Just wondering if I will know via a check engine light if when my Diverter valve may act up. I don't really want to add a boost gauge if I can let the onboard diagnostics do the work for me. So if I loose boost will I know?
View 8 RepliesThe CEL on my Passat came on. When I scanned it with VAG-COM, the following fault code was displayed:
000665 - Boost Pressure Regulation
P0299 - 002 - Control Range Not Reached
The car also felt like it lost its power in some way, especially when the turbo kicked in. So after some research, I found out that the Diverter Valve was causing this issue. Rubber diaphragm on original valve was made from rubber and was torn. I replaced it with upgraded valve and wow what a difference!!! Very easy to do, great write up link below.
DIY Diverter Valve Replacement for 2006 VW Passat 2.0T
I have a '07 Passat Wagon 2.0T with 80K miles. I just had the carbon scrubbed off the valves (looked like black popcorn stuck in there!) and now I'm getting a "P0327 Knock Sensor 1" light. The motor seems to run just fine (actually much better now without the carbon build-up). I'll clear the code but it will show up again the next day.
What could cause the code? Could it be related to the recent scrubbing (fully removed and replaced the valve cover in the process), perhaps a chunk of carbon floating around in the tubes somewhere? I want to go back to the guys that performed the service but I want to have a good idea of what could be the problem and the fix before I get there.
Daughters car is throwing this code of 17705 VW (1297) saying it is a "Pressure Drop Between Turbo And Throttle Valve" Car runs rough until about 2500 RPM. Replaced the pressure switch by the intercooler.
View 1 RepliesI'm set on having the European parking light feature (when the car is parked and you walk away from it). For those of you not familiar with it, by changing the Instrument Cluster coding from a 2 (USA) to either a 1 or 4 (UK or Great Britain), you can turn the car off, hit the left turn signal assuming you are parked on the right side of the street, and after getting out and locking it the 194 amber front bulb and the LED red rear ring stays on. This aids in traffic seeing your car parked on the side of the road.
Problem is that once you change the country, you get this in the ABS Module:
Address 03: ABS Brakes Labels: 3C0-614-095-C2.clb
Control Module Part Number: 3C0 614 095 S HW: 3C0 614 095 S
Component and/or Version: ESP 440 C2 H015 0004
Software Coding: 0013752
[Code] ....
What changes need to be made in this module to avoid this? The pop-up window in the coding section doesn't say anything about different countries so I'm not sure which numbers need changed.
Have 2001 suburban with the 5.3. Mechanic has replaced EGR valve 3Xs. Error code specifies "replace EGR valve". Each time car runs fine for 4-6 weeks (500-1000 miles) and then service engine light comes on. Shortly thereafter the car will not idle correctly (under 1,000 rpm) and will die at stop. I think the EGR valves are getting clogged up with carbon. Car has 130,000 miles on it.
View 4 RepliesJust read that a clogged EGR valve is common and reduced performance and increases emissions. Need to clean this valve? Where is it located?? Just noticed tonight that there is not a lot of suction from my vacuum lines and I wondered if this is related. Plus I have a p0430.
View 3 RepliesMy check engine light was going on and off, then stayed on. Took to dealer, said it was fluid control valve. Replaced at a cost of $544. (Still smarting from sticker shock.) Now, the heat does not work in my car and last night the Master Warning Light went on, as did the light for high coolant temp. warning. These flashed on then off. Hasn't happened again.
Questions: Should I be worried if the lights only flashed briefly before going away? Is it likely the replacement and lack of heat are connected?
What is the to cause to check engine light go off. I will take my car to auto zone tomorrow morning to hopefully get a code and see if I can fix it myself... if not, then I am going to have to go to the dealership.

My mechanic told me that my EGR valve was throwing a code, so I took it off and cleaned it out and tried to fish out some of the carbon in the air intake tube. I used carb cleaner on the valve and the tube and I sprayed a little bit of air duster into the tube, but it made a funny noise so I stopped after about 1 second of spraying.
When I put it back on, I forgot to snap the wiring harness back onto the top EGR solenoid. I reconnected the negative battery cable and started my car. The gauges red fine. I revved my engine a few times and everything seemed okay. Then I turned off my engine and then turned it back on to listen for any rough idling (that's why I decided to clean the EGR in the first place). Then I turned it off.
When I got out of the car, I realized I forgot to reattach the wiring harness to the EGR. I disconnected the negative battery cable and it sparked a tiny bit. I reconnected the wiring harness to the EGR. Afterwards, I noticed that it had leaked some fluid (I'm guess oil?) into my engine. There was a very small amount of light smoke or steam (not sure which), but it stopped a minute or two later. I've attached a picture for reference.
Is it safe to reconnect my negative battery cable and try restarting my car????
I have another CEL : P1404... I know what this is, EGR Valve Stuck Closed. I just have one question about this. Is the valve the pintle? If not, what is the valve?
View 14 RepliesI am getting an error code of 1201. Is this the ERG valve? How do I change out? Looking for Pictures or diagram?

(Road salt may cause issues with valve. possible fix is to replace the Front Exhaust Pipe Assembly if any shaft binding is evident.)
I have read all the posts pertaining to this code, replaced my coolant flow valve, bled all the air out of the coolant system and still am getting the cel with the 1121 code.
I have tried setting multiple coolant flow valve positions, checked all wiring in harness, coolant level is full in rad and reservoir, checked temp sensor at bottom of storage tank, checked pump operation at top of tank to attempt to clear this code to no avail.
Is there a default position the valve is to be in before cold start up?
Is there anything else that can trigger this code? What am I missing?
A couple months ago I was hearing a hissing noise under the hood throwing the same code replaced the Valve cover, after there was no issues. Yesterday saw I had CEL and I was throwing P0174 code and there is a similar vacuum leak sound coming from under the hood but the Breather in the valve cover is not sucking in air. The Oil cap comes off but the engine starts to bog, what it could be now?
View 2 RepliesI had a code for the EGR valve stuck open. I tried cleaning it but it didn't work (and didn't seem that dirty). Then I tried replacing it. Both times the code came back. What should I do now? I reset the code each time by disconnecting the battery.
View 14 RepliesI started my Subbie and all the lights just start going crazy on my dash. So I pulled of the road and started freaking out, Never had a hint of a problem. So I pulled in AutoZone and they ran the codes and now I'm being told I have to replace the brain to my transmission WTH? I don't own a DODGE!!! Had 3 different dodges and the tranny went on all. So I wont own one because of transmission problems. Now my Subaru has been parked since it can only get worse. Is this normal? All the error codes are...
P0700 Transaxle Control System (MIL Request)
P2762 Torque Converter Clutch Pressure Control Solenoid Control Circuit Range/Performance
Just got the dreaded p2440 code which is the secondary air injection valve failure. Not only do you get several lights on the dash, you also get limp mode with this code.
My GX is a 2011 with 46k, and even though several Toyota vehicles have had their warranty extended to 10yr 150k for this very system, Lexus has done no such thing.
The dealer was very familiar with this issue and knew it wasn't covered under any existing warranty. He said it's "around $2000" to fix because one of the valves is still under the intake manifold.
Even though I hate to "RIG" my GX, I ordered the bypass module from EBAY. It blocks the system off and tricks the ecu into thinking all is well.
For those not familiar, this system runs on cold starts for 30 seconds or so to warm up the cats, it has no other function.
Engine light came on a week ago, finally made it in to get the code pulled yesterday : P0441
From reading on this site, thinking its a faulty purge valve.
I have found pics of its location on an 04, but cant seem to find it on my 08 2.7L.
Got Engine Code P0022. Listed several things, Cam Position Indicator (replaced it) and CVVT Oil Control Valve Bank 2. Dealer calls them "front" and "rear". Is Bank 2 the rear (Black or gray also).
View 1 Repliesi have a 2005 Toyota Prius that the air conditioner wont work in. it has Freon in it the compressor wont kick so I did some research and my cooling fans aren't kicking on so I did a by pass test and the cooling fans motor is good they just wont kick on. I just replaced my 2 cooling fan relays and they still wont kick on. the check engine light was on in the car when I got it. it throws the code P1121 coolant valve control. I got the part just got to get it put on. Could this part stop my cooling fans from kicking on or my ac compressor from coming on.
