Guest Murat_idil Posted May 16, 2006 (edited) Hi friends, My car is 205 gti, 1.9 D6B, with videos above, you can see mycar's carbon values with old and new values. I converted my car exhaust and filter kit to original one.Due to the fact that I want to solve the problem about carbon values, I went to Bosch service. I wonder these; Bosch stuff said that my car's PPM value (HC value) is normal between 0 .. 300 ppm. Bosch stuff could decrease CO value to %1,1.5 however its old value was %5. HC measurement results between 500 .. 700 at 1000 rpm. at 4000 rpm , this HC value decreases to 250 ppm. I want to know What is the right values for my car? Thanks alot.. before http://www.hemenpaylas.com/download/721064...11.3gp.html> after http://www.hemenpaylas.com/download/721088/MOV00012.3gp.html Edited May 16, 2006 by Murat_idil Share this post Link to post Share on other sites
