Hello, I have a problem ... sometimes (not always) when the car is driving on the route are miliseconds kicks of the engine.( Without sound , only power loss for miliseconds) Then faster the speed of the car , the greater the engine kicks. Most often for a hot engine or on warm days. Sometimes there are kicks engine on the route , I stopped the car , turn off engine for 15 minutes and then am driving 200km without kicks and power loss..
I disconnected the air flow meter - it does not help. Diagnostics - everything perfect.
BMW E60 Diesel , 2.5D , Mechanics . Thank you for any information.
