the post dies off. Surely those cars can't still be hanging around in the workshop. What eventually fixed it?

I do read through all the posts when I have time and I do remember bits of info that have then helped when I have similar problems come into my place. Just one of those bits of info that saves me time on one job easily covers the cost to be a member of UKAT.
If it's a brain tease then I'll have a look in the archives to see if there's additional info of a known issue with a vehicle but then I've also have a good look at the systems, wiring diagrams and pinouts, expected values etc before I even open the bonnet on a lot of jobs so I'm prepared for diagnosing that vehicle. A lot of people don't seem to have the basic technical information a workshop dealing with modern vehicles needs.

Hope we can see an improvement in the posts and I see where the guys that have spent years in the diagnostic game are coming from with not just handing out the silver bullet. I don't think it's unreasonable to get the original poster to do some more suggested tests because that way they should also be educating themselves along the way.
I admit that I haven't been on many training courses but I do spend hours and hours reading up on new systems and teaching myself. I'm always learning something new each day and luckily I have a fairly good ability to retain that knowledge. If you don't have time to spend hours investigating the faults then maybe you should just sub out all of your diagnostic work and carry on with the service and brake pad work. It may be more profitable for you anyway.

Not sorry for the long post,

Liam
