Light vibration between 3000 and 4000 RPM! HELP! SOLUTION!

After much deliberation and a vacation spent in the workshop, the problem is finally resolved.

The cause of the rattling was the output from the STG's mass flow meter!! 'Furthermore, the diesel pump was replaced at the same time, as its fuel injection control system was also no longer functioning optimally due to the high mileage, although this did not necessarily affect the rough running issue.'

If you're at a loss with your diesel engine and need a reliable service provider in the Nuremberg area, please contact me via private message. Here, you will receive fair assistance and not be ripped off like some repair shops that carry out fault diagnosis by random principle

Best regards

Ah, one more thing I forgot to mention: the fault at the LMM signal output was 99% due to a high voltage issue when the new side part was being installed by the mechanic, as they hadn't disconnected the battery and ECU during the welding process!!

Therefore, it also explains why the LMM was also defective after the accident repair...

Such an incident should serve as a reminder of how much trust one can place in a trusted business partner.

Best regards
