What Our Audi & VW Customers Say
“Audi A6 ECU failed — no-start, no communication. Dealer wanted $2,100 for a new unit plus coding. ShipYourECU repaired mine for $349 and returned it coded. Flawless.”
“DSG TCU on my GTI was causing harsh jerky shifts. VW dealer said new transmission. Got the TCU repaired for $219. Shifts smooth as new. Money-back guarantee sealed it.”
“Immobilizer on my Passat locked me out completely. The expertise here is real — they knew the IMMO procedure cold and had it back working in three days.”
Audi / VW ECU Repair FAQ
What makes Audi / VW ECU repair different from other brands?
VAG-group (Volkswagen Audi Group) vehicles use a tiered immobilizer system (IMMO1 through IMMO5 depending on model year) that ties the ECU, instrument cluster, and key together. Repairing or replacing any of these modules requires proper IMMO coding to re-sync the system — otherwise the car won’t start. We perform this coding as part of every repair, which most generic ECU shops cannot do.
Can you repair VW / Audi DSG or S-tronic TCUs?
Yes. DSG (Direct Shift Gearbox) and S-tronic TCU failures — causing shuddering at low speed, harsh shifts, or limp mode — are repairs we handle regularly. We repair the TCU at the component level and return it coded for your vehicle. Contact us with your fault codes to confirm the TCU is the root cause before shipping.
Do you repair Audi / VW TDI diesel ECUs?
Yes. We repair ECUs for 2.0 TDI and 3.0 TDI engines across Audi and VW platforms including A4, A6, Q5, Q7, Jetta, Passat, and Touareg.
Will the repaired ECU need dealer coding after I install it?
No. We perform all required IMMO coding, adaptation, and key registration before shipping it back. Most VAG-platform vehicles are plug-and-play after installation. We include any vehicle-specific post-install notes with your return shipment.
How long does Audi / VW ECU repair take?
Most repairs complete in 48–72 business hours from receipt. Rush 24-hour service is available for an additional $75–$100.
