i have test the fuel pump, normal : 33mV https://www.landyzone.co.uk/land-rover/check-td5-fuel-pump-hp.358086/ re swap MAP and MAF (450gr à 3000 when MAP bock à 200kpa) with new and from my engine (D2), no change. when i stop rev the engine i have a small step on the drop from 800rpm to 750rpm...

still limited to 0,8/0,9 bar maximum without ecu error. bad injector can produce this situation ?

new fuel filter yes, full service including all point and the lack of power is perfectly linear (like a limp mode or maf disconnect). no engine stall or rev variation, perfect start even after 10 days so no air in the line.

Hi, I have a friend at home with a low powered defender (2006 15p et ABS), 122.000km today (brand new ? :)) Power problem begin just after a full service after purchase, run well from Norway to france by highway but after the big service power problem start (all oil, all filter, injector seal...

thank you, i have some occupation for the winter with this problem ! for the abs : it's C0504-3 SLABS for speed signal, i think it's a old mod/tuning for speed ajustement on dashboard with non regular tire size.

ok with my multimer between fusebox and bcu other connector : ABS unit, a cutte wire here ?

I watch during the day. Below, a zoom of my C0573 connector and its current modification... it is indeed number 7 and not number 2 because I looked at the description of the connector the wrong way. Sorry, rookie mistake!

I installed a new starter and the engine started without problem. The old one hardly works anymore, in my last tests it was almost completely dead. I think I completed my original starter during my many starting attempts with the fuel problem and air cavitation in the pump. Only that doesn't...

When I installed the new BCU I had too weak a signal for the fob. Since I changed the receiving module on the roof, i have a better signal and I added the original remote control and a new one without problem to open/close all door. Now I have 100% success in the RF detection test with the...

ok, with this wire (pin 2 on C0573), i have recover the starter. and if i remove the glow plug relay, i have the error inside the ECU. it's a by pass for "crank enable" with a locked BCU, confirmed by a guy. for information, i have unpack my second BCU (in spare), read the eka, edit the EKA to...

no change with another battery (12,5v + booster) just installed rave

ok, I'm testing this evening after work with capacitor booster. I prefer it to be the fault of a too weak battery to end it, I could die of shame happily after that... I agree with you regarding the injector seals, I have not found a single testimony in several Land Rover forums of a sudden...

thank you for your help i have update the first post for better explanation !

First, i have air noise during pump initialisation cycle (like a dry pump, scream) when the first engine start failure : i have change filter, air bleed valve (new) and clean no return valve (small duck, a very little hole but clean) : less noise and 4 bar at regulator Just after, i have test a...

Hi PopPos, yes C573 ou C0573. I think C0573-2 but i'm not sure. Any idea for a UE TD5 ? No information for injector seal but, and yes it have happened very fast (on 4 days, after 10 or more start witouth problem, 500KM and the next day : 2 x failure to start at the first time, only the 3...

Hi ! I'm new here and i fall here from google with my key word "c0573". Are you aware of this modification ? my td5 don't start suddenly. https://www.landyzone.co.uk/land-rover/td5-no-start-and-c0573-fusebox-connector.388840/

Hi, sorry my english. All step during September/October 2023. I have a nanocom and AEG battery booster (+15A or boost +100A) First : this discovery have a bad IDM (water ingress on connector, turn signal problem and "B" blink on odometer) bad BCU : after a battery teardown, locked (hazard...
