Asked by Ajay Doyle
There's rather a large amount of smoke coming out of the exhaust of my 2003 Nissan X-Trail when I start the car or accelerate. Are there any problems with the 2003 X-Trail I should know about, or could it be a mechanical problem?
Answered by CarsGuide
24 May 2011Since we last responded to your question we have found out that the X-Trail does have an issue with the breakdown of the catalytic converters in the exhaust system, and the abrasive powder formed can be sucked back into the engine because of the valve overlap Nissan employs to control NOx. Once in the engine it can cause rapid wear of the bores and rings, and the oil trial like yours shows.
