About Volkswagen
Volkswagen is the parent to many kids and known for its huge variety of German cars and vans, from the Polo and Golf to the Transporter that seems to carry half of Britain's tradespeople. They're solid and dependable, though a well-loved Golf can develop a few electrical habits with age.
AutoECU covers almost every Volkswagen on UK roads: spare and lost keys, upgrade keys, fob repairs, factory add-on coding and module replacements for cars and vans. Our partner tuners look after remaps.

Volkswagen questions
Can you make a key for my VW Transporter or Caddy?
Yes, vans are a big part of what we do, and we cover most Transporters, Caddys and Crafters on UK roads. We can supply spares, sort all-keys-lost and deactivate missing keys. Contact AutoECU with your reg to get your van back to work.
Can you retrofit cruise control or CarPlay to my Volkswagen?
Often, yes. Many VWs can have cruise control, CarPlay and other factory extras added or activated with the right parts and coding. Send AutoECU your reg and we'll tell you what your car supports.
My Passat won't start and says steering lock fault. What now?
The electronic steering lock on B6 and B7 Passats is a known weak spot. It can usually be repaired or replaced and coded without dealer drama. Get in touch with AutoECU and we'll help.
Need something done on your Volkswagen?
We'll fill in the make for you. Just add your reg and what's wrong.
