Whilst I (and the wife) absolutely love the GTD, the wife made a jokey comment last night, that when I pulled off the drive yesterday morning, the car sounded like a taxi. I had a listen tonight, and certainly compared to my 140ps Scirocco I had before, on tick over, the GTD, is much louder and more diesel "tappetey" like than the Scirocco (which really impressed me from day one with how quiet it was on tick over).
Is this just a newness thing, and do you think it will quieten down ? Anyone else noticed this with theirs ?

Is that just the sound actuator? Even in "normal" it's doing a little something to boost the interior noise. Mine seems as quiet in "eco" as the scirocco was in "normal". It's more likely to get quieter over run in than louder.
The trouble with comparing to the last car is that you are comparing the tight new car to the well run in old one rather than remembering how the old one was in it's first week.

I'm talking about the car at standstill Monkeyhanger, just on tick over on the drive.
Inside whilst driving, its much quieter than the Scirocco (expect when I have the Dynaudio turned up :evil:)

Nope, don't think so. Maybe the 170 was a bit noisier than the 140? :undecided:

Had my window down last night briefly and noticed the engine sounded quite taxi like. Was wondering if it is noiser when its going through a DPF regen?

It will if it's going through an active regen rather than a passive one then it'll sound a bit taxi-like because the idling revs are at 1000 rather than just below 800. My first active regen came in at 65 miles!

Any other way to tell (like do you get anything on the MFD?). Thinking back don't think it was a regen or anything because my Stop-Start was working.

No messages to let you know. If it is doing a passive regen the idling will be normal but the stop-start won't work, you won't see much of a mpg penalty. Active regen and you will see the idling revs increase as well as the stop start not working, and a very noticeable fuel penalty.

Hmm..Can't say I've had a regen yet then and I've done about 400 miles. I'll keep my eye out. How long does it last?

Depends how you're driving. If you're on dual carriageways doing 70+ mph for a lot of your driving for at least 15 miins a session, you've probably done all your regens passively in a fraction of your journey and not even known about it. If you've been tootling around the doors and not had a regen within 400 miles then something very odd is happening.

Ah to be fair the vast majority of my mileage has been dual carriageway (a19 bane of my life). That'll be why then.

It'll sound like a taxi because it is a diesel.
Whilst they have done some clever stuff to address nvh issues with diesel powered cars over the years, because of the compression ignition, they'll never get rid of that characteristic diesel "knock" entirely...
-
I can't get over how quiet my GTD is, it's the quietest diesel I have ever driven
-
Yes, very very quiet Gordor sat inside and when driving, can't fault it there. I was more referring to standing next to it on a driveway with the engine on tickover. I know its a diesel and therefore they make diesel noises, but certainly my Scirocco CR TDI lump was quieter.
On a positive note though, now that I have some miles on it, not only is the economy improving hand over fist, but the engine seems to be getting more and more quiet as well.
-
I've not tried the standing next to it test yet, but I was driving an A1 while waiting for the GTD to arrive and it is so much quieter than that. Mind you, I am driving like a nun at the mo :cry: On the bright side I actually got the park assist to work today...thought I was being a numpty and couldn't make it work before so well happy.
-
Sorry for my ignorance, but wtf is a 'regen'?
Sounds like something Doctor Who does... :smiley:

Hey Gordor - could I ask what's your impression of the Park Assist so far? I've got that coming (strictly for the Mrs mind you :grin: :grin: :grin:).
-
To be true, the park assist is a bit of a gimmick (first time I have specced it also) I too might have bought it to protect the 19s from the good lady, but it would have driven the car into a pillar in the multi-storey last Thursday if I had let it :sad: :sad: :sad:

Modern diesels to cope with ever more stringent Euro emission laws, now have to be fitted with DPF's (diesel particulate filters). These filter out all the harmful soot deposits from the exhaust system, which is why modern diesels don't leave a trail of black smoke when they accelerate.
Trouble is, to effectively burn these soot by products, the DPF has to be at a critical operating temperature band (which is very high). If you use the car everyday for reasonable journeys, then the DPF will attain temperature and the soot deposits will be burnt off. The DPF can self regulate itself and constantly measures the soot level contained within in. It can only hold a finite number of grams worth of soot, and when it feels its building up, the ECU will instigate a regeneration (or regen) cycle. This can with be passive (I.e unnoticed to you, and taken care of by the ECU during the normal driving of the car), or forced or active.
If however you do constant short journeys, the car is unable to burn the soot using the passive regen method, as the DPF temperature and length of journey isn't sufficient to allow a passive regen. In these instances where the soot begins to build up, the car can at any time instigate an active regen. With an active regen, changes in the timing and fuelling characteristics are deliberately altered to raise the exhaust gas temperatures, thereby heating up the DPF. However this method will have an impact on fuel economy and will raise the revs and you normally smell the increase in temperature from the engine bay. If the car still can't perform even an active regen (journeys are far too short), then the ECU can switch in a dash warning light and it then becomes a dealer matter to force an active regen in their service bay. Note that this isn't covered under warranty and would be a chargeable exercise.
That's the reason dealers are supposed to ask what sort of mileage the car will be doing before selling someone a Diesel, as constant too short a journey (I.e. just the school run for instance), will block the DPF very quickly and even a dealer active regen might not be able to recover it resulting in a new DPF at a cost of well into 4 figures.
Hope this helps.

that's not the fault of the park assist. nothing wrong with system and it's far from gimmicky. it says before in the mfd to check and your always in charge not the car and if you think it'll save your alloys think again. if the car in front or behind is parked with a wheel touching the kerb the yours will too as it uses the other cars as reference points.
-
That's me told :wink: :wink: :wink:
You're right about the MFD but I was a bit surprised it didn't spot the 2ft x2ft pillar tbh
-
Sorry Gordor if my reply was a bit terse :laugh: it should pick up obstacles but sometimes it either gives you a false beep after its picked something up or sometimes it beeps if something has slightly obscured the sensor.

I did wonder whether the extra side sensors would detect the average kerb or not - guessing not...
-
if your parking yourself then they will beep for the kerb depending on height. if use the park assist it uses the other cars as reference points not the kerb.

Cheers mcmaddy. Looking forward to trialling it myself.
