2020 LDV D90 Pricing and Specs

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.

It’s often the case that the spot you see water entering the car is not where the actual leak is located. Water can take all sorts of interesting routes on the way to where you can see it, being driven by both the air passing over the car and following the odd shapes and profiles that make up the bits of a car’s body you can’t see.

But believe it or not, one of the best ways to find the source of a leak is to sit in the car while somebody on the outside trains a garden hose in specific places. As the aim of the hose moves, you might find the leak increases and decreases, helping you pin-point the source.

This cause of a water leak can sometimes be as simple as a small twig or leaf stuck in a door rubber, but it can also be the result of a damaged seal, body damage and even a replacement windscreen that has not been sealed properly.
