Before today, I was (sort of) convinced that Nissan main dealers were "expert" in Nissan motors and that this justified using them to service my Patrol. Now, I have cause to worry .......... 
Last week, I had Westway Nissan in Oldham service my 2005 Patrol 3.0Di SVE. At the same time, I asked them to checkout a fault - engine suddenly losing power when overtaking or powering up hill at around 2600rpm. When booking the car in, I reminded them that I had an identical problem about 12 months ago that was cured by fitting a new MAP sensor (aka boost sensor - measures manifold pressure & hence boost pressure). I also suggested that, as the car was otherwise running fine, the most likely problem this time was that the sensor had failed again. They agreed to swap the sensor under warranty. :thumb2
As it happened, they couldn't replace the sensor on the same day as the service, either because they had ordered the wrong one - or because the wrong one had arrived. Eventually, the correct boost sensor did arrive and I took the motor in this morning for them to fit it. I sat in reception watching TV, as the job only takes about 10 mins.
After about an hour, I was told that they'd fitted the new sensor and were about to wash the car (they do that for free every time I take it in). I asked the chap in reception whether they had cleared the 0905 ECU fault code. He popped down to the workshop to check and re-appeared a couple of minutes later with the mechanic who had changed the sensor. The mechanic explained that he couldn't either read or clear ECU fault codes on the Patrol. He thought there might be a fault on the diagnostics on my Patrol. This is very odd, as the dodge using a shorting link between pins 1 and 8 of the diagnostics socket to put the ECU in diagnostics mode works fine. I explained to the mechanic how I checked and could clear ECU codes - and he developed a sort of goofy look (a "don't know what you are talking about squire" sort of look). He then went away.
A few minutes later it occured to me that maybe they were trying to use a Consult III diagnostics tool (which doesn't work on a 2005 Patrol) rather than a Consult II (which does work). It turns out that I was right. Not only that, but it seems that Westway Nissan, Oldham may not have a functioning Consult II (as they still couldn't read ECU codes), so they cannot do engine diagnostics on any Nissan built before 2007.
I'm not sure what I should think about this - but such thoughts as I do have are not very positive. Has anyone got any (printable) thoughts about this saga? Do any of you chaps with a (recent-ish) Terrano or Patrol use a Nissan franchise dealer?
