jimmyp Posted October 17, 2005 Report Share Posted October 17, 2005 Having had a phone call from the dealer this afternoon, I have been told that the metallic rattle between 1400 and 1600rpm is actually a characteristic of the car(!) and this noise is perfectly normal(!). However, I have been told by an independent specialist that it is not normal and needs to be looked at. Guys, will you please take your R's for a short 5 or 10 minute drive, pull up somewhere quiet, wind down your window, hold the revs at 1600rpm and see if you get a (characteristic) metallic rattling noise!?! Please can you all report back if you do or don't, as I have a sneaky suspision that it's not normal and Breeze VW are once again talking out their exhaust.

boxerdogted Posted October 17, 2005 Report Share Posted October 17, 2005 I have just had a new engine fitted for this fault under warranty,dont give in keep onto them. My new engine is a lot quieter,mine was changed at 12500 miles (Fault reported at 9500). Ring VW customer service and get them to create a case number.

Zenyck100 Posted October 17, 2005 Report Share Posted October 17, 2005 just tested mine. i think i know the noise you are refering to. i can hear it on my R more when driving it, noticed it a while back. its very quiet but it doesnt sound very metalic to me. i find it hard to hear if a just rev her to 1600 rpm parked up, but i do get a noise very slight though when you get the revs in the right spot. its always been there on my R, had it since march this year and hasnt got louder. not the answer you wanted to hear but i do hear summit.

dazr32 Posted October 17, 2005 Report Share Posted October 17, 2005 just been out in mine , what a bugger trying to hold the revs at 1600 i heard something but i wouldnt say it was a definate rattle more like a clicking but defo from the front end and not the back.

dave_uk Posted October 17, 2005 Report Share Posted October 17, 2005 Mine ratles like that, especially when cold - thought it was just when the exhaust was cold - any other thoughts. Link to comment Share on other sites More sharing options...
boxerdogted Posted October 17, 2005 Report Share Posted October 17, 2005 Mine was dead quite when cold, the noise only appeared when realy hot between 1400 and 1600rpm. There are known faults which VW wont admit to (Timing chain,crankshaft endfloat,oil pump drive etc). Check VW Vortex forum. It is strange that VW had a new engine in stock.

dazr32 Posted October 17, 2005 Report Share Posted October 17, 2005 i thought these 3.2 engines were bullet proof, i cant believe that vw can get an engine so wrong, obviously people have got issues which have highlighted underlying faults that could catch a lot of people out if they are unfortunate enough to have there engines fail out of warranty.

Mook Posted October 18, 2005 Report Share Posted October 18, 2005 It will either be the catalytic converter shield rattling or some of the cells in the cat, if you're still running your stock one. There was a thread on this a while ago Jimmy, but I can't find it. Warranty job Link to comment Share on other sites More sharing options...
jimmyp Posted October 18, 2005 Author Report Share Posted October 18, 2005 It isn't the cat as it was doing it before I had the new high flow cat fitted. And referring back to boxerdogted mine only does it when its warm, there's no sign when its cold. I'm gonna keep chasing this issue until it is once and for all sorted.

leno Posted October 18, 2005 Report Share Posted October 18, 2005 I've got a rattle, it's from the cup holder cover! Link to comment Share on other sites More sharing options...
dazr32 Posted October 18, 2005 Report Share Posted October 18, 2005 do people think there is a genuine major fault with these engines or do you think that a couple of our fellow tsn'ers have been unlucky. Link to comment Share on other sites More sharing options...

[/ QUOTE ] The baffles in the Milltek rear silencer do rattle Jimmy, more so when you use a heavy right foot. There's nothing wrong with it - it's just a characterisic of the Milltek, so this could be the cause of the rattle? Have you figured out where the noise is coming from - front, middle or rear of the car? Link to comment Share on other sites More sharing options...
boxerdogted Posted October 19, 2005 Report Share Posted October 19, 2005 The noise on mine was 100% engine noise,not cat or milltek exhaust. The noise comes from the drivers side of the engine,i had numerous things changed prior to the engine being replaced. I have thirty years experience in the motor trade and made VW and the dealer aware of this so they could not pull the wool over my eyes. As i said before keep on to them until they fix it.

BigMeanBob Posted October 19, 2005 Report Share Posted October 19, 2005 I find the noise from the Miltek back box a bit embarassing when the car is cold actually....the popping noise drives me crazy. Seems to dissapear as the zorst warms up, but until then, the car seems to sound like a 1972 Nova when you let off the gas at higher revs... b0b Link to comment Share on other sites More sharing options...
calumcousins Posted October 19, 2005 Report Share Posted October 19, 2005 im pretty sure mine makes this noise too, only its more like from 1,800-2,000 rpm on mine. Coming from the drivers side of the engine bay, a sort of clicking rattly noise when the revs are held. You can hear it too when you drive along at that rpm. Its made the noise on mine for a while now (36,000mls) and id always assumed that it was a loose heat sheild or something similar (or just another VW "characteristic"), but all the talk of replacement engines is starting to make me worry now, especially seeing as i only have 3 months warranty left...

Mook Posted October 19, 2005 Report Share Posted October 19, 2005 That's the bit I like, Bob - accelerate up through the gears when it's cold - only up to 3K max though - and slow for a junction to hear pop, blurt, pop, schloop... Lovely Link to comment Share on other sites More sharing options...
ritchipa Posted October 19, 2005 Report Share Posted October 19, 2005 Hello all - Jimmy P I had all the same circumstances as you. Only when warm, no-load idle at circa 1500 - 1700 rpm. Having read the vortex article it makes sense to me that its the cam chain flicking around on a worn intermediate gear. Link to comment Share on other sites More sharing options...
Roland Posted October 19, 2005 Report Share Posted October 19, 2005 Well, this has had me worried for a while, I've been listening for the noise for a couple of days or so thinking I can hear it and you certainly can hear mine at tick over a sort of bouncing metallic sound when you increase the speed it goes away but comes back around the 1600 - 2000 rpm. It's not easy holding the throttle and listen at the same time, so although my partner thinks I'm mad even more so now, she helped me hold the revs while I listened with the bonnet open, and I found my noise - it's the aircon. If you place it in ECON no noise switch to AUTO and it immediately comes back. So I'm off to the dealer tomorrow to see what he thinks. Hope this may be of some help. I will admit when you stick your head down the side of the engine (drivers side) It sounds just like a slapping chain worried the crap out of me.

boxerdogted Posted October 19, 2005 Report Share Posted October 19, 2005 They thought that it might be the aircon compressor on mine so they ran it without the belt on and the noise was still there,this also iliminated the water pump,power steering pump and alternator.They had allready changed the water pump once and the belt and tensioner twice proir to doing this.I had allready iliminated external rattles from heatshields brackets etc. Link to comment Share on other sites More sharing options...
Dan32 Posted October 19, 2005 Report Share Posted October 19, 2005 Mine has always sounded a little bit rattley at those revs. Its probably just the camchain (?) as opposed to cambelt. Going to get told its a cambelt now!! As for cold morning pops and farts from the Milltek, moments i live for!! Especially with the CCAI, its made it even more pronounced. Understand you can get flames out of it, eh Charles Link to comment Share on other sites More sharing options...
Mook Posted October 20, 2005 Report Share Posted October 20, 2005 Not yet been out in the dark (to check for flames) since the CCAI was fitted when the engine's been cold, Dan, but I'm sure it would if you cranked it up to 6K rpm and lifted off Or have you managed to get flames to come out of the air filter at the front... I've got an aversion to taking the engine over 3K rpm until it's up to 90C though. The cam chain can rattle, but only when the links are seriously worn (i.e. very hard life at over 100K miles). The rattling comes from a small "wheel" (known as a cam chain tensioner gear) that the cam chain follows around - this is designed to keep it to the correct tension. A very small amount of rattling is normal at low revs. The problem that VAG discovered is that the teeth on some of the cam tensioner gears used in some of the 3.2 VR6 engines are wearing too fast, as the material that the teeth are made from is too soft. Hopefully this pic will make some sense of the inner workings of your engine (it's knocked together very quickly, so no measurements are accurate!): Other VW's (like the 1.9 TDI and 2.0 petrol) use a toothed rubber/polypropylene belt, to drive the cams, but these are prone to stripping when you crank too much power through them, hence VW going down the cam chain route when the originally built the 2.8 VR6 - the 3.2 being an oversized version of the same engine. Or is this all too technical for this time of the morning... Link to comment Share on other sites More sharing options...
jimmyp Posted October 21, 2005 Author Report Share Posted October 21, 2005 Ok the so called characteristic noise which i was told that is normal on the R's is actually the master tech's prognosis and not VW technical as i thought. The dealer will no longer work on my car now as they think its all perfectly normal (mainly as they are going to lose sooo much money)as they didn't find the fault the first time round,so i was advised by the workshop controller to go to a different VW dealer to get their opinion on this issue when i am 99.99% certain it is either the cam chain or tensioner,i am positive that Mook is right about the tensioner and this is the problem. So all i need now is to find time to get her in again Oh and the noise is defo coming from the engine, and no i'm not imagining it Link to comment Share on other sites More sharing options...
