Hi everyone,
So i bought another Peugeot 508 2.0 HDI SW Late 2011 recently, unseen ( i currently own a 508 HDi sedan), thought id give my self a mini project, quite the mystery box surprise. Quite a nice car actually, with the moon roof, electric tailgate, heated seats, etc.
So the issues;
1. It had a dead battery on arrival so alot of warning and flashing signs.
2. and apparently had some mechanical issue.
First thing i did was disconnect battery, and put it on charge. I did notice it is a 600CCA battery which by doing a bit of searching, it appears and under capacity or close to dead battery can cause CAN issues with the ECU's
Second thing was checking the dipstick...and finding that it is snapped...not looking good. using my dipstick from my car, found out some idiot (hopefully not a mech) had filled the oil up to the broken piece. Not looking good so far. bought some new oil and filter and drained it to find close to 10L of oil in there....INSANE haha.
Fit the battery back on and went through all the codes with diagbox, most of them are just because the battery was dead and went away. All electrics working fine, which is good. It was also low on diesel so needed to fill it a bit and prime the pump.
It started which is a good sign, although it has issues, which is where maybe some insight might help.
It currently starts but wont pass 1,500 revs and smokes a little. I expect a bit of smoke due to having 10L of oil in it and that residue will be everywhere...perhaps more than residue, yet to find out.
secondly there are some fault codes which wont disappear, they are mainly Uxxx codes that show theres a CAN issue, perhaps with battery capacity or faulty relay. The ECU codes wont clear at all which is strange.
The main codes that i think are due to what im seeing are;
B162C 11 on the BSI "fault:accesories positive relay control and status not coherent
P1727 on TCU " Fault on the actual engine torque information not received by the CAN (engine ECU)
P1605 on TCU engine torque required by the driver information not received by the CAN fault (engine ECU)
P0215 on ECU " Main Relay" Poor operation of relay, ecu is not supplied as it should be
P16A0 on ECU "Motor" detection of iol separation after cutting out....this is due to the 10L but it has been drained and correctly filled, should this not go away?
So seeing it as a potential low power or battery issue, I took the battery from my current 508 (750cca) and the engine fuse relay (hot swap able one) and put it in the car. The same codes showed up after being cleared. The only thing that i might test again, is to fully charge the 750CCA batt and try again.
I have checked all fuses on the engine relay box (i didnt check the ones over the batt though, not sure if they would be the issue), box under driver side, havent fully gotten to the BSI fuses as its a pain, taking that glovebox out...oh man...
My next attempt will be to swap the TCU as previous experience with the 307 HDi 2.0L a bad TCU causes a CAN nightmare.
I want to do a compression test to rule out complete engine failure, I am having trouble finding a correct glow plug adapter for this though. most of the sets only have an m10 x 1 or m12 x 1. These take an M8 x 1 glow plug... any ideas? or way to get an adapter cheap?
Also, what is the easiest way to test for exhaust blockage? this is in regards to the engine not revving passed 1,500 rpm. Checking diagbox the DPF sits at around 33 and when revved to 1,500 it goes to 45 ish. that shows that the DPF isnt blocked?
In regards to the relay fault codes, if i swapped the engine bay relay box and it didn't fix it, what else could it be?
And finally, any other suggestions? and am i heading in the right track? Cheers
