Yes, RAVE mentions removing both the cylinder head gasket, and the sump gasket in order to change the chain. Also specifies removing the crankshaft pulley. Looks like a full on job!

You may need to put it on a computer to re-sync with the ECU, but first check your connections, disconnect the battery for a few mins and then try reconnecting.

This is the Automatic Gearbox Temp alert. Do not drive with it on! Get your oil and gearbox looked at urgently!

if it's sluggish and bucking and there may or may not be a check engine light on, it's probably in need of spark plugs, wires, and / or ignition coil packs. also if it overheated, it may have blown the a head gasket or two. at least take it to a good land rover dealer and have a multi point inspection done. ive worked on a lot of discos where theyve needed a water pump, head gaskets, throttle heater and gasket, new coolant lines, front main seal, just for starters.... most just get a complete engine reseal where we take the entire engine out and put all new gaskets in it. at least a $2,000 job for the customer. it may be time to look for a good deal on it as a trade in.

BAD spark! check plugs wires and coil packs. the wires are a real pain to replace because of the location of the coil packs between the intake manifold and firewall.

Check to see if your alt. is charging or you have a blown fuse to the alt.

We recommend Replacement.

Hope this tip helps

for some reason the four wheel drive is trying to engage while driving. why i dont know.

the cage bearings in the input and output shaft in the transfer case are weak and letting slack into the gear to gear drive also slack in the chain itself the tranfer case just needs to be serviced/rebuilt

Mine just started doing the same thing. the book says that the electronic transmission controler is in fault mode. I haven't found anything else out yet

This system uses 4 speed sensors to measure the individual wheel speeds and detect slip, if u are just driving along at a steady speed and these lights come on then u have a problem, if they come on while accelerating or in 4 wheel drive then u may not have a problem, in order to test the system for faults the dealer will need to test the ABS system for fault codes, all the systems u mentioned are controlled by and an off shoot of the active ABS system, an active ABS is able to apply brakes without any input from the driver, that allows it to to do the Traction control and other traction control related functions like downhill descent control, so if the answer to the questions is that the lights come on at normal cruise then yes you have a malfunction in the system, the most common fault is one of the 4 wheel speed sensors has a corrupted signal due to dirt or metal particles clinging to it, it is a magnetic type sensor.

check your coolant level and top off if needed. its probably time for a new thermostat as well. make sure you get one from land rover when you do this and the proper mix of coolant and distilled water depending on where you live. cheers.

Yes, if you can get the oil pan off.

I think u may have a injection pump problem, have it checked for proper pressure.

check the choke and the timing

P1413 Secondary Air Injection Pump Relay Control Circuit Signal Low

P1415 Secondary Air Injection (AIR) System Bank 1

You have a smog problem.

Could be MAFS out of range - check & replace if needed.

Or maybe the EGR valve is stuck open, sometimes you can clean them out but most of the time a new one is required.

Both common on the TD5

there is a spray glue that can be used to repair ur headliner most craft stores and automotive stores carry it
