Thread: Problem with 2.4L Powered Defender

Sounds like vcv....

Sent from my SM-G925I using AULRO mobile app

Changed your fuel filter lately?
Could also be a bad tank of fuel.

I topped up the fuel (50l out of 120l) before I left Brisbane, so I did over 100Km before it started showing any symptoms.

I am planning to try and drain some out of the bottom of the filter as I am not sure when it was last done but I think it was about 10000Km ago and I have done a trip through central Australia a couple of months ago of 7500KM.

I was planning to do the filter as I have an glass bowl to add to the bottom of it just work has been hectic so a lot of things didn't get done.

Thanks

As the others have said, change your fuel filter, then fit the new VCV when it arrives. The VCV is very susceptible to contaminated fuel, and it doesn't take much to kill it.

I had the same problem with my 2.4 awhile ago, and changing the VCV then a pump learn fixed my issues. Hope you get it sorted.

I need to get onto it tomorrow to get the filter and another vcv in case the other takes too long to arrive (from OS) as none of the normal retailers could seem to do either.

Is there anything else I am going to need to do such as emptying the whole fuel system?

I hopefully will have this sorted by next weekend and will go then.


Thanks

Richard

I change my fuel filter every 10,000k's when I service the vehicle.

My vehicle has an aftermarket Long Ranger tank, which is easy to drain. The standard tank is a pain to empty. At this stage probably change the filter a couple or so times within the 10k period.
Depending on whether you believe in it or not, plenty of threads on it , you can also throw in some fuel system cleaner. Usually just before I change out the filter, I bung some of this into the tank, Complete Fuel System Cleaner Diesel - Wynn's Australia. There's plenty of similar products out there.

I got my VCV from overseas, some Transit store in the UK, but I know of at least two people who have used United Fuel Injection in WA and highly recommend them. The price is a bit more, but you may get it quicker than from OS. LAND ROVER DEFENDER 2.4L SUCTION CONTROL VALVE. 294200-0360 294009-0260

I had intermittent power loss in my 2.4 on the last day of a 9-week trip a couple of years ago, it was due to a broken wire at the turbo actuator. The symptoms sound similar, would lose turbo boost thus very low on power, then would go into limp mode which could be reset by switching ignition off & back on (this does not always work to reset limp mode). If you can get someone to read the fault codes from the ECU it will help point you in the right direction.

Unfortunately when it was plugged into a diagnostic device the mechanic had it didn't show any fault.

After not started at all again yesterday, it did start again this morning albeit not straight up as normal and then wasn't running very well and any acceleration made it start missing.

Going to get a VCV and fuel filter and swap this week to see if that fixes it.
