03L906023SD
ECU Cloning

Part number 03L906023SD is printed on the label of a PCR2.1 engine / gearbox control unit, found in Volkswagen Polo 1 5 TDI. If yours has failed we copy everything from it, including the immobiliser data, onto an identical donor unit, so the donor plugs in and works with your existing keys. No dealer coding, no new keys.

Seen in: Volkswagen Polo 1 5 TDI

Method: Service-mode clone (VAG MEDC17, SIMOS, PCR2.1), read bench - boot. See every PCR2.1 number and vehicle →

Post it in — order online Book the workshop

Post both units (original + donor) with your reference, or book a slot and we remove, clone and refit at Ammanford.

How it works

  1. Find a donor. A used unit with 03L906023SD on its label (the same hardware and software number as yours). Breakers and online marketplaces list them by this number.
  2. Order online. Pay securely by card, Apple Pay, Google Pay or Klarna and print the packing slip.
  3. Post both units to us (or drop them in), marked which one is the original. A tracked service is best.
  4. Cloned and tested the day they arrive, then posted back tracked. Fit the donor and drive.

Good to know

Everything copied

Software, calibration and immobiliser data go across, so the donor behaves exactly like your original with your existing keys.

Original must be readable

Most failures are in the drivers or power stages while the memory is intact. If the original cannot be read at all we contact you before doing anything else.

Not sure it’s the same unit?

Send a photo of both labels to 07424 242 414 and we’ll confirm the donor matches before you buy it.

Same unit, other labels

Other numbers printed on PCR2.1 units

Different label numbers, same family. A donor must carry exactly your number; check the last characters on the label.
