Technical Hi! Doblo cold start problems

[skracing]

Hi all suffering cold start up issue. 1.6 multijet and ducato. Finally solved. I have carried out many electrical tests obd diagnostics fuel pipe checking etc. Nothing found. After a conversation with an old guy at the MOT station. Problem solved. The one test to carry out is injector leak off. Or have them overhauled or fit s/e or new. Less messing about because you will find more than one will have excessive leak by and you'll end up needing to replace or repair all 4 anyway. Hope that makes sense and solves your problem.

Was yours higher mileage? The OP's was only 42K miles I think.
Leak off test is a good simple check for injectors, but unlucky if vehicle is under 100k+ miles I would have thought.

Got 3 doblos on the fleet. This one with starting fault high miles. But I'd say never say never. 1.3 been using oil since new. Had new turbo and dpf. Dealer now say 1ltr per 1200 miles fine. I Clean out dpf once a month.sure this is a build problem. Not long before I part ex it. Newest to the fleet 1.6 keeps having eml on. Had oxygen sensors map maf dpf & cat clean. Fuel consumption terrible. Sure its injectors as well probably cheap fuel before i took ownership. The ducato 11700m has had 3 sets of injectors 2 under warranty before 70000. Fault non start. Apparently cheap fuel wears them out really quickly. This winter started lumpy and no throttle response. As per mot man's advice s/e set fitted problem solved. My point never trust what you start with is right and buy quality fuel.

Question..

Would rail pressure plummet with a parked vehicle just shut off...?


Like switching off your garden hose.. But leaving the nozzle dribbling

Might be something you did.. Or didn't.. Look at..?

Daughter had a tired 06 1.3 Grande Punto multijet 100k + miles pre DPF oil level never fell, but I suspected it was being topped up by the injectors, so I changed oil frequently as cheapest option and had read about "running away" diesels.
I had a new customer for a head gasket job on a Scudo that did just that, which was fun, turned out he had never changed the oil in 70k, serviced it himself??? Just topped up oil. Inlet manifold was full of oil which fed the engine with ignition off, I had to stall it quickly!!! The engine was so worn by his "servicing regime" that engine breather topped up the inlet manifold with oil which it then "ran away" with.
My 1.6 Doblo multijet, MAP error codes, black smoke etc. turned out to be a leaking gasket at the inlet manifold for the EGR cooler losing turbo pressure.
Modern common rail with extremely high pressure injection systems are really efficient but a lot less forgiving than the older systems given their fine tolerances.

I change oil every 10,000 now.

I change oil every 10,000 now.

I change oil on my vehicle more often , but in fairness do less than used to so I just go by the colour and smell on the dipstick.

Tengo 3 Doblos en la flota. Este con falla de arranque y alto kilometraje. Pero yo diría nunca digas nunca. El 1.3 ha estado usando aceite desde nuevo. Tenía turbo y DPF nuevos. El concesionario ahora dice que 1 litro por cada 1200 millas está bien. Limpio el DPF una vez al mes. Seguro que es un problema de fabricación. No falta mucho para que lo desguace. El más nuevo de la flota, el 1.6, sigue teniendo el EML encendido. Tenía sensores de oxígeno, mapa MAF, DPF y limpieza del catalizador. El consumo de combustible es terrible. Seguro que también son los inyectores, probablemente el combustible barato antes de que me hiciera cargo. El Ducato 11700m ha tenido 3 juegos de inyectores, 2 en garantía antes de los 70000. Fallo de no arranque. Aparentemente, el combustible barato los desgasta muy rápido. Este invierno empezó con grumos y sin respuesta del acelerador. Siguiendo el consejo del hombre de la ITV, se instaló el juego de juntas tóricas, problema resuelto. Mi punto es que nunca confíes en lo que empiezas y compra combustible de calidad.

I'm not clear on how you solved the problem, could you explain it to me?

Hey all, I recently purchased a 2014 doblo 1.6 multi jet and I have an issue that my local garage can’t seem to pinpoint.

Each morning after sitting overnight I’ll start it up and it will sound like not all pistons are firing properly and the gas pedal won’t do anything it just sounds like the engine is struggling to turn along with this it emits a cloud of blue smoke. If I leave it for about 15 seconds the revs will jump slightly and it will start idling normally and the smoke stops. It only does this after being sat overnight it will start normally through the day, it doesn’t do it every morning maby 1 in 10 times it starts normally seems like if the temperature overnight has been quite warm it will start fine.

Would anyone have any insight into this?

Thank you

hi, you solve the problem?

My van has done exactly the same for months and been in many different garages and nobody seems to be getting to the bottom of it

So far I’ve had

New egr valve
Air filter
Fuel filter
Maf sensor
New glo plug
Intake manifold cleaned

It’s really doing my head in now, so please if anyone has an answer to the original question I’d really really appreciate it

hi, you solve the problem?
