LDV Problems

The most likely cause of this is a Diesel Particulate Filter (DPF) that is either blocked or on its way to becoming blocked and needs cleaning. Soot build-up in a DPF can restrict the flow of exhaust gasses, at which point you might also find the car’s computer will limit performance to avoid doing damage to the engine.

You can either try to force the DPF to regenerate, or you may have to have the DPF manually cleaned or even replaced.

The other possibility is a problem with the Exhaust Gas Recirculation (EGR) valve which can also become clogged with soot and affect the vehicle’s performance and emissions. Either way a check up at a workshop with the appropriate scanning equipment is necessary.

There’s probably a very simple solution to this involving a wire that has been disconnected during the transmission replacement, and not reconnected afterwards. You might find it’s a wire to a sensor that has been bumped or disconnected, and without this, the engine doesn’t know it is below operating temperature and, therefore, doesn’t richen the air-fuel mixture to compensate.

This compensation is how modern, electronically controlled vehicles make do without an old fashioned choke lever. But if the wiring isn’t connected and the sensors all working, the car doesn’t have the information it needs to run properly under all circumstances.

What the dealer is saying (most likely) is that the fuel pump will be fixed under warranty but there’s a question mark over the condition of the intercooler. They’re probably separate issues. If the intercooler has failed because of faulty materials or manufacture, then it would be covered by the warranty. If it’s been damaged (a flying rock, perhaps) then it won’t be covered by warranty. At which point, you’re liable for the cost of repairs and diagnosis.

The question you need to be asking is why the dealer thinks the intercooler needs to be tested. Is there anything leaking from it? Are there any performance problems pointing to the intercooler being damaged? If not, it’s hard to imagine why the intercooler would need to be tested in the first place, apart from the manufacturer warning dealers of potential failures. Which, again, would point to a warranty issue.

Don’t be afraid to ask the tough question before any work has commenced, and don’t forget that your state motoring club is a good source of legal advice on this stuff.

But you should also know that this model was involved in a safety recall to address a problem with the cooling system where a failure of the plumbing could allow coolant to escape. If this is part of your problem, it would very likely be considered a warranty job.

From what I can gather, some newer cars (and the LDV may be one of them) play the indicator and reverse buzzer wounds through the car’s stereo. If, then, you have accidentally muted the sound system, those noises will also be muted.

Find your car’s owner’s manual which should have a section on muting and unmuting the stereo system. That’s the first thing to try. You could also dive into the menus on the touch-screen to see if there’s a function there for muting the indicator and other sounds. The other function to look for is a 'restore factory settings' button which should take the vehicle back to how it was delivered brand-new.

If none of that works, you could always try an LDV dealership which has probably seen this a hundred times before and will be able to quickly reinstate these functions for you. If you’re a regular servicing customer, they may not even charge you for the five minutes it will take. And if they can’t fix it, it then becomes a warranty issue anyway.

Start with the basics, including checking the fuse(s) that control these functions. But don’t dig too deep, because this is a warranty issue and is LDV’s responsibility to fix. The only exception would be if somebody other than LDV has fiddled with the car or somehow modified the dashboard or wiring. That could include an aftermarket workshop fitting auxiliary lighting or even possibly a different stereo head unit. Beyond that, it’s a pretty straightforward case of a warranty claim. Don’t make it your problem if you don’t have to.

For a start, your vehicle at just over five years of age is only just out of its five-year warranty. So it would be worth contacting LDV Australia’s customer service department to see if there’s any help available for a fix, or to cover some of the costs of a fix.

Meanwhile, a lot of these plastic add-ons are attached via small plastic clips and it’s these that fail, allowing the part in question to fall off. In the old days, such a trim piece would probably have been made of metal and been secured by metal tabs or pins or even a nut and bolt. But there are some really good adhesives on the market now that would probably have the strength to effectively glue the trim piece back on. That will make getting it off again (if you ever have to) a bit messy and could damage the paint underneath, but it’s probably better than having to replace a strip of tape every few weeks.

Conventional wisdom suggests that a modern electronic fuel-injection system is smart enough not to flood an engine when starting., However, experience tells me that sometimes, you can get excess fuel into the engine if it doesn’t fire straight away. However, if you keep trying to start it, that fuel should pass through the engine, and it should eventually fire. So, I’d say your problem is something else.

A mechanic would probably start by checking things like whether the fuel pump is operating, the fuel and air filters, fuel pressure and whether the fuel injectors are pulsing when they should be. Your problem is likely to be a shortage of fuel rather than too much of it, so checking the fuel delivery pressure and rate is a critical step.

This make and model has a reputation for leaking transmission fluid either through breather outlets or plugs that should seal but don't. And one of the first signs that a transmission has lost fluid is a refusal to select a gear. Everything an automatic transmission does is through hydraulic pressure. Lose enough fluid over time, and there's insufficient pressure to make the vehicle move.

The good news is your vehicle should still be under factory warranty, so take it to an LDV dealership to be assessed. But don’t try to top up the fluid and drive it there, as this could cause more damage if the problem is something more complex.
