TD 6 major problem
Discussion
Bit of advice please....
Have a TD6 on 52 plate; recently had the fuel pump lock up and snap chain subsequently snapping camshaft in 5 places. I have replaced all injectors, recon pump, filters, camshafts and recon head at great expence.
Picked up the vehicle and drove 180 miles only to have the injector warning light come on again. Car was recovered back to garage.
Mechanic tells me that the recon pump had locked again but no further damage. I have money back on pump and am buying a new one. But mechanic is talking about replacing the fuel tank as he thinks there maybe corrosion, debris in tank. I think this is excessive as filter should prevent anything hitting the pump and if the tank was correctly cleaned out any water or petrol, dirty diesel that may have been in there should have been removed. General opinion is that it was probably the recom pump that was faulty (they have given the money back on this).
Any comments appreciated.

Since I have no experience dealing with the diesels firsthand I have read alot of information on them from LR and the entire design itself.
The fuel pump runs the timing belt. It also acts as the timing mechanism. And as you have seen the when the pump failed it took everything else.
LR produced a bulletin that stated if a customer puts Diesel its a complete disaster if started up.
What they want you to do is replace every single line and pump and tanks.
Do not clean the pump. The reason being is that the seals dry out and the diesel itself is a lubricating mechanism.
I suspect either the gas was installed into the tank or the fuel was contaminated by Gas in the fuel stations tanks.
Can you give me more information.
I supsect the Mechanic seriously underdiagnosed the system causing the problem. Unfortunately they are very delicate systems the Diesel is. Actually the gas isnt any better. It just wont run with less then premium.

Any contamination on the system will kill the pump no matter how many pumps you install. Either all the lines and pump and tanks or keep repeating the process.
the first part of the diagnosis should have been a fuel sample taken directly from the tank itself. Not try to get the motor running.
The pump shouldnt be warranteed because the source of the problem wasntfound. He threw parts at the problem and didnt get to the root of it.
Sorry but this is the most expensive fix on a Diesel Land Rover. the Mechanic should have known that and did his homework.
Was this done at a dealership or not?

having worked at a main dealer for some years the only time i have come accross this problem is when a gentleman filled his td6 up with unleaded and drove it untill it stopped, his too siezed the pump snapped the chain and cvaused major engine damag, resulting in a rather hefty bill for a new engine.
120A,
I wasn't driving the vehicle the first time the problem happened. But most certainly, having picked it up from the garage after the major repairs, I filled it with Shell diesel and drove 190 miles before the injector warning light came on. Perhaps there could have been residue in the tank if the fuel was incorrect the first time and the tank not cleaned; although I do not necessarily think that is the case here. The mechanic has never mentioned any issues with fuel nor did the driver at the time.
Plus I had two injectors go last year that were replaced under warranty. The vehicle was not used for approx 5 months very soon after this work was done. It was run for 2 months following(with no issues) and then these problems began (out of warranty of course !!). The terrible service I received from the main dealer is another story
I am begining to suspect the problem occuring the second time may be down to a badly reconditioned fuel pump.

sorry but it has to be said, what a plonker!!!!!(not you the customer who filled it up with petrol)
120a,
Yeah it's a strange one I must admit. I had previous issues with the injectors as mentioned but the vehicle was running perfectly prior to two requiring replacement last year - it had just completed 3,500 miles around Europe without an issue.
A friend was driving when the fuel pump let-go and all the rest followed suit (great design that there is not break to prevent camshafts etc snapping in the event of a siezure of the pump). First thing I enquired was re the fuel and he swears that it was diesel. The bill would have been much more but I am only paying for the parts and small labour cost. Apparently the dealer was quoting something along the lines of £15k to do the job.
My intial question was if I really needed to replace the fuel tank. Everything elase has been replaced. I am getting conflicting reports from different dealers. I am obviously trying to keep the cost down but can not afford to have the problem reoccur again. Personally I suspect the reconditioned pump was at fault the latest time. I have ordered a new one from dealer.
Your thoughts would be appreciated.

im not saying you have put the wrong fuel in just that this is the only time i have heard of that problem being caused by anything other than incorrect fuel. we have at least 3 wrong fuels a week, to repair a td6 that has been run on unleaded the bill comes to just short of £6k
just curious, what are the common problems with the 4.4 V8?, im hoping to buy one early next year.
nothing really with engine apart from the oil filter housings break off the mounts if not un done with care. just few suspension problems but usually nothing expensive also the diff problems but again most have had modified prop and diff fitted by now. if you can when it comes to pads/discs change do them yourself as it can be very expensive from a dealer. just make sure you get one that has been serviced regularly and you should be ok. they are a general all round good car, good on fuel if driven gently but go like a scalded cat when floored, always puts a smile on my face driving them even compared to the new super charged model

after driving my brothers TD6 i know that just isnt an option, no offence to other owners but i found it particularly noisy and rather sluggish- i think even the 2.5 engine in the P38 was quieter, i plan to get a V8 and LPG convert it as i think thier wonderful cars and might even do a little off roading in it too, i would have thought the supercharged version is noticably faster than the BMW 4.4 unit? well it is on paper but having never driven either i cant really say.

having extensively driven both, yes the supercharged is a lot faster, there hard to believe really. when driving one you sit there thinking 'how can something this big go this bloody fast'
the only RRs ive driven extensivly are the 4.6 P38 and the TD6, to tell the truth i didnt think there was a great deal of difference in performance between the 2 but the modern V8s and especially the supercharged version i can well imagine can shift.
