In my opinion it is often better than searching for Manufacturer TSB's in Auto Repair Software.
Why? Because all OE's are very cautious about admitting certain parts of the cars are POS and prone to failure, and the dealer's make money on replacement of the parts after the warranties are up. They aren't going to simply release a TSB and say check this known area first before wasting time digging elsewhere, because it could result in an expensive NTSB recall for them to do so . If you are not an expert on a particular car, Do not scoff at experience of some of the Enthusiast Forums and videos put on YouTube to save you time .
