DS7 cam drives

[Dagman]

Hi everyone, new to the forum. I'm probably asking an age old thing here but... can anyone provide a full list of DS7 Crossback engine cam/timing drives? say from 2017 onwards, I am sceptical about the 1.5 engine power (maybe too much internet/youtube conclusions but I'm happy to be corrected!) so bearing that in mind a 2.0 diesel? I want to avoid 7mm chain and wetbelt timing drives but find it hard to get info. Just want a good old reliable dry timing belt (cheaper to change) or 8mm timing chain engine. Thanks in advance.

Here is some info to get you started and I'm sure there is more around but you have to dig for it:

Thanks mickthemaverick, I've read the posts you suggested.I have dug and looked for weeks now, when I've shown interest in cars at dealers they seem open to tell me stuff but the info is limited and I don't want to travel miles to look at one to find the dreaded wet belt or 7mm chain. It may seem fussy but I can only just afford one of these cars (wanted one for ages) and a disaster with the engine is unthinkable. If only there was a list to tell me which to avoid. Thanks again, if anyone has any info that would be great.

Stellantis have recently extended the 1.5 hdi engine warranty to 10 years or 150k miles if sooner. As a result if you get a car that has been fully serviced by a dealer and you continue to do this, you should benefit from this. The service record must be checked before buying to ensure you would be covered. The 8 mm chain I think came in about 1 or 2 years ago. https://www.media.stellantis.com/uk-en/ ... -consumers

Petrol engine wise, I think it is the 1.2 Puretech that has the wet belt, the 1.6 may not but I am not 100% certain.

When looking at a car you need to check its build date and not when it was registered for the number plate. There have been cases on here where cars have been 1 or 2 years old before being registered. You can do a check by looking at the tyre pressure sticker and noting the rpo number which can be translated to give the build day. This might help viewtopic.php?t=74163

Thanks PaulC5. I've seen instances as you say, where cars have not had proof of service and therefore Stellantis have rejected them. A detail probably not expected and I think a sneaky get-out clause, the honest thing would be a recall regardless maybe as a safety aspect? Unless a correctly done service book is provided I will steer clear. Meanwhile I will keep looking and probing but I'm apprehensive. I must also look around this site and see if a 1.5 is adequate for the DS7. Cheers

A stamped service book does not prove anything, you would need receipts of services detailing what was done and which oils were used. It would be best if done at a main dealer. The oil spec for the 1.5 hdi was changed at the end of 2023 to help the cam shaft chain so if the oil put in at the annual services was not the correct one that could count against any warranty claim. Due to the potential cam shaft chain problems I have continued to have our 308 dealer serviced each year when usually I have done diy servicing once out of warranty.

On the 1.5 hdi, we have it in our 308sw, it is ok, could do with more power compared to what I am used to but its fuel economy is not good as I would expect. As an example, on long runs to the Lake District in our previous 1.6 hdi C4 we would get 65 to 70 mpg, the 308 gives around 55 mpg. We also have a 1.5 petrol Skoda Octavia estate and the fuel economy on that is as good as the 308 if not better, surprising for a petrol. The small engines and ones with low power in cars seem to be the result of EU rules to reduce emissions.

I've been checking again this evening looking at many car dealers, there are many DS7s but most are around that grey cam area agewise and mileage, I am starting to lose faith in psa/stellantis produced engines. I have (dare I say it here, a 2015 Ford C-max 1.6tdci Titanium X, and quite honestly is a super to live with car.) but for some reason drawn to the DS7. It was Peugeot 3008s at first but their reputation made me look to something else. I will take onboard your replies, see where I end up. Thanks.

Ford also used the 1.5 hdi that can have the cam shaft chain problem, it put us off a Focus estate that we quite liked before getting the Skoda.
