One of the most common failures of N54 powered BMWs is MSD80 (DME aka ECU). Usually MOSFETs inside the DME fail on load.
This is when you should upgrade your MSD80 to MSD81. You only need to send us your CAS module and one of your keyfobs.
You can also send us your injectors flowing rate numbers and we can code them in before sending your items back to you.

We have a 20-day return policy, which means you have 20 days after receiving your item(s) to request a return. Please note we charge a 25% restocking fee on all returns. To be eligible for a return, your item must be in the same original/new condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. To start a return, you can contact us at Sales@ColoradoN5X.com. Items sent back to us without first requesting a return will not be accepted. You can always contact us for any return question at Sales@ColoradoN5X.com. Please inspect your order upon arrival, and contact us immediately if the item is defective, damaged or if you received the wrong item, so that we can evaluate the issue and make it right.
Certain items cannot be returned, like sale items, perishable goods, custom products (such as special orders or personalized items), hazardous materials, flammable liquids, and/or gases.

The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.
We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method.
