Golf/GTI VII :: EPC Light Came On - No Fault Shown On OBDII Reader
Sep 22, 2015
My 2015 GTI SE PP 6-speed is 7 months old with only 4000 miles on it. I took her out for a drive on twisting, changing-elevation roads near my house this past Sunday when it was 100 degrees out. My AC was blowing full-force and I was driving moderately hard up a twisty hill at 35 miles an hour in 2nd gear when the EPC light came on and the power was cut noticeably, as it went into limp mode. I pulled over, shut her down and restarted. The EPC light went away, the power came back and I have had no further issues. I only have an OBD II reader, not VAGCOM, and the OBD II didn't read any fault at all.
How concerned should I be about this episode and secondly, what can I look for in case there's a reasonably simple physical issue (like a leaking hose or loose sensor plug) that I can rectify instead of taking it to the dealer (it is under warranty, but my closest dealer does not engender confidence- they treat you like you're a problem when you walk in the door)?
This is my first car with tons of electronics and I'm a little concerned that the EPC issue could get ahead of me. I'm a good wrench, but this is something the ECU is dealing with and I'm not very clear on how to proceed.

My dvd reader (optical) go out in their MFD2. I first noticed something was wrong when i didn't see my compass working. Then it would go on and off for a bit and now the nav disc is not recognized at all. Even better yet, I can't eject the disc....

Replaced my Crankshaft position sensor and cleared my codes but I'm still getting a P0016 and P0018 error. Car runs fine at the moment. Can't smog and therefore register it till I figure it out. Next step is replacing the Camshaft position sensor.

2000 Jetta MKIV ... 2.0L GL
I've been dealing with random misfire codes on my Jetta (P0300, P0301-P0304). I've since replaced the spark plugs, wires, fuel filter, MAF senor, & camshaft positioning sensor but the problem still persists. The misfires occur right on start-up and don't stop which is leading me to the coil pack being bad.

1st: 00532 Supply Voltage Too Low - Intermittent
2nd: 00592 Seat Belt Switch on Passenger Side -E25
Resistance Too High - Intermittent
3rd: 00592 Seat Belt Switch on Passenger Side -E25
Resistance Too Low -Intermittent
the piece where the passenger side seat belt clicks into has a chunk broken off of it, now im assuming that this is causing most (maybe all?) of the problem here?

My wife was driving her truck yesterday and said the MIL light started to flash and the truck felt like "it was about to blow up" . So when I got home I busted out the trusty old scanner and this is what I got:
P0305- Cyl 5 misfire'
P0354- Ignition coil D primary/ Secondary circuit malfunction
P0304- Cylinder 4 misfire
The truck is a 2005 5.4 with ~130,000 on it and it runs very well for the most part. I have done the spark plugs before the summer and replaced them with the motorcrasft sp-515s. I am guessing the problem will be with the #4&5 coil packs. is there a way to troubleshoot these?

I have a couple of fun curves I hit daily and most days I push the car pretty hard. So, I hit one the other day on the way home from work and the freaking airbag light came on with a fault message. I immediately suspected that when my seat belt tightened that the sensor in the seat belt connector freaked out. I later scanned with VAGCOM and confirmed that I have the famous high resistance message for the driver side seat belt connector. I remember that some people had luck by cleaning the connections to the bottom of the seat and the switch. Maybe that is all I have to do. Got to love the .:R. I break stuff as fast as I fix stuff.

So I unplugged my front seats and the airbag fault light came on. When I hooked them back up the light remained on. Is there a trick to this that I am unaware of? I would really like to get this light off my dash asap.

Looking for info about taking the info/control screen apart. I have a very small amount of moisture that only shows under certain light conditions.

I recently bought my new (For me) R32, the first owner of the car remove the 2 catalyst from the car and now I have the check engine light on. When my friend put the vagcom on the car it shows an oxygen sensor fault. What can I do to fix this? can I just buy a MagnaFlow exhaust?

I have an APR stage 2+ R with 70k miles and have been getting strange CELs recently. What is going on. Here is what happens:
1st- a ding a ECS fault displays in mfd.
2nd- a ding and ABS fault lights up
3rd- airbag light and tire pressure lights illuminate
4th- steering wheel light illuminates.
5th- all lights disappear after a few minutes, except the airbag light.
Car drives fine and lights do not illuminate upon restart. The light show appears randomly usually a day or two later.

The vehicle is a 2004 Jetta MK4 1.8t.
Last thing I had replaced about 2 months ago was the Solenoid valve, the MAF and Solenoid hose. Car ran fine for about a month, and bam...engine light came back on, along with the ASR light. At first it was saying "cat converter" so I researched that, and what a surprise, it spoke about being a $1k piece to replace. NOTHING HAS BEEN CHEAP ON THIS CAR, and I'm losing my mind.
The latest adventure happened today coming back from the gym. Car started jerking (which has been normal since every now and then the ASR light will come on, which I'm told is the traction control light. Causing the car to jerk. Simple fix is pulling over, shutting the car off, and turning it back on. That always clears it, and then I'm back on the road.) but instantly it lost power. It wont shift, but the traction control light didn't come on. I plugged my OBD2 tool up, and came back with these fault codes:
P0420: Catalyst System Efficiency Below Threshold (Bank 1)
P0753: Shift Solenoid "A" Electrical
P2637: Torque Management Feedback Signal A
I'm going to go to these guys tomorrow, but I would just like to get an educated guess on what might be going on, so I don't look like a lost dog while they're figuring out what to do next. These guys seem knowledgeable, but they're missing something since I've been in and out of their shop several times and still getting my traction control light on at random times, and now all 3 of these codes.
Does that Solenoid code have anything to do with the Solenoid valve they put in? I was told that cleaning the throttle body and the cat converter might work. Would those be cheaper options to consider, and see if that works?
I also read that unplugging the alternator and plugging it back in, then cleaning the male and female with electrical cleaner might work. I was told about a month ago that my battery barely passed. Could this be causing any of my issues? I also did a log while I was driving, but all that's showing up is a google map document.

After running to operating temp, if the car is turned off then restarted (like you would at a gas station, which is where I notice this) the engine will turn and turn and turn but not fire. I have noticed that stomping on the acceleration will cough it into life during this procedure. This doesn't happen every time and I have recently run high octane gas during a long distance trip.
106K miles...
Recent p0441 fault codes and gas cap warning light...
No other problems or codes...

Having issues with the rear tailgate door unlocking. Seems like mine on occasion is only making a noise but not unlocking completely and showing the door ajar light with the beep. When it happens, its a pain to get it to stop and close completely, or even open. I have to push hard on the door to get it to stop.

So I was cleaning the house and found a OBDII I was wondering how I can use it. Would the car still give me codes even if there is no check engine light?

Me and the wife got in the ole '97 1.8. After may be 5 mins or so, I noticed the CEL was on.
I've only ever seen the CEL light on once, and it was b/c the gas cap was loose.
The car ran fine, nothing out of the ordinary. After getting home, I plugged in the dusty OBD reader thingy and it spit out a code, I can't remember. P401 or something like that. EGR emission low?
It appeared that my EGR valve is all cruddy with carbon deposits. So Is removal/cleaning terribly difficult? I'm thinking some carb cleaner and maybe a scraper would do the trick.
