Why do garages charge seperately for a diagnostic check

[Bassrock]

Hi all,

So your garage or mechanic has a diagnostic reader.

OK there are many types, from a simple code reader at £50 is to your full blown Bosch KTS dip phil bar and scar at circa 6.5 - 7.5K and all the sundry charges per annum built in (of course), or if your really rich try snap-on verus etc...

So mechanic says he will do a diagnostic you get charged anywhere between 40-100 squid say, OK so your business has to recoup the test equipment cost.

So why is this not built into the hourly charged rate.

Any service on any car should always have a diagnostic quick check run on it, how else can you deem it to be fully serviceable !, therefore costs should be spread across the hourly rate.

Any thoughts out there !
