GTI 337/20th Anniversary :: 2002 - OBDII Scanner Won't Connecting Anymore?
Apr 23, 2016
'I'm having an issue with my OBDII scanner not being able to read my ECU. I've never had issues before. I've been using a generic OBDII scanner with the Torque Android app for years but now suddenly it just doesn't connect. My biggest issue here is I have a smog check due in a few weeks. I took it to a smog check station and the guy used two different OBDII scanners with no luck. What could be the issue? Is it a blown fuse or something? If so, which fuse is it? (And no it has no aftermarket radio installed)
FYI: 2002 GTI 337

I changed my sparkplugs and coil packs last month. Was getting CEL light but it would go away after a while. I figured out that I had gapped my spark plugs way to small (almost touching) so I took them out two nights ago and regapped/ reseated them.
My car was running fine yesterday, but today when I started my car up, the engine was shaking a lot for about 10 seconds and the CEL was blinking. After 10 seconds the shaking and CEL went away...
It drove fine. I'm just wondering what could be throwing these CEL's and causing the shaking? Plugs are gapped to 0.32
Also, I had my timing belt and water pump replaced almost two weeks ago now. Any chance that could be lending to the problem?
My guess is that one or more cylinders are screwy. I'd rather not bring it into the vw mechanic since I'm tight on cash.

I got a Passat 2000 OBD-II scanner won't read for emissions testing. I did the test in 5 different place all the time when they ask to turn the key and the computer from emission test give a error and stop.
I have a radio aftermarket one of my friend have this problem and he have to install the original radio. So I buy the wire harness and the radio i install and still not able to do the emissions test.
My ABS light is flashing but my friend said this is not a problem he fix more than 4 car just replacing the aftermarket radio....

Ok I've got an 01 7.3 and the scanner I'm using won't connect to the pcm. I had it remanned and put it back on still nothing. Took the idm out and swapped it for a buddies. Still nothing. All fuses are good. Scanner communicates with every other module EXCEPT the pcm. It was shutting down on my way to my mechanics place but starting right back up. Flashing wait to start and water in fuel lights. Also would shut my overdrive off.

I recently got a 2002 gti 337 from some dude in maryland. the car had apr stage 1 and 2 installed and a euro tuned air intake...everything else was stock. I've had the car for about 2 months now and all of the sudden it started sputtering and cutting out when id get on it a little. I also noticed I was smelling a lot of gas from under my hood. i read up and found that my car had a recall on the coilpacks so I just got them replaced thinking that would work..then changed the plugs as well. i still have a misfire though only in cylinder 4 and its really taking the fun out of the car. I only have it on stage 1 because I didn't have a turboback till just recently and now I don't even want to put it on cause i have no power.

i have a 2002 automatic gti , now car was running gr8 , then poof out of the blue, car started vibrating, yeah , like am on a big vibrator, and only when its on gear D,4,3 or 2 its vibrates , if i place on P or N vibration stops.
and keep in mind it only vibrates on speeds of 10 miles ,20 miles up to ~50 miles speed , if i give it gas,the vibration stops , i slow down on the gas , and the vibration is back , and whenever i stop at a red light , car starts to present minor chocks and viberation.

A buddy of mine has a gti that is not starting. he said the temp light has been coming on and the car would start to struggle. of course he kept driving. Today it came on and stalled out. Now the car turns over but wont start. I replaced the temp sensor (green plug) and it wasn't the issue. its a 1.8t with 80k on it. 2002. I am assuming its got to be fuel or spark.

2002 GTi 337 not shifting out of 1st until is warmed up for 20 min. Then shifts fine. I've already attempted to add the "liquid gold" G-052-990-A2 ATF fluid from VW at $35qt. I put in about 200ML to no change, then another 200ML to no change. So from reading other posts in VWvortex I've seen many folks with the Jetta have had very similar symptoms. They are installing a new (Solenoid valve N92 (green) to fix this issue. Many of them are even using over the counter synthetic ATF. Before I dig in, just wanted to know what folks with the GTi 337 think about this? Am I dealing with basically the same transmission?

I have a 2002 1.8 Turbo VW GTI. Lately I've noticed that the car would hesitate slightly when slowing down. It would go up to at least 5000 RPM's or higher before it shifted over. The hesitation when slowing down and accelerating tend to happen when I drive. What to do, I went to the vw company they said if i want to change the transmission would cost me ~6k$ and f*ck me twice if if am paying 6k on a 2002 car.

I have an '02 337 GTI, Chipped but the previous owner don't know what chip is installed
Anyways, lately if I'm just cruising around the city in 5th, or on the highway, the engine will shut off completely. Electrical still on, battery light and all that jazz does not come on unless the RPMs go all the way down, then I have to actually start the car up again. Takes alot longer to crank afterwards.
Sometimes I will be driving and it happens, but I keep my foot down on the throttle, and just wait and engine will kick back in hard as hell!

ive actually owned 4 volkswagens one of which was a 2002 big turbo gti which made 325whp..... so now i have a 2005 Jetta GLI with about 41k on it. This car has a serious idle problem. Start up is fine and it runs great and hits boost perfect. It has a 6 speed, APR chip intake, forge DV, and DP. When i come to a traffic light and come to a complete stop after about 10 seconds it hiccups and the idle drops to abou 600 and then back up to normal idle. It will also do it if i just leave the car running in neutral it will randomly stutter. I have new spark plugs and new fuel injectors and i only use 93.

Ok my 2002 337 has 87,600 miles on it and for quite a while now its been making a lot of font end noise, its most noticeable at 25-30 MPH, decelerating or holding a steady speed, it disappears when your accelerating hard, and at high speeds. But the noise is horrible, its like a buffeting
Its been serviced regularly, since the noise I've done, new front brake rotors, new pads, wheel bearings, inner and outer CV boots replaced, CV joint checked. My local mechanic who's done a lot of work for me isn't sure what to think, he said try rotating the tires because it may be tire noice on the road? Im running some generic tires, the brand on the tire says "sunny" but they appear to be a good performance tire, and handle well

CEL, Triangle Displayed for the second time, Engine goes to READY, ICE starts and shuts down when I assume adequate charging is reached. However, OBD2 code thrown is P1636. Drives very well from what I can tell. But she just reported the CEL & Triangle went on again and she feels it is driving rough, like it is struggling.

I have an 2002 Volkswagen GTi 337 edition with the 1.8t engine in it. My check engine light came on so I went to my local autozone to check the code and that's what code it threw on the ODBII sensor. It says my problem could be a "failed clutch vacuum vent valve switch". It also revs about 100-200 rpms extra in between shifts and I'm not a mechanic but know a little about cars. I just don't know if I should replace the OEM clutch safety switch or what I should do about this.
