PSA Group 1.6 'HDi' engine / Renault-Nis 1.5d Dci

goatfertility

Similar engines in terms of litre-age, but I have heard absolutely terrible things about the 1.6 HDi. Are vans with that engine (Like the Dispatch / Expert / Scudo etc) really worth avoiding like the plague?

Whereas as the Renault group K9K 1.5 Dci series engines seem much more reliable. But how do they hold up after say 150-200k?

Struggling to find high mileage examples of either in a van.

Yes. The 1.6HDI is a pig of a thing. Probably "ok" if its well maintained from new - i had one through my books when i was trading with 160K miles and driving beautifully - fully documented main franchise service history though (and some big bills along the way).

The 1.5DCI isnt perfect either - the newer the better though.

As said they're OK if serviced regularly. Halve the oil change mileage though. Apparently (I read somewhere) the taxi guys love them, but they're religious about the servicing.
There's a proper oil change procedure for the engine(s) as well (Citroen service update I think). Has to be done with engine at working temperature, and oil drained through sump plug, and left to drain properly.

The problem is - as a used car buyer its not just enough that you service it regularly going forward - its as much about how attentive the previous owner was.

True with any engine of course, but more so with these. Problem is you're not going to be able to look at any oil strainers etc when buying one. Probably best left alone unless you really know what has happened to one.

How reliable they are is down to service history.
The big problem is if they've not been serviced on time, and with the correct oil, the oil galleries get clogged, and block the feed to the turbo.


If you come across one that has had a new turbo fitted recently, walk away. Even following the correct replacement procedure, which involves replacing the oil pump pickup, doing oil flushes, and checking the return flow from the turbo, will not guarantee the same thing won't happen again.
However, if you do buy one, change the oil as soon as you get it, and do a change inbetween the official oil change interval.
