2008 308 1.6 with P1338, P1339 error codes

Hello,

I have recently acquired a 2008 model 308 with unknown history.
It has high mileage - 218,000 kms. (135k miles).

When under load (driving up a hill) the car gives the misleading "Depollution System failure".
Sometimes at that moment it will drop to running on 3 cylinders. either cylinder 2 or cylinder 3.

Reading off the error code, it is either P1338 or P1339.
I reset it, and then the problem won't come back again until it is under load. It seems fairly consistent.
We have had all plugs and coil packs checked. Also swapped them around, and it does not follow the coil packs.

Work done so far to "hopefully" remove the problem.
  • fixed one coil pack
  • new fuel filter
  • replaced the timing chain (guides, sprockets, chain) - cam locks, flywheel lock - 6 hours
  • stripped and cleaned the air intake manifold ports around the valves - 6 hours
The car runs so much better after this change :) †† see 308 1.6T 2008 - Procedure for Air Intake Valve Cleaning

Questions:
- Do people think it is
- a sensor, (camshaft, other)
- a solenoid (VTi ? )
- fuel injectors
- fuel pump
- ECU ?

Thanks in advance

I have just put in a bottle of fuel injector cleaner into the tank. (Not a brand recommendation .. stripped brand.. Only one they sold :) )

So far so good.
The car was cold (13 deg here in sydney).
I drove it around and it warmed up. fault code kept coming. Stop, reset, drive.. stop.. thn after about 10 minutes.. nothing. No lagging, no acceleration studder. So I pushed it .. slow, fast, under load.. nothing.

I'll check it again when its cold. See if it's a cold / warm thing, but it's never driven better since I have had it.

I'm super sceptical about these cleaners.
This was a good brief read on the science ..

This isbthe procedure and best video I have found re replacing the timing chain.
This mini motor is identical to the 308 1.6 EP6DT engine. (Turbo) only has one banks sprocket. Not two. ..



If you're in Sydney and new to borrow my timing camnlocks. Message me.

Hi mate,
I have a few of the same issues as you have.... our Peugeot 308 is also a 2008 with 142,000 km on it.I have trawled all the forums and looked at many YouTube videos on this engine and it's problems. I finally relented and took the car to Peugeot who still haven't managed to sort it out. They have come back to me and told me they think there is a dry soldered joint in the ECU, which I think is them grasping at straws (it is around $1000-$1800 for an ECU fix/replace!!).

I have done the following:
-Replaced all coils
-Replaced all spark plugs
-Replaced the heater matrix (unrelated)
-Replaced the thermostat housing (probably unrelated, but early on the fan was running I considered it was an issue)
-Removed, cleaned, and tested the VVTI solenoids
-Replaced one camshaft position sensor (that fault is still up so it may be an issue and I will replace the other)
-Checked for timing chain rattles/noises

Peugeot have done the following:
-Cleaned the carbon deposits out of the intake
-Removed the fuel tank and replaced a filter in there
-Checked the number one cylinder fuel injector
-(Apparently changed the spark plugs again)
-Replaced the rocker cover gasket as there were oil weeps, including into the number one spark plug chamber
-Told me the ECU is probably at fault because I used after market coil packs.......

Pretty sick of the whole thing really, especially now as I have to go and have a chat about the $2300 bill and pick up a car that really is no better than when I took it to them 9 working days ago:cry:

Interestingly, the car runs great when warming up, and it is almost like the engine run parameter changes when it is up to temp (90 degrees) and it starts to misfire on cylinder 4 (closest to driver's side). If you drive it down the highway at 100km/h it seems to behave OK until you slow down for the traffic lights etc. then it goes into a rough running/misfire situation.

Cheers, Mick

Identical Mick. 90 deg..
I use a generic OBD2 scanner to reset the codes.
If that is done and it gets to 90 deg, I can kind of have great run at full torque, load, speed, etc.

But starting cold, it seems to appear real fast.

My next line of attack is
  • if ordered a replacement rocket cover (the one it has has "repairs" .. Which I don't like.
  • ordered a lexia3 cable and have peugeot planet 2000 on standby.
  • will look into fuel pressure % low or high.
Going to use some tech to log all streamed data to a computer. I'll post about that after I do it.
- when the rocket cover arrives I will test and clean the 4 injectors.

There is a company in the UK that will test and program the ECU FOR £250. But I'm in Australia.

I’m in Tasmania👍 Am currently negotiating with Peugeot here as they are sure the ECU is at fault. They want to send it away and get it checked/repaired. I’m not convinced but if they can guarantee me this is the problem hopefully it will be sorted one way or the other. Will keep you posted! PS have had rocker cover gasket replaced with no change☹

As suspected. No compression issues on all 4 cylinders.

Numbers are in reverse on my card..

Cyl 4: 1050 kPa ( closest to timing chain)
Cyl 3: 1100 kPa
Cyl 2: 1050 kPa
Cyl 1: 1050 kPa

So there is no issue there.

... next issue resolution .. telemetry..

@Torque69 On the air intake (under the filter box) there is a sensor. I have an oscilloscope so I'm going to look at all sensors this weekend.

89171


Then these are the other sensors I'll check.

Cam inlet and cam exhaust.. o2 sensor on exhaust, and the other sensor inline after the intercooler.

I have been working on some better data logging.i have now written some software to collect the data to some dashboards.

This shows me that the short term fuel trim is way off. I believe that is meant to stay within +/- 3%

It takes the car a little while to come good.. 20 minutes. At which point it runs nice. That's the 16:52 time position.. it settled after that.

( no peugeot planet, just OBD2 and my software )

Hi all, I have just got ours back from the “Peugeot Specialists” after 40 days and they tell me they don’t know what the issue is! I paid $3000 to have it back doing exactly what it was doing when I took it in. Their next guess is either oval bore or stuck oil rings in number 4 cylinder (apparently the one on the left looking at the engine). I have now paid more than the car is worth to have a specialist repairer tell me that a 1600cc engine has beaten them. My advice is sell what you have before it becomes junk like ours and keep away from Peugeots (or European cars!).... over and out

Hi all, so I now have some really good news

The last fix attempt pre this posting was replacing the exhaust manifold sensor.

It didn't improve it, but the previous one was faulty because the short and long fuel trims improved afterwards.

I replaced too the crankshaft sensor but that didn't fix it either.

I ordered an AUD $20 crankshaft sensor from Alibaba in August but because of covid if arrived yesterday Nov 10.

AU $18.79 | Crankshaft position sensor for Peugeot 207CC 308SW 308 3008 RCZ Citroen DS5 C4 BMW MINI 1920LR/13627561753

My dad installed it today.. and it's fixed. No more errors.

Geez that was a long fix.

So it was a timing issue after all.

Suggest if you've got this problem .. replace the two sensors first AUD $40 plus labour.

Then explore tining chain and fuel mishaps.

Salut à tous, j'ai maintenant une très bonne nouvelle

La dernière tentative de réparation avant cette publication remplaçait le capteur du collecteur d'échappement.

Il ne l'améliorait pas, mais le précédent était défectueux car les réglages de carburant courts et longs se sont améliorés par la suite.

J'ai également remplacé le capteur de vilebrequin mais cela n'a pas résolu le problème non plus.

J'ai commandé un capteur de vilebrequin de 20 AUD à Alibaba en août, mais à cause de la covid, il est arrivé hier le 10 novembre.

18,79 $ AU | Capteur de position de vilebrequin pour Peugeot 207CC 308SW 308 3008 RCZ Citroen DS5 C4 BMW MINI 1920LR/13627561753

Mon père l'a installé aujourd'hui... et c'est réparé. Plus d'erreurs.

Bon sang, c'était une longue correction.

C'était donc une question de timing après tout.

Suggérez si vous avez ce problème .. remplacez les deux capteurs d'abord 40 AUD plus la main-d'œuvre.

Ensuite, explorez les accidents de chaîne et de carburant.

bonjour j'ai exactement le même problème que vous qu'elle sont les sondes que vous avez changer
