Actually i think you need to get your facts right the RAC and as far as i am aware the AA do carry lap tops not poor quality at all, We can access the data on most cars
Strange then how I spend a lot of my time going to garages where the 2 mentioned recovery services have taken cars which they have been unable to diagnose with their 'laptops' then. Frequently, the garage owners ask me to 'plug in' because the report from you says something like the cat is suspect when in fact its the EGR valve. Or 'coil number 2' on 3 cylinder VWs, Seats etc when its a burnt out valve or a slipped timing chain. When you take a car back to a customer's house, they will often say the patrol man couldn't plug his computer in, or he couldn't get his computer to communicate or he didn't have the right software.
This presents us with another problem. The customer believes that what is written on their report is the truth, the whole truth and nothing but the truth because you are who you are. You are held in high regard by the vast majority, I find. When we tell them its not what the patrol thought, some get quite angry and call us in to question. In order to convince some, I have had to say that if the part I fit does not cure the fault, then it will be fitted for free.
I can understand your annoyance at people posting comments that seem to call into question your company's abilities, but this is a forum and this will always happen.
I really don't think you help yourselves on here though. There must be hundreds of patrols with experience of all sorts of breakdowns yet none of you come on here and post responses in the Technical section. When I first came here, there were a couple such as Merseypatrol and Haggisathome but they too seem to have gone. Currently, MrDanno, Rolebama (ex AA), myself and a couple of others are the only ones to try and answer technical questions.
When I asked the question a long time ago as to why the patrols didn't respond, it was because they weren't held in any better esteem for it, there was no reward as such and so why bother. That was from an RAC patrol. As you say, there are good and bad in every job and it is a fact that the few bad will seem to get more attention than the majority good.
You may not believe it but I am on your side ;)
