There are a few well known and well documented faults with the HDI engine, but if looked after, can prove to also be a very reliable workhorse.
Just seen this little ditty on the header for the engine section, what well known faults would these be please?

You're probably the first to read that lol.
I would say crank pulley, lift pump and fuel pressure reg are the most common faults.

Exactly as above tbh, the rest either aren't particular to HDi engines or couldn't really be called common problems.
