Thread: Common rail diesel problems

The Puma engined Defender and indeed all of the other current diesel engined Land Rovers are common rail...it's the only way that a diesel engine can comply with the Euro strandards I guess.

One or two folks here have had big problems with water in fuel.

I noticed some exhorbitantly priced water filtration funnels at TJM the other day...probably good insurance for filling up from remote supplies.

Umm, the current Defender is a common rail Euro engine and the previous TD5 engine was a unit injector engine and could have the same issues if fuel quality and filtration wasn't up to scratch.

In fact when the TD5 was first released Land Rover Australia had quite a number of injector failures due to dirty Australian fuel, and at the time an injector was near enough to $2000 LRA's cost !

Common rail has taken over from unit injectors as it's a far cheaper system overall and achieves the same end.

Thank you, now what is the best way to insure ourselves from a similar incident? [btw. since I bought my d2, I have had to endure no amount of ribbing from my Japanese vehicle owning friends, some good natured, a rare few downright obnoxious, and it is with the utmost calm I say to the rare few.... KARMA! grasshoppers

My Td6 got bad fuel last time I drove back to NSW but a filter change had it going again and it hasn't missed a beat since.The D4D has had a long history of injector trouble but like all things tojo you never hear it from owners. Pat

I'm getting twin saddle tanks on my Puma with a seperate pump and water trap/filter so I can filter the fuel twice.Bad fuel is all too common. Pat

filters and water traps. A centrifugal filter for the fuel would be cool!

When my RRS was getting its roadworthy, the tester was selling a system - basically water trap and extra fine filter for common rail diesels. He suggested I buy and fit as he had seen a few common rails with issues due to water.

I declined but am certainly interested if the evidence indicates Aust fuel is an issue. It is a risk management thing.

simple enough.

in about 80% of the servos tested in australia the diesel failed to meet even the euro 3 spec for diesel failing on both suspended water and suspended particulate matter.

most servos were also over the acceptable limit for settled water in the underground tanks.


and naturally all the military diesel fuel that Ive had tested doesn't meet euro 3 standards (td5) hows the gwagen going to cope (euro 5 standard)
