I want to check I'm not suffering from placebo effect and there is something wrong. All the below is in normal engine mode.

 

Long story short during fault diagnosis the dealer performed a throttle position correlation reset. It didnt cure the fault and showed up again. Subsequently leaking boost pipe was located and replaced. Another throttle position correlation reset was NOT carried out.

 

Now the following tends to happen

Select 4th at about 25mph

Selects 5th at 38-40

Selects 6th at 44 on anything less than a third throttle.

 

Coming down wont change from 5th to 4h until 32mph, its practically on idle before change, this happens all the way down with 4th and 3rd.

 

If under slight load the car will change up 2nd through to 5th by time I'm at 45, lift off and it will change to 6th. Previously I'd find myself having to lift off as I'd reached desired speed in say 4th, it just keeps changing up early.

 

Previously if in 5th and I flexed my toes it would drop to fourth now it relies on torque in 5th. Same for 6th and 4th, short of applying half throttle it wont change down.

 

The first 1/4 of the throttle feels numb, almost like eco mode. For it to change down I'm almost having to apply half two thirds throttle.

 

Due to the way the car now behaves I'm finding myself in 4th at roundabouts 5th during slow speed (33mph) bends and during inclines where as car would previously change down it's now relying on the torque with a slight increase in pressure on throttle.

 

All of this I'm sure was not the case. On top my commute would normally see 38mpg with no trying and no traffic, just a nice forward planning commute. The same journey I'm seeing 33mpg. I can get 38 but I have to try o so hard. 

Generally after two tanks I'm down from 36 to 32 average and now 330 a tank instead of 365miles.

 

If the above is normal then maybe it was wrong in the first place. If the above is out of character in your experience then I feel a little bit better in myself that something is wrong when I contact the dealer......again.

My previous car the same combination VRS/TDI/DSG never seemed to be in the right gear and always lugging a higher one than I wanted. And S-mode was the opposite like I was on a race track. Sold it. 

Sounds like something's up with yours. Why not take it back and give them the exact same description - if it was me I'd give them the description in writing, instead of passing it on word-of-mouth via the service manager.

Sounds like you drive with quite a light foot? The day does adapt a little to the way you drive. Not 100% sure on how exactly but maybe it's just that it's got used to you and it's doing what it thinks you want. You can reset it yourself or get a garage to do it and see if it makes a difference.

A pedal box has helped my TDI keep in a better gear rather than labouring a high one.

Had the car for 2 years and never any problem with the dsg, I've always found it ideal and never has it wanted to be in 4th or 5th or 6th so early.

Its since this TPS reset that it feels like this. Taken the joy out of driving it. A prod on the pedal in 6th at 44mph will see it pull and not change. Before it would have been in 5th and dropped to 4th. 

 

I have seen he dsg reset thing. My thoughts are that this correlation reset needs doing again now the car is actually running as it should. Back to the dealer for round 5 I think.

Sounds normal behaviour. The DSG relies on your throttle input. If you put your foot down it will drop down the gears to the right one for the right speed etc. Equally if you don't use the pedal that much it will go up the gears very quickly for economy. 

The throttle pedal is deceiving as it is incremental and designed for economy. It gives you a delayed /vague response but you can get that changed to linear if you have vcds or obdeleven. You can also check the control units and easily adapt your throttle aswell yourself.

No access to vcds or others.

I suppose I'm just frustrated at the fact my driving style and input has not changed but the feel and response of throttle has along with behaviour of dsg.

 

I'll see what dealer comes up with

I would ask if they have updated any modules whilst it was in. I had my DSG serviced and an update was applied. It now semi coasts when off the throttle in normal mode and it didnt do it before.

As above, the DSG reacts to your 'Driving Style' on an instantaneous basis, it uses the speed and aggressiveness with which you use the throttle to adjust the shift points. It does not 'remember' your driving style.

 

Your car is MY15? Have you had it from new? If not it is not out of the bounds of possibility that a previous owner has done the 'throttle mod' VCDS tweaks and that has been reset to standard by an update done at the dealer.

If that is the case the dealer will not be able to do very much.

Yes MY15, not had from new, its possible previous owner had something done albeit this would be the only thing done as I've had quite a few things added with help of a member here.

 

I hear what you and above are saying in relation to how dsg works about not remembering but I've not had this issue for 2yrs 22k and it has become apparent after this throttle position correlation reset. 

 

I've spoken to dealer today they want to ask a tech. I cant help but think that the correlation was done to fix a fault. A fault that returned and was diagnosed as a leaking boost pipe, in reality the throttle reset never needed to be done.

 

I'll research the throttle mod.

 

Thanks to all for taking time to reply
