NOISY TD5

<< < (2/3) > >>

Hightower:
I don't know how true this is, but I have been told that TD5's essentially start on only 4 cylinders which is why they can be a bit noisy.
Mine certainly rattles first thing and then gets better when warmed up.

thermidorthelobster:
Only 4 cylinders have glow plugs.  I have no idea why.  So, I guess the 5th isn't really doing much until it warms up a bit.  But surely this would happen pretty quickly, after only a few seconds at most.

I found my TD5 rattled less and ran generally more smoothly after I got it chipped.  Good excuse to get it chipped then!

LOFTY:
Mine rattles as well, goes after about 500 yards up road.
Worst problem is throttle, get to about third throttle, then a slight touch, and it takes of like a scalded cat, had it checked with TestBook, all ok.
Anyone changed throttle potentiometer before? :?

Wanderer:
Not a bad guess at a glow plug then.
It's not even there. Tight beggars.  :lol:

Range Rover Blues:
Had the same thing on my old Cav when the pre-heaters packed up, cranking revs and too much unburned fuel!
It's worth checking to see if your injectors need overhauling anyway, a lot of makes do and it can help with fuel economy and reducing smoke emnissions.  Direct injections engines are noisy though, especialy when cold because the pistons don't fit (pistons are usually oval when cold).  Add this to the lack of a combustion source (no glow plug) and the Dieseling sound you hear is explainable.
