Disadvantages of the VW AKU engine
- This diesel engine is distinguished by a phlegmatic character, but great endurance and resource;
- In winter, the engine may not start well due to the failure of the temperature sensor;
- The culprit for traction failures and floating engine speeds is usually a clogged EGR valve;
- One of the nozzles here is equipped with an injection sensor, which often breaks the winding;
- The remaining problems of this unit are associated with malfunctions of the Bosch VP37 injection pump.
