Even with complex adjustments to the chip you considerably cheaper get away as a new supply + installation and adjustment at the friendly dealers. If you’re lucky, a speedometer can be also repaired what almost never offered a contract workshop. There are cold solder joints, failed LEDs, stepper motors, for all appropriate repair facilities and spare parts. In the adjustment, then reinstated the original km value and ensures the cooperation of the speedometer with the rest of the vehicle’s electronic system. Mistake number 3 – “mileage is always detectable and trouble at the sale of the car” If there is a tachometer by the recyclers, good speedometer adjuster can adjust these very often exactly to the value from other stores of the vehicle. Usually, the setting on the exact mileage is not even needed, since in modern vehicles, all electronic components communicate with each other.
A replaced component E.g. with 0 is programmed then miles, thereby automatically corrects its value from the memory of the other modules. The dealer can determine though about the serial number of the component in the vehicle history report the Exchange, but no way to doubt the mileage, if everything has been correctly programmed. You can offer so later your car all alone, without having to fear any claims of the buyer. Conclusion: Often people do not know that you can save money with parts from the junkyard just because incorrect information may hold for the purchase of new parts. For the lower mileage correction must not go also abroad, because it is perfectly legal for repair purposes in Germany. If you have problems with the car electronics, so ask a recycler and a professional speedometer adjuster rather once, whether they can resolve your damage not cheaper than the garage of your car dealer. 2010, Alexander Herrmann
