Additional Notes

Complaint: Smog Diagnostic Specialists located @ **** ********* **** *****,are crooks they will failed my car on a visual inspection while telling me, I needed a diagnostic for $85 and a re-test for $35. I paid the $49 for the initial smog and refused their fake offer. After I left their phony smog inspection, within the same hour I took my car to Northgate Smog and passed. beware of these crooks...I've also filed a complaint with the bureau of Automotive Repair, their investigation has determined my complaint was valid. Smog Diagnostic Specialists has refused to refund my money, so I will now file a small claim against this company.

Desired Settlement: I would like a refund as well as my time off work for the Inspection time of my vehicle, and incurred court cost.

Business Response:

***** ****'s ********** Jetta failed for visible smoke test portion of the test which is tested by snapping the throttle and seeing how much exhaust smoke if any comes from exhaust pipe, there was excessive smoke coming from the car's exhaust pipe of *****'s car. The gentleman that brought the car in for the inspection was watching the inspection on the car and commented that the car never smoked like that before (he saw the excessive amount of smoke). The vehicle also failed for an air intake tube not completely connected and missing a retaining clamp. Vehicle passed at another location and the gentleman came back into the shop and demanded his money back and accused the smog technician of being racist (not that this even matters). The bureau of automotive repair did get involved and the B.A.R. representative said that it did smoke but after three snaps the smoke did go away, but was passed for the smoke and failed for a modified catalytic convertor. In closing the car should have not been certified. We at Smog Diagnostics are fair in our business transactions all tests are conducted according to the state of California's standards. Thank You ****** *****
