Thread: CRD Injectors - Has anyone had any Problems with them?

I have not had issues with the injectors.
There is no specific replacement period on the TD5.
Yes water contamination can cause issues.
The TD5 has a water sensor on the filter and a drain point for when this happens.
Pumps can fail but will normally give plenty of warning first.
Defenders are expected to get poor fuel compared to the Disco or Rangie, don't know if this means they cope better or not.

TD5 is not common rail, have a read of Chop's issue with bad fuel in his Puma.

TD5 does not have CRD injectors.
They are unitary injectors which are energised by the camshaft and produce their own pressure ( except for the 35psi or so controlled by the Fuel Pressure Regulator). There is a spill valve controlled by the ECU which determines the fuel usage.

I would think that the TD5 injectors would be less likely to have water through them as the fuel filter has a water trap and alarm, much like the "water watch" alarm that people add to Jap 4x4s. In addition the fuel is heated and recirculated so the injector is not the final end point for the fuel .
I note the ECU can trim injector's duration while operating , so I assume the Crank position sensor measures engine acceleration by cylinder. The ECU advises trim by cylinder to readers such as Nanocom, so a fault is reported if one arises.( or the engine stops from a flat battery and you get all sorts of injector failure messages)

Questions on this forum suggest that they give little trouble except for the sealing washers and orings, although I note someone posted about a failure last week.
From everything I have read they do not fail at 100-130KK like the Toyota injectors.

Had two vehicles with CRD,both used all over the outback,not a single issue.Toyota's problems stem from injectors being out of spec from new and very cheap electric plugs.They also for some reason have problems with the ECU not accepting the injector codes,thats been a problem for 10 years or more.Denso don't have the quality control of Bosch IMHO.

I have a neighbor that recently purchased a 2010 Playdough. Not long after the injectors failed. Hugh $s to fix but lucky for him it was under used car warranty.

A bit later on they failed again and water in fuel was blamed. It needed injectors and pump. He claimed it on his insurance and they excepted it.

In hindsight he said if he had his time again he would get a different vehicle.

He went for the Tojo based on their so called good reputation.

As for the TD5, from all my research and owning one now with 190,000 on it,
I reckon the Td5 system is the best of both worlds. Has the benefits of common rail without the expense.

I believe that TD5 injectors are more forgiving that common rail and are streets ahead with pricing if needed.

Ask Dullbird also about her experience.

I think water is blamed for every single fuel issue,it seems to me to be the standard excuse for the masses. Pat

Just finished reading his post..... It seems the problem is still a little unknown and still not 100% sorted. It doesn't seem like its a common problem but for me a good reason to install a Aux Fuel filter.
