MAN fault codes

annitram:
Hi All

My TGA (D28 engine 480BHP) had these fault codes so was put into Feathers at Halifax all injectors repaired also the pump. But there is also a wiring loom in with the injectors and these are prone to failing.
If by any chance your truck is under warranty or an R&M contract then get them to repair it immediately as the repair cost was £2,500 + VAT. On the plus side my truck performs a lot better than it did. :sunglasses:

D28 common rails are quite rare, anything 2005 onwards will almost certainly be D20/D26 lump.

As a general rule the injector loom is only replaced if:

a: it is leaking around where the loom goes into the head

Or

b: the idle speed fluctuates on it’s own accord (this is down to oil leaking inside the loom and interfering with the electronic signals to the injectors)

Like you say, MAN R+M is a good idea when you consider the complexity of modern engines. You only need a couple of expensive parts to fail and the R+M has paid for itself.
