The reason for the acquisition is as it should be otherwise, the famous yellow check lamp, here at our Lupo 1.0 AUC. The device can read in contrast to all other inexpensive diagnostic equipment and ABS, automatic transmission and airbag. Of course, only at VAG vehicles. The handling is extremely simple and almost self-explanatory, the language on the diagnostic display is German! The menu is in the above-mentioned 4 groups split where the errors are stored. The enclosed CD is also in German and includes the manual and all VAG fault code (ca.4000-5000). I printed out the list and filed in a folder (80 pages) simplifies the handling of the vehicle. Another note, no longer results in an error in three cycles, goes from the lamp itself, the error remains in memory. Men should also know the various components after replacing new must be "taught". This may not be the device. Even the deletion of the service / inspection display is not possible, that is only about Tastenkobination tacho / ignition or professional testers. With us is the EGR valve of the culprits, it was stored with three different codes, but is not active again occurred. A cleaning of the exhaust gas recirculation, we fix the problem permanently. So for mechatronics a very cheap way of diagnosis, as described the hobbyists should after recognizing the error, read only at times clever, plus there are enough forums.
