PSA EDC16C3 1.4 HDi in limp, eco mode, inject. ECU fault, uneven flow correction

**nblee** · 30th May, 2020, 10:48 AM

Hi,

The car has had immo off with your help (read here).

I shout a massive big THANK YOU to all who helped bringing my car back from the dead!!! Recycling cars like that is better for the environment than buying new electric cars

It's not 100% healthy yet. After you nicely did immo off for me, the car started! But is very underpowered, easily stalls on load, is running rough (engine is shaking, twitchy; it used to run smooth in the past: read what happened to this car before immo-off here).

I cannot rev past ~1500rpm. MFD still says "Eco mode" even after driving around.

Dashboard always has "battery not charging" lit up (though alternator works), and sometimes handbrake light (even when handbrake is off), speedo, tacho and oil temp needles do not work at all. Fuel and water temp gauges work fine. Wipers do not work, indicators work.

After immo off, I could finally clear ECU faults, and now I have two only faults (1 new):

Code:

Permanent fault. Injection ECU ECU internal fault (must be the main problem?)
P0382    Preheating relay circuit fault. Plugs permanently supplied

^ I measured continuity around disconnected glowplugs, they seem shorted out -- probably once overheated and welded with the block, so I disconnected the relay altogether.

And now I am able to rev up to 2800rpm (but still in limp), car has a bit more power, but still running rough. Live data:

Code:

measured injected flow:                 9.02 mg/impulse
cylinder injector 1 flow correction:    2.34 mg/impulse
cylinder injector 2 flow correction:   -1.48 mg/impulse
cylinder injector 3 flow correction:   -1.15 mg/impulse
cylinder injector 4 flow correction:    0.36 mg/impulse
injector 1 and 4 control error status:  no fault
injector 2 and 3 control error status:  no fault

Code:

ECU control unit condition: ECU is not locked (before immo-off it said locked)
status of the coded engine immobiliser programming: after-sales status
problems detected when transmitting the unlock code: No problem detected (before it said awaiting response from BSI)

Code:

BSI fault still remains:
Permanent fault. Absence of communication with the engine management ECU.

BSI settings -> immobiliser status:
ECM locked: Yes
transponder marker recognized: Yes
transponder key number learned: 1 (beep test works)
number of high frequency remote control commands learned: 1
BSI Matched: yes
BSI in Anti-Scanning mode: No
blank BSI: No
high frequency remote control battery: good

I hope you can help me cure it further

Thanks!!

Thanks, but it's already immo off: https://www.digital-kaos.co.uk/forum...mmo-off-please

THE PROBLEME IS NOT IN EPROM ITS IN FLASH

Thanks, but my ECU has different part numbers written on its sticker as opposed to those inside your archive:

Code:

BOSCH
0 281 010 707
020603 (this timestamp matches with 0x0007-0x000C offset bytes in my eeprom dump, your one says 011030)

1855 0525
28603

it is not a probleme just test its work ok with your car

Ok thank you, should I also write your EEPROM with immo off so it matches the rest? Also both internal and external flash memory should be written?

**Gammoudi** · 1st June, 2020, 09:21 AM

YES PROGRAM ALL

Flashed everything you gave me...

LIMP MODE IS GONE! I can rev to 4800 RPM now

THANK YOU!!! (your eeprom immo off two parts did not match inside .e2p, I fixed it and attached here)
Also Peugeot Planet 2000 now correctly accepts 8HX Euro3 ECU selection.
I also had to plug back glowplug relay to completely get out of limp mode.

Remaining problems:

No wipers, no low/high beam headlights; on dashboard speedo gauge, RPM gauge, oil temperature gauge -- these are still not working..

MFD goes black after saying ECO-MOD, even after driving the car around.
When engine is running, eventually dashboard goes completely dark (except battery light): fuel gauge stops working etc.

ECU permanent faults (never seen before):

Code:

Coded anti-start Code ADC2 reading or writing error    
CAN communication Absence of communication with the BSI ECU    
CAN communication  Engine ECU dead

BSI fault still remains:

Code:

Permanent fault. Absence of communication with the engine management ECU.

We are close to get the car 100% back on the road

YOU ADD THE REST OF YOUR EPROM ADD THE REST OF MINE IF DID NOT WORK TRY THIS ONE

**autoden** · 2nd June, 2020, 08:50 AM

Check all fuses [carfully] around battery inc wires behind battery.

**nblee** · 2nd June, 2020, 09:45 AM

Thanks Gammoudi and autoden, I shall do as you instructed when I get back to garage.

Just to re-iterate: this car had an out-of-family ECU fitted (EDC16C34), but BSI kept original. morgano said that BSI and ECU from different cars start real nightmares (how do they "poison" each other during comms?) even after putting original ECU back in..

If your suggestions don't work out, will flashing BSI be an option?

My car comes without ABS unit from factory by the way. And it's 2002, so without DPF/FAP (which was introduced not long after).

As you can see in my first post, BSI still thinks that ECU is locked (even after ECU immo off).
