Wow, what a battle
I had my Trol checked for this issue by Nissan from the first time I noticed this. Everytime they come back and tell me it's normal. I even phoned their head office and got in touch with their so-called technical expert in the Western Cape. Although a very friendly guy, that's where it ends
Eventually and loooong overdue, I visited Graham when I was up North on a business trip and arranged - can you believe it - with Peter at Rovertec (Landy workshop) in Hermanus to go through the whole system with Graham's assistance. After testing a few things Peter thought it could be the Purge Valve that was faulty, but the only way to check this was on Nissan's diagnostic system - so I went back to Nissan to check this out. This time I was very adamant, and when they phoned me to say they have tested the purge valve and it was working properly and that I could come fetch the Trol, I said there is no way that I will accept this and for the umpteenth time insisted (this time very, very aggressively) that I would not be satisfied before they went through the whole fuel pressure system from tank to end, and also warned them of some serious consequences if I'm not sattisfied

. After a couple of days the workshop manager phoned me to inform me that the fuel check valve was found to be faulty (pressure test on them revealed this) - and said he thought from the beginning of the whole saga (2years) that this could have been a problem re my compaint - then I flipped - why did he not look at it all the previous times I was there for the same problem !!!!
Now I thought this is the end - but lo and behold, after about a week of waiting for the part with my Trol still at their workshop I phoned to inquire on progress (Note I phoned them not the other way round), they said their "system" could not track progress on when the part will arrive, but they will come back to me. I then ordered them to make the Trollie drivable as I cannot stand to be separated for such a lengthy period and subsequently got it back . Another 10 days passed and again I PHONED THEM (not the other way round) and again they said they will come back to me asap - after 2 more calls within the next day I got a reply - The part will only be here by the end of March !!!! There is'nt one available anywhere in the world and they must get it from their manufacturing plant somewhere in who knows where (thought it could be Mars).
This is Nissan service excellence !!! I'm so gatvol for their lack of ownership and apathy towards their clients, you wouldn't believe.
