Thank you all for the tips and the links. Today I worked on my Turn indicator lights. I connected the purple supply terminal to the left and right indicator terminals and as described the left or right indicator lights stayed on without flashing. I tried to connect purple terminal to white with green trace flasher terminal and nothing happened. Am I supposed to attach purple terminal to left or right terminals at the same time as the purple to flasher terminal? Can I rule out hazard switch as being defective? Thanks everyone.

Hello. My TD5 which drowned last year was up and running after I finally replaced my ECU a second time. I have been using it for about 9 months now. Last month the turn lights and the the hazard lights went out. After a couple of days the hazard light came on for a few seconds then died out again. It's been a month since. I read somewhere that the hazard lights are connected to a relay. If so, it might be the relay but I can't seem to find it's location. Of course it could also be the hazard switch. But because of my car's flooding it could be grounded wires. Can anyone offer a suggestion which repair I should try first? Thanks, Tony

This was a very interesting read. So glad that you got your td5 running. I was struggling with my td5 last year also ever since it went under up to the roof for 12 hours in the big flood in Manila. I tried everything until I finally found out that the used ECU I ordered on ebay was defective and all it needed was a brand new ECU I bought from Singapore. I also sought help from Porny but he wasn't online around that time. Cheers!

Thanks for the replies and the link guys. Yes, I have a 2004 Defender TD5. Will try to get in touch with Porny.

Hello. My TD5 which drowned in the flood last September is running smoothly after I installed a brand new ECU. However, when I try to accelerate pass 120 kph the engine will refuse to go faster beyond this speed. I was wondering if there are some ECUs that have speed limiters on them. The engine will run smoothly until 119 kph and will sort of stall at 120 kph. If it is the case that there is a speed limiter can this be reprogrammed to disable the speed limiter. Also, the computer reported some faults. It says that there is partial grounding in Injectors 1,2,4,5. The engine will start with one-click and will run smoothly. I have no reason to believe that the injectors are malfunctioning aside from the fact that the engine will stall consistently at 120 kph. Also, as far as I know my radiator fan is belt driven but there is a section in the Vehicle Explorer 1.26 that says that TD5 radiator fan is enabled. Could it be that the ECU I got is meant for a Disco? Another issue I have is that my engine temp gauge will read at less than 1/2 upon starting the engine in the morning and as the engine heats-up the gauge will go all the way to the left reading cold. I don't believe the terminals could have inverted themselves. I haven't changed my temp gauge and so it could be defective from the flood. Thank you once again for any input.

Thank you to everyone for all the help and advise during my defenders' darkest hours. TD5 up and running and yesterday the shop informed me that my PUMA fired up after they cleaned all contacts. Water really dulls the electrical connections. It took 4 months but now its time to bring the Defenders up to speed. :lol:

Thanks for the "words of encouragement" guys Time to roll-up the sleeves.

Hi. It;s not the fuse. I just checked now and the gauges were working again. Is there any reason both gauges will not work at the same time?

Hello, my TD5 was flooded last September. After replacing ECU and 10AS module the engine would start intermittently. After checking and cleaning ECU connector I was finally able to get the engine to run continuously, however, I noticed today that both my fuel gauge and speedometer have stopped working. They were fine yesterday and today they're dead. I'm sure they are faulty after being flooded but I was wondering why both at the same time and if they are connected to the ECU also and if its possible that one of the connectors may be loose failing to send a signal to gauges.Or if there is another area I should check for a loose connection. Thanks.

Hi Matt, Thanks for the tip about the connector leads. Although I haven't gotten my puma to start I was able to get my TD5 to start. I went to my TD5's ECU connector and folded a small piece of fine sandpaper and inserted it into each connector. Although I couldn't really sand thoroughly I was able to get the insides sanded a bit. I then crimped ever so slightly each connector and made sure they were all fully extended before inserting the connector. Did this to both the red and black ECU connectors. Started the engine and it fire! Test drove it around and it didn't falter. Will continue to drive it today. Keeping my fingers crossed. Hopefully I won't need the new ECU I ordered. I'll have a spare one then,

Thanks for the advise Matt, I have the same problem on my TD5. There is a loose connection that prevents the fuel pump and glow plug from getting current sometimes and that may be the problem. I ordered a new ECU but I'm also afraid that the pins in the connector might be the problem. I haven't figured out how to expose the pins but I'll give it a try today.

Just spoke to service guy. There is white smoke when cranking the engine but the problem is the current reaching the injectors is intermittent. They applied a tester to the connector leading to the injectors and found that the current is not constant leading them to believe that there there must be corrosion deep in the wire harness of a loose wire. They still have to check the wires one by one.

Hi Matt, I was just quoting the service guy. I was wondering about that too. He also did mention there was white smoke. I'll have to have a talk with him this morning. I'll update you later. Thanks for the help. Tony

Hi, sorry to say but still no luck firing-up my puma. According to service they checked all engine sensors and all are fine except for a faulty crank position sensor. They swapped a crank position sensor from their demo unit but still could not get a pulse from the injectors. They would've brought down dash to check all wires one by one and all relays and fuses. Will update.

Hi, just an update. They took out ECU, instrument pack and security module of demo unit to swap onto my puma, engine still did not start. As a thought (in order to check they're ECU programming of my ECU) they decided to swap my set onto the demo unit and the demo unit started. (good news) I guess this means that my ECU even after being submerged for 12 hours most likely did not get damaged. They say the problem may be in the crank sensor. According to them they have coordinated with LR tech support in the UK but it seems the UK is confused as to how to diagnose the problem. DO you guys think that I should try swapping all 4 injectors?
