1st gear noise

[modfan61]

Hey all, have had this noise for awhile and couldn't pin-point it. When I'm going from a stop in 1st I have a noise. Almost like a rattle. At first I thought it was power steering. It sounded just like it, but with some rattling. My power steering was making noise but that's been fixed and the noise is still there. It only happens in 1st, and seems to be louder under load (when I'm giving it some throttle). When I shift up to 2nd it goes away. There's no vibration, and I don't feel it through the shifter. It sounds almost like the cam chain would be loose but I would think that would cause the noise in every gear... any thoughts? I'm not TOO concerned by it, because I'm not in 1st very often, but it's just a bit annoying..

I also had a noise under full throttle, it sounded like a grinding noise, and it ended up to be a broken exhaust mount, which made the exhaust pipe touch the body of the car. I can't exactly imagine the noise you are describing, does it also do it when selecting the first gear, or only when running in the first gear? It might be the clutch going out, or it might be a bad gearbox mount. It's surprising how much the gearbox can move under high torque when the mount is bad.

[modfan61]

It does it no matter how much throttle is applied. Even under very light throttle but still under load. I don't think it's the exhaust. That was replaced before the car was bought and there's no real clunks. Only happens when running first gear. Fortunately, isn't a long time until I shift up.

Thinking of checking the fluid in the trans and putting in Redline MT-90. I haven't used that stuff myself, but it's what I've read is the best to use in these. I'm not sure what was put in before the car was bought

[Laurentiu]

Is it a manual or auto?

[modfan61]

Manual. 6spd

I have the same noise in 1st only. Like a ticking noise that increases with speed. Not present in any other gear but 1st.

YES. Ticking is probably a better word to use than rattling. Also has some "whining" as well that sounds like a dry power steering pump almost. Then once I go to second and it's GONE

First gear set are scored, or teeth are chipped.

My car is the same, on a 2003 model with an 02X 6-speed manual. It hasn’t gotten any worse, and I’m not too bothered, as I’ll be fitting a built 01E as part of my build.

that's what I've read. That it's a chipped tooth possibly or scored or whatever. Seems fairly common.. how long has yours been noisy?

No change since September 2016.

[Laurentiu]

That's interesting, I have 2 B6s, one is a diesel, 190k miles, and the other is a 1.8t, 87000 miles, no problem with the gearbox on any of them...

[modfan61]

Well that's a little re-assuring. As mentioned, it's not like I beat on 1st gear and I'm not in it very long so I'm not too worried about it where I think it'll blow the trans. It's just a little annoying with the windows down. When they're up it's not too bad

[walky_talky20]

This was also a failure in the 5-speed 01A transmissions in the B5's. Usually the V6 cars (probably due to more torque). It wasn't hugely common, but it did happen. I never heard of it progressing into a full failure or anything. Just noise during first gear, some worse than others.

An upgrade to a magnetic drain plug probably wouldn't be the worst idea - to catch the bits.

I'm going to order the service kit. Found it on UROTuning https://www.urotuning.com/Manual-Tra...-audi-6spd.htm. I'm not sure if ECS carries the 'kit' including the drain plug or a magnetic drain plug. My work has ECS blocked for some reason

[ralleyquattro]

In my case the the 3.0 makes the noise while the 1.8T does not.

From what I read, in the US the 3.0 didn't get the 02X until 2004. Did non North America countres get it earlier or was it swapped in?

Mine was swapped in, but the donor car was also a 2003 3.0 Quattro.

2003 was the change-over year for the 01E to 02X 6-speed manual in Europe and Australia. I’m not sure about North America and Canada, but I doubt they would be any different. North American cars were still built in Ingolstadt, Germany.

Interesting, everything I have read on the vehicles imported into north america shows them as having the 01E for 2003. Looking at the option sheet on a 2003 I found on CAR-Part.com shows GBE, used unit on Ebay from a 2003 sure looks like an 01E.

If you were to put it on neutral, could you recreate the noise through whichever rpm is comes about?

Correct.Which is why I said 2003 was the change-over year.

To be clear... 2003 model year got the 01E. 2004 model year was the change over and got the 02X.

[5ktq]

In the US/can, but it could have been mid year in Europe (maybe they made our cars first). If you look in ETKA it should show the VIN break

[Kevin C]

Does it break by model year?

THIS. I've had a grinding noise that occurs around 2k-3k, not all the time because if I give it gas and quickly rise past where it happens in the rpm it won't make a sound. I've had this noise since September 2015 and it does in fact happen even when in neutral at a stop.

[Jakal]

Mannn I mention something and everyone goes silent it seems.

OP, it sounds like you are describing a chipped tooth in first gear. My 02X has sounded like that for nearly 10 years. 1 year and a bit of that has been bolted to a 2.7t with 500+ ftlbs (at the f/w) so I wouldn't worry about it. It just sounds like crap.

Mine isn't like that. Tried it over the weekend. Maybe yours is exhaust rattle?..

That's what it seems to be narrowed down to. Good to hear some assurance that I shouldn't worry about it. True though, it does just sound like crap

The notion before was that it’s a heat shield rattling but I have no idea. The whole exhaust has been changed besides the cat and it still happens.

[APC123]

Hmmm, well jakal it seems that yours isn’t gearing based. But OP, it seems that yours goes on when things are spinning. So it doesn’t make noise in neutral, only in gear. Go through the same RPM’s in each gear whilst driving and see if the noise begins then. If you are at 3.5k in 5th gear with no noise, but 3.5k in 1st with noise, then you are on to something. Try it with all the gears. Narrow it down as best you can in this fashion.
