Scirocco Central

Hello folks,

Anyone had any change in behaviour of their DSG since service? Not sure if they reset it back to defaults. ps. this is not a Scirocco but my wifes Polo GTI with the 7 speed box. Since it was serviced last week I seem to be urging it to change up, and it changes just before I get fed up and manually override it, particularly in the lower gears 1-4. I am hoping it will re-adjust to our mode of driving but there is definitely a change in characteristic since it was serviced. Anyone had a similar experience?

Cheers.

There is a 7 spd DSG ECU firmware update being applied. It wouldn't normally be done at a service unless you had reported a problem. The changes include quicker shifts between gears and change of gear shift points.

Cheers RW1 for your prompt reply, that is interesting. We had not had any DSG issues, the only bugbear being when it can irritatingly change down un-necessarily on inclines, prompting an override.

I asked the dealer if there were any firmware updates generally, to which they replied, no - there are no recalls outstanding. But yes - I am hoping it will re-adjust as the box seems slower to react now which made me think they have reset it, its not so much fun to drive

Car is a Dec 2010 so only a year old, would this firmware update apply to a car of this age do you know?

Cheers.

I get that effect on inclines, triggered by using the foot brake combined with the car tilting nose down, which then puts the gearbox into engine braking after about 3 seconds. Found it useful as its what I would do with a manual gearbox on an incline.

"Dec 2010"... In which case the updates are built in.

If they did perform a reset of the DSG, then there is a whole set of drive sequences required which would take around 30 mins to complete to educate the DSG. If the adapations weren't completed by the dealer, then it re-learns them as it comes across the open parameters that still need to be set. As it gathers the data, those settings picked up and stored.

Suggest you take if for a quick drive on the motorway and do some drive sequences to exercise and show the DSG, nothing exceptional, just so the DSG see's something more than town driving. It needs to see 2,000 - 4,500 rpm in all 7 gears for 1 minute in each gear setting. Not acceleration but just an engine speed in a gear within the above rpm range constant or varying within the range for 1 minute minimum (Not hard accelerations, more cruising). You will have to use the manual side of the gearbox to do this. And the DSG must see all accelerator positions (any gear), ie idle through to full throttle and kick down switch at the far full throttle end of the travel.

Failing this rectifying..... take it back!

Cool - many thanks indeed for the useful info there. Not sure if you have found this situation, there is a short steep hill where I live with a junction at the top, when going up the hill, the box kicks down and I promptly override it again. At the top of the hill, the box has normally returned back to D1 (full auto), it is then tardy when pulling away going into D2, D3 etc. If I have not overridden it, generally it will change up quicker

As I mentioned we have had the car a year but as I am chopping and changing between my (manual) Scirocco and the Polo, I am still learning about any quirks about the DSG. I know we running on 95RON petrol at the moment, again - maybe the service has disturbed the ECU slightly and it is re-adjusting and not giving us the optimum performance that I was used to pre-service, not sure.

Not had that but, in that situation I tend to use the hill to uphill brake without brakes or gearbox override. Maybe the timer for the manual override hasn't fully expired . Despite being back in "D" mode.

Also my DSG would kick down on inclines until I sorted the spark plug gap as per my other topics. Now I get the odd time where the opposite happens, ie. its in a higher gear to pull up the hill and doesn't want to change down unless I push the throttle a little more than I would expect to use (not floor it). Then it jumps down 2 gears! Bit like a flat spot effect. I don't get bothered cos as far as I am concerned, the throttle is the control while on the move as I feed in a throttle setting I want. The DSG just does what is necessary and its not always the same. You don't press the throttle the same way as a manual gearbox. I feed in the throttle over 2 - 3 seconds to the point I want. The throttle then moves as per the engine ECU's instructions, not your right foot. Stabbing the throttle acheives a poorer response on mine.

There are Polo GTi specific engine ECU updates around the garage may have done to the Polo engine. If so, the ECU should have settled down within about 100 miles.

There are reports I've seen which suggest toning down happens with the engine ECU updates.

Many thanks again for that, I appreciate your detailed write up. Yes - I think your right about the timer not having fully expired. It is literally pretty much as soon as it goes back to 'auto' mode that the box turns 'lazy' for the next upchanges.

Car has still only done about 45 miles since service so I think really needs a bit of a run (as you have described) to settle things back down again.

Just an update here, after a few days the DSG does seem to have settled back down again following a scheduled service. Certainly taking it out on a bit of an extended run has got the box back to more how it was pre-service.
