See reliability data for the BMW 3-Series. Recalls do not have to be issued only because something is prone to failure. NHTSA a government agency can only require a recall if a failure will affect safety, emissions, fuel economy, or compliance with some other regulation or law. Manufacturers can voluntarily recall cars for problems that do not affect these, though. Recalls often apply to only some cars of a specific model year, rather than all of them.

You should receive a letter from the manufacturer if your car has been recalled. You can also check with the dealer, which will know which if any recalls pertain to your car. The primary purpose of TSBs is to inform dealers about known problems with a car and how to fix them. They are not the same as recalls. As with recalls, TSBs often only apply to some cars, not the entire model year.The secondary air system is used to improve catalytic converter efficiency and reduce the emission of harmful combustion byproducts in the automotive exhaust.

For a short period after a cold start, the catalytic converter is not hot enough to efficiently combine unburned fuel with available oxygen. An electric air pump forces fresh air into the exhaust stream just before the exhaust enters the catalyst. This extra air supplies the catalyst with additional oxygen, thus speeding up the combustion of unburned pollutants and raising catalyst temperature rapidly.

At that point the secondary air system may be shut off. A check valve is usually installed in the secondary air pump duct in order to prevent back flow of hot exhaust gases into the air pump.

The secondary air system is prone to faults that illuminate the check engine light. If you have fault codes for your secondary air, check the operation of the pump. You can test the function of the secondary air components using a BMW scan tool. If you do not have access to one, you can check secondary air pump function when starting the engine.

When a cold engine is started, the secondary air pump will run for a calculated amount of time.

The check valve on the cylinder head is the most common part to fail. In this technical article, I will show you how to replace the secondary air pump and the secondary air valve. The pump has to be removed to access the valve, so the procedures will be combined. Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you are working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Do not work on your vehicle if you feel the task is beyond your ability. Vehicle models change and evolve, as they grow older, so the vehicle shown in our illustrations may vary slightly from yours.

Next question can you just replace the pump filter or is a whole unit deal? DevilsownDec 18, Post Count: 1, Likes Received Usually, the secondary air pump is siezed, which is what causes that CEL code.

P0492 - Secondary Air Injection System Insufficient Flow Bank 2

It is very common. If you do not hear a vacuum cleaner sound from it for about 2 minutes during a dead-cold start up, it is likely seized. To test it you would want to check the fuse and jump out the pump relay. If you still don't hear anything, it is bad.

You may also wish to repace the secondary air valve which bolts a pipe right above the exhaust manifold as a common diagnosis is that the valve goes bad, leaks exhaust gasses at the pump, which are corrosive, and kills the pump.

There is a solenoid that controls the vacuum to the secondary air valve that you should test as well just to be safe, but I have not seen a bad one yet. The pump is not cheap, and you cannot get the CEL to go out without fixing it sorry but you should make sure the rest of the system works properly too.

I looked at it and said "I don't need this crap" and tossed it in the trash. Not having to legally smog a car is pretty sweet. You must log in or sign up to reply here. Share This Page.

Seems like I get help with my questions I've had a "Check Engine Light Illuminated. Today is came back on. I got my trusty new code reader for the BMW and I am dealing with Codewhich is a secondary air system. My question is this Do I need to take it to the dealer or is this a DIY? As always, appreciate the help! Bill from Murrieta, Ca. You've been on the forum for a year, you should know that you must NOT go to the dealer unless you like being ripped off royally.

Absolutely agree!

I'm sure once I understand what the heck the code and secondary air system mean, I'll handle it as a DIY project. I'm hopeful it's something very simple. My car is awesome and has always been trouble free.

I do not know much about your particular code though have not researched it. This is great Alex. I appreciate the post and information. Nice job on your write up I'm off to troubleshoot further. All the best, Bill. Terms of Use. Privacy Policy. Bill from Murrieta, Ca SolidjakePM You've been on the forum for a year, you should know that you must NOT go to the dealer unless you like being ripped off royally.My wife has a i withmiles. I had a problem with the ready monitor being set for State inspection.

The code is secondary air system bank 2. My wife has been getting fuel at Mobil, which has alot of additives, at the same place for a year. When the car idles it blows smoke.

My mechanic said it was oil but it is a combination of oil and water. The car runs great and the gas mileage it ok. Tried to get it to pass inspections several times but the secondary air system wasn't ready.

I decide to take it to the local BMW dealer to see what they found.

BMW Secondary Air Injection System (Non Return Valve)

They had the car for 2 days and the problem is carbon buildup on the heads. The secondary air valves and tubes were replaced but found low air flow caused by carbon build up on the heads coming back into the system.

They said the heads need to be removed and rotor rootered. It is cheaper to just do an engine swap. I find this hard to believe that a car that drives tight and fast is destined for scrap metal. I'm also thinking of trying to get my hands on the DOS program to see if I can get the car to get rid of that code and get the inspection done.

Any other suggestions would be great. There is a company out with a product, that will put a bypass loop on the secondary air code.

This will allow you to pass emissions testing. I think if you search you will be able to find it. This is a very common problem on theses cars. Good Luck! I think it's done through INPA or???? Do you mean 10k or I went to turnermotorsports. I'm waiting for my cable to come in for Dis and the other software programs so if all I have to do is change it to Euro then I'll give that a shot. I'm also going to try and seafoam it tomorrow and hopefully I can remove some of the Carbon build up.

It was probably a waste of money since it didn't improve the air flow.
