This sounds like the same experience people have with their out-of-warranty german cars. Either take it to the stealership or buy diagnostic system made by non-VW guys. Even if you have the diagnostic system to read codes from ECU, you are left wih testing many sensors: whether the sensor needs to be replaced or cleaned. But one has to know the details of resistance etc to test the said sensor.
And these sensors are not cheap. They cost more than a tire!!
- bri3d 12y agoI actually find new electronic automotive systems to be easier than the "old way" (tracing wires, probing with a multimeter, etc.): oftentimes the issue will have diagnosed itself, and, if not, the ECU diagnostic tool will have an actual value display and a list of actuators you can hit to see if the sensor responds appropriately. I've never seen a sensor that's more than about $150, but I'm sure they're out there. The frustrating part (which is indeed common to German cars and high-end tractors) is that the diagnostic systems are all loaded with unnecessary and ridiculous manufacturer protectionism. You can't even clear the "Change Oil" light on a new Porsche without a Porsche diagnostic system or the reverse-engineered clone tool (Durametric). And even once you've found a broken sensor or component, it's often pointlessly "coded" (its serial number written into an EEPROM) such that the factory diagnostics tool needs to bless its replacement.
