Thread: Engine Failure

Probably could have worded that a bit better , As the early designed pumps were a bit lite in structural strength in the area where the new tensioner is bolted to when changing the timing belt and most of the failures occurred after the timing belt change usually within 20000ks . This is a bad design fault and could not have been a known fault until it became one , the reasons i gave were conjecture by people on uk landrover forum sites as to what and when most of the failures occurred and as a result LR designed the new pump which beefed up the weak area of concern on the original pumps .
It was rare for a pump to fail before this time . Google Disko3 UK where you can find a lot of info . Rgds

its been the elephant in the room for a while now. DISCO3.CO.UK - View topic - Cam belt tensioner mount failure survey
Disco 3s came out in 2005 and given that the majority of housings failed shortly after the belts were changed at approx 166,000 km then they have been failing from as early as 2008 I would guess. Many of these were within warranty, so yes Landrover has been well aware of the issue.

Why havent they corrected them under a recall or amended service advisories? I guess because they dont have to. Manufacturers only perform recall repairs when they are forced to due to safety risks. this isnt a safety risk as far as they are concerned, no more so than crank failures, etc.

And as others will advise here on this thread, some apparently specialist land rover mechanics wont alert the car owner either. Best thing to do is stay tuned on this website and the Disco3.co.uk website and familiarise yourself with the known issues.

Good advice vee8auto. Having been a mechanic myself, now retired it's a minefield out there where technical information is concerned and the access and sharing of it via technical bulletins from dealerships. I think these websites are a great idea for owners and enthusiasts alike and its how I found them, by researching the answers to particular issues I had via the net. So, like you say, stay tuned to the site on a regular basis, where knowledge can be shared for current problems and those that might come about somewhere up ahead.

Does anyone know if this weakness has been corrected on the D4 ?


Not that I am upto 180K, but would be interesting to know.

Yes from MY09 onwards it is Ok I believe. Not sure if 3.0 litre has same part.

Yes all from 09 build are ok. And 3.0 has same pump

There was a change to Oz law in Jan 2011 that embodied the concept of consumer expectation. (Google "Broken but out of warranty ABC" as a starting point). In essence it states that if you fork out serious coin for a piece of kit that you expect to last for a long time then whether or not the item is still under warranty and it fails, you have recourse to the supplier/manufacturer. I used it to my advantage when i bought a $1500 oven in Perth and the digital display failed about 6 months out of warranty. I became aware of the above law change partway thru my protracted negotiations with the supplier and when i quoted the law to them, low and behold i had a new $600 digital display within two days at no cost to me. Not sure if there is a vehicle ombudsman in Oz but you might find that a statutory authority might give you some support. Having said that maybe nine years old is possibly stretching it!!!

I had a similar experience with an induction cooktop that was about a month or so out of warranty. Initially, they tried so sell me the part (about 1/2 cost of what we paid for stove), then realised no stock readily available, then tried to sell me a new one at huge discount. I just kept saying no. Why would I buy an appliance for $1000s to only last 2 years. Any reasonable buy would expect a $3000 stove to last a lot longer than 2 years. It's not of merchantable quality if that's all it lasts. They eventually installed the latest model at no cost.
