Lone_Bullet Posted October 24, 2016 Report Share Posted October 24, 2016 Like the computer thread, but it has to have wheels 'n' stuff. Got a '04 Audi A3 8P 1.9 TDI 105bhp version. Had to replace the clutchpump, a year later the clutch and flywheel. Bummer. Now it drives great but I noticed a 'dok dok' sound under these conditions : - Clutch connected ( pedal not pressed) - Speed greater than 60km/h or 40m/h - Accelerating ( either by throttle pedal or cruise control) So only when 3 of these conditions meet. Anyone has an idea? I was thinking something turning out of ballance. Like a bad ball bearing or so, but Inhear no screeching. Sent from my C6603 using Tapatalk Link to post Share on other sites
shmook Posted October 24, 2016 Report Share Posted October 24, 2016 Bearings tend not to screech, more 'rumble' with maybe some vibration, which gets progressively worse:) Link to post Share on other sites
Lone_Bullet Posted October 24, 2016 Author Report Share Posted October 24, 2016 Rumble, yeah... Problem is, I don't drive a lot so I can hardly tell if it's getting worse. Sent from my C6603 using Tapatalk Link to post Share on other sites
shmook Posted October 24, 2016 Report Share Posted October 24, 2016 They take ages to get worse, but I would get it looked at Link to post Share on other sites
amateurstuntman Posted October 24, 2016 Report Share Posted October 24, 2016 That sounds like a mis-calibrated turboencabulator. Link to post Share on other sites

Tinkerton Posted October 24, 2016 Report Share Posted October 24, 2016 is it just 'dok dok' or is it 'dok dok dok dok dok dok (ad naseum)'? does the speed of the doking change? if yes, does the interval between doks change as you change road speed? is it only in a straight line or only when going around corners or both?

amateurstuntman Posted October 24, 2016 Report Share Posted October 24, 2016 Tink is interested in your dok. Link to post Share on other sites
Lone_Bullet Posted October 25, 2016 Author Report Share Posted October 25, 2016 xD The interval speeds up as my car speeds up, yes . Weirdly enough, it doesn't 'dok' at speed when not accelerating. Dok dok dok dok dok dok et nauseum Sent from my C6603 using Tapatalk Link to post Share on other sites
Tinkerton Posted October 25, 2016 Report Share Posted October 25, 2016 So it doks faster as you go faster, but once you stop accelerating it stops dokking? Link to post Share on other sites
amateurstuntman Posted October 25, 2016 Report Share Posted October 25, 2016 That's bad, speed related noise but only under load. What about the cornering Tink asked about. Sounds like the diff to me. I had that after I got an LSD fitted, turns out Quaife dropped my crown wheel. Link to post Share on other sites
Tinkerton Posted October 25, 2016 Report Share Posted October 25, 2016 I was wondering a banjaxed DMF but he says he had that changed avec clutch last year. Diff might be possible but ive never heard of a diff going in a standard 1.9 PD, let alone the lower tuned ones. CV joint? Link to post Share on other sites
shmook Posted October 25, 2016 Report Share Posted October 25, 2016 Cv joint would be worse on cornering though, surely? Link to post Share on other sites
Tinkerton Posted October 25, 2016 Report Share Posted October 25, 2016 Yeah, and going over bumps etc but we don't know if it does get worse on cornering yet until Martin weighs in. Link to post Share on other sites
shmook Posted October 25, 2016 Report Share Posted October 25, 2016 Very true Link to post Share on other sites
Lone_Bullet Posted October 26, 2016 Author Report Share Posted October 26, 2016 I'll try in cornerin this afternoon, but I don't think so. It does indeed stop making the sound if I stop pressing the throttle. It's quite a soft sound, but noticeable. Sent from my C6603 using Tapatalk Link to post Share on other sites
Lone_Bullet Posted October 26, 2016 Author Report Share Posted October 26, 2016 Just checked, not in cornering but... 4th and 5th gear from 1900 to around 2400 rpm. Higher rpm anf it goes away. ( or might be drowned out by engine noise). Sent from my C6603 using Tapatalk Link to post Share on other sites
shmook Posted October 26, 2016 Report Share Posted October 26, 2016 Thrust bearing? Link to post Share on other sites
Tinkerton Posted October 26, 2016 Report Share Posted October 26, 2016 Wouldn't be only under acceleration. (Also fnar thrust) Link to post Share on other sites
shmook Posted October 26, 2016 Report Share Posted October 26, 2016 Fnar. True too. Link to post Share on other sites
hitmanNo2 Posted November 24, 2016 Report Share Posted November 24, 2016 What are everyone's thoughts on supermarket fuel? I'm talking petrol if that makes a difference. I've always used Shell or Esso but now I can get supermarket fuel for under a £1, I'm tempted. I gather it's all the same fuel, just with difference additives. Is there really much of a difference?
