Nissan Titan Diesel Engine Mount Error

Interesting. I had similar symptoms with my old BMW 3 series. Is the vibration worse when the engine is under load? It might also be worth checking the transmission mount as well, as mount failures can transmit strange vibrations.

Thanks for the tip! I will check the transmission mount as well. Yes, the vibration increases under load. The error log mentioned the engine mount specifically, though. Is it possible that a faulty plug connection would also cause these symptoms?

A faulty plug connection could definitely cause the error code and vibration. It might be intermittently losing connection. Given the symptoms and the error code, it is very likely you have a defective engine mount. I'd suggest getting it checked professionally.

Thanks! Following your advice, I took it to the shop. Turns out a cable for the engine mount was indeed defective, as suspected. Repair cost 95€. All fixed now!
