From the CTS and ATS saloons through to the electric Lyriq, Optiq and Escalade IQ, Autotech UK offers plug-and-play mileage blockers for a broad spread of Cadillac models. Every Cadillac module keeps the speedometer working and is covered by a 12-month warranty.

Long cable and app control
The newer-generation modules for the CT4 and CT5 (2021 onwards), the 2020–2026 Escalade and all of the electric models come with a long cable and app control. The remaining modules, including the ATS, CTS, CT6, XT4, XT5, XT6 and 4th Gen Escalade, do without these extras.
Fitting
Each module fits behind the instrument cluster with no cutting or soldering. DIY instructions are supplied, and we’ll happily talk you through it on a free video call. Alternatively, book our nationwide fitting service at checkout (UK only). Express tracked shipping is available.
FAQs
Which CT4 or CT5 blocker do I need? There are two versions of each: a CAN bus module for 2018–2020 cars and a newer module for 2021 onwards. Check your model year before ordering.
Is the Escalade IQ covered by the standard Escalade module? No. The electric Escalade IQ and IQL (2024–2026) have their own dedicated module.
Are mileage blockers legal? Fitting and using a blocker for testing, diagnostics, track days or off-road use is legal in the UK. It is illegal to mislead a buyer about a vehicle’s mileage, so always declare it when selling.
