VAG AL951_8HP90 TCU Clone & Programming Service

VAG AL951_8HP90 TCU Clone & Programming

This is a 1-to-1 cloning service for the VAG AL951_8HP90 automatic transmission control unit. When one of these units fails, a bare replacement won’t run until its data is matched to your vehicle — normally a dealer coding and immobiliser-synchronisation job. We read the data from your original AL951_8HP90 and write it onto a matching replacement, so the unit you get back is a genuine plug-and-play match: no dealer flash, no immobiliser pairing, and no key re-coding after install.

Vehicles this unit may be fitted to

The AL951_8HP90 is an OEM transmission control unit. It is used on DSG-equipped models.

Exact fitment depends on the engine, transmission, market and model year, so please send us your part and software numbers before ordering and we’ll confirm your unit is an exact match.

Common faults we see

Typical transmission-controller symptoms include harsh or delayed shifts, slipping, juddering, limp mode, gear-selection faults and loss of communication with the transmission. Cloning to a healthy unit restores normal operation while keeping your adaptation and security data.

What we copy across

Working from your original TCU, we transfer the complete flash and calibration, your VIN, and your immobiliser (immo) data onto the matching replacement AL951_8HP90. Every value lines up with what your vehicle expects, so the cloned unit installs ready to run.

How ordering works

1. Order this service and complete checkout.
2. Ship us both units — your original AL951_8HP90 and the matching replacement — or drop them off at our Calgary shop.
3. We clone your data onto the replacement and bench-test it, usually within 24 hours of arrival.
4. We return the finished TCU ready to install.

Turnaround, shipping & warranty

We’re based in Calgary and welcome local drop-off from Calgary and the surrounding communities, with Canada-wide and international shipping for everyone else. All cloning work carries a 12-month warranty and a 100% money-back guarantee.

Before you order

We need to read your original unit to copy its data, and your replacement must be the correct matching AL951_8HP90 hardware. If your original is completely dead or you’re unsure the two units match, message us with your part and software numbers first.
