Citroën DS7 Crossback Fault Codes

About the DS7 Crossback

The DS 7 Crossback was first introduced in 2017. Since then, there has been only a single generation to hit the markets. The model was later renamed with the Crossback badge being dropped completely.

It is currently offered in both petrol and diesel, as well as various plug-in hybrid versions.

The crossover model marks the first SUV to be released for the European market, although not the first SUV from the premium French carmaker.

In terms of the DS lineup, the 7 sits above the DS 6 and DS 9. Competition from other manufacturers includes the Volvo XC40 and Jaguar E-Pace.

One of the most common fault codes the DS 7 faces is P0101, which represents a MAF sensor circuit issue. This can be a pretty serious issue as it can put the vehicle into limp mode.

Despite the code indicating an issue with the MAF sensor, some owners have found success in cleaning or replacing both this sensor along with the manifold absolute pressure (MAP) sensor. Owners have also found success by replacing the air filter and fixing any leaks in the intake system.

Alongside this, fault code P0106 is another fairly common problem. This code indicates that there is a problem with the MAP sensor. If both of these codes are logged, it is likely that the cause of the problem is the MAP sensor or its circuit.

The next most common problem the DS 7 faces is P0410, which indicates that there is a malfunction with the secondary air injection system.

This system works in conjunction with the catalytic converter to reduce emissions, particularly in cold environments. Because of this, it can be hard to pick up an issue with the system.

Owners have reported that the most common cause of the issue is a failed AIR pump.
