Product Overview

What this part is — and why it fails.

The DQ250 is the VW (02E / DQ250) 6-speed wet dual-clutch fitted to VW Golf GTI, Passat, Audi A3, Skoda. This page covers the tcu / tcm control unit for that platform, supplied by Guangzhou Meishun (TRANSMESUN) — a CE-certified remanufacturing factory in Huadu, Guangzhou, with 20 years in the transmission trade.

High-volume wet DCT: mechatronic wear and clutch-pack wear are the documented areas. That failure chain is exactly what our process is built around: the part is inspected against the platform's documented wear points. Function-checked per unit; variant/OE number matched and recorded before dispatch. Every order is verified against your transmission code before anything ships.

Use Cases

Who orders this part, and why.

Mechatronic failures

DQ200-style pressure-accumulator cracks and conductor-plate sensor failures have clear, updated replacement paths.

Rebuild shops

Pairing a rebuilt valve body with a verified TCU removes the two biggest comeback risks in one job.

Distributors

TCUs are late-model growth stock — hardware numbers matter, so we match by OE reference.

Applications & Fitment

Which vehicles this platform serves.

Typical applications for this platform. Always confirm against the transmission code — one car line can carry two different units by year and market.

Buyer FAQ

Questions buyers actually ask.

Do TCUs need coding after fitting?

Many platforms do. We supply the variant notes for the unit; your installer handles vehicle-side coding and adaptation resets.

How do you match the right TCU?

By OE hardware number and platform generation. Send the number from your unit or the vehicle's build data.

What if my fault is intermittent?

Intermittent faults are often conductor-plate or solenoid-related rather than the TCU itself. Send the codes first — we'll help you isolate before you spend.

How do I verify this part matches my VW unit before ordering?

Send the transmission code from the nameplate (or a photo of it). Our engineers confirm the generation and variant in writing before anything is packed — this removes the generation-mismatch risk that plagues this platform.

What are the ordering terms?

MOQ starts at one piece, lead time from 1 day for in-stock codes, 12-month quality guarantee across all product categories, export-grade packing with shipment photos.
