1.2 puretech turbo misfire under load

Twig62, did you ask about the issue at your second service?
Regarding reducing the spark plug gap that mignon mentioned. I was on a parts website looking at spark plugs and it said 2 bosch plugs were compatible with this car, the only difference was that the spark position was 5mm on one and 4mm on the other. What would using one of these over the other do to the engine?
Sorry, only just seen this. The car has not been in for its 2nd service yet however since my last post I have run it solely on Shell V Power and it may be just a coincidence but the miss fire/ hesitation hasn't occured since.

As it is an auto and it only does it when your foot is to the floor..................its not kickdown activating, or trying to activate is it? Have you tried pushing the pedal down until it reaches the kickdown switch and no further?
These are brilliant little engines.
I think a lot of the times it happens does coincide with the kick down kicking in however as I have said in the other post I have just written since I have fuelled it on Shell V Power the problem hasn't occured. These are brilliant little engines.
Hi. Sorry to resurrect and old thread.
I've just had my gearbox replaced under warranty. Apparently some form of factory defect (so they said). I told them about this misfire and they are adamant that the problem was coming from the gearbox.
Can a gearbox issue actually give off the same sensation as a misfire? (That shake/judder).

A gearbox cannot cause a misfire.I've just had my gearbox replaced under warranty. Apparently some form of factory defect (so they said). I told them about this misfire and they are adamant that the problem was coming from the gearbox.

Peoples perceptions of what faults may be.....well that ones way up in the air so there is no answer to that last question as they could perceive any problem as anything they dream up whether correct, sensible or not.
But for anyone with half a wit, no a gearbox cannot give the same sensation as a misfire.
Hi everyone. We bought a Peugeot 208 1.2 puretech (turbo) 110hp EAT6 Gt Line, year 2016. Yesterday i realised a misfire/hesitation. I was driving with 100-110km/h speed with cruise control on highway, gear was at 6th speed. I changed my speed to 145km/h on cruise control. The car changed the gear to 5th speed and started accerelating. While accerelating car hesitated for one or two seconds and it continued accerelating. I tried it by pushing throttle softly, it made it again. I pushed the throttle full down, shift changed to 3th speed speed increased up to 175-180km/h and there was no hesitation or misfire. I was using Shell V power. I don't know the exact reason. Maybe it's about the fuel or maybe depends on which speed i'm driving; it's making when accerelating at 5th speed. I also have a Citroen Ds3 1.6 Thp, it's making same hesitation when accerelating with cruise control on 5th or 6th speed. I guess they are same engines; 1.2 thp and 1.6 thp, only difference is piston numbers.
Hey, just for info for anyone seeing this kind of thing,
ours (C4, 1.2 puretech 130, 2.5 years old) did this, but it did set the engine management light off.
Took it in to Citroen under warranty (which they did everything to wiggle out of, but finally accepted!), at which point they ran diagnostics to check the fault codes, and found code P1032 whatever that means.
Anyway, they freaked out because there is a Citroen technical service bulletin about this and various other fault codes, it is number VF73AHNYMGJ641042 - has a set of things they check which starts off with replace the oil and filter, then goes down to clean the engine and replace various turbo & engine parts and finally on the list ends at 'replace engine'.
Ours has gone through new oil and filter (light came on again), and is currently in the garage going through the rest of the process. Says the problem is 'self-ignition before spark (rumble)' on the service bulletin.

That's your VIN btw, not the service bulletin #. You might want to remove it.Hi again... Is there any update about this misfire/hesitation issue? Did anyone find the exact reason for this?
I took my car to Peugeot service; they made some firmware/software updates, they checked everything, but the engine still goes on misfiring while accelerating. They told me to come back if happens again, they will check carbon build up on the intake valves. (I think it's too early for a 33.000km car, but can't be sure)

Hi JoeJoeJoe, how did this one end up for you? I sent mine into garage with P1032/1033 codes and funnily enough so far they only want to change oil and filter. ours (C4, 1.2 puretech 130, 2.5 years old) did this, but it did set the engine management light off.

The 1.2 Puretech engine suffers from LSPI (Low Speed Pre-Ignition), a problem that has reared it's head since the introduction of small, turbochared direct injection engines. Citroen/Peugeot know this but have kept the problem very quiet. The procedure that joejoejoe mentioned starts with an oil change since LSPI is known to be exacerbated by certain oil additives and it's the cheapest and quickest fix.I took my car to Peugeot service; they made some firmware/software updates, they checked everything, but the engine still goes on misfiring while accelerating.

What is the OEM part number? The ZR6 plug seems to be the recommend part by several different online parts stores, but unfortunately there doesn't appear to be an official online Bosch catalogue any more which is pretty poor.
The spark plugs aren't the cause of LSPI in any case, but obviously the correct grade should be fitted.

Thanks for the replyThe spark plugs aren't the cause of LSPI in any case, but obviously the correct grade should be fitted.
98 299 301 80 is the current Peugeot part number. According to auto doc app this relates to bosch 0 242 145 535 which is the zr5 plug.
Everywhere else lists only the ZR6 but knowing how the plugs can be fragile on these I want to make sure the right ones are fitted.
We use momentum 99 to try and prevent pre det.

Seems like the majority of places are showing ZR5 as the equivalent, but also a few references to ZR6 and I also found other people confused by this on different forums so nothing conclusive unfortunately. I wonder if Bosch changed their recommended part at some point. Like you I would be tempted to go for the colder plug in this case.98 299 301 80 is the current Peugeot part number.

The problem is pre-ignition rather than detonation (no such thing as 'pre det'). Higher octane fuels appear to reduce the incidence of LSPI, though probably due to secondary effects such as flame speed and the amount of volatiles in the blend. The one thing that is definite is that the engine oil plays a significant roll, low calcium oils must be used in these engines.Gassing Station | Engines & Drivetrain | Top of Page | What's New | My Stuff
