Moin, I’m calling from Spain where our family is driving a Córdoba vario tdi, Mkb should be Agr or alh. At the moment it happens sometimes on the highway, which he rarely sees that suddenly the performance goes away. He then stops the speed with difficulty and need, then he can’t make more than 120. Does he have a emergency program? If you turn on the engine from time to time, he pulls it off again. Sometimes the fun then starts again. Sometimes he also drives trouble-free. The crate is from 2001 and has “already” 70000km away. It only drives to the beach or to the restaurant. Longer distances almost never. Most of the time of the year it is standing at the airport. I suspect that something is sitting there, but with the hard-to-precedent error does not like to go blind into a workshop. The following questions: Does he have an emergency program? Does he have an error memory? Will there be anything there? What do you suspect is the cause? What could I test? Merci, ne, Gracias!
