need some repair:) more likely spark plugs or coil,but in cause you would feel the engine work differently, may be O2 sensor. hook it up to computer and read error codes u can do it at autozone for free if do not have your own

Yup, Autozone can read the code and tell you what the problem is, or at least get close. It could be as simple as a loose gas cap.

Hi Mr.BMW745li,
Were you able to find out what the problem was and how to fix? My 2006 750li just has this same check engine message, looking for help. Don't really want to bring to the dealer.

Thanks.

Hi pmpn8ez,

Got my 2006 750LI to AutoZone today for scan, the code is P1434, and have the printed out message:
Troubleshooting P1434
OEM Band: Volkswagen

Definition: Secondary air injection relay circuit short to positive
Explanation: Open or short circuit condition
Probable cause: failed air pump relay

First, is this possible that this code is not accurate, the scanner was for Volkswagen only, did not work for BMW?

Second: I see a few post on this forum for this code P1434, and a few members saying that the problem was bad gas cap, but the code did not say anything about gas cap. Anyone esolved this problem code by replaced the gas cap?

Thanks,

Does'nt hurt to replace the gas cap first, it's the least expensive part. sometimes the rubber gasket around the cap tends to wear off and show sign of cracks which allows the fumes to escape. Check for these cracks.

My engine light turned on awhile back & all I did was remove & then put back on the gas cap & made sure it was on tight (mine clicks) & the engine light went off after a half day of normal driving. gl

I checked my gas cap, looks good, and closed tight. Put it back carefully and waited a few days, but the code was not cleared. I will look for a new cap.

I also bought a OBDII bluetooth interface ELM327 from Amazon for $23 and use free Torque app for my Andoid phone to read the code. I do see code P1434 as what AutoZone got, but tried to reset, it did not clear. I was able to clear O2 sensor check engine on my Honda Odyssey, may be it just does not work on BMW.

May check engine light disappeared now, so it looks like the new gas cap works. just take too long to clear the code?

Just had the same fault pop up yesterday. My car is running great, so I'll take it by my indy to see whats up.

Mine ended up being thermostat fault. I replaced mine about 10k miles ago, so we just reset computer and I'll give a few days to see if it sticks again. I lucked out so far...
