BMW G Series Gear Selector Repair for P Button Malfunction

What This Repairs

On BMW G Series vehicles, removing the shift knob without first disconnecting both batteries (12V and, where fitted, 48V) shorts the gear selector. The result is a "P Button Not Functioning" fault and a vehicle that cannot be shifted into gear. Rather than replacing the gear selector and having a new unit coded to your vehicle, Infinite Autowerks repairs your original selector.

What Happens After You Order

1. You'll receive an email with our shipping address, a printable packing slip to place in the box, and a secure link to enter your tracking number once the package is on its way.
2. When your tracking shows "Delivered," we have it — there is no need to call to confirm receipt. You'll receive an email confirming check-in with your estimated ship-back date, and you can follow each step on your repair tracker.
3. When the repair is complete and bench tested, we ship it back and email you the return tracking.

Turnaround

Repairs are completed in the order received. The estimate is approximately 5 business days, counted from the business day after your shifter arrives (the delivery day itself does not count). Adding conformal coating adds one business day. This is an estimate — it may be shorter or longer depending on parts availability and your place in the repair queue — and we'll keep you updated throughout.

Our shop operates Monday through Friday. Packages delivered Friday afternoon or over the weekend are checked in on Monday.

Ribbon Cable

If the ribbon cable (the white ribbon tabs or electrical contacts) was bent, burnt, or otherwise damaged during your installation attempt and you did not select the replacement option at checkout, you can purchase it here so we can fit it during your repair: Infinite Autowerks G Chassis Shifter Repair Ribbon Cable. If we find cable damage on the bench that wasn't declared, we'll email you a link to purchase the cable and the repair continues as soon as it's ordered.

Liquid Damage

If a P Button fault followed a spill or detail-spray exposure, the damage is on the main board and this listing is not the correct service. Please purchase the Main Board Replacement instead. If we find during repair that the damage extends into the main board, we'll contact you with the option to upgrade; the amount you paid for this service is credited toward it.

Shift Knobs

Most of the shifters we see were damaged during the installation of a third-party crystal knob. We do not install third-party crystal knobs. We install only the OEM knob or our own IAW OE-style crystal parts, which are designed to install safely on these shifters. If you would like your repaired shifter returned with a crystal knob already fitted and bench tested, order it before your unit arrives and we will install it free of charge as part of the repair: IAW OE-Style Crystal Shift Knob or the complete IAW OE-Style Crystal Kit (shift knob, start button, media dial, volume knob). Any third-party knob included with your shipment will be returned uninstalled.

Optional Conformal Coating

A clear protective layer applied to the repaired circuit board that guards against common liquid exposure — coffee spills, interior detail spray, and other moisture — and helps extend the life of your repaired shifter. Add it at checkout (adds one business day). We also offer coating as a preventive service for fully working shifters; contact us to arrange it.

Diagnostic Minimum

A $199 diagnostic minimum applies to every shifter we evaluate. If you send your shifter in and decide for any reason not to proceed with the repair, the $199 minimum plus return shipping of your choice applies, whether or not the shifter is repaired.

What to Ship

Ship the complete gear selector module — not just the knob. You may remove the iDrive controller or leave it attached. The picture below shows exactly what to send. Please include the packing slip from your confirmation email (or a note with your name and order number).

Ship Your Shifter To

Infinite Autowerks LLC
15343 Beck Rd.
#150
Northville, MI 48168

Shipping the shifter to us is the customer's responsibility; use any carrier and service you like, and enter the tracking number through the link in your confirmation email.

Return Shipping (included in the price)

• UPS Ground — within the yellow and dark orange regions on the map below. You'll receive your shifter back in 1 business day (yellow) or 2 business days (dark orange).
• UPS 2-Day Air — everywhere else in the lower 48 states. Included at no extra cost.
• UPS Next Day Air — optional upgrade (+$50 at checkout). Applies to the return shipment only; it does not shorten the repair time. Available within the lower 48 states; contact us for a quote elsewhere.

If you ship to us with a 1-day service and choose the Next Day Air return, the total time without your shifter is typically the repair estimate plus 2 business days.

International Customers

You are responsible for all customs, import, duty, and tariff charges on your shipment, both to us and on the return. Please monitor your tracking and pay any charges promptly when billed by the carrier or customs so your shifter is not delayed. If a bill is sent to us instead, we will forward it to you for payment.

Local Customers

If you would like your gear selector repaired locally, we can schedule a dedicated time, often same day if arranged early enough. An additional fee applies because the work is scheduled outside our normal mail-in process. Please contact us by email or phone to arrange it. The repair price never includes labor to remove or reinstall the gear selector in the vehicle — this is a mail-in service and we do not provide on-site assistance. For local drop-off, bring the gear selector only, ready for repair. If you need help with removal, we can discuss it by phone; cost varies by vehicle.
