Morning
Went to a Peugeot authorised SC early this morning to see the progress on myPeugeot308 getting things fixed up as further described hereinafter.
Fortunately I was lucky to meet both, the Service Manager and the chief mechanics to confirm my 'allegations' on what I have been writing true.
I was 'honoured' to be taken for a tour in the fully packed workshop with over 30 Peugeots - either being serviced, repaired or just waiting for their turns. Mine was still in the Q even after day 8. I don't want to jump Q since nothing to complain for the delay as it looks like this particular workshop is full - where most Peugeot owners send their cars to get service/repair done here.
To my surprise, the truth was beyond my imagination. There was a worse case when the valve timing was totally out of synchronisation. In such case the piston hit the valves and damaging all of them! A few cars lying there with their engine on the floor waiting for the spare parts to arrive.
I left the SC and let them had a discussion among themselves and decide what to do on my car after 8 days lying there.
Afternoon
During lunch hour, the Service Manager at the authorised SC called me up. My place is located about 30km down south. I took a public transport and decided to take the car home because I knew myPeugeot308 turn would not be possible before end of February. Too many cars are already in the 'operating hall' while a few more still waiting for their turns.
I don't want myPeugeot308 to be exposed under intense tropical sun-rays and rain for another week or 2. On top of that I just want them to practise on other cars first; then we decided roughly the date for myPeugeot308 - subject to confirmation though...

Probably Peugeot/PSA has already realised and now I'm telling that certain batches if not all Peugeot THP engines have a serious design fault that timing chain pinion may slip and hence the engine loses its valve [and ignition?] timing.
Why Peugeot don't tell the truth?
Technically speaking, by looking at the design [pls refer to the illustration below]...
The timing chain pinion does not have a key and slot or any other way of locking into a fix position to the crankshaft except the pulley hub and bolt. You don't need to have a PhD or a Master Degree in mechanical engineering to figure out what would happen if the bolt become loose or elongated.Now, if "mysteriously" it does happen, there would be subsequent angular displacement for the relative position of the camshafts to the crankshaft hence altering timing. Now I would say it is the design fault. Peugeot should have recalled every effected engine and fix it. Unfortunately it did not happen and Peugeot is gambling with the aftermath.
How Peugeot/PSA should have fixed it?
Simple answer is to "redesign" the whole pulley hub, timing pinion and chain assembly. Anyway, I think PSA has already done so, after all they are not a bunch of idiots, are they?
Now, are you worried?
Well, when buying stops, worry can too!

so, whats d outcome of your little tour there bro? any promising update?
updated already for the afternoon episode....
to be continued....
awaiting your updates with batted breath.....my knocking issue is back...this after 2 services where the SC changed and recalibrated a ton of stuff
:(
I was told the knocking issue can be resolved by simply re gaping the spark plugs. True or false?
Probably it could be one of the solutions for normal knocking. I don't know, but Super knocking is different and very complicated in nature due to many possible reasons such as faulty HPFP, mulfunctioned solenoid, dirty manifolds and valves and of course slipped timing chain sproket and defective cylinder head... etc.
Technically, the culprit is the design fault. Whot do u think?
im more inclined towards uncle's observations....the SC have changed my spark plugs, calibrated the timing chain and finally changed the timing chain and a whole lotsa other stuff...still the knocking is there...its a design fault and the manufacturer knows it....just that they are trying to plead ignorance and hope the issue will fade away or at least till the car's warranty expires....i intend to document all this down in detail and whack them shud they turn around after warranty and screw me with a hefty bill
wud advise all other owners to do likewise :)
100% agreed. It's THE design fault. Changing timing chain and whats not is only temporary solution. As I pointed out, PSA Peugeot aught to come out with the new design to make sure timing sprocket or pinion is locked in place.
This is a very big issue. Anyone amongst us is a lawyer?. We need a legal advisor or two to assist us.
A friend has commented but later deleted. Anyway I could retrieve it and find out that he is selling his 308 THP...
Well, that is the most logical choice, but my advice ... Never sell the car to a friend, a relative or anyone knows you. If you do that will be the beginning to end your relationship.
Cheers...
All thp engines are faulty. I fix my engine on 2000 khm and now has 12000khm and needs all the shits to be replace , timming chain ,tensioner,pulleys,hub,......... Because i have a. Serious power loss and no check engine light come up... Stupid company stupid cars,,, whe n the timming is wrong how can i wait 1-2 months the parts to arrived? So if i break the engine hows fault is? They don't have parts,they fix again and again the same issue,you have to wait 2 months,and they don't give you spare car to not destroy yours.. rcz thp 200
