Carrying out a small scale car repairs on your own vehicle may take little more than a bit of research and the purchasing of new and used car parts online. The task facing BMW China is significant larger, as they have had to recall as many as 1,694 of its 7-series sedans in China in order to fix a problem that has been occurring with the gas pipes.

This news was announced by the General Administration of Quality Supervision, Inspection and Quarantine on Friday. The set date of recollection is June 25 and will come at no cost to the customer. The administration said in a statement that “gas pipes in these cars could be disconnected due to substandard production materials, which could lead to engine failure”

BMW now faces the long job of remodelling the gas pipes and replaceing the gas tanks for over a thousand vehicles.
