159 2.0JTDm misfire/hesitation
Had my 159 for about 10 weeks now and here's my first 'problem'.
It started about a month after I got it but it was so infrequent then to not cause any concern, but now it's happening almost every time I drive it;
When cruising along at very light load I get a hesitancy/misfire where the car will lurch back and forth as the engine loses and gains power momentarily. This isn't just a short hiccup, but something you can hVe for many minutes under these conditions. Usually happens at about 1500 rpm or thereabouts, can happen in any gear.
However, it's only happening under very light loads. If you lift off completely and coast it's fine. If you accelerate more (even if it's only very light acceleration) then it fine. If you're just maintaining a set speed at a low rpm cruise on a level road (I.e. Very light engine load) then this issue can occur.
Also, it typically occured only during the engine warm-up cycle when the engine is below normal operating temperature. It only ever occurred like this but recently it's started to do it when fully warm aswell.
Is this a known issue ? Any pointers appreciated before it goes back to the main dealer under warranty. Thanks!
