They are Bosch agents and have reader for every car, van, bus and truck on planet. When I took mine in they printed off code with technical explanation, then cleared the memory and killed the esp light, then we tried to repeat the fault to bring back the light and recheck the code again, but it never came back on. Nottingham Chrysler wanted £120 to do same thing - Parkinsons charged me £25 + vat. No wonder most of the Chrysler agents went bust!
