Understanding Top Injectors' Core Deposit System

When ordering a reconditioned part from Top Injectors, such as a high-pressure pump or a transfer case, you'll encounter our core deposit system. This system is integral to our exchange model, ensuring a swift supply of OE-genuine reconditioned units while promoting the sustainable re-use of components.

How the Core Deposit System Works

Top Injectors operates on an exchange basis for many of our reconditioned parts, including diesel fuel injectors, high-pressure pumps, and transfer cases. This means that instead of waiting for your specific unit to be reconditioned, we dispatch an already reconditioned, bench-tested unit to you immediately. To facilitate this, a refundable core deposit is charged at the time of purchase.

Once you receive and fit the reconditioned part, you return your old, faulty unit – known as the 'core' – to us. Upon inspection and acceptance of your returned core, the deposit amount is fully refunded to you. This system allows for faster service and ensures a continuous supply of reconditionable parts.

What Disqualifies a Core from a Refund?

For a core to be eligible for a full refund, it must meet specific criteria. The core must be complete, undamaged beyond normal wear and tear, and of the exact same part type as the unit you purchased. For example, if you purchased a reconditioned BMW xDrive ATC45L transfer case, your returned core must be an original BMW xDrive ATC45L unit.

Common reasons for a core being disqualified include: significant physical damage (e.g., cracked housing, impact damage), missing major components, or being a non-genuine or aftermarket part. Cores that are completely dismantled or have been previously tampered with to an irreparable extent may also be deemed ineligible. Our assessment ensures the core is suitable for our OE-genuine reconditioning process.

Why Do Deposit Amounts Vary?

The core deposit amount is determined by the type and complexity of the part. This reflects the inherent value of the core unit itself and the cost associated with its potential reconditioning. Larger, more complex, and more expensive components naturally carry a higher core deposit.

For instance, an injector core deposit is £40, while a high-pressure pump core deposit is £80. A transfer case, being a significantly larger and more intricate assembly (such as BMW xDrive ATC13-1/ATC13-2/ATC35L/ATC45L, Porsche, or Mercedes units), has a higher core deposit of £250. This differentiation ensures that the deposit accurately covers the cost of replacing the core if it is not returned or is deemed unsuitable for reconditioning.
