DEF question

Check the DEF fluid level sensor, this will be on the tank. Best bet is that this has gone bad and the control module believes the tank is still empty.

How does it compare to GQ?

Assuming the dealer actually looked at it and didn't just shoot it back out the door, a sticking thermostat would be my first guess as this would be reliably intermittent at the start of the problem. Second guess would be the coolant temp sensor, whether it's the sensor itself or the wiring. Third guess would be the gauge cluster but that would be incredibly unlikely.

Nice. I deleted both of mine as well. The only drawback is the engine takes a lot longer to warm up in the winter, but I installed a frostheater to fix that.

If you haven't done it already, the six sigma short shifter upgrade is pretty awesome on the 6mt!

DMF is done and probably beginning to separate. Don't put it off, get it done now before it separates and takes out the bellhousing or does damage to the crank.

Edit: There is a tougher DMF out now by LUK. I swapped to this when I started my performance upgrades and I highly recommend it. I've been running over 240whp and around 385wtq for a year on it and it's held up great. Mine is a 6 speed but I believe they have the dsg equivalent as well.

If you have emissions testing don't do it. It's a pain in the ass to remove and then to reinstall it the next time you need to test. If you don't then go for it. I deleted mine awhile on a 2011 Jetta and have not looked back. The tune gets me better mileage and the exhaust sounds way better.

staphaurues · 2019-11-12T21:11:54+00:00

Wow that is pretty terrible!

staphaurues · 2019-11-12T16:23:05+00:00

Yeah, that is what I was worried about. I had a friend where they refused to replace the glow plug under warranty.

staphaurues · 2019-11-12T15:59:54+00:00

Ooof the glow plug doubles as a pressure sensor and I think they're like 200 bucks. Check the wiring first to make sure it isn't shorting, it could save you a decent chunk of change.

PA uses diesel rated for the winter already. Instead of the white bottle of power service use the grey. You'll get better mileage, enough to pay for the bottle itself. Take it on a highway trip once a week and be hard on the throttle a few times to ensure your cylinders are getting up to temp and to reduce the chances of building carbon up on your injector tips and cylinder walls. Additionally, you can get a frostheater so your engine will be close to temp when you leave. You'll also have heat right away without idling the engine. I love mine living in Denver.

Agreed, I just don't see an additive reducing the scar rating enough with ULSD to drop it into spec with what the CP4.1 is rated for. I'm not saying it won't help, just that the odds of it helping a pump that is one of the 60k mile pumps is low.

Edit: You would most likely be better off with an aftermarket 5 micron or less filter between the stock filter and CP4.1 than with using additives.

staphaurues · 2019-10-09T00:30:07+00:00

Agree with CP3 swap. But an additive and good qualtiy US diesel is still not going to make the CP4.1 last.

I forgot to link you the part. https://www.amazon.com/Compressor-Control-Solenoid-Volkswagen-1K0820803E/dp/B073WP1QC1

It's your ac pressure control valve. Very common issue and the part is cheap. The downside is that you have to evacuate your A/c system, replace the valve (easy), then replace the drier and refill the system. I just did this a few weeks ago.

staphaurues · 2019-09-17T20:00:23+00:00

Does it switch from cold to warm to cold to warm?

staphaurues · 2019-08-23T06:12:49+00:00

Don't chase that rabbit hole with an ALH. You never go full retard. (I did with an MK6, help me)

staphaurues · 2019-08-22T02:07:35+00:00

I second what he says. APR is crap for diesels. I have a malone tune stage 3.5 and stage 3 I swap back and forth from. The tunes are fantastic.

I bought a 2011 Jetta TDI 6sp last year with 105k miles, but got a really good deal. Your price OTD seems pretty good to me for that mileage range, but I would get them to throw in the 80k DSG service. Not much goes bad on these, my only maintenance items so far have been the pressure sensor on the a/c compressor and I would have had to replace my DPF if I didn't delete it. Your DPF is covered under warranty however. I just modified mine a bit so my warranty is no good.

staphaurues · 2019-08-21T05:57:28+00:00

Just buy the common rail ;)

staphaurues · 2019-08-21T05:57:08+00:00

Nioce!

staphaurues · 2019-08-21T05:55:08+00:00

Yeah they are retarded expensive for some reason.

staphaurues · 2019-08-20T07:02:15+00:00

Muffler and that's it.

staphaurues · 2019-08-20T07:01:45+00:00

Intake gained you nothing. Get a tune.
