Same as my mates Navara...

we diagnosed a snapped alternator shaft (common fault on them supposedly) it still worked but it was making weird noises and we pin pointed it visually..anyway He phones Nissan, tells them what the prob was and if he can book it in for a replacement part as it's covered under warranty. Yes no problem sir, we will plug our diagnostic machine into it at £45.00 and see what the problem is..."Err no you won't, as I have told you what's wrong already, whatesmore how can diagnostic software tell you a metal shaft has snapped?"...we need to do this proceedure it will be £45.00 plus labour.......awayandtakeafucktoyourself
