Default 2009 TDI-specific issues

Thank you for the reply,kindly DRDAWG. That price is sure an indication that there are few,if any, free lunches anymore. Back in the day (about 2 years ago) I wailed about having to drop ahout $80 on a whole set. Ah, them were the days!!

Thanks!
^^Does anyone know the answer to my question that I asked a couple weeks ago?

No, no modification is warranted, the DPF is a fickle and very costly creature best tended to by mother VDUB. Screw it up by somehow remapping things, and you may be out 3 or 4 large.

Even VW is reluctant to modify anything. DSG shift programming for example.

In a way, I suppose a more general version of this question (i.e., "Can/should I modify the X?") should qualify as a FAQ here and get added to the list in post #1. The reasons I hesitate to do so are: (1) These cars are too new for anyone to have any solid, fact-based answers, and (2) My own personal answer is merely my opinion and doesn't deserve to end up sounding like a fact.

In case you're curious though, my own personal opinion is this: The '09+ design is so highly computerized, bristling with so many kinds of sensors we've never seen before (just one example: pressure-sensing glow plugs), all of which the ECU relies upon to make its decisions, there's a very high probability that any engine or drivetrain mods will have effects on ECU inputs that will deeply confuse your computer, throw a bunch of codes, and perhaps cause Very Bad Things to happen. As a rule of thumb, this is not a car suitable for modding, except for trivial stuff like adding a skidplate. For more functional types of mods proceed at your own risk (and, of course, kiss your warranty goodbye!). If one accepts this argument, it then follows that no modifications are "necessary".

Thanks for all the input guys...I wasn't sure if this new engine is expected to have the same issues with clogging of the intake system over a long period of time like the older engines do. I suppose this new high tech engine is both a blessing and a curse, depending on what you want to do with it.

Great thread. Here's a question to keep it alive.

Why won't my '10 JSW rev to redline? I'm trying to use the entire powerband as suggested in the break-in procedures, and the engine only revs to 4200.

My guess only: you've got a DSG => it will shift for you prior to getting to high revs/red line...?

Have you tried to redline it in Sport mode?

I forgot to mention that I tried all modes including manual. I got the numbers wrong also, it'll rev to 4400, not 4200.

All,

Yes, I have the same scenario. I like the transmission, but it does shift too early for my preference. I thought I may need the firmware/software upgrade, but my mfg date is August 2009.

It won't matter which shift mode you have it in.

Take the car out, get started rolling at around 30 mph, stick it hard to the floor and hold it. If it shifts at or near 4500 you're fine. Just remember to really bury the pedal. I think there's a 'kick-down' switch at the the carpet.

When the battery dies, you buy a new sensor as they do NOT have user serviceable parts. Sensors can be bought on eBay or vwwvortex. Cost around $80 - $100.
Older post, I know. But I was looking at the owner's manual on my 2010 Golf, and it says that the TPMS sensors should be replaced at 6 years regardless of mileage, per the service schedule. So you're right on the money with your 5-7 years recommendation.
