Hi, I'm sorry to say I never did. It remains a mystery. If you look back thru this thread you'll see II tried everything and spent months on it. Two garages, including a Nissan dealer couldn't fix it and gave up. I did use the petrol workaround for 2 months but eventually it got worse and it...

Hi, I have come back to this problem now I have more time. Meantime, I have been using the 'fuel on filter' workaround just to cold start in the mornings and its been fine. I have noticed in the live data on my OBD2 reader has the following: IAT(°C) 29 (Inlet Air Temp) ECT(°C) 27...

Hi Max, I have a nagging problem with my K12 that is well documented in the discussion "Engine only runs with throttle position sensor disconnedted??" The title of which is misleading. In short, the car will not start when cold in the morning, but once started with some difficulty (with a...

Local garage has pro Bosch diagnostic system. Came up with no faults at all. Even my basic Autolink shows an amber (pending) fault. Anybody have any ideas at all how I can get a Consult 2 type diagnosis without having to spend £150+?

I drilled a hole in the top of the airbox so I can spray petrol in easily every morning. It's a workaround that might go on for a while I fear.... This time of year, once its started in the morning its good all day.

I could ask my local garage if they have a pro reader. It won't be a Consult but it might come up with something. When I disconnect the Temp Sensor I get the corresponding fault code so that would suggest the connection is good?

Car still runs great all day once started in the morning. This still points to a "cold start enrichment" problem... Any other ideas if its not the temp sensor?

My code reader gives me no fault codes but gives an AMBER warning, and no explanation. Would the torque app detect that?

Thanks Frank. Crankshaft PS fault code turned out to be correct. I had already changed the sensor (for a used part from ebay), so I change it back to the original and the coughing and the code went away. So I had introduced another fault with a used part.... I despair. New coolant temp sensor...

Thanks for that. I checked it out, see photo, Only superficial corrosion. The top link is also fine although not shown in the photo. Inevitably broke the transparent plastic cover. Really bad design. Lashed it up with some cable ties. The batter has been disconnected too many times during...

Got this live data from the engine whilst it was idling. Is there anything that stands out?

Is there a known reader that works on the K12 that I can buy? Otherwise I have to find a garage. I can't go the Nissan dealer, they told me it needed a new engine!!! useless. If it was a Crankshaft PS fault, would that suggest it's the timing chain? or is that normally associated with a...

Booked the car in for its (French) MOT this morning. Started the car with the petrol on filter trick no problem first thing. So set out for the MOT, just out of the gate engine starts coughing and Check Engine light comes on. You couldn't make this stuff up!!! So back home and check the codes...

Bought this Autolink AL319 reader under a year ago. Do you mean if the Engine Check light is on it should detect a code?

The coolant temp sensor checks out ok when I tested it, but I have a new one on order. I installed a new fuel pump, and there is pressure in the line. It sprays out everywhere when I disconnect it. What is leak back?

Ft The petrol on filter started it see my reply to Frank. I runs smoothly so i'd like to think we can rule out the timing chain. What do you think? This would be a gradual degradation of performance right which I never had. I bought a replacement ECU (cloned from my own) from CarTech. This...

OK.... put petrol on the air filter and it started almost immediately then continued to run even when I removed the filter. It ran smoothly and also restarted after I stopped it. Idle speed normal. So this looks like " lack of coldstart enrichment " right? What would cause that? I do have the...

ce Hi Frank, Is it possible all this could be due to timing chain stretch? I read alot about it for the K12. But when it was running recently, for a couple of days (after the throttle position relearn), it was running and starting great, plus I have no error codes. If it was timing chain it...

Right... I read on this forum that the coolant temp sensor is an input for the ECU for cold starting etc. so I understand that if it was faulty would cause starting problems. I am waiting for the new sensor to arrive, so removed the old sensor and tested it against these figures I found on this...

OK cool. I already changed the MAF. I removed the connector for the coolant temp sensor and it throws a code. So the wiring is good. No fault code when its connected but I am guessing on a car of this age the fault reporting is not that sophisticated, so it could be faulty and not produce a...
