Golf IV / Jetta IV :: Code P0785 - Car Sometimes Not Shift From 3rd To 4th Gear

When I'm driving, the Jetta will sometimes not shift from 3rd to 4th gear, so I just turn of the car a start it and it seems to work, but eventually does it again. Once it is in 3rd gear it does not downshift and stays in 3rd even when stopped. The trouble code is P0785 which is the shift/timing solenoid. Not sure if I need to get a new part or which solenoid to get. Also I cannot figure out where this solenoid is actually located or what it looks like.

Golf IV / Jetta IV :: Cylinder 2 And 3 Misfire - Code P0411

Alright so my car is popping up 4 codes.

P0411 - Secondary Air Injection System Incorrect Flow Detected

P0300 - Random/Multiple Cylinder Misfire Detected

P0302 - Cylinder 2 Misfire Detected

P0303 - Cylinder 3 Misfire Detected

Vehicle: 1999.5 VW Jetta MK4 2.0L GLS (AEG)

The P0411 code I have had for a while now and I been lacking to fix it. I pretty sure I can get this fixed but it doesn't cause problems so I haven't paid to much attention to it. Anyways, the other day I noticed a puddle of coolant under my car so after checking it out, the water pump was leaking so I bought a new one and replaced the old one. However, during the replacement process I had to remove the timing belt and I accidentally turned the top pulley about 1 notch and didn't notice at the time. After putting everything back on, I turned my car on and the engine sound a bit weak so I ran for about 10 minutes around a couple blocks.

I instantly noticed that the car had no power and it took me a long time to speed up. When I got back, I plugged in my scanner and I only had the same P0411 code and nothing else. After carefully reviewing the camera I had recording during the water pump replacement, I notice I had turned the top pulley a bit so I went ahead and removed the timing belt, readjusted it, and it worked! I was excited that the car was working fine again. Soon after, I headed out to take a drive and noticed after 60MPH the car didn't have much power. The car still accelerates after 60MPH, but extremely slow. As soon as I arrived back home, I plugged in my scanner and that is where I seen the 4 codes. Now my question is what could have caused this? Could I have damaged something when I ran my car with the incorrect timing?

Things I have done so far:

-I checked to see if I left anything unplugged.
-I checked for any vacuum leaks
-I checked my oxygen sensors so see if I was running rich/lean

Things I will do after work today:

-Check the spark plugs
-Check spark plug cable for damage

Golf IV / Jetta IV :: Error Code P0411 Causing The Car To No Start

I have a 2005 Jetta 1.8t and the thing will not start! The battery is fine, and has been recharged 100%. The fuel pump is pumping. It cranks all day, but just won't start. The only error code i'm getting is a P0411 which I understand is a leak in the vacuum system somewhere.

Golf IV / Jetta IV :: Check Engine Light Came On - Code P0411

Just installed a short Ram intake on my 2000 Vw Jetta 1.8t. Had the Intake for about 250 miles and now the check engine light came on. Just pulled the code p0411 secondary air injection system incorrect flow detected. Is this just cause there is more air going through the MAF sensor?

Golf IV / Jetta IV :: Error Code P0411 - Car Won't Triggers Quickly After A Reset

Whenever P0411 triggers for me, it is very late into driving (i.e. like 30 minutes into the freeway type of situation) where the engine has already hit optimal temperature. I've gone 1000 miles after reset before it triggers. Sometimes 200 or so miles, but it never triggers quickly after a reset. I'm unsure if it matters, but the VR6 does have a cold air intake (and I do have the breather hose connected & maf correctly connected). I'm pointing it out because p0411 became an issue about 500 miles after I had installed the cold air intake.

Golf IV / Jetta IV :: 2003 1.8 Turbo Throwing P0411 - Secondary Air Injection System Error

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.

Golf IV / Jetta IV :: 2004 - P0411 Code / Secondary Air Injection System Incorrect Flow

2004 VR6 24v ... I had another thread about my son's car stalling after driving about 20 miles and then running good again after letting it sit for a couple of hours. Anyway I changed the Crank Position Sensor and I have been driving it work and back the last couple of days so I am starting to relax that the CPS fixed that problem. Won't be positively sure for a while as the problem took a while to occur. So far so good.

While coming to work today the car picked up the P0411 code, secondary air injection system incorrect flow. When I changed the CPS sensor i unbolted a module underneath the car by the oil filter to get better access to the CPS. I did not remove it, just unbolted it so I could push it out of the way about and inch.

After putting it all back together and driving it for several trips with no stalling this P0411 comes on. Is that module I moved the Secondary Air Pump and could I have disturbed something. I will check it when I get home. How critical is that code. I read where it works to warm a cold engine. What effect would there be driving with that code?

Ford - Explorer :: 1999 - Codes P1151 And P0133 / Shutter When Going Up Hills

I have a 1999 explorer with a 4.0 ohv auto with about 174,000 miles on it. the PO changed the coil pack, wires, plugs, MAF and cat on it trying to get rid of codes. I know the from searching that they are both precat 02 codes. So I am planning on looking for vacuum leaks with propane around intake and egr and checking on the fuel pressure and wiring and connections. Is there any thing else I should check out? for both sensors to throw this code? The truck runs ok just has a shutter when going up hills and stuff.

Ford F-150 - 1997-2003 :: Multiple Exhaust Manifold Studs Broken On Both Side / Codes P1131 And P1151

I have a 2000 with a 5.4 and 166K miles. It had multiple exhaust manifold studs broken on both sides. Now that thay is fixed, I am getting the p1131 and p1151 codes. The EGR tube was also replaced at the time of the manifold fix. I checked over all the tubes and electrical connectors to rule out something simple but did not find anything out of place. The intake manifold was replaced with a new Napa one less than 5K miles ago as well.

Could the leaky exhaust manifolds over time set the fuel trim level high and now that they are fixed, the ECM is thinking it is running too rich? Can the ECM be reset to zero? There is also a ticking/rattling noise when you accelerate that seems to be coming from the fuel injectors. I listened with the stethescope and they are the only things that sound like the noise I hear. Could these all be related?

Golf IV / Jetta IV :: 2000 GLS VR6 12v Codes Won't Go Away

Okay I have a 2000 Jetta GLS VR6. I had the engine replaced after i found out the block was cracked when replacing the heater core. ever since it was replaced the car runs great but it keeps throwing these 4 codes.

Golf IV / Jetta IV :: 2001 1.8t - Two Different Engine Codes

I have a 2001 1.8t beetle and doing some research to buy parts I came across two different engine codes. My trunk says I have a AWV engine but the cylinder head says AWM. This is really confusing as looking them up I get three entirely different options for this car.

Golf IV / Jetta IV :: 04 - Idling Pitfall With Codes

My gf's 04 gti 1.8t 5spd is having idling issues. Here's the rundown, at idle it sits at 800 rpm but when given a rev it then becomes erratic and fluctuates between 500-1100 rpm. When throttled again lightly it returns to normal 800 rpm idle. The car will try to stall a little bit. Now for the codes and lights. The lights are the traction control light and the check engine light. The codes are p0102 (MAF) and p2181 (coolant system performance). I have recently had a misfire which I took care of with 4 new coil packs. I kept the 3 good ones I took out. I have to change the plugs still but don't think it's an issue. Has new clutch and sits at 148,852 miles.

Golf IV / Jetta IV :: 1.8t Won't Start / Throwing 2 Codes

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.

Golf IV / Jetta IV :: 2.0 Throwing Multiple Codes

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.

Golf IV / Jetta IV :: 2000 - Got Transmission Codes?

i have a 2000 jetta 2.0 i am in desperate need of a new transmission. Ever since I bought the car I rarely had third gear and today on my way from southeastern PA to northwest Ohio seem to pretty much completely lost first unless I really slam it in and fifth likes to disengage every now and then unless I hold the shifter in place both first and fifth were slowly giving me problems until it got really bad after todays 8 hour drive. My transmission code is EBP, is there any other codes I can put in my car from another 2.0 or do I have to get another EBP?
