Hi All

When driving on the motorway between 60-65 it feels like the engine has a heartbeat and is pulsing its barely noticeable it runs fine at idle and even revs fine but wondered if anyone had experienced the same.

Ihad simalar with the first 406 d9 ihad,

it was fine after the fuel filter was replaced,.

So if yours hasnt been changed in a while it might be worth changing it,

It feels like a tugging feeling most noticeable on smooth but "uneven" roads its very faint, i will try the fuel filter as havent replaced mine for 18 months so definately worth a try
