There is no dealer programming, no VIN coding, no component protection activation and no adaptation procedure. Reinstall it and the roof operates.\u003c\/p\u003e\n\u003ch4\u003eWhat is Bentley part number 3W7959255B?\u003c\/h4\u003e\n\u003cp\u003e3W7959255B is the convertible top control module for the Bentley Continental GTC. It is built by HUF and marked \u003cem\u003eVerdecksteuergerät\u003c\/em\u003e on the housing. It controls the hydraulic soft top sequence, driving the pump, valves, latch motors and tonneau cover, and reading the roof position sensors and microswitches. In diagnostic software it appears as Address 26, Auto Roof, component name VSG.\u003c\/p\u003e\n\u003ch4\u003eWhere is the convertible top control module located on a Bentley Continental GTC?\u003c\/h4\u003e\n\u003cp\u003eThe roof control module is mounted inside the cabin, most commonly under a seat or behind rear interior trim. This location leaves it exposed to water if the soft top, drain tubes or seals leak, which is the single most common cause of genuine module failure on these cars.\u003c\/p\u003e\n\u003ch4\u003eWhat causes the Bentley GTC roof control module to fail?\u003c\/h4\u003e\n\u003cp\u003eWater ingress is the dominant cause. A leaking convertible top or blocked drain lets water reach the carpet and the module underneath, and the resulting corrosion attacks the circuit board, the connector pins and the power and motor driver stages. Failures also occur from thermal fatigue cracking solder joints on high-current output devices that drive the hydraulic pump.\u003c\/p\u003e\n\u003ch4\u003eHow do I know if my roof problem is the module or something else?\u003c\/h4\u003e\n\u003cp\u003eConnect a scan tool and look for Address 26, Auto Roof. If the module does not respond at all and you have confirmed good power and grounds at the connector, the module is the likely fault. If the module does communicate and reports a stored fault such as an implausible switch or position signal, the module is alive and the problem is almost certainly a sensor, microswitch, wiring, potentiometer or hydraulic issue instead.\u003c\/p\u003e\n\u003ch4\u003eIs a new 3W7959255B still available from Bentley?\u003c\/h4\u003e\n\u003cp\u003eYes, but it is a special order part. Suppliers commonly quote a lead time of four to six weeks and a price near seven hundred dollars, and a replacement module must be adapted to the vehicle before the roof will cycle correctly. A repair of your existing unit avoids both the wait and the adaptation.\u003c\/p\u003e\n\u003ch4\u003eHow long does the repair take?\u003c\/h4\u003e\n\u003cp\u003eTypical turnaround is 3 to 5 business days from the day your module arrives at our facility. Shipping time in each direction is additional and depends on the service you choose.\u003c\/p\u003e\n\u003ch4\u003eWhat warranty comes with the repair?\u003c\/h4\u003e\n\u003cp\u003eEvery repaired module carries a 6-month unlimited mileage warranty covering the repair work performed.\u003c\/p\u003e\n\u003ch4\u003eDo I ship you my own module, or do you send one first?\u003c\/h4\u003e\n\u003cp\u003eYou ship us your own module. This is a mail-in bench repair service, not an outright sale or an exchange unit. Keeping your original module is what allows the repair to be plug and play with no coding.\u003c\/p\u003e\n\u003ch4\u003eWill this fix a roof that stops halfway through the cycle?\u003c\/h4\u003e\n\u003cp\u003eUsually not. A roof that starts moving and then stops partway is nearly always a mechanical, hydraulic or sensor problem — broken tension straps, a cracked frame, failed side flap potentiometers, faulty microswitches, damaged pivot wiring, or a leaking hydraulic pump or cylinder. If the roof moves at all, the module is powered and communicating. Contact us before shipping and we will help you determine whether the ECU is actually the fault.\u003c\/p\u003e\n\u003ch4\u003eCan I use a used module from another Bentley instead?\u003c\/h4\u003e\n\u003cp\u003eA used module can work, but it arrives with another car's stored adaptation values and generally requires adaptation with diagnostic equipment before the roof sequences correctly. Repairing your own module avoids that step entirely.\u003c\/p\u003e\n\u003ch4\u003eWhat if my module cannot be repaired?\u003c\/h4\u003e\n\u003cp\u003eIf we determine your module is beyond economical repair, we will contact you before proceeding and explain your options.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e3W7959255B, 3W7959255, 3W7959255B009, 3W7959255A003, 3W7959255BX, 3W7 959 255 B, Bentley, Bentley Continental GTC, Continental GTC, Continental Supersports, Continental Supersports Convertible, convertible top control module, roof control module, soft top ECU, roof ECU repair, Verdecksteuergeraet, VSG, HUF, 71.083.700, Address 26, Auto Roof, module repair, mail-in repair, no coding required, plug and play, water damage repair, convertible top repair, 2006, 2007, 2008, 2009, 2010, 2011\u003c\/p\u003e","brand":"ECU Maverick","offers":[{"title":"Default Title","offer_id":48670750212337,"sku":null,"price":750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/8361\/0353\/files\/Bentley_Continental_GTC_convertible_top_control_module_3W7959255B_HUF_Verdecksteuerger_t_roof_ECU.jpg?v=1788274035","url":"https:\/\/ecumaverick.com\/products\/bentley-continental-gtc-convertible-top-control-module-repair-3w7959255b","provider":"ECU Maverick","version":"1.0","type":"link"}
