Nissan XTrail 2010: Solutions for Check Engine Light, Power Loss, Jerking, Fuel Consumption, and Strange Noise Issues

Hey, I had a similar situation with my 2008 Nissan Qashqai, running on petrol though. I'm halfway decent when it comes to mechanical stuff, like your typical driveway mechanic. But in my case, the culprit was indeed a defective cable/plug, making the engine act all sorts of crazy, pretty much like what you explained. I took it to my local garage, it cost me 95 Euro to get it all squared away. By the way, do you happen to know your engine type and trim level? That info might help in tailoring a more precise response to your situation. Good luck!

Hey there, Thanks for your insight! Good to see I'm not the only one dealing with such an issue. My XTrail is a gas guzzler for sure, and it's a 2.5L engine. And the last time I took her for servicing was around the 144109 KM mark, pretty recently I guess. Got all the typical stuff done- oil change, new filters, and even replaced my break pads. But this issue came up after the service, so I'm thinking it might not be related to standard maintenance stuff. Hope this gives a clearer picture of the problem I'm facing. So you reckon it's a defective cable/plug issue, huh? I'll definitely get it checked out. Thanks for your help!

Hey again, Yep, your additional info definitely helps. The fact that it's a 2.5L engine and it's happening post-service could potentially indicate that something was not properly put back or tightened down during your last oil change or maintenance - hoses can get bumped, wires can get shifted, you know the drill. But yeah, from my own experience, the erratic behaviour of your XTrail does seem to lean more towards a knock sensor issue, same as mine. Thing is, it won't necessarily be a faulty sensor, could be just the wiring around it or even something else entirely that's triggering the same symptoms. It's kinda tricky, these electronic parts are all interconnected and one can influence the behavior of another. My advice is, just like before, try to get it checked out by a professional mechanic if you can, especially because you've got a gas fuel system and those usually involve more nitty-gritty. Just tell 'em to ensure they check the knock sensor and its surrounding components. Hang in there. Don't let the ol' XTrail beat you! Let me know how it turns out, yeah? Good luck and I hope it's nothing too serious. Fingers crossed!

Hey, Appreciate your detailed explanation and tips. Like you said, it could be a number of things causing this, and we can't rule out a knock-on effect from other parts. I bet you're right about something not being re-fitted correctly after the service. Can't stand it when that happens! Definitely, a professional opinion might be a good shout. I'd hate to start replacing parts and making unnecessary costs. Your advice makes total sense, I'll ask them to give the knock sensor and the surrounding components a once-over. Cheers for the moral support. I’ll surely let you know how it goes. Hope my beloved XTrail can live up to its name and stay strong on the trails! Crossing my fingers and onto the next step! Take care.
