Technical Trouble with Doblo Maxi 2016

[Mj24]

Hi there,

Recently bought a 2016 doblo Maxi with less than 100km on it.

Engine light kept coming on so the garage replaced something electrical, then something around the starter.

It didn't fix it, and the engine light kept coming on. Then it started losing power, and it's also losing oil somewhere but Internally.

I've since replaced,
Injectors
Turbo
Some thing around the Spark plugs
The Plugs connected to gas pedal
Had the filters cleaned.

It's was going ok for 3 weeks, not sure about the oil yet, but it's losing power again.

Any one any idea what is wrong with this van. Bought it for 6k and spent another 3-4k on repairs. Has my heart broke.

Cheers,

Is the engine light back on? If so do you have any fault codes, or are you able to read them?

Totally that! Do read the error codes stored.

The engine light isn't back on this time, it's just losing power mainly in the 3rd and 5th gear.

Does the losing power feel like a kangarooing effect, like the power comes and goes?

 

[Mj24]

It doesn't feel like kangarooing. Say when I'm in third gear, it can subtly feel like it has less power, and the tone of the engine is higher than normal. Then it can be fine for a minute again, and then change again. So it's not like kangarooing, it's more like longer sequences.

 

[Greasytrucker]

Right. When you say it’s had injectors, were they reconditioned or another used set?

 

[Mj24]

No they were brand new.

I think you need a diagnostic tool and monitor some values while driving. Possible turbo boost leak? Intercooler hole? Pipe split? Throttle body or EGR sticking?
Losing oil could be a blocked turbo return pipe, so it is being forced out into the airflow into the engine. Do you have exhaust smoke?
