Hello, today I’ve received notification from my car that the engine is at fault and it should be taken to the workshop.
So it went
Service told that it’s related to leaking top engine cover (Cylinder Head Cover) and it’s happening in 1.6 Petrols.
I have currently driven 68000km.
For everyone else - to notice:
around 2 weeks ago I’ve noticed very loud, squeeky noise only at the morning from area between the engine and gearbox so I reported i to the workshop it stopped after driving around 200m everytime and didn’t come back the same day
they asked me to check the engine Top Cylinder Cover where I’ve noticed the leaking so the issue was known to them.
after another week I had a notification that the engine oil level is to low so I’ve added 500ml 0W30 engine oil specified for the car
after another 6 days today’s notification about engine failure has appeared - they also predicted that it will happen.
Workshop told me that that’s how this issue is progressing trough time so replacement of the top engine cover (Cylinder Head Cover) should fix the issue which is going to be fixed under warranty.
Same happened to me at 50000 also 1.6 puretech 180. But I had ti wait 3 months for the part to come, there was a global issue with supplies. Since it is out of warranty they will charge 500 euros. I haven’t had engine light on, but red blinking oil light and then added 0,5 L of oil and it stopped blinking, then they noticed crack on the plastics on the top of the engine cover with oil around. I had once rattle sound but stopped after a minute and never comeback. I have appointment on 02.01.2026 for this to be fixed and I also need to ask them why am I losing coolant so quickly but temperature is always fine.
Yes, the engine breather valve is damaged – these are the symptoms. The engine cover needs to be replaced. Part number 9818425480.
Can be repaired without replacing the cover. Repair kits are available. Costs 300 vs. 30 EUR
Just to add that first symptom was blinking red oil lamp, and drove like this from work to home (10 km distance) before I added 0,5L of oil. I was also confused there was no message on the dash written “oil level low” nor there is blinking red oil lamp in the manual, just fixed red, and newer Peugeot/Citroëns have no orange oil lamp blinking or fixed at all. And yes dipstick showed levels a bit under minimum, I just hope I didn’t screw my cylinders too much.
I am also loosing antifreeze, toped up maybe 3 weeks ago to the max level, and it is already dropped by 1/4. It is unbelievable for the DS brand who is pretend to be a premium, after 50.000 kilometers car is dying
I drove a C5A 1.6 PT 180HP over 100,000 km, and everything, including the coolant and oil, was fine. I didn’t even replace the engine cover. This engine is relatively unreliable, so yours must be a rare case.
I am visiting DS garage on 2nd of January, so far oil is leaking from the cylinder top cover, coolant is decreasing continuously somewhere since I topped up a month a go and it’s already from MAX dropped to the middle, and a new one is washing fluid leaking, I noticed huge amount of fluid dropping under the passenger front bumper just after a drive, it smells like washer fluid and noticed under the bonnet in the right side if the wall where goes installation from the washer is wet
Add 5mm above the maximum level two/three more times and it’ll be fine. Apparently, there’s still some air in the system. Also, fluid loss occurs periodically. This is normal - read the manual. This is not a malfunction.
They are changing cylinder head cover right now, and for coolant they said that this 1.6 petrol is consuming a lot of it, so there is no issue, I just need to top up every time it’s at MIN.
