Do you mean the plugs to kept dirt out until you install them and refit the air lines?

Made a neat 22mm hole in the lower tailgate carpet panel so I can manually open it with my finger if the latch fails which I've heard they can do. 22mm because that was the size of a rubber plug I had lying around.

Thick ice on the car this morning at 6am, wasn't expecting that!
Bled the air out which took seconds and she fired right up bless her.

100% not the (bosch) plugs, it's 100% air ingress, I'm just not 100% sure it's the injector, only 99%. Cold start again tomorrow morning, I'll bleed the air out first before cranking and I'm sure it'll fire right up after 1 cycle of the plugs.

Only on the Thor, it has the engine ECU in it on a GEMS.

Another lesson learnt then.!
Mate turned up and even though there was no air in the clear fuel line this morning plenty of air appeared this afternoon whilst he cranked and I observed. Bled that out and she fired up fine. I've had an issue in the past with number one injector leaking around the head joint, a new copper washer fixed that for a bit then it started leaking again. On closer inspection there was a small burr on the injector sealing face, I dressed that off, another new copper washer and its been fine for nearly 12 months but is leaking again worse than ever, tested by spraying a bit of wd40 into the well that the injector sits in. Also have a slight leak from a spill pipe nipple, not the rubber spill pipe itself but from the nipple on the injector. That will be the air ingress problem I strongly suspect.
Used good injector I'm after now. Bmw m51 engine, few on ebay but I'm waiting on a reply from a breaker I trust who usually comes up trumps.
Ordered a second hand injector

The problem I'm having at the moment is there is no available helper (my wife) to work the ignition switch while I mess about under the bonnet so I didn't get to try a cold start until this morning, 2 days later. I suspected air in the fuel line, LR helpfully fit a clear line between the filter and the injector pump. Any air showing gives me something to work on but it was full of fuel and stayed full of fuel while cranking, no sign of firing. Had to then take the wife to work in the defender so no helper again until friday!
A super busy mate might be able to swing by today for 1/2 hr so ill check glow plug and stop solenoid operation. Bit green on leccy stuff, have nanocom so ill plug that in and stare confusingly at the screen as normal for me. No panicking yet as I have the 110 200tdi which is a super starter.
A search shows a fuse and relay in the engine ecu box for the glows so I might look at them whilst waiting for my mate, it's an empty box behind the battery on petrols.

Oops, forgot the space after the quote.
And...fixed the quote lol!.

I’m not a diesel guy but if it started instantly I wouldn’t have suspected glow plugs.

Nor me but if I didn't mention the new plugs someone will have suggested fitting new ones so I was just saving replies.
I've had issues with diesel leaks around the injector washer last year and it was the same symptoms so that was my first port of call but no, all fine. Update tomorrow maybe.

Well, it wasn't spill pipes, can't see anything wrong visually. Recent new glowplugs (bosch), I'll see how she is on a cold start tomorrow.

2001 dhse, started instantly this morning which is usual but then died after 2 seconds.
Suspect a leaky spill pipe letting air in. I'll have a looksee after lunch.

After stripping the door cards and sub woofer I found the reasons for the poor sound system. Both rear sub speakers were dust but they repaired easily with a new suspension kit off ebay, they now work. All 4 mid range were dust too so fitted new ones and the 2 rear door bass speakers were seized solid. Fitted the 2 good bass speakers from the front doors into the rear doors and got 2 new bass speakers for the front doors.
Even fiddled with the CD player under the sub woofer and got that going again but I don't know how exactly! So every thing is working correctly again, very happy.

Spot on. I replaced a right hand rear when it was left hand front until I found the nanocom issue. I've put a label on the nano box to remind me.

OK , a search has revealed its the sub woofer amp.
So marty...looks like I don't need a dsp amp so that's available again.
Going to order 2 new sub woofer speakers and test it out, see what happens. If the 2nd row speakers still don't work but the sub woofer ones do, then ...I'll be back pestering the forum!

The cables from this small box go to the sub woofer speakers.. what is this small box and what does it do?

And yes, if it is not a DSP (Digital Signal Processing) amp, you only get the front speakers.
So, if you do find the black box up top behind the sound insulation behind the subwoofer box, post the part number.
I had the dead DSP amp issue,(twice!) and did the disco amp thing on my 02 then started collecting any
DSP amps I came across in wreckers yards. Now, I think I have 3 spares! Worth having for the great sound!

Love this forum! So much knowledge !
Looks like I'll need martys dsp amp then.
Richard...what route are you taking to martys? You possibly might be passing within a reasonable distance of me(telford, shropshire) . 2 spare bedrooms here and parking if you want a stop over? Or could meet up at a services to save marty packing and posting stuff to me?

Have a look first and see if there is a DSP amp in there...
A DHSE model, I wouldn't have thought would have the DSP amp - as it was mostly on the Vogue spec with sat nav. But who knows - at the end of the production years, it seems LR made a mish mash of vehicles and specs with what they had lying around...

Another way to check is to pop the head unit out and see what wiring is in there... If it has DSP amp, then there will only be a Left/Right audio feed out (4 wires - from memory Red and Yellow twisted pairs - one solid colour and one with a black tracer)- if it's got door amps, then you'll have Front Left/Right, and Rear Left/Right - so 8 wires and Red/Yellow/Blue/Green twisted pairs - again one solid colour and one with a black tracer).

Don't want to sell you a DSP amp if you don't need one!

I'll have a look for the head unit and test a few bits over the weekend. I'll also look and see what speakers I have here, as I know I had some of the door woofers as one point and maybe a few of the mids aswell - but I can't remember what I kept and what I chucked out.

Marty

Wish I had popped the radio out first! No amp found anywhere but I did find a black box, no markings that has been tiger sealed in the bottom of the well..tracker maybe?
Popped out the radio and there is a toffee coloured plug with 8 wires which match your quoted colours so door amps I have!
Subwoofer has 2 speakers and a small box mounted on the forward top edge with 9 wires on a multiple.
Subwoofer has e26640 and xqa100010 numbers.
Small box has e26640 and 99-a4038-xxx and
1280.988/3894.
8 black/white wires and a thicker red wire.
Next move ? Oh..this small box connects to the main loom and also disappears into the subwoofer box.

Thanks Richard and marty, weather is looking better for tomorrow so I'll have more info for then. Although I've had all 4 door cards off to waxoil and the 2 fronts off again to do the stiff sticky out door handle repairs I don't or can't remember if there were door amps. Popping the radio out is a top tip.

Never got a chance to strip anything, bloody rain is relentless! Looking slightly better tomorrow, Saturday, I'll note any part numbers I find. Will need advice on what speakers I need to replace the wrecked sub woofer ones too at some point. I have read somewhere of someone repairing them but can't find it now but unless they are very expensive I'll replace them.

Pressing the tone button brings up bass, treble, balance and sub woofers no dsp.
Going to strip out all the stuff on the subwoofer side and see what I've got.

That's interesting to know, shall fiddle with it maybe tomorrow. Ta.
