Ice formation is caused by condensation freezing at the base of the throttle body with additional collection. Thanks again I stay in Las Vegas. Some shops are reporting corrosion on the fuel pump ground that reduces power and fuel pressure. Step 2 Perform a thorough visual inspection of the engine vacuum system, and look for split, cracked, dislodged, or hardened vacuum hoses and lines. They replaced the following parts: 06F 198 088 D Repset 06D 103 469 M Cylinder head cover 06F 109 217 A Chain tensioner 06D 109 229 B Camshaft timing chain Don't know what the repset includes, but I'm guessing seals etc. The ideal fuel trim value is around 0%. In troubleshooting the P2187 code, however, this length of time can be particularly long due to the long list of potential culprits.
Spark plugs typically need to be replaced every season or 25 hours of use. Thanks for all the help guys! I didn't save any money but I will look at it as something that would have failed eventually if they were that easy to crack. The 2 hoses leading into the crankcase were cracked and letting air in causing the change in idle. Shopping for the parts and they have several youtube videos to walk you through the repair. However, intermittent faults can be extremely challenging and time consuming to find and repair, and in some cases, it might be necessary to allow the fault to worsen considerably before an accurate diagnosis and definitive repair can be made. Reading these codes does it still point to the cam follower? But has anybody found out the shops he spoke of?? I'd concentrate on this first as the other codes may be a result of the valvetronic problem. Read more: Check all the bolts holding the plenum, and anything else concerned with air intake.
Be aware though that while low fuel pressure can contribute to code P2187, this condition will almost always be indicated by a code other than P2187. I am not as the lamp has been off for a couple of days everytime I've zeroed the faults, but time will show. Sounds like you have an intake or vacuum leak. Many Thanks Hi, No I haven't got to find this elusive problem, still been told it is some sort of vacuum pipe leak or something similar. Need help with a P2187 code? Edit: And according to the dealer the cam follower is perfectly fine on my car. This type of damage is a major cause of vacuum leaks that lead to code P2187 being set.
I gave the Audi parts guy some of the fault codes, as mentioned in my previous post, and he did not recognise them. The numbers started to return to normal 0. The information contained on this site is presented for informational purposes only. And also tell them I don't want to see the car again before the problem is fixed. I don't plan on driving excessively, only to work and back. Fault codes were: P0441 Evaporating emissions control system P0171 System too lean Bank 1 P2187 System too lean at idle P0507 Idle speed control P0441 Tank breather system flow fate faulty.
I know they can't be compared vibration wise, but I still believe the Audi is a bit more rough at idle than it should be. I couldn't find the O-ring at all in mine, it's probably somewhere in the headers?? However, since there is some overlap between the symptoms of low fuel pressure and those of code P2187, it is important to eliminate or confirm low fuel pressure as a contributing factor in the presence of code P2187. The underlying cause might be fouled spark plugs, bad plug wires, a weak ignition coil, dirty injectors, a shorted or open injector, low fuel pressure, a vacuum leak, a leaky head gasket, burned exhaust valve or a camshaft with a bad lobe. When the valve sticks open, the intake continues to suck fuel vapors from the charcoal canister. The ideal fuel trim value is around 0%.
But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off. They both measured the pressure and did a visual check. I believe that these hose's will be your problem. Changes in fuel delivery will be indicated by the long-term and the short-term fuel trim values. Reduction in fuel is indicated by fuel trim values that are below 0%.
When I had a part number to research on the net, I also found out this has been thoroughly discussed on forums all over the net. Have you got a picture of the N80 valve and the hose please? Same old same old, lamp still on, dealer still has no clue what so ever. You'll see everything you need to do, as well as a side by side comparison of a good cam follower vs. If not, drive the vehicle within conditions noted in the freeze frame data or enable conditions. We disconnected both vacuum vent valves on top of the valve covers and blocked the vacuum pipes to the throttle body eventually determining bank 1 to be the cause.
You can try it out I live in Henderson. I described the part, told them where it was on the engine and the guy could not find it on his screen. Mine had the Mann + hummel rev. I can't believe I've had the car at the dealer five times ++ for this. What are the symptoms of the P2187 code? If that works, replace the valve.
We watched the additive numbers recover, reset the fault codes and then test drove the vehicle resetting the fuel trim adaptations. I just got the 6 back from the shop and HerbP you were correct in your diagnosis!! I can't believe I've had the car at the dealer five times ++ for this. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. The oxygen sensor sees a rich mixture and commands a leaner mixture to compensate. Does anyone have a diagram of the vacuum pipes and the circuit so I can find and check each one individually? The multiplicative numbers were great, both around 1. So now I'm driving around with my fingers crossed.
