Golf IV / Jetta IV :: 1.8t Won't Start / Throwing 2 Codes
Jul 18, 2015
Throwing 2 codes -
P0172: too rich
P1176: post cat 02 reached limit
Last time it turned on it had horrible air flow, it felt as though it was choking. definitely not a misfire. occasionally after spirited driving the engine would die after I came to a complete stop then worsened to cutting off when I put the clutch in at high rpms. also have a slight loss of power. I also recently added a 3" tbe and changed coil packs.

I recently had an issue with a coolant leak. the Y shaped coolant line connection went bad located under the power steering reservoir. The car got hot and the coolant light came on i immediately turned the car off and saw coolant leaking out from this.
Now today I start my car it has a rough idle and dies once it dies it doesn't start again and the epic light comes on throwing the codes
17579 P1171 Throttle Actuation Potentiometer Sign.2 Range/Performance
17951 P1543 Throttle Actuation Potentiometer Signal too Low
16497 P0113 Intake Air Temp.Circ High Input
17987 P1579 Idle Speed Contr.Throttle Pos. Adaptation not started

So my car has been dropping multiple codes after I scanned her and found all five: p0303, p1128, p0172, p1300, p0301. She is just a simple five speed AEG and has no mods other than a SRI. I already replaced the MAF but that ended up causing more codes and I have checked the vacuum lines to no avail.

So recently I took my engine apart to do a valve cover gasket and Ecs tuning 2.0 coil conversion. I noticed a good amount of oil in the plug tubes so I got out my trusty soap dispenser and started pumping out oil. Pulled plugs and cleaned them (wanted to make sure oil was all out b4 getting new) also while I had it apart I wanted to take intake off, ( just to polish it and clean out any carbon inside).. Well I never ended up doing that. I removed the injector connections and realized it was to much work for such little satisfaction. So I plugged the injectors back in.
I got my car all back together and now I'm throwing 6 cel codes!! P0102 (maf) which I'm assuming b.c I took it off for so long, p0201, p0202 ( injector 1 and 2 miss), then some misfire codes p0300 (random) p0301 (cylinder 1) and p0304 (cylinder 4). The car starts runs very rough then cel comes on and blinks. I was thinking maybe the oil getting down to the combustion chamber couldn't be the best for it but it would just burn off. Only other thing I did was take off the thottle body and cleaned it.

The car doesn't seem to run that rough.
Replaced coil pack and spark plug wires with parts from O'reilly auto
16684 - Random/multiple cylinder misfire detected
P0300 - 35 -10 - Intermittent
16686 - Cylinder 2
P0302 - 35 - 10 - misfire detected - intermittent
16687 - Cylinder 3
P0303 - 35 - 10 - misfire detected - intermittent
I have searched and browsed multiple websites and threads to no avail. They all seem to be dead ends.

So my girlfriends's 2001 2.0 Golf (engine code AVH, 153k miles) began throwing codes for misfire on cylinder 4 and for the o2 sensor (post-cat) recently. I went ahead and replaced the spark plugs, wireset, and the coil pack. They were way overdue. The CEL went away for like 30 miles, and then came back. Now it's reading misfire on cylinder 3 and the same thing for the o2 sensor. What else it could be? Search is coming up blank, most people replaced the coil pack and the CEL went away.

I just has a gen 2 haldex and wireless controller installed. 10 minutes of driving around getting on it in sport mode, I feel a thunk from the back and when slowing down a few odd shudders. Drove it cautiously a bit more and felt fine, then harder and harder. Felt better, no understeer, seemed ok.
Got home and scanned with Vagcom, got the errors below, cleared DTC and scanned again, same errors.

Any LED I can throw in the footwells / license plate area that won't throw a code? I'm using the ones from superbrightleds.
They worked everywhere except the license plate and the footwells. Everytime I get in my car I have to see (check license plate lights!) and a bulb out icon.

My 08 2.4l sonata gls won't start. I started it this morning to warm it up while I cleared off all the snow, it was running for about ten minutes. I turned it off and about twenty minute later went to start it and it will not catch. All the electronics are running and the engine turns over but it won't start. I replaced the battery in December, the oil was changed last week as well as the air filter. It has 93k miles on it. What could be the problem? I did go borrow a diagnostic scanner and it is throwing a P2110 P2118 and P2119 code.

Yesterday I purchased an 04 Jetta 2.0 with 179k. It was super cheap and pretty clean. Needs work but I bought it to fix it and daily it. Anyway. When I initially went to look at the car, It started right up. after test driving it, I turned it off to make a deal with the guy. Then started it back up to pull on the trailer. Towed it home, Started right up again to get off the trailer. All was good.
This morning I go out, scan the codes (with an obdII scanner, not vag-com), get the codes, then erase them. Just to get a fresh start at the issues. I go to start the car, and it wont start. Turns over but doesn't fire. Could erasing the codes have done something?
Here's the codes that popped up in case they're important to this situation. P0043, P0102, P3081, P0113. I did scan the codes again after I erased them and it wouldn't start. P0043 is still there.

I was driving down the road when my car (02 GTI 12v VR6) suddenly died. I pulled off and tried to restart it. It sounded weird, kind of metallic like maybe the clutch went out. It seemed to be firing, but would not turn over so I stopped trying for fear of damaging something. I thought the timing chain may have come loose, however I didn't hear anything catastrophic like valves breaking so if that's the case then hopefully it only jumped a tooth or two. I scanned it and a bunch of codes came back. I did have the battery out for a while before scanning so I'm not sure if some of the Central Convenience codes are due to that or not.
Here's the full scan:
VAG-COM Version: Release 409.1-S
Chassis Type: 1J - VW G/J/B Mk4
Scan: 01,02,03,08,16,15,17,19,22,35,46,56

I have been driving my car with a known P0016 and P0018 codes for quite a while. I know, I know.... Car was not worth sinking a lot of money into so we decided to run it till it died. It has run great for about a year but now it finally has problems. Day before it ran great. First thing in the morning it tried to start and then stalled. It will try and start and putt, putt two or three times and die. I think it has jumped timing. Before I trash it I would like to make sure that is the problem. My question is, can I check for a jumped timing chain at home without doing a major disassembly? I don't have access to a VAGCOM. If that is what happened I will get rid of it and move on but I would like to verify that is really what happened. There is no valve clatter so I don't think it jumped enough to damage the heads.

I own a 2003 VW Jetta GLS 2.0L 4 Cylinder and my CEL recently came on throwing the PO420 code (Catalyst System Efficiency Below Threshold (Bank 1)). So I replaced both the upstream and downstream O2 sensors. Well just one day after replacing the sensors the CEL came back on with the same code. I was wondering weather or not I should replace the whole catalytic converter or if there was anything else I should try. The car runs fine, exactly how it did when I bought it.

I have a 03 GLI 24v VR6 thats throwing a P0113 code, which is for the intake air temperature sensor. The sensor is part of the MAF sensor, ive tried 2 brand new BOSCH MAF sensors yet the same check engine continues to reoccur. Is there anything else that oculd be triggering it to come on? Is there anyway to bypass/disable it through vagcom?

I'm working on a 2003 Jetta GLI 1.8t (MT and 140,000m if it matters). The CEL has been on for a couple of weeks because of an exhaust leak throwing a catalyst efficiency code. After I make this post I'm going to run down to the advance auto I used to work at & see if I can borrow the scanner to see if there's anything new, but as of right now I don't know. I'll update the thread if I find anything.
The car started yesterday AM perfectly fine. Started again when I left work around noon. No problems with the start, idle, acceleration.. it's all good.
3 hours later I tried to start it to go pick up my kid from school but it just cranked without firing and would not start. I took care of business with the kiddo and then started trying to pin down the problem.
1. Opened the door & listened for the fuel pump to prime.. No sound.
2. Noticed the dome light is on.
3. Checked ALL of the fuses on the side of the dash.. All are fine. Turned key to listen for secondary prime.. no sound.
4. Bought Fuel pump relay & replaced.. no change.
5. Cursed.. a lot
6. Bought fuel pump.. replaced.. no change.
7. Cursed a lot more.. and cried a little too.
8. Noticed the fuel pump was now priming with the key being turned, but still not when I open the door.. Dash indicates the known CEL, but now I notice that the EPC light is on too (this could be from all the fruitless cranking drawing down the battery charge)
9. Figured I'd throw in a new crank angle sensor cuz of the EPC.. no change.
10. Shot starting fluid down the intake.. didn't hit a lick.
I feel like I'm at a dead end.. It's acting like a bad ignition control module, but there's no such thing on a vw 1.8t.

I have a 2008 MK4 2.0 with only 53,000kms. At 40,000Kms I put new OEM spark plugs.
Just recently, every morning when I start the engine is sputtering and rough running. The engines want to die but I give a little gas, and run rough like it is only firing on two or three cylinders.
When it gets to the normal operating coolant temperature it runs without any problem and I can use the AC. Its only give me this problem on the first start of the day.
Does not have any MIL light on the instrument panel. I scan it with VCDS-Lite and do not found any fault codes. The only thing that's come to my mind is to change the Green Coolant Sensor.

I keep throwing a P0411 - Secondary Air Injection System error. My previous pump was seized so I replaced it, and broke a few of the chintzy air hoses in the process. Now, with new pump installed and new air hoses connected, I can go about 5 days before the code comes back on.
So to recap, I have:
Replaced the air pump
Verified the new air pump functions, yepReplaced the air hoses
Verified connection of air hoses at all junctions
Checked the Secondary Air Relay for function
I have not yet checked the solenoid - unsure how to do so.

My girlfriend has a 2000 B5 and it's been throwing a p1136 (Fuel trim too lean: probably a vacuum leak) and p1113 (B1, S1, pre-cat O2 sensor) for about two weeks now. How long can she feasibly leave this stuff before doing any real damage?
I just don't have time to check her manifold for vacuum leaks for at least a few months (summer) or deal with the O2 sensor. I mean she doesn't need to get it inspected until Nov 2007, so, all she has to put up with is that really annoying beeping and "emissions workshop" lightshow every time she starts her car up.

I have had a wet weather issue twice, once last fall and once this spring. Both times were very wet and damp conditions causing a sputtering and chugging and dying at lights, both times no codes and after drying out in brother's shop it went away. Now this weekend up at the cabin it reappeared, again very wet conditions. Replaced the MAF...no change. Sputtered and chugged my way home with it killing at most stop signs/lights. Finally got home and couldn't even back the TT up the driveway, it would kill. Finally threw numerous codes (misfire in cylinders 1 and 9, and misfire in first 1000 revolutions). I'm thinking COPs as the plugs are not that old and the little research I have had time to do suggests this also. If it is COPs, I have heard there are some to avoid and some that are recommended?

The car is a 1994 volvo 960, it has a rough idle, and its idling high (1500 rpm and higher) its throwing 7 codes, we just replaced the O2 sensor, we reset the computer, and still have issues, (though its no longer running rich!!!)
Here are the codes
1-1-3 injector group 1
1-1-5 injector group 2
2-1-2 O2 signal
2-3-2 long term fuel trip idle
2-1-4 rpm signal
3-1-4 cmp signal
2-3-3 long term ilde air trim
We also checked the idle control valve points 1-2 read 15 ohms and specs say 10-14, for the harness side port 1 read battery voltage (12.3) and port 2 initially read 10.2 then we wiggled and played with the injector wiring harness and it read 11.8.
We also poured fuel system cleaner right into the fuel filter and started it up, and just dumped the rest in the tank
I'm heading out to check those other sensors but what else could be causing these issues, also the temp gauge is reading cold all the time, but the fan kicks on when the car gets warm.
