As always, great service. Beforehand, the malfunctions were read out and this showed that the turbo pressure had recently dropped. Still getting it tuned. Initially, no good results. In the end, the turbocharger’s charge hose turned out to be leaking due to age. These replaced and yep, the old BMW comes along again with the somewhat faster cars on the autobahn. Btw. the car has now driven 331000 km and has been running with the new software for a while. To your complete satisfaction. The engine runs nicer (quieter),pulls much better and has a higher top speed (+/- 225 km/h). Basically, I just have all my old and new Diesels tuned here. Regardless of mileage.
