A warning has just appeared on the GTD about particulate filter. I know this is the DPF needing cleared. Is this a dealer job or just take for a decent run, if a drive then how long and what type of driving is best?
-
Highish revs for about 20 mins. I think it's in the handbook. How old is your car and what driving style does it get?
-
1800 to 2500 revs for around 20 mins on a warm engine, at a decent speed 5th (50-60mph) or 6th gear 65+, screaming 2nd at 35mph won't cut it. Have you changed fuels lately (from a usual kind?), or have been doing a lot of short journeys over the Christmas period if you weren't at work?
-
Cheers guys.
A lot of round town driving. Car is 11 months old.
It has been parked for about 2 weeks over Christmas and then my wife has used it on the school runs from yesterday morning.
Went a nice steady drive there in 4th gear and the warning has gone.

Tells you in handbook, car must be driven at continuous high revs, if you let revs drop the regeneration process is interrupted. One of the reasons I don't buy diesels. :)
-
Short journeys hasn't done mine any harm at all so no reason to not but a diesel! They aren't like the previous oil burners.
-
I think mine's a lot worse for regens than the previous 6 TDIs, I never once had a forced regen in the Scirocco 170, nor overrun of the fans following a journey. It's a regular occurrence now, but wasn't so much before my first service - things were definitely changed, more regens and extra thirst coincided with my first service.
Sometimes I wonder if changes were made because of some engine management parameters in place as a result of the Trevor box - like the car's ecu logged it running leaner than was the norm (because of the fooling the box does to the turbo sensor and common rail)?
-
That's why I wanted to come up and see you matt. Mine had an over boost error logged which I cleared before it's service and I'm wondering if this because of the box.

Any time you like Chris. But better make it this week or a few weeks time because the rear end bump is finally getting fixed next week.

I'm coming up to silver link tonight for half 7 if you fancy popping over.

Anytime but then. :whistle: I'm out on a pre-arranged drinking session at 6:30. I'll have to give the car a wash over the weekend before handing it over to Mill, it's filthy, and the boot is full of stuff I need to get in the house. Any other time you're over this side of the water? Should I get the laptop up and running the latest VCDS?
-
I've got a net book for using vcds now matt. Give me a shout when you pick the car up from mill car comic after its fixed.I could meet you before you had back to shields.
-
If you lads are stuck for VCDS I'm down Durham way if you keep missing each other.

No, they are worse than previous ones for short journeys... I've never been reminded to drive a distance long enough for regen to complete.... 49k miles in less than 14 months thou.
Short distances for a month or longer and it will likely as you to do a long journey so it can complete dpf regen it's been trying to unsuccessfully complete for a while.
If you do short journeys during the week but give it a good long run during weekend you won't see DPF light thou.
-
Disagree about them being worse than previous ones for short journeys. The tiguan I had used to bunny hop down the road with short journeys but the golf isn't bothered at all.
-
Mine seems worse for the same journeys (13 mile commute each way, mixed roads, very little congestion), but I think I drive mine quite hard (which can't help in the generation of particulates). In my previous Scirocco, I never had a forced regen in the whole time I had it, but it's a regular occurrence now, moreso in winter and especially after a change in fuel (not using the same brand twice in a row).
The GTD takes longer to warm up than the Scirocco did (which can't help in burning off the particulates) - my Scirocco was warm 7 miles into my commute, the GTD is warm 10 miles into my commute.
-
They are worse in a way that they don't passively regenerate (like mk6 and all other VAGs using same engines) as the exhaust temp was lowered, i.e. they are more dependent on active regens.
If you don't complete the active regen the light comes on where on mk6 you might get away with far fewer regens (certainly a lot less active ones).
-
They don't need to passively regen any more as they are different to previous VW diesel engines. I've never had the light come on yet and most of my journeys are short.
-
They don't not need passive regen, it's just not really doing anything passively..... resulting in about twice as many active regens on mk7 compared to mk6 ;)
-
They've moved the location of the dpf from the mk6 so it doesn't need the passive regens, so I was told. The mk7 does seem to regen about 800 miles or so no matter what driving you do. Its certainly different and something to get used to :grin:
