Tailgate (hatchback) does not open

With this kind of repair, the customer complained that the tailgate or hatchback of his Seat Ateca 1.4 l 16 V TSI (110 KW) (model years from 2016, engine code CZEA, VIN no. from VSS___5F_H6505463 to 514221 and VSS___5F_J6500001 to 500001) could not be opened electrically or, if at all, only sporadically.

Troubleshooting
In order to exclude other possible causes of malfunction, electrical and mechanical system tests (in accordance with vehicle manufacturer specifications) and also a fault code query using a suitable diagnostic unit should be carried out.

The following error codes can be stored in the control unit:

• 01148 / 047B Engine for tailgate/hatchback locking-V120
• 01483 / 05CB Remote control for tailgate/hatchback locking
• 00896 / 0380 Tailgate/hatchback locking mechanism-F256

The solution
In this case, the cause of the above-mentioned problem is the electronic control unit for the tailgate/hatchback drive. The control unit must be replaced by a new one. The control unit is located behind the rear bumper, on the right above the trailer coupling attachment.

Repair tip
The vehicle manufacturer has introduced a new service regarding this, which, when successfully carried out, is documented by means of a sticker placed in the spare wheel recess area. An entry is also made in the service booklet. First of all, the production date of the control unit for the tailgate/hatchback drive should be checked. If the date is between 11.08.2016 and 20.09.2016, the control unit can be renewed via the service measure if necessary. (OE article number: 3G0 962 243 A)
