Transit mk7 2.4 tdci new turbo no start

[Fry126]

Hi, I have a transit mk7 2.4 tdci 2010 2 days ago there was a strange noise from my turbo then lots of smoke I pulled over and the engine cut out I checked and there hardly any oil so I topped the oil up and it started straight up again I then turned it off and got recovered. The following day I was having a look over and my exhaust was full of oil I then took the turbo of and there was lots of play so I replaced with a new turbo cleaned the intercooler out and tried to start it it fires up and runs for about 2 seconds then cuts out! I then got it started and it was running and reving I then turned it off tried to start again and now won’t start at all!! Any help or advice would be much appreciated thanks

Exactly what happens when you try to start it?

[Fry126]

It turns over starts up runs for 2 seconds then cuts out! But when it runs for them 2 seconds the rev counter doesn’t move

In that case it sounds like you may have disturbed a plug onto an engine sensor while in there doing the turbo.

If it kicks in for a couple of seconds I would suggest it may have a breathing problem.


Either something in the exhaust blocked when the turbo failed or there is a restriction in the inlet or maybe EGR valve stuck open.


Most sensor faults would either keep running but badly or not kick in the first place. Only obvious exception might be the airflow meter, if that was faulty or more likely if one of the intake hoses was not connected properly (or if air couldn’t get through) then the reading would be low and it could cut as you described.

AFM is what I was primarily eluding to but didn't want to get too technical for the OP in case he didn't know what it was.

Obviously AFM will also be pretty much closest to the inlet side of the turbo, and 100% likely to be easily disturbed on the OP's job.
