Well I love this car, it runs well and drives very well.. but when I leave the car standing for a while (4,5,6 hours), then start I get the non-autostart issue.. flashing yellow for traction and ABS. If I stop the car, lock it, unlock and start again, the issue goes away, however the stop/start still doesn't work.

Reported codes(there are a few):
U100001 - communication CAN circuit
C170400 - Left front low air pressure
U0121 - Multiplexed traction control connection
P0470 - Turbine upstream pressure senser
P1525 - Consistent multiplex signals for cc/SYL
P0135 - Proportional richness sensor heating circuit
P1503 - Air vent control

I've changed the battery, I've also cleaned the turbine sensor pipe, and currently running DPF additive.

I'd love to get this car in good order, as I plan to keep is long term when back in the country.

On another note, has anyone noticed a difference when riding with 17" or 19" wheels.. it's curently a very cushioned ride with 17" wheels, and thinking or upgrading providing the comfort isn't jeopadized.

Welcome to this forum.

Hopefully calnorth will be along shortly on the technical front.

On the wheel front, yes, you'll notice a difference - maybe a change to 18" would be the happy medium?

Thanks: gloucester - I thought the same thing on the 18" wheels, happy medium.. thought I'd check to see what other have experienced first.

On aother note, how do you feel on the steering? For me I find it loose.. can this be tightened does anyone know?

I didn't find anything amiss with the steering feel. Mine did start squeaking and a bush was replaced under warranty, but the feel was unaffected.

You haven't given many details about what car you have and its age/ mileage etc. Recent MoT?

No idea on this other than: U100001 - communication CAN circuit

Nissan describes U1001 CAN COMM CIRCUIT as:

"When ECM is not transmitting or receiving CAN communi-
cation signal other than OBD (emission-related diagnosis)
for 2 seconds or more".

This is a CONSULT Test response and which would assist faulty items (Control Modules) detection. Without CONSULT we are stuffed.

I'm going to check the wiring this week. I have a feeling there has been some works done poorly. Anyway, still love the car. Cheers all

The last 3 errors seem to be on the fuelling system?
