2005 X-trail SVE 2.2dci 103000 miles, owned since 2015 and driven approx. 15000 miles – Chesterfield based
Hi guys just had a scary problem with the vehicle and hoping you can give me some guidance as to a solution!
This afternoon when driving on country lanes at about 50mph, when there was suddenly loss of power and no throttle response. The vehicle slowed but continued to run if the throttle was depressed fully but would only go up to about 20mph. I had to continue like this for about two miles with hazard light on as nowhere safe to stop, uphill it would only go 10mph but luckily there was a layby at the top.I’m guessing this was limp mode? Never experienced it in this car before so not sure – there were no warning lights whatsoever on dash.
It had had a flat battery earlier in the week, which I put down to lack of use, so I first checked the battery with multimeter in layby which was 14.55v running and 12.5v when engine off so seemed ok battery/alternator wise. Restarted the engine, tickover no problem and throttle working fine and car driving great???
Carefully drove home without issue and tried my £30 Autolink AL319 code reader – surprised to see no codes whatsoever and the throttle position data was showing the correct % when depressing the throttle various positions? Gonna call into my friendly local garage in morning see if their expensive code reader brings anything up
Theres a couple of things I’ve thought of which could be related, other than the low battery charge.
Can you please give me some idea as to where to start and what sequence? Was hoping to see some codes to get me going right direction and I know an intermittent fault can be difficult to find. I’m ok with the spanners so happy to try some fixes if anyone can please help!
Searching on this great forum, I can see suggestions for similar faults :-
New air filter ( we service regularly)
Change fuel filter (done maybe 8000 miles ago with genuine Nissan),
New battery (good Varta one fitted 3 years ago)
SCV valve (is this more for the “hunting” problem thank no throttle response?)
Replace TPS/throttle pedal assembly?
Ecu not sending signal to TPS?
Replace Camshaft position sensor?
Replace/unplug MAF see if any different response?
If I can’t sort it myself can anyone suggest a specialist local to Chesterfield/Sheffield?
Its been a great car so far and the Wife loves it so want to make it all better and keep it as long as possible!
Thanks in advance for your time and attention
Pete

- All timed We’ve owned it its “hunted” the revs when cold – was looking at changing the scv soon? Also, rattly engine noise when cold but seems they all do this?
- Maybe 3 times in time We’ve owned it when accelerating through gears and getting to about 60mph its hesitated and wouldn’t go above 60mph (wasn’t anywhere near rev limit) until I changed gears and revved again then was fine?
- Over last few years car had been parked up over the winters 6 months at a time on decent trickle charger while we were working away which I know doesn’t do it any good
