hdi ticking! - Steve_g - 19-09-2012
hi guys, my hdi is making a ticking noise when accelerating between 2000-3000rpm, when i ease off the throttle the noise stops and also the noise does not occur when stationary when i rev the engine, boost leak ??
i got the mrs to record the noise,:
any suggestions ?
cheers guys

Not watched the video but if it stops at 3200 it's your injectors just being noisy.
RE: hdi ticking! - Jonny81191 - 20-09-2012
yeah, injectors.. nothing to worry about from what I understand!
RE: hdi ticking! - 1616six - 20-09-2012
Mine are the same, i can boot it & it'll just stop ticking at 3.2k revs, nothing major, just an annoyance
RE: hdi ticking! - Steve_g - 20-09-2012
Ok cheers guys, its just it seems like the car is dwn on power, it struggles to rev past 3k
RE: hdi ticking! - Toms306 - 20-09-2012
Injectors would have to be pretty bad to stop it revving past 3k. Possibly 2 unrelated issues there, if the MAF sensor is failing it will struggle to rev past 3k.....unplug it and see if theres a difference.
RE: hdi ticking! - Steve_g - 20-09-2012
Ok where is the MAF sensor ? and by doing this will i harm the engine at all ? Cheers
RE: hdi ticking! - Toms306 - 20-09-2012
Nope, won't harm it at all. The sensor is located in the air piping just after the airbox iirc.

Ok thanks mate

Don't unplug it while its running. How many miles has the car done?
That sounds pretty bad, could be the crank pulley. Was that full throttle? Can see its got 130k on the clock in the vid actually, injectors may need a refurb, but that's not cheap so check your other options first. Does it smoke at all?
RE: hdi ticking! - Steve_g - 20-09-2012
Not much smoke until 3000-35000rpm when there is a bit of smoke, i cant remember if it was full throttle but the car is not quick really, 2 injectors were done by the previous owner a just over a year ago so could be.
RE: hdi ticking! - Poodle - 20-09-2012
I'm pretty sure mine started smoking about 3-3.5k, back when i had shagged injectors... Maybe worth a look then, try doing a leak-off test on them and see what that tells you (Cully has a thread in the guide section on how to do this).
