DSG: Problems, Questions, Likes and Dislikes

[wai]

Now here's an odd one.

There is a street in Chatswood that is very steep. No problem driving up it, but when I get to the top and stop, on getting moving again, the DSG does not want to change up for quite a few seconds. It is not slipping or anything like that, just that it takes around 5 or more seconds of driving before the transmission will change up, no matter the speed. It does not redline but the rev limiter does kick in and stop you over revving the engine.

There are no alarms or other indications.

This has now happened twice when I have had to get to a meeting in Chatswood.

For those interested, this is driving south on Edgar Street and then climbing up to Centennial Avenue when I have to stop because of a spoon drain. Then it is a left turn into Centennial Avenue and now the transmission will not change up for a few seconds.

It is the combination of circumstances, because I drive up similar slopes elsewhere without any issues. It is almost as though the slope is causing issues after coming to a complete stop and then starting off again. I don't lose drive, just that it won't change up for a few seconds.

As I said, there are no alarms or other indications so it is doubtful that any faults would be logged.

So change up using the paddles ???

Then, to get back to full auto, either let it do itself, or hold the right paddle in

It is a manual gearbox after all

You need more power to go uphill which is why it will hold the gear longer, nothing too unusual about that, although it can take you by surprise sometimes. Sometimes after driving in manual mode and going back to D, it'll hold first gear longer than I expected, which makes me panic and think I'm still in M, which used to make me shift up in Neutral, which makes you panic just a tad more and look a bit silly :p

The thing is that it catches you by surprise because it is just this particular combination of roads, slopes and stops that does it.

By the way, it is operating in full auto mode.

The problem here is that when I come to a complete stop, this is at the crest of the slope and the road I turn into is not at all steep. It goes up the steep slope in D5. WHen I come to a stop at the top it drops back to D1, but then changes up to D2 and stays there until it figures things out. Once it has done this it is quite happy to go up into D3 or even D4 at the same speed and load.

Ah well, they all have their quirks. On my Torana I had to manually change the auto down into 2 when making a left turn near my house because of the change in slope, otherwise the transmission would flair not knowing which gear to select. At least eh DSG holds one gear.

It just catches you by surprise and then it is a case of trying to respond. In both cases I have been caught out and by the time I put it into manual mode to change up or even to put it into S, it had resolved itself.

A quick poke on the gas pedal then backing off usually sorts it for me.

sounds like "hill-hold" to me. i've got that feature on the RS. on an incline, it will hold the car for 2-3 secs before the car moves off.
gives the driver enough time to hit the gas, preventing the "rollback".

though i don't know if this is the same thing on the golfs.

the golf's hill-hold is the same, but the situation wai is describing is after he's climbed the hill, it still hesitates to upshift.

to me it sounds like the car put itself into a low-gear mode for the hill, and took longer than necessary to realise there was no more hill.

The problem is that when I come to a stop at this particular intersection, the car is level. Having said this, it could well have something to do with the detection of the incline.

I suppose it is a by-product of the complex control systems, and comes down to a case of the the particular combination leaving the system believing the car is still on an incline and needs to remain in the lower gear.

I will get a chance to test it again as I make trips to the Engineers Australia presentations generally monthly. Next time, I will try and select manual mode before I go up the hill and see if that changes things.

Probably like the Oprical Park Assist sensors and controls. It can be a touch annoying because if you are trying to get out of a tight parallel parking situation (the other drivers have not maintained the 1 metre separation), you reverse back until you get the rapid beeping. You put the car into drive, but the radio display and beeping carries on for another 5 or more seconds. Maybe VW do not want systems switching in and out too quickly so build delays into things. Then along comes a particular combination of circumstances and you get odd things happening.

[Ryan_R]

Yeah, the car has a lot of sensors, but unlike you, it still doesn't have eyes to see ahead, hence the delay. I guess that's what you get when you have techonology that tries to be smart and adaptable.
