Vibration in Scénic

Hello, I have a scénic diesel 1.9 to which it came out on the panel, check in yecto. I changed the first heater that is molten, but the failure is still coming out, in addition the engine vibrates a lot in idle and the failure code disappears when the engine was heated, I have checked tacos and motor supports not finding any anomaly, the case is that the car is perfect in all situations. It has a way out, it starts well, good power and good sound, will it have dirt or poorly dosed in injectors?
Greetings.

Hello, friend is best to change all the heaters at the same time and if you get out of injection you have or some injector or two in poor condition or the pump or some sensor. A greeting.

Hello, the engine vibrates because of the motor suppression (only in relief)

Hi Tashunka, if the rest of the heaters are fine, disassemble the AG that surely is stuck from the escape. If you have a chance to make an injection check, this will make you walk more.
PS: The AGR is a typical fault of those engines, Salu2: Woohoo:
