Removing the black cap on the EGR valve and accessing the shaft inside? I remove it but now when I'm fitting it back it doesn't seat properly and it pushes the shaft slightly in and the car rattle like hell, what I'm missing?
View 7 RepliesSo I washed the car. All four stems had caps on them. I decide to check the pressure, a few hours after the wash. Took the stem caps off, and they all looked dry inside. The inside of the valve stems did not look wet at all. Pressed my tire gauge onto the stem out came water. From all four of them.
View 7 RepliesWe are having extremely cold weather. Yesterday my low air pressure icon came on. When I went to check the air pressure, I could not remove any of the caps.

View 1 RepliesI have a 2013 Elantra with 145,000 miles. The A/C isn't working--just blows out warm air. I checked and the compressor turns on when I hit the A/C button. I'd like to try refilling it. I can't find the low pressure valve location (only high). No luck on Google.

View 2 RepliesI just noticed what appeared to be an oil leak around the valve cover gasket, which the VW dealer has determined to be a defective cam sensor. Apparently the VW parts distribution center in Wisconsin has 530 of these in stock, so it may be a common failure. This is on a 2010 GTI with 28,xxx miles. Thought the community would like to know.

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.
The annoying buzzing from the brake booster check valve that comes from the left of the instrument panel when lighly braking (especially when parked or waiting at a traffic light) is a well-known problem, as it was the subject of a Lexus (and Toyota) TSB for 2004-2010 models(see link below to the clublexus link), and has been discussed on many forums for Lexus and other cars.
I just bought a new 2012 RX 350 last month, and within a week it started making this buzzing noise (left instrument panel upon light braking). I took the car to the dealer and without listening they said that they knew it was the brake booster valve (the noise is the rattling of a ball bearing when the valve is malfunctioning). They replaced the valve and the noise went away (the loaner RX they gave me made the noise even worse).
Well, 3 weeks later, the noise has returned!
2012 Elantra GLS. Wife comes home and says the TPMS (tire pressure monitoring system) light on the dash is lit. I check the tire pressure. None abnormally low but I decide to top them off. Notice that two of the valve stem caps are broken. The tips are broken off so I can see the little red gasket. On opposite sides of the car. No damage to the wheel covers. The valve stems don't stick out past the wheel covers so I wonder how the caps could have gotten broken. Could that be why the TPS system is giving me a warning? If by chance there was a pressure issue does the light reset itself or does the dealer have to do it?

View 2 RepliesI am about to change the spark plugs on my 2007 Prius with around 120,000 miles on it. While I am doing that I wanted to possibly change the PCV Vavle. Where is it located? Also does my Prius have a fuel filter? I would change it also if it does.
View 2 RepliesI had the PCV valve replaced around 60K, then at the next service they wanted to do it again (not reading the records that they had already done it). Then at 80K they wanted to do it again, I declined. Today it was in for 85K service and they said "the PCV valve is dirty and needs to be replaced." The advisor told me after the initial replacement at 60K the interval is 20-25K miles.
View 10 RepliesWhen I did the PCV valve on my wife's car it looked like nothing more than a metal housing with a ball bearing rattling around inside. That left me wondering, why not just clean and reinstall the original valve? Is there a reason why that wouldn't be nearly as good? I realize it's a $10 part but I have to ask the question before I go buy another for my own car.
View 2 RepliesI have a 2004 toyota Prius with 185k miles on it and recently got the CEL for P1121. I checked both coolants and turns out that the engine coolant was completely out. I immediately filled it up and the CEL went off for a couple days. It has come back and is on constantly, I checked the coolant and the coolant is at the correct level.
View 19 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?
how easy is it to replace the Valve Stem Core of a tire? I got a hunch one of my Gen 3 Prius' valve stem core pin is slightly depressed and might be leaking air.
Is it expensive and do I need to worry about the TPM or is that a separate component?
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.
View 19 RepliesI had my a/c recharged in April and it was blowing hot again by July. I brought it back in today and they told me that it is leaking out of the Schrader valve on the low pressure side. They told me that they would have to replace the entire line which would cost a few hundred just in parts. Why can't they just replace the valve. The tried calling auto stores for a special part, but could not find one. How to seal or repair just the leaking Schrader valve and not the entire line?
View 8 Replies2004 Prius, 98K miles ... I recently replaced the coolant control valve (received code P1121) and added coolant. Trouble codes were cleared. I am now getting the red triangle intermittently. When I drive the car, after a few minutes, the red triangle comes on. I can shut off the car, and turn it back on, and the red triangle comes back after a few minutes. The car seems to drive normally.
