Require ans. 4 Peugeot 406 rattling noise on high speed.

[veerran]

I Require reasons or reason for my 2007 Peugeot 406 to make noise on high speed.

the high speed noise is like something is rattling in the engine.

Can this problem wait till i can get some solution online or do i immediately take it to a workshop to fix the problem.

If its wobbling in different speed bands like 80-100 it wobbles, then 100-120 it doesnt and then again 120 - 140 it wobbles. This is completely because tires aren't balanced. Get your tire balance and it will be fine.

If rattling in engine what you say is precisely rattling sound of something is vibrating in the engine, then better seek a mechanic help sooner than later. I doubt it could be some loose belt pulley which is making noise only on high rpm = high speed, or something else mechanic can only comment by seeing it or hearing it in person.
