Tip 2

AL4 Pressure Regulation Fault ( Check and repair)

Model: 206, 306, 307, 406 with AL4 Automatic Transmission.
And a lot of other Citroen Cars , and other Renault cars

Symptoms
Flashing of the snow or sports light or Automatic Transmission Fault on display.

In most cases the transmission will go into the downgraded mode, or limp home. In this mode the transmission is locked in third speed to enable to continue the operation of the vehicle. This is reported by some drivers as a loss of power. The downgraded mode can be preceded by some very harsh up or down shifts. After stopping and restarting the engine, the transmission will usually return to normal operation.

Most of the time the problem appears at unpredictable intervals. Some owners experience incidences on a daily basis and others may have weeks of trouble free operation between incidents. Normally the malfunction lasts only for short periods, from a few seconds to a minute or two.

The following fault code is logged in the transmission ECU:
"Intermittent fault. Pressure regulation fault, recommendation/variation"

Cause
The pressure regulation fault code is triggered when the ECU senses a difference between the calculated pressure and the actual line pressure in the transmission. The pressure difference is caused by internal leakage. Internal leaks can be caused by mechanical wear, a leak between valve body and transmission casing, incorrect adjustment of the manual valve index spring. The most common cause however is the pressure regulation solenoid valve.
Diagnosis.
The diagnosis is not straightforward, several operations are required to eliminate possibilities.

Transmission fluid
Check the fluid level in the transmission and rectify if as required. Low or high fluid levels are equally harmfull.
Save some of the drained fluid in a clean container for examination.
The transmission may need to be overhauled or replaced if:
The fluid sample is black and smells burnt, contains metal particles, plastic particles or friction material.
New fluid is transparent. Fluid drained from a transmission that has been in operation for some time is usually dark in colour and lacks transparency, this is acceptable and not necessarily an indication of an internal fault. Caution is to be exercised with the fluid assessment.

Pressure sensor
With help of the diagnostic computer check the transmission line pressure.
The following parameters are expected.
At idle in N: 2,4 - 2,8 bars.
At idle in D: 2,8 - 3,1 bars.
Under full load 2200 rpm: 11,3 - 11,7 bars.
If there is no change in pressures, test the sensor and sensor supply.
If a sensor is faulty a constant pressure of 6,5 bars is maintained by the system. This would also mean that the transmision would be in Limp Home Mode and that the fault is permanent. Since the problem usually is intermittent the pressure readings will check out OK most of the time. If no other problems have been found so far, continue with section 3.

Solenoid Valves
Replace the pressure regulation valve and the converter lock-up valves.
Make sure the 2 seals behind the valve body are correctly fitted. If necessary replace the seals.
Tension the valve body bolts to 8 NM.
After fitting the valve body adjust the selector index spring
Adjust the multi-function switch.
Before fitting the pan ensure the 2 magnets are present.
Fill the transmission with new fluid and adjust the level.
Update the transmission ECU software. The older software versions are not compatible with the new Borg Warner valves.
The operations autlined obove will in most cases resolve the pressure regulation problem. If the problem can't be resolved follow step 4 or 5.

Valve Body
Replace the valve body
Transmission
Replace or overhaul the transmission.


Important reminders

1-Only use genuine Peugeot transmission fluid.
2-The fluid level must be correct.
3-The correct adjustment of the manual valve index spring is very important.
4-Adjust the multi-function switch after the valve adjustment.
5-Cleanliness is absolutely essential when working on the transmission.

Tip 3

Replace air filter on Peugeot 308, 307 and Citroen C4

Tip 4
Anti Pollution Fault.

There is large numbers of inquiries online with regards to the anti pollution fault . This usually means a warning saying - Anti Pollution System faulty - is showing on the display. Quite often the engine warning light illuminates at the same time. It is also possible there are no noticable symptons. In short, this warning indicates the presence of a fault, either in the engine management system or the transmission mangagement system, that affects the vehicle's emissions.
Any malfunction like a slight misfire, fuel mixture too rich or lean over a priod of time, or even a problem in the transmission can trigger this warning. In every case without exception there is only one step that can be taken at the earliest conveniece. Take the care to a workshop
- DO NOT ASK PEUGEOTLOGIC WHY THIS IS HAPPENING - If you don't wish or can't go to a Peugeot Service Centre then you can go to a independent workshop as long as they have a suitable diagnostic scan tool. A scan of all the systems will soon point in the directon of the problem. The cause can be in the transmission or then engine management system, more often in the engine side. Reading the diagnostic trouble codes (DTC) is always the essential first step of a diagnostic procedure and will often lead to a quick resolution. However a resolution is not always instantanious and further testing may be required. The onboard diagnostic system can never give an absolute answer, it will point the technician in the direction and he has hopefully the experience and the skills to drill down to the root of the problem.
Tip 5
The new Diagnostics tool for diagbox7.65

In this video you can learn the differnce between the old diagnostics tool of pp2000 and lexia and the new one which works with diagbox v7.65

Tip 6
Procedure to upgrade to Diagbox 7.77

Procedures to upgrade to DiagBox
v7.77 (if you have upgraded to 7.76, it worked from 7.74>7.75>7.76>7.77)

Please notice that this is intended for educational purposes and that you perform any or all the below procedures at your own risk. I hold no responsibility for any issue you may face.

Procedure 1 (From the internet):
1- Go to C:\AWRoot\bin\fi\ and create another copy of cashe folder naming it cashe.Org
2- Run DiagBox and click on upgrade, after successful download close the application.
3- Run DiagBox it will start the upgrade process and when run for the first time, it will give 6 or 7 error message, keep klicking ok until DiagBox closes down.
4- Go back to C:\AWRoot\bin\fi\ and delete the folder cashe and rename cashe.org to cashe
5- Run DiagBox and it will run successfully.

Procedure 2 (Local upgrade):
1- Go to C:\AWRoot\bin\fi\ and create another copy of cashe folder naming it cashe.Org
2- Download the attached file, Expand it and copy the contents of the updt_77 to C:\AWRoot\dtwr\updt\ directly replacing and overwriting existing files and folders
3- Run DiagBox, it will start the upgrade process, when it finishes successfully click ok, it run for the first time and will give 6 or 7 error message, keep klicking ok until DiagBox closes down.
4- Go back to C:\AWRoot\bin\fi\ and delete the folder cashe and rename cashe.org to cashe
5- Run DiagBox and it will run successfully.

If you like to try newer file versions:
3- When you receive the first error message in point 3, DiagBox creates 28 new files in the cashe folder copy this folder into a folder named cashe.cpy, because the contents of the original cashe folder get deleted after the crash.
Continue to click on the error message until diagBox closes.
4- Now, copy into the (empty) cashe folder the 13 files that start with fr.actia.AWF.xxxxxxx.dll from the cashe.org and all other files from cashe.cpy.
5- Run DiagBox and it will run successfully.
