tappy hdi - puggyhdi - 15-03-2012
hi guys new to this but wondering if you could help, simple question, my cars engine is sounding quite tappy until i get to 3k then sounds normal, it runs perfectly fine. not sure what it could be, thanks tom,
Re: tappy hdi - cully - 15-03-2012
probably the injectors if it goes quiet after 2.5-3krpm
id suggest turning the radio up!! as if its not broken dont throw money at injectors just to quieten them
its just a waste of good money

I think most of them do it iirc isn't it the turbo the kind of ticks? Mine does it and mines (touchwood) never let me down.
Re: tappy hdi - Poodle - 15-03-2012
Nope, definitely the injectors mate lol. If your turbo's ticking that's a whole other story!
Personally i'd say it depends how bad the ticking is, gained 3-4 mpg when i replaced my injectors with good refurbs. Mine were properly shagged though tbf lol.

Whats the best injector cleaner to use?
Re: tappy hdi - Bri-HDI - 16-03-2012
A certain amount of injector tick is normal, ive had it on mine for years and it goes away after a certain rpm, if it gets worse or louder get it looked at but for now i'd leave it.

Diesel. Not being funny, just not found an "injector cleaner" or "fuel system cleaner" yet that makes what i'd call a worthwhile difference. Was some dude on TDOC a while back claiming he'd found a good one, but then it turned out he was a distributor for the stuff, so possibly a bit biased/fos lmao.
Re: tappy hdi - Mr Whippy - 16-03-2012
The front of the Bosch manual for the injection system on the 306 HDi says in big red letters, DO NOT USE FUEL CLEANERS/ADDITIVES ON THIS SYSTEM... or words very similar to that effect.
There are baskets on top of the injectors that act as filters, there are filters in the tank pump, and a pre-high pressure filter on the engine too. Cleaning out all those is something the fuel cleaner won't do... if anything it'll just dislodge more crap to block up the injector basket filters!?
I'd save up and get new filters and maybe an ultrasonic clean on the injectors done, it'll make more long term difference than cleaners which Bosch say you shouldn't use!
Tappy injectors seems to be a characteristic, and fuel cleaner won't fix it. Even the very best HDi's I've seen have ticked loudly, while some cars that look like they are on deaths door, had very subtle ticking noises.

I used to notice the 'ticking' quite a lot when i first got the car and shortly after went stage 1 but then it just seemed to disappear one day
Re: tappy hdi - Mr Whippy - 16-03-2012
My brothers car did that too, remap on, went away, remap off, came back haha!
Ah those were the days... I still had my GTi6 and we were just putting random maps on his car to see if they worked (off the DVD you got)
I think we ran a 362 map on his 162. Light was on but it ran really really well. Probably 'too' well hehe... was a dicky map looking back, loads of power, but all the wrong ways of going about it.

Re: tappy hdi - Connor - 16-03-2012
Apparently its to do with pre injection and keeping emissions down, because after 3k it doesn't bother with the pre ignition, i think i read that was what caused it
Re: tappy hdi - puggyhdi - 17-03-2012
was thinking of just taking hdi injectors from the scrap yard and trying them but if that dont work ill just put the old 1s back in, least i never payed for them. so no loss
Re: tappy hdi - 4WayDiablo - 17-03-2012
Heard this yesterday and it really does make a racket!
Doesnt sound healthy.. i should have got a vid
Re: tappy hdi - lh_4827 - 17-03-2012
mines really loud when i can hear a reflection of the sound off a wall.. cant hear it otherwise.. but i have a solution..
...keep it above 3k
Re: tappy hdi - 4WayDiablo - 17-03-2012
This was enough to hear loudly outside the car too
Re: tappy hdi - Poodle - 17-03-2012
Hmmm, that doesn't sound promising, where are you based exactly?
Re: tappy hdi - puggyhdi - 17-03-2012
waterlooville area mate, and the car sounds fine now when driving, even before 3k as i has now fitted injectors from an xsara hdi thanks to the scrappy lol, so all good
Re: tappy hdi - Poodle - 18-03-2012
