Hi guys

Had my XT since June and have been really happy with it other than on two occasions there has been a real lack of power / jerkiness in 3-6th gears.

First time was in September on the way home from Newcastle Airport with the cruise control on. It suddenly dropped out of the cruise control and started running like a dog. I could not get the cruise control back on - the set light kept flashing but would not let me set it. I had to drop gears to get up some of the hills. The next day everything was absolutely fine.

The same thing happened again this morning (I wasnt using cruise control though). I made a journey of about 7 miles. No problem. Had a meeting and then left two hours later. On the return journey it started running like a dog again. No real power from third gear onwards.

Any suggestions? It is due for a service in 2 weeks time. 57 plate diesel dci sport and 21k on the clock. Previous services have been Nissan dealers.

TIA

'Limp mode'...presume you had a MIL showing? (Engine check light) - sounds like possibly needs a code read...

make sure the fuel filter has been or is changed at the service, not pointing fingers but i know a number of times one of the leading main dealers in the north east has claimed that fuel filter was changed at a service and it hadnt been.....mine was one of them

Thanks guys

No lights showing whatsoever.

Just took it out before. Was ok for a couple of minutes and then started to get a bit jerky. Cruise control was settable when I set off (I didnt set it though cos I was in a 30mph), but a few minutes in the 'Set' light was flashing and it could not be enabled.

Hi

I have had the same problem (2003 2.2 SE diesel), ie apparent rough running, then occasionally over last few months approximately 80% loss of power. Latter incidents were short-lived however and garages could find no problem (even local Nissan garage after vehicle recovered by breakdown service and taken 30 miles to garage). In last few days problem occurred but did not resolve and vehicle again recovered to local garage which had encountered same problem with an Xtrail a few months ago so quickly diagnosed, repair carried out within a couple of days and it is now running as lot better than for a long while. Problem was that replacement part (accelerator pedal and integral electrical connection (a modest sized and reasonably uncomplicated item) cost just under £500 inclusive of VAT plus a modest amount of labour!!

Thanks for this - I will mention it at the garage when I take it in, and report back here when they diagnose the issue.

I guess this kind of thing will not generate error codes in the ECU?

Cheers

On the T30 2nd service (24000miles/2years)changing the fuel filter and brake fluid is an extra which some dealers seem to ignore/or are ignorant of.Happened to me.I also stopped buying Tesco diesel(same forecourt/same pump) after having my fuel filter clog up for the second time after only 14000 miles.Car goes into limp mode,max revs about 2000.Hope thats all it is for you.

If it really is a clog up issue, other than changing the fuel filter, my current fav cure-all remedy (nope, not on commission) might also help?: BG44K for petrol or BG244 for diesels (former will actually work for both...) : http://www.powerenhancer.co.uk/news/bg- ... diesel/33/

Certainly making our T31 run more smoothly - halfway through BG244-fortified tankful (longer you can make tank last, the better...apparently)

Thanks Aitch - I will order some today!

Right guys - MIL light came on before as soon as I started it.

Drove it and it seem to run ok'ish, but with not the power it should have. It certainly let me do more than 2000 revs.

Dont need to use it tomorrow, but do need to a 40 mile round trip on Saturday - 90% on dual carriageway / motorway.

Am I safe to do this and then take it in the garage Monday (I'll drive gently)?

And, on the positive side, does the MIL mean that an error code will have been generated and the garage will be able to find the problem quicker?

Cheers
