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.

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.

This is a complex issue and CarsGuide does not give legal advice on matter such as this. However, from a practical standpoint, water on the road in puddles could conceivably enter the engine and cause damage if you managed to hit just the right puddle at just the right speed and at just the right angle to force water into the engine’s air intake system.

In any case, this would likely (as you are discovering) be considered accidental damage rather than a warranty issue as the problem wasn’t caused by a fault in the car’s materials or manufacture. Which means you might be better off tackling your insurance company to see if such damage is covered by your vehicle policy. Damage to a vehicle from (flood) water is much more likely to be an insurance job, so start there.
