What's wrong with a Scooby. Mine was faster than a Zed and handled better on any average UK road..
nothing wrong with the Scoobies , just soo ugly and ubiquitous
I think with you having a UK alarm system fitted it has interfered with the original Jap system.. mine just has the Jap system that works from the original Nissan key
does it look like this one nixy ?
if so its to enable / disable auto folding mirror option on locking and also autodip when engaging reverse gear
Well it does on mine anyway
Sorry I cant answer your question ,
But I have only used the cheapest petrol in my Zed since I have had it..doesnt seem to worry it one bit, I think the petrol co's make enough profit without swelling their coffers further
if the windscreen is actually marked as opposed to just a dirt film on it, try "jewellers rouge" to polish off any wiper marks or ask someone in the windscreen fitting trade for some of their windscreen polishing paste
