Hi I'm new here and am just wondering if someone has any idea of the different types of scanner tools there are out there. I heard there are also tuning computer tools for the cars but not sure about what one's are available and how much they cost but would like a list. I think I need one cause I'm working alone and noticed a couple threads that talk about the ross tech vcds for boost leaks before you get into working on the car. Now to get to one of my main problems. I am trying to safety my vehicle and it has an engine code on it. The mechanics are required by law to not pass the car with this damn engine code. It says 1899L Turbo Boost Circut 16486 MAF Sensor came back after clearing on the work sheet. Here's what I've experienced with the car over the last 2 years I've had it. When I first got the car it had an engine light on. Turbo boost position sensor out of alignment or something like that. It didn't go into limp mode until after about 3 months of having the car. But I heard from a friend that running high RPM's that it would clean out the turbo. So I did that and it would go into limp mode and out of limp mode every once in a while. I finally took a look underneath the car about about 8 months and found a couple wires that hook up to the turbo that were cut. I just stripped them and twisted them haphazardly together and haven't looked since to see if they are together but codes were still on after connecting them and I was pretty sure they were connected good. It was really hard for me to find the end of the wires and if I could just disconnect them and put new ones in to turbo? So after all that I have been driving it like that since and haven't had limp mode come back on for about a year now. One thing I did notice is that my turbo has a lag in it. And I watching a video from a guy on here about the 4 different problems that could cause my turbo to malfunction and I was thinking that it was because of the stop screw. So when reading about how to fix the problem it talked about the vcds scanner cable from ross tech. I've seen an OBD II for $30 not sure if that does the same thing? But if you have any info that would be appreciated. Thanks!
