This problem is now resolved. Please see my post here summarising the solution.

Original post follows below:



Hi,

I've had my MK6 GTI for a few days and have noticed a slight rattle when I accelerate hard.

It sounds like the E46 M3 that rattling sound when accelerating hard.

Any idea or anyone have the same issue.....

Could it be that it's still new?

Hey, i got mine about two weeks back. I had the same issue and i though something was majorly wrong. All it is is the front tyres losing traction and the axle sorta bounces. I think that it tends to happen in FWD cars. I'm not 100% yet but im pretty sure thats what it is.
So no need to worry.

Thats usually pretty solid wheelspin and you need a TAI to fix it I believe.
I don't think many people here a familiar with E46 M3's also Not to the point of knowing the rattle they maake under hard acceleration.

What was the problem in the M3 that caused the rattle?
150k car has rattle, perhaps 50k car does too?

Depends if it sounds detrimental or just like interior rattles.

Plus the 2.0T sounds like a tractor anyway if the mk6 soudns like a mk5

I may have had a different issue then. I accelerated quite hard in the wet and it semed like the front of the car jolted and bounced. I was told by my good friend who has been a mechanic for over 30 years specailising in german vehichles tht it was what i explained above, so unless he's wrong (which i highly doubt because he is veryy knowledgable and trustworthy) u may have a different problem all together.

[Corey_R]

Yeah - you're talking about a totally different thing.

The original poster mentions a 'slight rattle' rather than a jolting bounce
Btw, which tyres do you have?

[GTI2708]

I have the stock Potenzas that come with the GTI Mk6.

Yeah you are getting axle tramp my friend. MkV's do it which is how I know what you mean. Tehre are Torque Arm Inserts and Anti-lift kits available to help keep those frontsp planted.
Well I know there are for mkv, shouldn't take too much/too long for the mk6 kits to be ready.

Yeah interesting point, what tyres have you got? I experienced the axle tramp with Conti CSC2's.

Still got the OP to sort out though...

[GTI2708]

I have Bridgestone Potenza 205/50 i think....they come with the car.
How much did those packs cost on the Mkv and how did u get them?

205/50 geezus!

Lol, it's my old mans car. His is 05 BMP with 30k kms on it. Doens't get driven enough to warrant it.


Ahhm, try www.rennenhaus.com, enquire there, Ian has contact with people in the states who I'm sure are developing parts for them.

Tim at Dubaddiction (froum sponsor)

ECS
TMTuning

There are a few.

Alternatively (I haven't been there, no need) see if there is a mk6 section on VwVortex

I'd try Ian as far as your TAI goes first though

Yeah - I had that issue with the Potenzas too. Changed to Federal SS595's (cause I couldn't afford Continental Sport Contact 2's at the time) and the issue went away. I've got the CSC2's on my Polo GTI now and don't have the issue either.

[QUOTE=schoona;437061]205/50 geezus!

Hahaha, is that good or bad geezus? I'm not very knowledgable when it comes to tyres.

[schoona]

Your wheel is 7.5" wide with a tyre tread pattern 8" wide. Then you have 50% of that in your sidewall.

205mm (width of tyre), 50 = 50 percent of width for your sidewall height.
That is a lot of tyre.

Im not sure how "stiff" potenzas are, I haven't driven on them, but oyu shouldn't be getting to many problem with power down because the contact patch will "bulge" onto the road and aid traction.

Your ride shjould also be very very bearable with those tyres.

[GTI2708]

Ah ok then...i'll try to learn what all that means....
It's usually very good with traction but when i really plant it from a stand still it seems to always lose whatever traction it has...or in the least chirp quite a lot.
I think the problem is my foot. ahha i'm sure i'll learn to take off a bit more controlled in good time. I'm going to put some 18" rims on it soonish, what tyres would you recomend to put on them?
something not too too expensive.
Thanks

It's a dreaded word up here "Tempe", but I have a mate with a mkv, got 19" RS4 reps with Kumho KU31's for 2k all up.
Sure you can smoke them, but with a bit of moderaion get pretty good traction. His car rides/looks/feels better on the 19s for sure.

I have Bridgestone Adrenalin RE001s on my VR6. Only time they have spun is having the engine loaded around a left hand turn and punching it in first. 200 a pop for 15s But they are awesome so...

Id have a look at Continental, good rubber, Pirelli (though I seem to recall wear rates not being so crash hot), Michelin Pilot Sports, even Federals/Falken could be a goer.

Falken 452's

[FredGTI]

I've got the standard Potenza's on it.
...
It's like a rattle from under the car when I accelerate hard and then back off...around 1800 - 2300rpm.....

My mate thinks his MK5 is the same under hard acceleration he thinks its because it has too change gears and drop from 5th...but i'm talking about taking off in 1st.....

I think i should call the VW dealer nad have them check it out....

apart from that...all smiles from me
