It's more complicated that that(and than the rudimentary theory from aulro), the camshaft and rocker shaft are managing the flow through the injector in the fuel rail it has nothing to do with the injected quantity through the nozzle into the combustion chamber, that's 100% electronically...

Hi, TC doesnt put power on any wheel, in a nutshell: it's supposed to apply brake on the spinning wheel to engage the axle's diff and equalise the wheel speeds, largely explained in the WSM(attached)... it used to misbehave if the brake pads are unevenly worn, the wheels are more than 5% bigger...

means that your fuel delivery system is well sealed, i've seen many cases when Td5's are running rough with dead pump on residual pressure untill the pressure is released somewhere

If it's OBD2 scanner it can show false fault codes, you have to plug in a compatible tool(nanocom or hawkeye) for the real code and watch live sensor readings while the symptom occurs but usually white smoke is mostly mechanical not a management issue cos these can cause black smoke due to...

That's specific for automatic ECUs as the manual doesnt have a CAN circuit... tell me what part number is on the ECU cos i have the feeling that the PO fitted a botched up automatic ECU then this can be the problem....btw what diagnostic tool you have?

there is no speed limit regulated but better not drive it much in low cos you'll ruin the box hence the recommendation in the owner's manual... low has it's clear purpose, it was not conceived for long road driving, the TB, gearbox and engine can all overheat on a long run

The injectors are working with a quite high voltage PWM signal(between 110 - 163V) which is very sensitive to contact issues so cable tying a worn connector might not be good enough cos the cavities can be loose while they must be very tight to the pins. I don't know exactly what kind of plugs...

What's O2 Td5 and what float switch? ... as about the issue, first of all make sure there is enough battery power, eventually charge it well disconnected before you do anything else

Hi, some things to clarify: 1. just the ABS and TC lights no other? 2. is your D2 facelift or not? 3. can you see the HDC warning on self test after you turn ignition on? 4. do you have diff-lock?

40A... though all you have to do is to google out that p/n i gave you

It's only one fuel pump relay which can trigger that fault code: R103(C0730), p/n YWB000150..., R100 is the so called "main relay" not for fuel pump, if this fails the engine doest start at all, as you didnt say what year is your's i can just guess it's pre-2002

No i didnt, not my style... just mentioned things now and then depending on the subject of the discussion

This one https://www.turborebuild.co.uk/enhanced-turbo-land-rover-defender-discovery-td5-452239-hybrid-turbocharger-chra-cartridge ... with the other tunings i have the low end response is better than with the stock cartridge but not spectacular... just enough to please me cos i dont need...

You can fit the blade 90 degrees left/right according to your needs... i have one of these and i love it, worth it's weight in gold for fiddly jobs

dont you have an oscillating tool?

Mine was rebuilt with THIS by my trusted mechanic and fitted a hybrid cartridge and it's better and cheaper than new

I used red lens repair tape on mine then fitted STC50027 lamp guards and they look like new

No better diagram than that, the "extra pulley" at the top is the idler instead of the aircon compressor, this one https://www.island-4x4.co.uk/idler-less-britpart-err6493-p-27710.html, the other (nr.7) is instead of the ACE pump(ERR6949)... both are compulsory to fit the PQS101490 belt

you have to replace the injector loom ASAP http://www.discovery2.co.uk/Injector_harness.html, if you have a compatible scanner(not generic obd2) see live injector roughness, manifold pressure and inlet air temp readings

Is it automatic? Check the ECU red plug for oil. Unplug the MAF and see how it runs that way... the EGR is still in place?
