Our assessment fee is $150 + GST. If you choose to proceed with the repair, this fee is applied towards the total repair cost. It is only charged separately if you decide not to proceed after the assessment.
These ECUs are very common to fail after the ignition coil sorts out; the spark plug has not been changed and draws more current!
So the Coil needs to be replaced along with the spark plugs, but the customer presumably already knows this from changing the spark plugs to see if that would solve the misfire!
Some part numbers we have commonly seen on these ECUs; however, not limited to, as they all look visually the same, being the type of DME they are, the control circuits are the same.
