It is the electro-hydraulic control module inside your DSG gearbox, combining the valve body, solenoids, sensors and transmission control unit that manage clutch engagement and gear changes.
Jerky or harsh gear changes, hesitation pulling away, slipping, loss of drive, a flashing gear display and gearbox limp mode are all common symptoms.
In many cases we can repair or rebuild the unit by replacing the faulty solenoids, sensors or valve body, which is far more cost effective than a full replacement. We advise after diagnostics.
We work on all common VW Group DSG and S tronic boxes including the 7 speed DQ200, 6 speed DQ250, DQ500 and DL501 S tronic units.
Yes. A genuine DSG oil and filter service is essential after any mechatronic work to protect the new components and ensure smooth operation.
Most mechatronic repairs are completed within one to two days depending on parts availability and whether a repair or full replacement is needed.
Yes. These are clutch position sensor and shift faults on the 7 speed DQ381 mechatronic unit. P1735 affects the odd gears (1, 3, 5 and 7) and P1736 the even gears (2, 4 and 6). We repair the mechatronic unit rather than replacing the whole gearbox, which saves you a lot of money.
Both point to a hydraulic pressure problem in the DQ200 7 speed mechatronic. P17BF is the hydraulic pump overload protection and P189C means the unit cannot build enough pressure. We diagnose the cause and repair the mechatronic to clear them.
We do not recommend it. Driving with codes such as P17BF, P189C or a clutch fault can cause further damage to the mechatronic and clutches. Get it diagnosed as soon as possible to avoid a bigger bill.
Yes. Our DSG and mechatronic repairs are carried out with quality parts and come with a warranty. Contact us for full details.
It depends on the gearbox and the exact fault, but a mechatronic repair is usually far cheaper than a full gearbox replacement. Send us your fault codes and vehicle details for a quote.
Limp mode is the gearbox protecting itself. On 2017 era Tiguans fitted with the 7 speed DQ381 or DQ500 DSG it is often caused by clutch position or pressure sensor faults inside the mechatronic unit, stored as codes such as P1735, P1736 and P1738. You can suddenly lose either the odd gears (1, 3, 5 and 7) or the even gears (2, 4 and 6). We diagnose and repair the mechatronic to get you out of limp mode.
A 2017 Tiguan is usually fitted with the 7 speed DQ381 or DQ500 DSG. Both are boxes we repair. Mechatronic clutch position and pressure sensor faults are common on them and we can usually repair the unit rather than replace the whole gearbox, saving you money.
The mechatronic controls each of the two clutches separately. When the position or pressure sensor for one clutch fails you lose the gears that clutch operates, either the odd gears (1, 3, 5, 7) or the even gears (2, 4, 6), and the gearbox drops into limp mode. It is a classic mechatronic fault that we repair.
