Thread: TDCI fuel blockage?

I found that by reducing the fuel demand with the accelerator I could keep making rather stately progress into town. At one point the truck stumbled and died completely, but then restarted and ran normally for a couple of minutes before back to choking..

A classic intermittent fuel blockage. The car was just serviced last week, but the fuel filter was not replaced. Now I'm wondering, do I just need to swap out the filter or can TDCIs block elsewhere, such as in the fuel pump itself? Or might I have a faulty fuel pump? Anybody experienced something similar before? I'm pretty certain its a problem with fuel supply but don't know much about modern Common Rail Motors -so any previous experiences or advice welcomed.

Cheers

Has it all come good after the vehicle has had a bit of a rest? (As I understand it, the vehicle can reduce power output whenever it thinks it's in danger of overheating or damage)

My first thought was the VCV.
Have read of this thread for an explanation and then if your up for it use the search function to find out more.
2.4 Puma - Possible Injector Problem

We had a similar problem a while back; loss of power for no apparent reason, then all came good The first thing I did was install a new fuel filter, even though the old one wasn't that old. There was no water but a whole lot of flaky crud did come out when I drained and shook it out,




The fault has not come back ....................... yet.

This is one thread addressing the overheat or overwork possibility I mentioned. Have a read and see if it rings true for your (OP) situation.

Puma Power Loss

Land Rover improved engine to the CRD system but the diesel filter is still as simple as these from 200/300 tdi.... I personally added a secondary filter from Diesel Care, which position is just on the ladder frame chassis next to the gear box. Clean the system with injector cleaner every 5000 Kms. No problem at all. Strongly recommend the 3 micron secondary filter kit(which has a prime bleeding pump itself!), costs less than 400 but can avoid many potential issues.

If its like mine, be aware there are TWO fuel filters, one in the engine bay and the other down near the fuel tank, inside the driver's side rear wheel, behind a guard which unclips. The rear one is frequently overlooked, with disastrous consequences. They cost about $100 from a LR dealer and you can change them yourself. Remember to fill the new filter with fuel before screwing it into place, to avoid air in the system. I discovererd mine had never been replaced under the previous owner and after 70,000 kms it had actually rusted out and dumped fuel on the carport floor. There is a picture of it in the 'What Did You Do On Your Landy Today' thread. New filters are cheap insurance, in my book.

Out of curiosity how many kms are on your Puma now Mick?

The first filter is obviously located near rear right wheel covered by a shelter. But I never realize the second one which is in engine bay.... Is the second one need to change frequently? ( I never saw the second filter in the service kits either). My landy's first filter was also neglected by former owner, I just replaced it 1000kms ago with the stock one already full of some algae inside.
