Title: DSG + hot weather = :-(
Post by: rich83 on May 24, 2012, 04:55:34 pm
Hi everyone.

IT'S BOILING!!!!!

Just driven into Birmingham in start sop traffic and twice the box failed to take up drive in first gear. Also my car stalled once.

I opened the bonnet when I parked up and the engine was a million degrees.

I'll VCDS scan it at the weekend, but has anyone else had this happen?

Scared.

No, Rich, never had anything like this - when in traffic are you dropping it into N?

No Dom I didn't. Just left it in 'M' and went to set off and it didn't want to move. :-(

I used to do this in the old automatics as it felt like they're always pulling against the brake.
I don't do it anymore with the DSG box, but then I never drive in 'm', I always drive in 'm+'.
Any issue with th DSG box to keep putting it in 'n' every time u hit traffic??  :confused:

no issues that caused me to do this but in the manual it says treat it like a manual gearbox i think, where as if your at traffic lights take it out of gear and the same in traffic...just the way i drive

i vaguely remember reading something on audi-sport that says you're not meant to do this, but i can't find the thread and apart from the extra wear from changing gear more times i can't think of any reason why it'd be a problem

Are you sure your not getting confused that your not ment to run in neutral whilst in motion.... As your then not pumping oil around the Dsg gearbox..

I always drop into neutral in traffic. D for town crawling, and manual on the Dsg shifters all other times.

well i've found a post on another forum from T_T that contradicts what i say. there's no doubt T_T is a valuable and knowledgable member of the forums, but tbh most of the stuff i read smacks "alarmist" to me

put it this way - 99% of people who drive a DSG will not know it's any different to any other automatic. if VAG designed a gearbox that looks to the untrained eye like a torque-converter auto gearbox but needed driving differently or it'd wear it's clutch packs out they would have designed it badly and gearboxes would be failing left, right and centre and they aren't.

i don't for a second think that VAG engineers are that absent minded, so i'm happy leaving it in D when i come to a stop in traffic. if i'm stopping long enough to consider putting in it N i'd turn the car off anyway.

the only issue i have with this is that at night time you dazzle the driver behind you with your brake lights, but if you use the handbrake the car strains against it for a second before settling down and i don't like that either. (that is also proof to me that the car dips the clutch when stopping - because you can feel it doing it if you leave it in D and put the handbrake on.)

i'd never coast in N in any car lol.

I'd personally start pointing toward the mechatronics unit, just keep an eye on it and see if it starts repeating it on day's with normal outside temps. In start stop traffic they shouldn't get that hot as the gearbox isn't really doing a lot although the coolant from the engine is heating up more when stood still so isn't cooling the dsg as much. However I would just monitor it and if it gets worse, I'd say it's the mech unit.

am i right in thinking you leave the car in "D" and put the handbrake on rather than your foot brake?

no that's what i'm saying - i don't use the handbrake. i know in terms of rear end shuting and courtesy to drivers behind me it's not the best practice, but on my car at least when you're stationary and you put the handbrake on the car strains against it for a few seconds before settling down.

anyhow i've read a bit more of what T_T has written on that other forum and he's said that apparently it's ok to leave it in D for "short periods" as this is what VAG advise - but no mention as to what duration a "short period" is.

here's the thread:

http://www.r32oc.com/general-chat/11099-how-use-dsg-gearbox.html

the long and short of it is that i don't think rich's driving style has anything to do with the symptoms he's experiencing which, to me, sounds like a mechatronics fault. if his car is around '07 then i believe he's in the right age band for the faulty batch that went out and failed.

I always drop it into neutral when stationary for any length of time in traffic

Wow, that's an interesting thread!!!

I will have to drop it into 'N' now every time I'm in traffic or the lights - but living in London, won't I wear out the DSG box from all the changes??   :surprised:

Check dsg oil level as well, did see a car once that had a dsg oil leak as the dealer that did the dsg oil change forgot to re-install the little tube under the drain plug and the sump nut leaked, less oil = more heat.

Thanks for all the responses.

On my way back home tonight (100miles) the car behaved itself... no issues with the 'box at all.  :stupid:

Ill see what the scan says at the weekend.  :happy2:

Take it to VAG specialists  :wink:

Yes... You really must give me the number of that place in harrow wealdstone....

NOT!!!!!!!

Just google it  :stupid:

I dont need to... i know where it is. I lived in harrow for 4 years  :wink:

Yeah right keep the act to yourself thanks

Whoaah there kids, calm down

Sorry not had any symptoms the same, drove 220 mile trip yesterday and it averaged 25-28c and no issues to report, steady A roads, Motorways and crawling along in traffic 2.5hrs each way  :sad1:, wish Norfolk had motorways!


I hope it was just a one off glitch Tamiyoman, been out today and no problems at all.

Im in Norwich in a couple of weeks....  :happy2:

Yes hopefully it was a one off, was over at R-Tech yesterday and they mentioned you were there not long back, bit of a trek acroos country for me but worth it  :happy2:

Norwich is OK, nice enough city  :happy2:

Rich when you get it on cds set the measuring blocks for the temperature and pressure when held in d on the brakes the temp at the clutch pack it shoots up.

could be due oil and filter change if your cars done 40k and every 40k after that
