Secondary Air Pump Delete
At Inverness Tuning, we specialise in precision ECU remapping and hardware solutions for cars, vans, and 4x4s across the Highlands. One of our most requested services is the SAP Delete (Secondary Air Pump Delete) – a modification designed to improve reliability, reduce unnecessary components, and streamline engine performance.
By removing or electronically disabling the secondary air injection system (SAP), your engine management is simplified and potential failure points are eliminated. This service is especially popular with owners of Volkswagen, Audi, BMW, Mercedes, Porsche and other performance vehicles looking for more consistent running and reduced maintenance costs.
An SAP Delete, also known as a Secondary Air Pump Delete, is the process of professionally removing or electronically disabling a vehicle’s secondary air injection system. This system was originally fitted to help engines meet emissions targets on cold start, but over time its pumps, valves and sensors often become unreliable and trigger costly fault codes. By carrying out an SAP Delete, Inverness Tuning simplifies your engine bay, eliminates a common failure point and recalibrates your ECU for smoother, more reliable performance. This expert service is ideal for owners of Volkswagen, Audi, BMW, Mercedes, Porsche and other performance vehicles across Scotland looking for improved driveability, fewer warning lights and reduced maintenance costs.
The secondary air injection system was designed to help engines meet strict emissions standards on cold start. Over time, however, these pumps, valves and sensors become prone to failure. Owners often face recurring fault codes, limp mode, or expensive replacement parts.
A professional SAP Delete from Inverness Tuning removes this weak point, updates your ECU mapping, and gives you a reliable, performance-focused setup without compromise. This service is not a simple hardware removal – it requires expert software adjustment to ensure your engine management system runs correctly, with no warning lights or drivability issues.
With years of experience in ECU remapping, performance tuning, and emissions system modifications, Inverness Tuning is your trusted partner in the Highlands and beyond. Our process includes:
Full diagnostic assessment before any modification.
Professional removal or blanking of the SAP components if required.
Custom ECU coding to properly disable the SAP function and clear fault codes.
Optimised performance remap tailored to your engine and existing upgrades.
Aftercare and support to ensure your vehicle runs reliably and efficiently after the modification.
Whether you drive a daily commuter, performance car, or light commercial vehicle, we provide a comprehensive, legal-compliance-aware service with the highest standards of workmanship.
