If I were to install a downpipe on the mk7 and not tune it, will my cel trip. Also if the cel trips is there any damage long term to the car having it on and second if I go to the dealer will I void warranty with a downpipe.

View 10 RepliesWe are in the process of taking off the downpipe of our R. We can not figure out the trick to getting the front lower bolt of the downpipe. For that matter we can not even see the damn thing. Do you get to it from the top or bottom?
View 13 RepliesSo I just installed (well Strasse Autowerks did) my ECS downpipe with high flow yesterday, i have an 2010 GTI Unitronic 1+ and i've been using the car for an hour without any problem and then after that hour the check engine appeared and stays on in my dash.. some guy told me its normal because i have to upgrade to stage 2 so the error would disappear is that right??
And while being here i was also wondering, I'm going to have an intake later next week but what else do i need as equipment for the car for that upgrade?
I Put my stock downpipe back on while having a CEL... never got the stage 2 flash. I can t reset the CEL it keeps coming back on. Do it will reset itself eventually or do I have another problem? It is the cat code I forget the number.

View 10 RepliesFor those of you who have the 42 Draft Downpipe, I have a weird audible vibration during acceleration and I'm assuming something isn't mounted 100% correctly.
I remember a while back I saw a post about something similar but search is failing me at the moment. So what was the resolution?
So I recently bought a GTI and started to fix a couple things. It has a P0420 code so I bought a new downpipe to install. Noticed the stock one was missing 1 of the nuts and the stud had broken off. How get this out? Do I need to remove the turbo? Looks like I do need to remove the turbo to use an extractor set.
View 7 Replieswhen I bought my 2003 gti 1.8t it had a small exhaust leak, I decided to investigate today and found that the downpipe flange and turbo flange was rattling around, there's almost 1/16" of play and it's making a rattling noise. I can't tighten the nuts on the studs any more but that might just be from them being seized in place. I'm getting a new gasket and studs and nuts and hopefully that will fix it?
View 3 Replies2003 Golf GTI Turbo... New to VW, I'm a jeep guy and bought a GTI for my wife to try rally cross in. It had some problems that I knew about when I bought it, had to replace CV shafts, control arms, fix broken trans mount, etc. I'm on to the last piece of the puzzle now.
The expansion joint on the downpipe from the turbo is basically exploded. Not a big deal, just buy a new downpipe and biky everything together right? Not so much. Bought one the other day, it showed up and has 3 bolts on turbo side, mine has 4.
When I look at the other stock turbo downpipes, it looks like they have 3 bolts as well. What's going on? Did the previous owner put a different turbo on this? I just need the damn downpipe, but can't figure out which one to order.
I just had a new downpipe installed and now I am getting a horrible scrapping noise when coming off a dead stop. I got under the car and looks like the downpipe is touching subframe heat shield. My question is should i take it back and have them make some clearance or is there a quicker solution. New downpipe and subframe heat shield.
View 2 RepliesAC would blow cold from time to time and not work other times, I tried a recharge and it did nothing to fix the issue so when I took it in for the 40k service I had them take a look at it and they told me that the tuning of my ECM is causing the AC to not work properly! I have the UM tune for flex fuel.
View 1 RepliesI have the VF-stg II s/c kit with a UM E35 tune, it seems to have a problem mapping or something when in Launch control mode. If I don't turn off the Launch control before I start driving it will cut rpm's around 3k then kick back in after it thinks for a second, also the engine light comes on/ flashes when the power cuts out. It does this especially hard when going from first to second. It does have no lift shift, but not lifting off the gas when shifting doesn't stop the engine cough.
Should also mention that the launch control doesn't seem to work all the time, only once in a while, will the engine max the revs at 3k on start like it's supposed to when LC engaged.
Currently I have a warning light for Performance malfunction in cooling system, which is also confusing because I have replaced both my CTS and Thermostat , however whether or not the MIL is on the LC doesn't work correctly (I clear the code when it comes back) seems intermittent as I can drive a week or so before it comes back on.
Would you remove the tune for just a regular Oil change? Its not the 10.000 mile service, just made an appointment for the oil change at 6k miles.
I try not to flash as much as possible.
Note: In the future I am planning to change the oil myself with an extractor but not enough time and I plan to do a road-trip of 4k miles by the end of the year, so wanted to let them check everything prior.
I am trying to run the UM tune on my ecu, getting an error "Failed to get control unit information from the ecu"
I do not have vag-com unfortunately but I don't believe it's currently flashed. If it's already flashed, I can still just over-write the current tune because it's just software from my understanding.
I have no blown fuses, I have already checked them all!
DSG tune was supposed to set launch control for 4200, 4300 or 4500 rpm launch but the gearbox will not go above 4000 rpm? My tuner has tried 3 different files (4100, 4500, 4600) on my 2009 S3 but the actual launch control rpm is still 4000.
View 19 RepliesI have a 2002 gti with an apt software tune...
Whenever I'm on the interstate in 5th gear for a while. And I'll start to speed up. Once 4k kicks in. My boost no longer works when it normally pushes like 22psi
Then after slowing down. No matter what gear I'm in. It limits back to 10psi of boost and once I hit 4k. It goes super slowe and boost won't work
The guy told me that I should get a smoke test done (idk where or how to do that)for my vacuum lines and that I have a cylinder 4 misfire. It may be a bad coil or spark plug. But I'd like to get some performance out of my car and I don't know what else or where to start. I am new to this.
Just got stage 2 tune with tbe and bhs pendulum mount. Loving it so far but there is a loud buzzing coming from the dash area every time I hit the gas. There is more vibration in the car now that will probably stir up some rattles but this one is pretty loud!! Doesn't sound like it is in the engine compartment but more like on or in the dash by the radio or climate controls.
View 5 RepliesI've had the car for almost 5k miles, no issues. Only performance part on the car is a USP 3" catless down pipe with an O2 spacer. Car performed fine with it. Today I got an APR stage 1 93 octane tune. A few hours into the tune on my way home from work, I went to change lanes and the car hit some type of a wall with the RPMs. At around 3200 RPMs, the car felt like it went into limp mode. Did not let me pass 3200 RPMs. I got off the highway and had to keep the RPMs up because the car died at lights. Pulled into my driveway, plugged in my VCDS and there are absolutely no codes coming up. Nothing. But starting the car the car cranks and I have to give it gas for it I barely start.
View 24 RepliesI just installed a brand new 42DD downpipe in my car about two weeks back. About a week later, I started noticing a rattle that I hadn't heard before, coming from the undercarriage, about mid way back, where I assumed the downpipe is. I only hear the rattle at low RPMs, like 1000-1500 revs, when I pull away from a light. I can stop the rattle by giving it more gas before letting the clutch all the way out, but if it's something I can easily fix myself, I'd rather just do it.
I searched some DIYs and found this. [URL]..................................... I bought new sets of stage 1 dogbone mounts that I need to put in soon, probably next week when I'm on break, if that will remedy it.
Looking to put on a larger downpipe and high flow cat, 034 makes one for the Q5, but couldn't find anything for the Tiguan... would a golf r dp be the same? since its AWD like the Tiguan, I know that's reaching out there, though.
