Peugeot 508 RXH 2.0 BlueHDI 180 - U1318 83 and 86

[K82]

Hi,

I have a problem with Peugeot 508 RX 2.0 BlueHDI 180 EAT 6. The car sometimes has full power and sometimes it doesn't. I have two errors in ECU:
U1318 86
U1318 83

I cleaned all fuses and electrical connectors in BSM, BSI and ECU.

Interestingly, the gas pedal sometimes works hard (it is hard to press) and other times works slightly.

In Diagbox and Car Scanner (with ELM) the gas pedal has a discrepancy between signal A and B. the difference is 3% but not always.

I have new components:
1. Turbo solenoid valve
2. EGR
3. MAF
4. Negative terminal with charging monitoring module
5. Overflow pipes for injectors
6. Thermostat
7. Two tensioners and a multi-ribbed belt
8. Fuel pressure regulator on the CR pump
9. Throttle plate

All original parts!

Why there is no power?

From your descriptions I would be suspicious of the throttle pedal sensor, have you looked at that?

The problem is that the car can drive well. It drives well after disconnecting the battery. Day / several days...

How to find the cause of errors? Are you sure it's the throttle pedal sensor?
