Pair of 4-solenoid blocks for the DQ200 (0AM) 7-speed dry dual-clutch mechatronic unit in VW, Audi, Skoda and Seat 1.4L-1.8L FWD cars.
A 1.4L, 1.6L or 1.8L Golf, Jetta, Passat or Polo, an Audi A1 or A3, or a Skoda or Seat with the seven-speed dry DSG that shudders in 1st and 2nd, engages late from a stop, or keeps logging valve and gear-position faults may need new solenoid blocks rather than a whole mechatronic. This kit is the pair of remanufactured blocks, reference 0AM325473, that bolt onto the 0AM (DQ200) mechatronic. Each block carries four solenoids.
In the DQ200 the two dry clutches and the shift forks are moved hydraulically, but the oil does not come from the gearbox. A separate electric pump inside the mechatronic charges an accumulator, and the solenoids meter that stored pressure out to the clutch actuators and the gear actuators. The control module switches and modulates them hundreds of times a drive to slip the clutch on take-up, pre-select the next gear on the idle shaft and hand torque from one clutch to the other. When a solenoid sticks, leaks internally or loses its coil, the module loses accurate control of that circuit.
Do not condemn the solenoids until you have ruled out the parts that fail more often. Gears Magazine names the cracked accumulator casting as the most common DQ200 failure, and a leaking housing produces many of the same complaints because the solenoids are starved of pressure. Watch the mechatronic pressure and pump run time at idle first; if the pump cycles constantly, look at the DQ200 accumulator housing kit instead. If pressure holds and valve-specific faults keep coming back, the blocks are the repair short of a complete mechatronic. Ross-Tech also points owners to the P173A through P173F code group when those faults are present. Our DSG pressure testing guide covers the pressure checks, and the DSG mechatronic and clutch problems guide separates mechatronic faults from worn clutches.
These blocks are for the 0AM / DQ200 seven-speed dry dual-clutch used behind the front-wheel-drive 1.4L, 1.6L and 1.8L engines in VW, Audi, Skoda and Seat models. They do not fit the seven-speed wet-clutch DQ500 (0BH/0BT) or the six-speed 02E / DQ250. Match the transmission code to 0AM and compare the connector layout of your old blocks to the photos before you order, or send us your year and VIN to confirm. See the full range on our DSG and dual-clutch collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Two blocks with four solenoids each, eight in total, the full set that mounts on the DQ200 mechatronic.
No. They are for the 0AM / DQ200 seven-speed dry-clutch unit only. The DQ500 and 02E use different mechatronics and solenoids.
If the housing is cracked or the mechatronic pump runs constantly at idle, yes. A leaking housing starves the solenoids of pressure and will make new blocks look faulty.
Yes. Run the DQ200 Basic Settings with a VW-capable scan tool and then complete the defined test drive so the clutch and gear actuators relearn.
They are remanufactured solenoid blocks, reference 0AM325473.
