Hi guys-
I do diagnostics part time (about 3 times a week) and I have never had an incident that has been like this, need your input to find out how you all deal with it.
I had a 99 subaru legacy with a no start.. No spark, no coil control. Checked the wiring and saw that in this model there is an igniter that controls the coil. Checked the igniter and was getting the PCM square wave control on it but no output. Called a bad igniter, the car ran fine as soon as the part was replaced.
2 FREAKING DAYS LATER, customer calls me to his house with the SAME SYMPTOMS!! I check, no spark, no coil control, BUT, this time there was no square wave on the igniter. This thing had a crank sensor that failed after the igniter was replaced. Put a crank sensor in it, the car ran.
But customer now claims I made a bad call and does not want to pay for the second diag. He does not understand nerd, so trying to explain to him is futile. What do you guys do in situations like this? Do I just eat this and walk away?
Not at all, in fact no way.
A car can develop a fault at any time as you well know.
I would imagine that you have your captures and hopefully the old parts.
If he does not want to look at your evidence then it is only because he does nor want to lose the argument.
offer to put both parts back.
i finished a V10 M5 today that had a fault for the crankshaft sensor
in reality it had a faulty transmission input sensor and a clutch position sensor, both had gone faulty at the same time.
It happens
Fact is however you will never submit to working for him again and now you have what I call "power shift"
When the car did not work he needed you, now that it is fixed he is in a position of power.
No way would I let him get away with it
