Please use the original manufacturer number of your existing (old) fuel injectors as a guide when ordering. You can also contact us if you need help.

All necessary spare parts such as seals etc. are already supplied integrated on the injectors. If the screws and copper sealing rings can be seen in the preview images, these will also be included in the delivery.

The corresponding test reports are included in the package with your order.


We are happy to provide you with written and verbal advice from our qualified English, French and German-speaking staff.

We offer written support in other languages.

This is only a guarantee payment, which serves to ensure that you return your old parts to us on time. After your old parts have arrived at our warehouse, you will be refunded your deposit using the same payment source.

You can pay either by PayPal, credit card or bank transfer.

You must pay your deposit within 7 days of receiving your order. If this 7-day period is exceeded, the order will be automatically cancelled.

The deposit amount of €50 applies to each piece.

Unfortunately, this is not possible. You must first pay the deposit so that your order can be dispatched. Old parts that are sent in advance cannot be accepted and will be returned to the sender immediately after receipt of the goods.

You will receive a notification about the payment details via the e-mail address ‘info@dieselfixneuss.com’. You must follow these when paying by PayPal, credit card and bank transfer. For all payment methods, you must provide your username and order number so that we can correctly allocate the payment.


We ship with UPS and GLS.

We dispatch on the same day after receipt of payment of the deposit.

Delivery within Germany takes 1-2 working days. For the remaining European countries on average 2-3 working days and outside Europe 3-4 working days.

Unfortunately, collection from our warehouse is not possible. We only work with a shipping system.


You must dispatch your old parts within one month of the purchase date at the latest. If you need more time, you must inform us in good time so that we can extend your deadline by a maximum of one additional month.

You will receive a deposit slip in the parcel with your order. Please return your old parts to us together with this completed deposit slip at your expense.

Unfortunately, this is not possible. Since the shipping costs are at your expense, you can choose the shipping company in your favour.
