INTERMITTENT FAILURES

Does this sound familiar?

"My car misfires sometimes."
"The engine won't start at times."
"The engine surges, but only first thing in the morning."
"It runs fine until it is hot."
"It only misfires going up a really steep hill."

Intermittent failures are frustrating both for you, the vehicle owner and ourselves, the vehicle repairer.
They are also a fact of life in the modern vehicle, with multiple electronic micro-processors, sensors, actuators, kilometres of wiring and CAN data bus systems all talking to each other at the same time. Experience has taught us that the best approach is to agree on a starting price and for us to report to you on our findings as we go. As for the time it takes, once again there is unfortunately no easy answer - it will take until we have traced the fault.

Can we just plug that tool into the car?

Yes we can, however it is not that simple. After getting all the information from you about what is happening to your vehicle, we would indeed plug in our scan tool and confirm whether any stored faults have been recorded by the ECU. in some cases, the code will lead us directly to the problem or the start of the problem and we can carry out a straightforward repair. That is where you are pleased to have your car back (fast!) and we look like car magicians - an ideal scenario. But, what about the nasty problem? That only happens approximately once a week and doesn't leave a fault code to be scanned. What then? That is where the other two questions arise.

How much will it cost and how long will you need my car?

Unfortunately, unlike our first case, we will not be able to give you an estimate of time and cost. With an intermittent problem that the vehicle's on board diagnostics cannot capture, we have to capture and diagnose when the problem is occurring. So, if the problem occurs only once a day or once a week; that is the only time we have a chance to trace the fault. We will use a Labscope with recording capabilities which we can replay and we will use all our skills we have gained through experience and constant training. However, we cannot monitor all the components and wiring at once.

What does it sound like to you?

Depending on what the problem "sounds' like, we will embark on a logical diagnosing process until we can trace the fault.
As your repairer, we should make you aware of this situation before we commence on what could be a long and costly experience.
