1. "Suspension Fault Max speed 30MPH"

   So coming back from Kgalagadi on Thursday the Disco started giving a suspension fault when switching on the Radio or A/C. A engine Restart would clear the fault till switching one of them on. Stopped at a battery shop and got a new battery. It kept on doing the same so gave the battery back, Eventually just kept on driving to Vryburg with no A/C or Radio. Friday morning started it up and it did absolutely nothing till about halfway to Pretoria where it gave a suspension fault max speed 30MPH. Switched off Radio and restared car and it didn't do it again. When we got home I started playing with the air suspension, it rises and lowers as normal and I can go from access to off-road height 3 times before it gives an suspension raising slowly warning, but no suspension fault. Drove with it today (A/C lights and radio on to draw some current) and only once gave me the warning where after i switched it off and started it again and warning was gone. It then gave me an engine systems fault and reduced power for 5 seconds or so which went away by itself. I then decided to turn around and go back home, 2km later engine systems fault which won't go away, I then got the launch fault code reader and read fault codes, it gave me cylinder 3 injector out of range and cylinder 5 timing out of range as well as a lost communication with can bus, first time I've seen those faults. I cleared them and drove home without incident.

   So my first guess was a dead battery/alternator
   Alternator charges at 14.4V at idle. battery has been tested and said Good battery but i don't trust those testers.
   The fault code reader i have can't read suspension faults it can only do engine/gearbox/abs.

   I'm more concerned about the suspension fault since the disco is now sitting about 20mm lower on the driver side which it never did.
   and the engine systems fault was most probably because it lost communication with can bus.

   Does someone around the Montana area perhaps have a faultmate or hawkeye which i can borrow to read the suspension faults.

   Any one else had a similar fault? How did you solve it?

   Any advice will be appreciated.

   I had similar symptoms, also started in the Kalaghadi at Xmas. It was worse for me in that I couldn't engage any gears so I had to have the vehicle trucked back to Centurion, very expensive. When it arrived back it was fine no problems, but i took it to Walter anyway to have it checked out, he found nothing wrong. About two weeks later I was driving and it started to rain, so i turned on the wipers, it went into limp mode and the suspension lowered. I did a lot of searching on the internet and found three guys who had had similar experiences, not exactly the same but close. All three found that the problem was associated with the windscreen wiper system, one had a duff relay and the other two faulty motors, they were replaced and the problem disappeared. I checked my relays but found nothing wrong, so I took a chance and fitted a new wiper motor, problem solved had no issues since then. None of the fault messages mentioned the wipers at all, I had suspension fault, transmission fault and HDC fault messages. The can bus system is so complicated it seems impossible for it to diagnose faults correctly. Hope you come right.

   Thanks. Also get those 3 faults from time to time on startup but a battery charge usually puts them away for a few months at a time. I've stolen my Series battery and put it in the disco now. For testing purposes.

   Hi Jeandre

   I have had a similar issue on the FFRR. It would give me a ASU fault and the insufficient pressure - primary fuel pump message when polling diagnostics. Charge up the battery and all was well for about a month.

   Turned out to be oxidated contacts from the alternator feed to the main battery positive terminal clamp. Remove both battery clamps and clean all contacts very well. Spray with a contact cleaner. Disassemble the positve terminal clamp and clean the mating surfaces. Also spray with contact cleaner. Fit both battery clamps back (always first positive and negative last when refitting. For removal reverse the procedure. Smear some coppaslip onto the top of the battery poles. This will prevent the forming of cristallisation of battery acid around the terminals.

   If there is oxidization present on the mating surfaces, alternator output is reduced, which over time will lead to a drop in system voltage, which then brings up those faults.

   Good luck!

   Thanks for the advice.

   When i fitted the battery that i took out of my series i noticed the negative terminal doesn't clamp to well. I'll get a new terminal tomorrow. Battery terminals are perfectly clean thanks to terminal spray on there. I took it for spin this afternoon and no faults yet, but it was only a few km's so I'm not getting my hopes up yet.

   Hi Jeandre

   on the D3 you need to tap the negative terminal home with a 1/4" extension until it sits right at the bottom of the battery post. Only then can you tighten the nut. Otherwise the terminal will be loose. If not corrected it can cost you an alternator.

   I lost 2 alternators due to the battery terminal not having been tightened properly. Only since I have started to use LRXtreme (Walter) have I received the D3 back from the workshop with terminals properly tightened. Once I realised what the problem (alternators) was, I was furious. But what can you do.

   Hi George.

   The terminal was right at the bottom. I fitted one from the spares bin and it clamps way better. Haven't had any faults come back yet but didn't drive it to much today either. Heres hoping that the other battery fixed it.

   So I've been doing some driving over the last few days and fault hasn't been back yet. I parked the Disco last night in Off-Road mode and pulled fuse 26, none of the corners sagged, but when starting it this morning the compressor started running, for about 30-45 seconds and then stopped. Is this normal or is it the reservoir that is leaking.

   TIA

   Hi Jeandre

   that is normal, the compressor will run until the reservoir has the required pressure build up and then it will stop. Compare it to a workshop compressor

   Same basic shut off method used.

   Concerning the battery:

   Swambo's D3 gave me the HDC fault when I tried to start her yesterday morning. So off came both battery terminal clamps and separated the red lead from the alternator to the terminal assembly, followed by vigorous cleaning with wire brush and emery paper, finishing off with contact cleaner spray and then re-assembly.

   And finally a full charge with the 7A CTEK. Now all is good again and she shows full charge voltage (before was 14.1V).

   I have found that cleaning these contact areas every 5 years or so will prevent unnecessary grief.

    Hi Jeandre

    Just remove both battery terminal clamps (negative first) then remove the red alternator feed cable to the red positive assembly and clean thoroughly with wire brush and emery paper. Then spray with contact cleaner and reassemble. Connect positive clamp first and negative clamp last.

    That will give you peace of mind for the next couple of years. But keep a close eye on the alternator charging. If it falls below 14V (after having done the above work) then it is on its way out.

    kind regards

    George
