When an engine ECU is lost, damaged, or unreadable, the vehicle’s immobiliser can prevent it from starting. Dealer replacements can be slow and expensive. Our VAG Immobiliser Bypass Service restores drivability by safely disabling or reconfiguring immobiliser protection in VAG ECUs (Audi, Volkswagen, Seat, Skoda, Bentley) so your vehicle can be started and driven while you arrange a permanent repair or replacement.
We use manufacturer-grade tools and controlled procedures — not crude hacks — and we document every step to keep your vehicle compliant and traceable.
Who this service is for
Owners or workshops who cannot clone a lost/damaged original ECU.
Vehicles where the donor ECU is incompatible or the original ECU is unreadable.
Fleet managers needing quick turnaround to return a vehicle to service.
(Covers Audi, Bentley, Seat, Skoda, Volkswagen ECUs.)

Important notes & safety
This service is provided to legal owners, authorised workshops or agents only. By sending the ECU you confirm you have the right to request this change.
Severe physical damage (broken pins, heavy corrosion) may prevent a bypass — send photos first.
Immobiliser changes can affect warranty or insurer requirements — check with your provider if unsure.
FAQs
Q1: What is a VAG immobiliser bypass?
A1: A VAG immobiliser bypass is a professional service that disables or reconfigures the immobiliser protection inside an engine ECU for VAG vehicles (Audi, VW, Skoda, Seat, Bentley) so a legitimately owned car can be started when the original ECU is lost, damaged, or cannot be cloned.
Q2: Is VAG immobiliser bypass legal?
A2: Yes — when performed for legitimate reasons (vehicle owner request, authorised workshop work, or diagnostics). We may request proof of ownership and we do not assist unlawful activity.
Q3: Will my existing keys still work after the bypass?
A3: In many cases yes — we preserve or transfer key data where possible so existing keys remain functional; we will confirm during assessment.
Q4: How long does the VAG immobiliser bypass take?
A4: If we receive the ECU before 1pm we usually complete the bypass the same day. Postal returns are sent via next-day tracked delivery.
Q5: Do I need to send the immobox or keys as well?
A5: Usually the ECU alone is sufficient, but some ECU types require the immobox or keys. After you submit the part number or photos we’ll confirm exactly what to send.
Q6: Will a bypass affect my car’s warranty or insurance?
A6: It can in certain circumstances. We recommend checking with your insurer or warranty provider; we’ll advise on likely impacts during pre-check.
Q7: What if my ECU is physically damaged or water-damaged?
A7: Severe physical damage may prevent a standard bypass. Send clear photos first — we’ll assess and quote for repair or replacement options if needed.
The service will be done and posted back the same day.
