V6 4Motion CC has poor throttle response - any known solutions??

[Elmura]

I've got both a VW R36 and a MY12 CC V6. I'm selling the R36 but this car is my reference for handling, exhaust noise, and performance (as far as large family luxury sports cars go).

The MY12 CC (fitted with some options & mods) is better in nearly every way except:

1. Seats don't have inflatable side bolsters so, my small frame slides around when cornering moderately hard
2. Exhaust is silent - surprisingly it doesn't make it slower than R36 (I measured), but it feels slower
3. Handling, with Sport Mode and Eibach Sports springs (~20mm lower), is not sharp and the body rolls too much
4. Part Throttle response is very poor

Now, I realise the CC is more the luxury cruiser vs the R36 is designed to be a sports car, but I want the best of both worlds...

I'm figuring the electronic throttle is tuned for economy because the car shifts up gears rapidly in D and, even with moderate throttle openings, the car goes NOWHERE. It's actually dangerous. Entering traffic from a side street, or turning in front of traffic are frightening. You either have no power, or you put your foot down and get too much power... Part throttle acceleration is sluggish!

I have to fix this, whether it's DIY (preferable) or through a tune. Please point me in the direction of a fix if you know. At this stage, I'm thinking of intercepting the throttle wire but this is a bit of a hack.

Sprint Booster?

I think R36 beats CC in every way though

Are you using the DSG in drive mode or sport mode? I found my MY12 V6 4motion CC is smooth and sedate in Drive mode but a different animal in Sport mode. Throttle response seems improved, holds gears longer and blips the throttle on down shifts. I've never driven an R36 to compare though.

Maybe a standard model, but not the MY12 V6 4Motion CC I purchased with the upgrades fitted (R pedals, R scuff plates, R steering wheel, Eibach Pro springs, gorgeous Nappa stitched leather, LED DRLs, full phonebook Bluetooth function, hard drive and on and on. I'll put up a full comparison at some point

Definite difference with CC in Sport mode, but in the R36, it's pretty wild (sound, response, urgency) but is too much for regular driving for fuel, noise and eagerness. I prefer Manual mode for sporty driving, or Drive for regular. It's the regular side that is very subdued feeling. I find I have to press throttle more and more as gears rise through 4th or down shift it. Something I don't do in the R36. It seems a different tune to either throttle, gear shift timing or fuel efficiency.
At full throttle, it's actually a smidgen faster than the R36 (I measured with GPS based app). Could be wear on the R36 (76000km vs 27000k on CC)

Reset the DSG, and drive it in a manner that suits you, and it'll adapt to suit.

There's plenty on Google on how to reset it.

Will do, thanks for the tip

Well, I just found out that the previous owner had fitted (and removed before advertising for sale) a SprintBooster and set it to Green (moderate boost). So the ECU figured that the only way the throttle is going to respond is with large pedal travel....

Seems I have to somehow, re-educate it. I did a quick search for throttle reset. Seems you need a VCDS / VAG-COM. Some are saying they got some success with a so-called "chicken dance" but this was on much older cars, so not sure.

Any experience with this.

PS - I did a DSG reset and it slightly improved things like moderately accelerating from rest where before I'd get a big hesitation then a jolt with a drop in revs.

[Umai Naa!!]

Keep driving it, and the DSG should adapt to how you drive.

ah, ok, saw that CC on carsales, Congrates on the purchase!
but you can not compare standard R36 with modified CC...
btw, the LED DRLs does not cost $1000 as the previous owner claimed

I got a Harding Performance DSG tune on my 6 speed wet clutch via one of their distributors (Volkspower) in Melbourne and couldn't be happier. It's expensive but it transforms the car. It really does what’s claimed. It makes the care more driveable. It holds gears for longer in D and holds gears for less time in S. It makes both D and S more useable.

Previously when turning a corner around the city, the car would enter the corner in say 5^th gear and stay in that gear on exit with no useable power. Several subtle throttle applications on exit would produce no results until the DSG suddenly jolted into 1^st gear with lots of revs. With this upgrade the car changes down gears when entering a corner in much the same way you would yourself if you were driving a manual. When exiting the corner, the car is already in 2^nd gear ready for effective acceleration. The upgrade prevents the DSG from dropping into 6th until 70 km/h. If you want more sporty changes, then S works well without being so manic as before.

Interesting review 3C4M. Thanks. For me, I'm happy to control the box manually or override it in auto when entering or exiting roundabouts / corners. Though the lifting of the torque limit and the faster shifts has me interested for allowing modified grunt.

I don't recall him stating the DRLs are $1k, they're around $200 + install. Why can't I compare the R36 with a BWS 4Motion CC ??? I have both and each has its merits. It's not an apples and oranges comparison. They have the same engine, driveline, brake rotors, wheel size, tyre size, similar weight, wheel base, track. They share heaps. For me, the CC softer tuned suspension & quiet exhaust need modding to suit my preferences of sports driving. The Eibach springs help a little (they're very comfy for lowered springs) and forthcoming Whiteline sway bars will round it out. An exhaust mod is on the cards as well (I'll update when that's done).

I purchased a VAG-COM cable and VCDS software (full Hex Can function) to tweak my car and customers cars in the South West of Sydney. My initial complaints of poor throttle response and hesitant acceleration from stand-still have been mostly resolved. Compared to the soft DSG reset suggested by Umai Naa!! , VCDS adaptation did a much better job with DSG and throttle.
If I didn't have the R36, I would probably think it's a design flaw.

Still, the R36 has still greater part throttle street driving responsiveness which I've come to figure out as being due to the shorter gearing. In the R36 at 100kph, the RPMs are around 2400rpm by memory; the CC at same speed is around 2000rpm. The BWS V6 3.6L engine produces max torque from 2400rpm and up so it's real responsive at that RPM. To get the same responsiveness in the CC, you need to drop a gear.

How did you tune the DSG with the VAGCOM? Is it complicated? I am not particularly happy with the quirky DSG at low speed and changing between D and R, can this be improved with the cable?

Oh I got a CC V6 too

Thanks.

[Elmura]

There's a procedure to it. If you're in Sydney, PM me to get it done along with throttle reset & optionally, intake mods.
Else, contact a local VW specialist. Big improvement; and it improves further over the next few weeks.
