Have any of you gone one stage further and checked the other ends of the battery cables, input cables to fuse box, earth leads? What I'm thinking is that you might have all the power you could ever want, at the battery, but is it getting where you need it, and has it got a good return path to the battery?

L322 trans fail fault

They say it is a chip fault that flashes up the unnecessary warning randomly and requires a new motherboard. However as it doesn't affect the cars performance and it doesn't occur on all cars it isn't something they want to replace even under the extended warranty. I trust this garage, they have so far been very straight regarding other issues and replaced other stuff at short notice under the warranty without fuss.

I don't use the HDC feature on a regular basis so I would be interested if any one has this warning and then finds the HDC won't engage. AnthonyLMay 28, I have had the same HDC inactive ping when starting the car ,only if its stood for longer than hours.For further advice on the following issues phone our service department on or email service kmotors.

Initial symptoms would usually be a reluctance to shift gear or the appearance of engine management or gear monitor faults on the dashboard. If the problem is not attended to the next symptom would normally be a chattering noise under drive.

If the any of these things occur it is best to stop driving the vehicle immediately and take it to the place of repair by recovery truck or on tow. Most will require the vehicle plugging into diagnostic equipment to find the exact cause however the most common faults are EGR valves or a split in one of the intercooler hoses.

5 Common Faults on a Used Range Rover (L322 Model)

This means that the air boost pressure is lost so the air and fuel mixture is incorrect leading to poor performance and generally black smoke from the exhaust. Most instances will put the car into restricted performance mode but not always. This is most common on the 3. We would always advise to change both hoses even if only one is faulty as the other will fail shortly after.

These are the bushes that connect the hubs to the wishbones and the usual symptoms are clonking noises from the rear suspension when driving over bumps. The bushes are quite difficult to replace, requiring LR special tools and a fair amount of elbow grease. Electrical faults ranging from engine not starting as easy as usual or not at all to dash lights flickering etc can be caused by a faulty alternator particularly on the 3.

It is easy to test if your alternator is working properly if you have a multi-meter, with the engine running hold the prongs on to the negative and postitive terminals of the battery you are looking for readings of between If the reading is outside of those parameters then the alternator is faulty and needs replacing. Unfortunately they are not easy to get at and it takes around 4 hours to replace.

While offering superior ride quality and excellent off road ability all round air suspension has helped set it apart from its rivals. However, there are a lot of components in the system and faults are commonplace. The car will then be very slow to raise or not raise at all and only go into standard ride height will not go in off road or access mode occasionally it will introduce restricted performance the dreaded limp home mode. Other issues can be one or more corners will not raise. The same symptoms and warnings can be caused by any of the following issues priced below.

We would always advise a full diagnostic check to narrow down the cause before changing any parts. Even though the majority of the suspension components are heavy duty parts they are on a vehicle that weighs the best part of 3 tons so eventually they are going to give.

A rattle heard when travelling over rough terrain often felt through the steering wheel is a common complaint but diffcult to diagnose as you can test all bushes with a bar or jack vehicle up and look for play but not see any. It needs a ramp and someone to rock the steering wheel quickly side to side whilst another person looks for excessive movement in all the bushes and ball joints, the most common to go is the front suspension lower ball joint and it is easier to replace the whole arm than try to replace just the bush.By ngb13January 2, in Range Rover Forum.

I have a L 4. It has done 63 miles. About 2 weeks ago shortly after start up the dash display flashed up 'Transmission Fault' then something like 'limited gear selection' and 'Suspension Lowering', the warning dash light and traction control dash light then remained on. I switched the car off and re-started, after which the car was fine. The next day the car flashed up 'HDC Fault' and the Suspension Lowering', again when turned off and back on the fault cleared.

Over the last 2 weeks the car has registered these same faults almost everytime its been driven about 15 timesusually its just the HDC warning that flashed up but sometimes it flashes the Transmission warning and on occasions it has flashed up both warning one after the other. I have taken it to a Land Rover specialist who ran a diagnostic check and could only get 'Module BUS' or similar, they said the ECU didn't seem to be talking to a module properly?

They did a hard reset what ever that means but the faults persist. There doesn't seem to be any pattern to the fault warnings - sometimes its within a minute of start up, other times its 40 mins into a journey cruising at 50MPH on the motorway roadworks. Car had an LPG conversion 2 days prior to these faults starting to occurr, this involved the battery being disconnected for 3 days and also the air compressor being moved from the spare wheel compartment, although not disconnected or anything and the faults don't seem to coincide with the air suspension being operated.

Car always sinks to its bump stops overnight, although it has done this for the last year or so I intend to get this repaired in the near future. Side bars were fitted day prior to the faults starting, although they simply bolted on and didn't involve anything being disconnected or anything.

Is there anything I can do myself to try and diagnose the cause without sending it to the dealers who will no doubt want a few hundred quid to look at it!

JP, I did indeed get to the bottom of this problem and you will be pleased to know that it is actually pretty straight forward ish! This had upset the very sensitive CAN BUS system on the RR and so the answer was to disconnect the two wires that had been spliced into the car's original wiring and repair the wiring so that the car didn't know it had ever been spliced into.

Since I had this done I have had no probs with any faults flashing up. It is easy to check if your installers have spliced into the system, just remove the side panel of the dash by your right knee and have a look to see if the wiring is original.

However, the only problem is that those two wires were supposed to monitor and adjust the fuel trims to stop your engine warning light being triggered by the trims going slightly outside the car's parameters.

My LPG installer's are still working on an alternative fix for this issue and it looks like the best option is to try and tune the LPG fuel settings to such a fine degree that the trims don't exceed the parameters. The first problem I have though which is different is that recently, before the faults appeared, it had been sticking in low gears - not changing up till about 4.Forums New posts.

l322 hdc fault

L trans fail fault. Thread starter Mark Phillips Start date Jul 23, Mark Phillips In Second Gear. Messages 5 Points Bemble Overdrive! Messages Points Welcome to the forum Mark. There were five different transmissions fitted in the L during its production run.

Could you specify which model and year you have? Hi Phil it is the GM box in a l Hopefully your problem is just temporary and is in some way related to water ingress and the electrics. That generic DTC is for a shift fault. I would check the transmission fluid for 'glitter' metallic debris and it might be worth swapping the solenoid over with one of the others and see if the problem moves with it. Thanks for the advise and pics latest is that I've purchased a icarsoft i and the fault now showing after clearing the others is p and once only p so I think I will follow your advice and take a look at the oil and solonoids before submitting to a gearbox specialist the car drives normal to 30mph in drive but then just goes the fail safe there's no variation it does it every time Off to Billing LR show now so may find someone that's had the same thing Cheers Mark.Forum Rules.

Remember Me? Results 1 to 9 of 9. Thread Tools Show Printable Version. Hi Folks Greetings from Ireland, yes we buy L's here as well. This is my first post on this very entertaining and usefull site, so I'm hoping somebody has overcome my problems listed below. I am able to clear down the error using the functions in the instrument cluster, and provided I use the car on short journeys, the error lights do not re-appear. However, I have had to make 6 x mile journeys over the last 2 weeks and on each journey, like clockwork, 20 - 25 minutes or 15 miles or so into the journey, I get the "ping" and all 3 error lights flash up.

The ride height reverts to standard from motorway and the ride height locked indicator comes on. Car handles fine so far and I have been able to continue my journey.

HDC & Air suspension problem L322

When I get to my destination, I have been able to reset the error lights and the cycle continues!!!! The issue arose for the first time a couple of weeks back, when I was turning into the entrance of a friends farm, and had to accelarate to avoid a speeding car coming the other way. In accelerating over the cattle grid, the abs light flash and when I put my foot on the brake pedal, I could feel the tickle through my foot that mean't the ABS had engaged.

Not sure if this had an impact, but the other error lights appeared quite soon after this event. Other than the error lights, the car and suspension is behaving normally, regulating the height as required and the suspension is level and all ride heights are achievable. Took the plunge and got my hands on a Hawkeye and it showed the error message "Implausible steering angle" which I took to mean the Steering Angle Sensor.

As the car had been tracked and balanced just before the errors noted above had surfaced, I recalibrated the SAS before heaing off on a road test. Anyway, right on cue, errors re-appeared. I assume therefore that the SAS needs replacing. Has anyone out there done this and could you let me know whats involved? Regards Ed.LandyZone is the biggest Land Rover forum on the net.

My battery was really weak and the car would not start because there was no power but when it would the Air Suspension Inactive light would come up and I wouldn't be able to change the settings. But when it was on and you drove it for a few mins the air suspension would go back to normal and you can control it.

So I decided to change the battery and bought a new batt but the suspension light won't go off now even when you drive it.

I cant control the suspension at all. But when you get out of the car the suspension rises it self to normal ride height so there won't be anything wrong with the air compressor?

Or suspension legs? Anyone have any ideas what I can do? Before I take it to dealers and they have my pants down. I've also got a brake fluid leak down passenger side but that can't be causing the problem can it? TD6SheffieldNov 6, Without question, Land Rover is one of the finest sport utility vehicles on the market.

Their performance and overall capabilities are unparalleled, earning them a dedicated following of enthusiasts. Like all luxury vehicles, the Land Rover is not immune to issues that are specific to this make. The HDC capability catapulted the Freelander to legendary status as a premier off-road vehicle and the technology was later featured in both the Range Rover and the Discovery modelsas well. In many ways it is a similar innovation as Cruise Control. Like Cruise Control, the driver can override the HDC system by applying either the brakes or the accelerator.

HDC technology is extremely important for maximum control and safety in an off-road setting on steep declines. When it fails, you have significantly less control over the vehicle. An error will appear on the dashboard of your Land Rover to notify you that the HDC is not functioning. There are actually several messages that may appear to indicate issues with your HDC, but not all of them mean your Land Rover is in need of repair.

Reducing your speed will allow you to activate HDC. Should your brake system be especially taxed and overheating, HDC will not be available and your vehicle will indicate System Cooling.

HDC requires low range gears to operate.

l322 hdc fault

It can also be used in 1Dand R in high range, so if you see a message that indicates HDC Not Available in this Gear, make the appropriate gear selection and re-try. If you see this message, you are experiencing HDC failure and should take your Land Rover to a certified mechanic as soon as possible. Do not attempt to descend any steep gradients with an HDC failure as it could lead to lack of control and a dangerous descent.

The good news about HDC failure is that very often it is an incredibly easy problem to solve. Your HDC system is extremely sensitive to incorrect battery voltageso in many cases, just changing the battery in your Land Rover is the solution.

However, if the battery is not the issue there could be a wide range of potential problems from other power-related components like the alternator to issues with the transmission and braking system. The most important thing you can to do to prevent HDC failure is to have regular preventative maintenance by a qualified Land Rover mechanic. Should you have any issues with the HDC system, it is critical to make an appointment right away to ensure that your vehicle is thoroughly inspected for any other related mechanical issues.
