Xtronic manual changes

[scimitargtc]

2016 teckna 20k bought at 6 months old with 6 k. Great car if mpg not great circa 43 mpg but it’s an auto ( ok my company Audi A4 2.0 ultra auto did 57 mpg all day long) but as I have just retired she’s gone back so investigating options realised using manual mode gives me 55 mpg BUT I’ve noticed if I can’t change up due to speed I get a beep but if it stays in n say 5th or 6th for a short distance accelerate and try to change up it won’t I either have to whack it back into auto or drop it a gear on the lever when she’ll then happily change up.?...

Had it at dealer today armed with tube video of the issue asking that they check the software for updates all ok no updates needed mentioned the box has a 5 year warranty?? Car still in manu warranty anyway and as they said now it’s in the system should it fail Nissan are aware it’s been queried..

I had exactly the same problem, fighted with Nissan 3 long years till warranty expired. I asked politely my dealer in Hamburg to update ECM, TCM and IPDM units with the latest firmware which they did without me paying for this and I can confirm that the latest TCM update already fix this "unable to shift up" issue.
