2016 Discovery 4 3.0 SDV6 Graphite LE Auto Loire Blue

I agree with Barn1e and I think others have advised similarly. Take the car back and ask for a full refund. You were sold a potentially dangerous car without the required safety equipment it is supposed to have.

I'd be worried about what other hidden problems and bodies might be there.

I know you've invested a lot of time and effort investigating the issues but there are better, well cared for examples out there.

It all depends on your ability and interest, time, money and workshop facilities available, overall condition of vehicle, what you paid for it, what the vehicle was sold as, etc,etc, only you can make that decision.
If the car is otherwise alround good, you bought it cheap I would enjoy the challenge and it would give me great satisfaction getting it repaired and back on the road, but if you paid average price for it, you don't have the spare time, ability, facilities, cash and you can get your money back I would do that. What is the point in going to all the work and effort if you are not saving money? It can when others can't,
It will when others won't,
It goes where others don't.

Thing is he has haggled to get £1000 pound of the asking price because of the fault if that is all it takes to repair it that could make the car a bit of a bargain to him so would thre be any need to reject it

Air bags including the curtain airbag are comparatively easy to change, if you can drop one side of the roof lining down 6" you should have enough room to change it.

You cant fit a module off another vehicle without it being reset to factory spec. but airbags you can provided they have not been fired, I use the term fired as that's what they are - a loaded gun, the seat belt pretensioners simply have a blank bullet in them, so for a specialist to recharge them they simply change the blank bullet, similar to what is used a Hilti gun or even a starting pistol, could be 0.22 blank. They are prrfectly safe providing common sense and elementary precautions are taken and there is no reason why you can't replace them.

Are you sure about that the blanks to fire seat belt pre tensioner. I have not done D3 or D4 but many others I have and have not seen any fired by blanks. Normally spring gas cylinder or even cable in some cars. Air bag are triggered by electric but normally use a chemical based on an acidic compound hence why you often get burns after they had triggered. MY17 D5 1st Edition Namib Orange

thks for the info and am taking it in and am very grateful

i've taken a lot of time in removing panels from both sides , no damage seen, nor any spray , loose bolts anywhere to be found

i did do a full pre car check before i bought it and there was nothing, it even a report of an accident, also done a full hpi check all clear so felt confident that nothing had happened to it, how wrong i was, lol

check all the belts on all 7 x seats all pull out fully and return on there own

i think what has happened , as the drivers door trim is off is hasn't been t boned otherwise i would have seen damage on the b post , as there's an impact sensor at the bottom of the b post , i think it's been side swiped causing the right hand side airbags to go off , both pretensioners have fired

they've then replaced the drivers pre tensioner only and the steering wheel airbag , i should have looked at the date when i fitted the cruise module , might quickly whip the steering wheel airbag off again to see the date

the mot is july 2017 so in theory is was ok before that date due to it being a mot failure

i will know more after weds as it's going for a full inspection , he's also a mot examiner and will go over the car with a fine tooth comb as i want to know for peace of mind , but more importantly for other road users , i need to be 101% sure it is sound and fit to be on the road, of course i know ref the srs light but mechanically has to be spot on

thks again

thks so much for the replies and i really am grateful to such honest replies as to be honest that's what i wanted

well i paid 3.5 k for it , my late wife left me some money as she knew i always wanted a disco , alas i felt in owning landies for 30 x years i knew i had enough knowledge , of course i feel i've come unstuck , relying a little bit on a car pre check so u know it hasn't been stolen or a dodgy background , yet again that hasn't been the case

when i saw it i knew it needed some work, restored a few series landies in the past , happy to get stuck in and do things on them

but at the end of the day didn't realise ref the airbags, it wouldn't have been so bad if they was there and faulty , easier to get reconditioned

the compressor needs rebuilding , air con recharging and cam belts done as i don't know if they've been changed

it's sound, has the surface rust on the chassis which in the spring with treat the whole thing, have a messed up back with pins and screws but doesn't hold me back, only the lifting part and have my son who loves landies and will always help me

i could take it back and reject it and this may sound mad but like a challenge , but of course not madness when a car u know is a money pit , after weds full inspection i will know a lot more, it its sounds and needs the airbags , compressor rebuild a few brake pasts discs etc i'm fine with that

i do though felt s bit of a pain in keep asking questions which inimagine have been done to death

i really can't begin to start saying thks to everyone for such fantastic help , will report back after weds

if it's a complete dog i will reject it, but need to see what facts are put before me first as i hope there nothing else major wrong but weds will be fix or

rid of it

i really do enjoy working on landies and fixing them, but i know for example there's no point polishing. a car if the chassis is rotten

i've taken a lot of notice what u guys have said because of the massive knowledge u have with these , regardless i'm middle aged i take notice of what others are saying , i never ignore sound advice

thks also about the headlining , is a shame i could slide it out the back, but great idea in resting it on the seats , wasn't sure how far i could get the thing out

will post some pics as i go along, maybe helping others , so if someone else came on with a srs light we all know what the possibilities and faults can be

lastly to everyone

Right side curtain airbag is behind the roof lining, which it looks like you have 2 codes for, it's also possible Ecu has had more than 5 resets which men's it will need replacing. Present

Fingers crossed for a positive report on Wednesday.

It's a great forum isn't it. Friendly, supportive and knowledgeable with humour added in too.

General electrical failure on drivers side curtain airbag which is behind roof lining, sensor is in b puller, wiring for curtain bag is normally from the rear,Ecu could possibly need replacing if air bags have been deployed and reset more than 5 times, tacking it to a garage for a plug in is pointless unless they have a tool that will speak directly to the ecu.

read the iid it will reset the ecm back to its normal state

however as u say if it can only do it 5x times the iid may not be able to to it

am trying to work out there's 3 air bags down the sides or is it two

been trying to search for part numbers

as there's nothing there plugged in assume it's therefore one big open circuit , acting like one loop with a big gap in the middle

as it says side and curtain , will order the two curtain ones then drop the headlining and fit them ,

reminds me i must buy some gloves so i don't mark the headlining

will be like the films, so i cut the red or blue wire scenario in handling the air bag canisters , good job i don't have a heart condition but may do after handling them

Somthing is not right here.
No HPI record
No sign of any damage even when trim panels remove
No sign of over spray even with panels removed.
No seat air bag deployment
Only fault code appeas to be drivers side curtain air bag which is missing.
No damage to headlining even though we are sumisung the side air bag has gone off.

If it had been in accident some signs would be evident especially after stripping trim panels off.
The head lining would dhow signs of damage if the curtain air bag had deployed.
If it had and they had replaced the head lining why not replace curtain air bag before fitting headlining.
If the car had sustained a side impact to trigger the curtain air bag then the seat airbag would have triggered as well. MY17 D5 1st Edition Namib Orange

this , i did wonder where the connection started from , will be more clear i assume once i drop that liner

the iid says it will reset the ecm back to its normal state , but like u say may be out of luck due to the reset limit on the ecm

as a side note shame i couldnt get the ecm history data , believe it's only land rover that can retrieve it

the garage is going to check the entire car mechanically for me and also is going to change all the oils and filters , so i personally know a starting point for the service schedule

also mainly to tell me if to keep the car or reject it

The curtain air bag is one unit runs full length of the roof but some times have 2 stage deployment that's possibly why you have 2 codes,if you say airbag is missing there should be a yellow connecter somewhere along the roof gussets above drivers rear door backwards. Present

yes on seeing the light i thought it was a good haggling point , i was prepared to walk away as i knew there are plenty out there and seen others before hand that were high mileage

this only has 98,000 miles so also said i've got to spend out on getting the cam belts done

plus reminds me i'm waiting to hear back from the manager tues ,

why is it always agro getting another car
