2004 54 plate 1.9 CDTi
Is there an updated wiring/injector/common rail harness available?
I currently don`t have a problem,but I`ve read in some threads about updated wiring harnesses.It alludes to the the early engines have 1.5mm cables and the newer versions have 2.5mm cable.Some sypmtoms of harnesses being poor acceleration,hesitation and juddering at low speeds.
Would it be prudent to change to the new harness?
Worth the bother?
Easy to do on your own or does it need a garage to do it?
Thanks in advance
