Hi Guys..Just wondering if anyone has experienced this. Come up to a speed hump( in Drive) doing about 10 kph,then ,once over,accelerate and car seems to jolt or bunny hop.Car has build date of Jan 2010. I tried this in S mode and same happens. Could it be a transmission problem,mechatronics issue or does the gearing need to be remapped?
Also when stopped at lights acceleration causes wheelspin.Should this not be controlled by traction control,hence allowing a controlled takeoff,rather than wheelspin? I cant believe that a new car would have this problem. Please Help.

Ref the bunnyhop: as the DSG doesn't utilise a torque converter like a conventional automatic, the car is somewhat more susceptible to bunnyhop if you're not very gentle and smooth on the throttle in first gear under certain circumstances. Could it be that you're being a little rough with it?Originally Posted by nardini
If not, I'd try following the DSG reset procedure (do a search on the forums for the steps - I recall it involves flooring the accelerator (with the engine/ignition OFF) for 20 seconds or so) to see if that fixes the problem.
And if that fails, it might be worth a call to your dealer / service manager.

Is it really 'bunnyhop' (as often suffered by learners on manual transmission) or axle tramp from an over-enthusiastic right foot?
Axle tramp is very easy to provoke on my TDI103 with DSG — equally easy to avoid.
Also, for wheelspin to be detected, it must first exist. Think on it...

I have a very slight 'bunnyhop' in my GTI too, but I believe it's normal as it is the gear engaging from neutral when you press on the accelerator after letting it roll for a bit at low speeds.

Probably a user problem, have you tried different ways to go over the speed hump like speed, angle and so on? Does it only do it on one speed hump or type of speed hump? Is it only when the car is cold? Without these details there isn't anything to go on.
0% wheel slip means bogged down car. 8-12% is the optimum amount of wheelspin for fast takeoff on a 2WD car. Why you think that just because the car is new it can put down 155kw of power through the front wheels without any wheel spin is beyond me.Also when stopped at lights acceleration causes wheelspin.Should this not be controlled by traction control,hence allowing a controlled takeoff,rather than wheelspin? I cant believe that a new car would have this problem. Please Help.

How do I quantify the % of wheelspin to achieve this optimal 8-12%, Maverick?

I have 5 x sets of speed humps (GRR) on the street directly off my works driveway, and I have never had what you
describe happen to me. My car in Jan 010 build too.
I will say though that I just slowly coast over the humps and dont plant my foot or anything once clear.
My "DSG" hasnt behaved any differently over these than my previous "auto" did?
Now you have had some feedback on different accelerator techniques, has this helped solve the issue?

To clear situation up-Took car to dealership,where chief mechanic test drove the car with me.There definitely was a problem-coil pack had to be replaced as spark wasn't being produced on cylinder 1.Didn't cost anything and now accelerates smoothly.

Other threads in the search results are older and in the MkV forum, so I'll bump this one:
Took the car to Pedders today for their $14 28-point check which you see advertised numerous times when the V8 Supercars are on, but more or less for the purpose of getting their opinion on what could be done regarding axle tramp on medium acceleration. Their comments on the report:
That was written before I told them about the ECU upgrade (the guy was quite impressed with the performance for a 1.4L; I'm sure he tests more than a few Commodores and rice-burners)Found traction control to be coming on harshly which then creates the feeling of axle tramp. If traction control is turned off car does not axle tramp but will spin the wheels very easily. Recommend going back to Volkswagen to have traction control & engine programming checked.
Anyway, no mention of torque-arm inserts, but he said since the TC is basically software I could try to get it reprogrammed (don't really like my chances with VW doing it). I went for a quick drive around Gembrook with the TCS off (haven't really done that before) and couldn't get any tramping, just some wheelspin on surface changes, which let's be honest isn't hard to manage if you're awake and have decent car control skills. I might shoot APR an email to see what they say but other than that I guess my best bets are to turn off TCS if I'm in a hurry, since today's drive convinced me that I'm much better at managing traction than the computer is (surprise surprise). ESP is still on, which is the main thing
More in regards to the original post, with speed humps and generally any low speed maneuvers (i.e. in heavy traffic nearing a red light), the DSG can be jerky. I find if I avoid slowing down too early and thus avoid having to accelerate gently in 1st or 2nd, I don't come across the issue.
