Jerky or delayed gear changes, a gearbox warning light, the car refusing to engage Drive or Reverse, shuddering at low speed, and fault codes such as P17BF, P189A or U010068 are all strong indicators of DQ380 mechatronic failure. Any combination of these symptoms warrants a diagnostic scan and mechatronic inspection before further driving.
The DQ380 7-speed wet-clutch DSG is fitted to a wide range of VAG group vehicles including the VW Golf GTI, Golf R, Tiguan, Transporter T6, Skoda Octavia vRS, Seat Leon Cupra, Audi A3 S tronic and Audi TT S tronic. If you're unsure whether your specific variant uses the DQ380, call us on 0203 489 2610 and we'll confirm before you send anything.
Remove the mechatronic unit from the gearbox, allow residual fluid to drain and seal open ports. Wrap the unit in at least two layers of bubble wrap, place it in a rigid cardboard box with all voids packed, and include your name, contact number and a description of the fault. Send to Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ using Royal Mail Special Delivery or a tracked courier. Free return shipping is included in our repair price.
We aim to diagnose, repair and bench-test your DQ380 mechatronic unit of receiving it. Return shipping is free and fully tracked, so most customers have the unit back and ready to refit within a week of posting. Complex faults involving both hardware and software components may occasionally require an additional day, but we always keep you updated.
In most cases the repaired unit retains its original adaptation data and can be refitted without a full dealer-level recode. However, if a solenoid or pressure regulator has been replaced, a gearbox adaptation reset via VCDS or ODIS is recommended — a quick procedure any good independent VAG specialist can perform. We advise every customer in writing on exactly what post-refit steps apply to their vehicle before we return the unit.

⚠️ Warranty Terms for This Repair
Our 12-month warranty on this repair is conditional on a full transmission oil and filter change being carried out at the time of refitting.
Please keep proof of this — a paid invoice from a garage or workshop — as this will be requested if you ever need to make a warranty claim.
This is a transmission component, and correctly completing the fit requires the correct basic settings, adaptations and teach-in procedure for your specific gearbox to be carried out afterwards for it to operate correctly.
Many owners with the right diagnostic equipment and experience fit these themselves — that's completely fine. If you're doing the oil/filter change yourself rather than at a garage, keep your own dated records (receipts for the oil/filter, and confirmation the adaptations were completed) as equivalent proof for a claim.
The list above covers our most requested services — but it is far from everything we do. If your unit is not listed, get in touch. Our technicians have most likely seen it before and can help.
