Not total, but more. Talk to your tuner, they can tweak it for you.
P1004, P1005, P1006, and P1007, Are Torque Difference Cylinder X: Limit Value Exceeded. Otherwise, the tune is pushing what the ECM thinks is the limit. I get them every now and then when I am pushing it on the highway in the higher gears. Supposedly it can be tuned out, but isn't hurting anything. I clear them and move on.
I went back to the tuner and had it reflashed and don't get them anymore.

ok guys I need some help. I got my Rawtek exhaust on and my Stage 2 Malone Tune and everytime I start the car I keep getting a P203A code, Reductant Level Sensor... I heard there is some stuff to go through VCDS and reset some stuff like SCR reset etc.. Could someone please show me the steps to get rid of this code.. Thanks

Thanks to all here for this thread and coffeemade your wisdom has convinced me that stage 1.5 with the dsg tune is going to be the way to go!

powerstroker, it sounds like you need to get back in touch with Malone... he may have missed part of the DEF system when building your tune.

@powerstroker, I am going to guess you had it tuned before you installed the exhaust. If so you need a new flash to be better suited to your exhaust upgrade.

My Malone tuner is awesome, he's about 2 hours from me but worth the drive each time.

Got my tune updated, no more CEL but I have noticed that the DEF nozzle is still injecting urea. Is it still suppose to be doing that? I cleaned the area up on the exhaust and see what it does with the new tune.

Malone/Rawtek MPG Update

Long term (10k miles) I've been averaging about 34-37 MPG with all local driving which is about the same as before the mods. However, I took it on its first highway trip last weekend and was surprised to see the average 'indicated' MPG running as high as 54 on one leg of the trip. Overall I managed about 44 MPG out of the tank with about 60/40 highway/local miles (696 miles/15.9 gallons).

I'm thinking this is a little better than I would expect from a stock setup?

One interesting observation, on the way there I averaged ~44 MPG but on the way home, on the same tank of fuel, on the same roads I managed 54 MPG door to door (as indicate by the dashboard lie-dicator). Only variable that changed was a big temperature variation. The trip home was about 30 degrees warmer than the trip there (50 vs 80). What do you think? Can the temp really make this much of delta?

That's about the same as a stock setup in my experience. As far as I can tell, people with modified Passats are not seeing mileage increases - it's about as efficient as it gets right out of the box.

Mileage fluctuates a lot with temperature, wind, rain, speed, etc., so it's hard to tell sometimes. Some trips can be in the low 50s, others in the low 40s.

My short previous commute was 5 miles and averaged about 32 mpg. My current commute is 35 miles and am now getting about 42/44 mpg. On longer trips greater than 200 miles have returned 53 mpg or so. Ditto for conditions. Mine seems to do much better when it is over 70 F. My 2006 Jetta seemed to like it better around 60 F.

I don't understand why, but air temp seems to make a big difference in mileage in these cars. I get better mileage with an air temp of 80dF with the AC on (57mpg) then I do at 60dF with the AC off/windows closed (54mpg).

Well, yes temperature change is going to make a big difference in mpg.

Hence, reason why you get better mpg in the summer than winter.

+1 on that, I cannot prove it but I swear the car adds a post injection to keep the exhaust system warm when its cold outside- On a long road trip with a few hundred miles of flat ground I went from 73F and overcast to 55F and rain (cold front) and as soon as the temperature dropped my MPG went from 48MPG @ 80mpH down to 41MPG and EGT1 went from the 700's up to 950F

Interesting, and might be the case. Do the tuners get this feature out with the dpf delete tune?

At operating temperature, colder air is better for engines. The reason then for the MPG decrease in the winter is due to the winterization of the fuel to prevent gelling.

This is why you get your highest MPGs in the Spring/Fall: colder air, still able to achieve operating temperatures quickly, AC off, and no winter fuel treatment.

Actually I get the highest mileage in the heat of the summer. With my 12 Passat I get better mileage at 80dF running the AC than I do at 60dF with the windows closed. This was not the case with my 02 Golf.

Since I live in the south, winterized fuel doesn't hurt that much, so I don't see huge swings between summer and winter mileage. This winter was one of the worst and at most I saw a 5 mpg drop. Now that the heat of summer is here with 90s across the seven day forecast and ac on all the time, I'm probably seeing a couple of mpg drop in city driving. I had a 97 ford minivan that got better mileage with the ac on than without.

Any thoughts on whether a DPF and EGR delete is the answer to the turbo failures??

Nothing conclusive from all the reading I've done. However, the lowering of exhaust temps couldn't hurt by removing the DPF. It may possibly reduce the heat spike. Until they fully diagnose what the main cause if the failures are, everthing else is all speculative information.

I like the idea of the delete but I think that video has a little bit too much rasp for my liking. Like a little more turbo whistle instead. I really do look forward to the day I can do this mod.
