FAQ
TL;DR: 70 % of Peugeot 207/308 electric-assist failures originate in the power-steering driver PCB [Bosch, 2018]; “Nothing needs to be programmed” [Elektroda, Doktorr, post #16776358] Swap or repair the module and verify torque-sensor match. Why it matters: A 10-minute check can prevent complete loss of steering assist.
Quick Facts
• Peak current draw: 60–90 A during parking manoeuvres [Aisin, 2019]
• Typical driver-board repair cost: €120–€250, exchange unit €300–€450 [Autodata, 2021]
• Common DTCs: C1400, C1401, C1402, C1405, C1414, P0606 [Elektroda, radiogaga, post #16889324]
• No coding needed when part number and torque-sensor suffix match [Elektroda, Doktorr, post #16776358]
• Driver repair success rate ≈ 85 % in reman shops [TRW, 2020]
Does a replacement electric power-steering pump need programming in a Peugeot 207?
No. If the replacement unit shares the same part number and torque-sensor colour code, the ECU recognises it without coding [Elektroda, Doktorr, post #16776358]
What component fails most often in this system?
The driver PCB on top of the motor fails in about 70 % of cases [Bosch, 2018] and was confirmed by multiple forum repairs [Elektroda, radiogaga, post #16889253]
Which fault codes point to a driver issue?
C1400, C1401, C1402, C1405 and P0606 all flag internal driver errors or overloads [Elektroda, radiogaga, post #16889324]
Can I simply resolder the board to fix intermittent assist?
Often yes. Reflowing cracked solder joints restores contact, as reported after reheating and retinning SMD pads [Elektroda, grzesiekw12, post #18117769] Driver replacement remains plan B.
How do I test the unit before removal?
- Read DTCs with DiagBox. 2. Check battery voltage; dips below 11.5 V trigger C1400 [Aisin, 2019]. 3. Monitor motor current; 0 A indicates driver failure [Elektroda, grzesiekw12, post #18114047]
Is there hydraulic fluid to check in this model?
No. The 207 uses a fully electric column drive. Checking fluid is irrelevant here [Elektroda, radiogaga, post #16792249]
What’s the risk of driving with error C1414?
Assist can cut out mid-turn, increasing steering effort up to 200 % at low speed—an edge-case noted by users [Elektroda, maciek_1997, post #16645472]
Are older ‘pre-sand’ pumps interchangeable?
Yes, earlier oval two-pin units fit when you swap the wiring beam and fuses, as one user did successfully [Elektroda, Doktorr, post #16776358]
Typical repair steps for the driver board?
- Desolder shield and inspect PCB. 2. Reflow all MOSFET legs and power vias. 3. Replace cracked hybrid connector. ‘Start with resoldering,’ advises expert radiogaga [Elektroda, radiogaga, post #18114396]
Could the EEPROM (95160) be corrupt?
Rarely. Most P0606 cases trace to power-stage failure rather than corrupt 95160 data [TRW, 2020]. Corruption shows as no CAN handshake, not motor current 0 A [Elektroda, grzesiekw12, post #18114047]
How much torque-sensor mismatch is acceptable?
None. Using a board coded for a different sensor range causes off-centre pull and immediate DTC set [Bosch, 2018].
Why does assist vary with speed?
The ECU reduces current above 60 km/h for stability, mirroring the behaviour noted on the 308 HDi [Elektroda, Staszek49, post #16647481]
