Grinding noise on cold start. When the engine achieves its optimum oil temperature then the noise goes away. It's Audi A4, 2019, B8/8W, 1.4 35TFSI. It has only done 12k KMs and recently engine oil, oil filter and air filter was changed from an Audi dealer.
You also get erratic vibration in your seat on cold start and you feel it when the RPM is back to normal (once you have driven it a bit then seat doesn't vibrate anymore) but there is absolutely no vibration in the steering wheel. Car drives like brand new otherwise. No issues or sounds other than these two mentioned above.
Is this a normal? Can anyone comment please.
