unrunder Motorlauf,ESP? Diagnose per OBD -WER ANALYSIERT LOG | Posts 16+

After a phone call with the master mechanic of my workshop, I believe that the problems are likely caused solely by air in the vacuum line (VL) under higher loads. Therefore, I need to find a way to address this issue first.
"Could someone perhaps tell me how much fuel the VP44 injects at full load in my vehicle? It's already injecting 150 liters per hour at idle."

How about putting a transparent piece of fuel hose inside the car and giving it full throttle?

Best regards, Rainer.

Initially, I had planned to use transparent PA tubing for the engine compartment, but 1. it was very inflexible (especially in cold weather), and 2. it was difficult to get a good seal.
"Before the ESP (Electrostatic Precipitator), there's a transparent section that is factory-installed. And when you accelerate, you sometimes see bubbles forming in it (but not when the system is idle). I suspect the filter head."
