Although HDI engines are recognized as very reliable, the 1.6 HDI is not as reliable.
Owners of the 1.6 HDI may need to replace the engine or recondition it for a number of reasons. These engines already have a reputation when it comes to frequent repairs, to operate all the time in optimal conditions.
Where does HDI come from?
HDI means “high-pressure direct injection”, this is the term used by the Peugeot Citroen group to define a turbo-diesel technology with a common-rail injection system.
At HDI, diesel is injected under pressure directly into the combustion chamber.
The first Peugeot model to incorporate HDI technology was the 406, followed by the 407, 307. The Citroen Berlingo also uses the same technology, but Ford’s competitors have borrowed the technology for some diesel engines.
Maintenance of HDI engines
Generally speaking, diesel engines should be serviced twice as often as gasoline engines.
The HDI turbo engine needs some attention and has the following problems: the turbine accumulates particles that clog it and affect the functionality of the engine. The solution is to change the turbine.
Other common problems with HDI occur with injectors that need to be changed quite often.
If you have not driven an HDI engine before, you should know that the engine does not feel like a new diesel engine at all. It makes all kinds of sounds, sometimes beats, is very noisy and can stop for no reason.
It is a rudimentary engine and this has advantages. It is cheap to repair and maintain, but you should know that repairs will be much more frequent compared to a newer diesel, but maintenance prices will also be much lower.
When it comes to common maintenance at 1.6 HDI, owners are forced to always add additives to the particulate filter or replace or clean the EGR. In addition, the engine does not require major maintenance.
A big plus for HDI is that the engine manufactured before 2010 can be replaced with one manufactured after 2010. The engines have an alphanumeric code and you can find the same engine, but from another year and automatically more efficient.
The pre-2010 engines did not have a turbine, most of them after 2010 have a turbine, are more efficient and quieter and come with a newer and more efficient injection system.
