Sold my Diesel Cruze. No longer need this gauge. This monitor will tell you when a regen is occurring along with a bunch of other information (Soot level, boost, RPM, EGT, etc). Saved me a bunch of money by letting me know my Cruze Diesel was performing regens every 70 miles or so as opposed to every 700-900 miles. Was able to provide info to the dealer who replaced my air intake pipe, O2 sensor, and reprogrammed the ECU. Currently they're selling on Ebay for $350. I'll let this one go for $250. It's in perfect shape and comes in original box.
