D4 - Are they worth the risk?

Very keen to buy a D4. I've found a decent 70k mile HSE and all seems good but nagging at the back of my mind is the whole crankshaft issue. Is it worth playing Russian roulette with £15 grand or is the whole problem overblown?

Would be grateful for real world advice

No mention of 7 seats here lad
 
I wish I could find that thread i found yesterday with the video on the business about changing the oil and how JLR know that the DPF regeneration biz is what leads to the oil dlution and the probs we all have heard about.
@gstuart is the guy for D3/D4s and he was on that thread.

Real world? On here? Latish on a Saturday night?

Only joking!

(We are usually serious in this part of the forum.)

Sorry and all that, I'll shut up now and finish my brandy!! 🤣 🤣 🤣 ,

Bloke I knew once got the sack from a job he had driving one in California, for tourists.
Pre-select gearbox. He got out of it clumsily and must have accidentally stood on the gear change pedal. He watched it driving itself off down the road.🤣🤣🤣


Don't know how the story finished, maybe he ran after it...🤣🤣

Hi buddy @Stanleysteamer

Is this the video ur thinking of plse, also a link ref fuel dilution


 
Once read an owner of a D4 say, it was like driving around on a hand grenade with the pin pulled!
People say the D3 is as crap, and yet I have been driving mine daily for the best part of ten years.
5k oil changes are essential.

Hi mate

Indeed from what I’ve also read over the last 8 x years of D3 ownership the D4’s seem to have more issues ref crank failures , etc over a D3 and the fuel dilution issue keeps coming up

Plus 1 to the 5k oil changes and wouldn’t ever buy a D4 without an extensive warranty along with a pot of at least 6k to cover things like, brakes, suspension and wishbone bushes as it seems every time someone buys a D3/4 these need doing as a matter of course

Hope ur keeping well my friend

I ought to tell you that my new neighbour in France, the biggest LR nut I know, has just taken on his son's D3 which has blown its engine.
He is talking about replacing it with a TD5.


I did say he was a nut!
 
Yep mate! Them's the ones!
Howz you doin?

Ur so welcome my friend , seems as more time passes by more solutions / answers are coming up with regards to D3/4 , alas from reports and reviews the D4’s seem to suffer more

Yeh not to bad’ish , looking forward to the spring time with warmer weather and brighter evenings , hope ur also keeping well

Indeed a TD5 would be one hell of a project seeing the D3’s canbus will be different , saying that have seen a bmw M57 engine being fitted into a D3

Simpler conversion is an engine from a S type jag then swapping over all the modules and ancillaries etc

Shame about them I have another mate who bought one off a bloke who had done business miles in it. He loves it but thinks he may have made a booboo buying ot so he's rather scared to drive it. TBH I don't know if its a D3 or a D4.
He needs to get on here and read up!

We're reasonably well here, just got our visas! time flies don't it?

Does seem that way but I’ve considered it that we only hear of the D3/4 engine failures in a collective manner on a forum , where we see multiple posts about the engine problems

Indeed also seem nay posts of the TDV6 covering well in excess of 200,000 miles+

Also from what I’ve read the uk D3 didn’t have DPF fitted whereas the European models did and therefore having issues

Apologises as didn’t see ur other posts ref visas , are u off to another country then plse, seems the older I get the more time goes quicker as the days roll by

I mostly natter on the "I would just like to say" thread. There they know that we spend 6 months nearly in our place in France every year and for that we need long stay visas. Forgot you don't go there much.

I'm not sure when they came in I thought it might be 2009 but I may well be wrong.
It would be interesting to see stats covering whether the V6s started blowing cranks when the DPFs came in or not.
does yours have one?
 
I also think I may be confusing DPFs with the need for "adblue" which I think came in quite a bit later.

So glad our cars are too old for all this! Although we can only drive one of them in central Toulouse.
 
DPF & SCR are two separate systems, the SCR is always downstream of the DPF but uses the additional heat from a DPF regen (passive or active) to 'cleanse' itself. SCR is EU6 mandated, DPF was introduced on some EU4 variants and all EU5 emission compliant systems. The vast majority of vehicles have no problems at all, it's only really when diesel is the wrong choice of engine for the useage case when problems occur.
