Hello everyone;

Friends, about a month ago, I bought the vehicle in the topic title. My car is at 87500 kilometers. But since I bought it, the problems of the car have overwhelmed me. I will share the error codes and their names below. Please help me on the path to follow. I love my car, but I can't use it with pleasure.

NFU - MOTRONIC MP 7.4.4 - 1.6l

P0420 - Catalyst system efficiency below threshold (Bank 1)
P1324 - Compound ignition phase register
P0336 - Stage/efficiency in crankshaft A position sensor circuit

THE TRANSMISSION - AL4

No Error Code - Missing in transmission
No Error Code - Engine torque ( From CAN)
No Error Code - Pressure regulation; faulty signal

Also, I was on the road yesterday, when I was driving in Istanbul after work, because the gasket of the crank pulley fell off, thank goodness a mechanic helped me. We bought a new crank pulley and installed it, now there is no problem.

The thing that bothers me the most is that when the vehicle is in 4th gear, it constantly misfires at constant throttle at 2000-2500 rpm, at high rpm. There is no problem, but when falling from high speed to 2000-2500 revs again, it also makes a separate misfire. The spark plug was changed, the problem still persists. Also, there is no reaction on the manual side of the triptonic, pushing back and forth does not give any reaction.

I am waiting for your help. Many thanks in advance...Smile

Hello teacher. Good luck with your vehicle. I hope you use it safely. The source of the first three problems can be the ignition system related to the fuel that is not lit and the catalyst failure. First, replace the crankshaft sensor and check its sockets. Depending on this, the other two errors may go away. As for the gearbox, it's probably like the gearbox brain is faulty because it doesn't give the error codes. there is an error but what? First of all, I would say find a good Peugeot master and deal with engine malfunctions. The second job is the gearbox because it can be a bit costly job. The average cost for the gearbox may be between 2000-15000 TL.
