What could this be?

Shaz · 06-09-2010, 10:27 PM

Hi everyone again,

So this have happened to me before...last time it was the ignition coil...So I was driving on the Hwy put my car in sports mode and floored didn't really feel the boost but what I got was an engine service soon light with power reduced on my iDrive screen, stayed there for maybe 30 seconds and then all gone all of a sudden.

Should I be worried?

1. take tune out (if you have one)

2. take it to the dealer it seems you have a HPFP (high pressure fuel pump) failure.

mine comes on and stays on tell i turn the car off and then when i restart it its off , it doesn't crank hard so i don't think its the fuel pump, it seems to do it more if i run the ac at all
any ideas

Nope no the tune, Its could be an array of things

1. leaking boost somewhere and your getting a limp modes when you hit a cartain psi witch seems like top end.

2. You could be misfiring, Its seems like you might have a bad coil/s injector/s because my car misfires and limps ( not when iam driving though only when i first start the car in the morning) due to a bad injector. You might have the same problem except a bit worst.

Check your electrics, in this case I'd check the battery since the generator is probably still ok.
Started a thread about this a while ago, although I haven't bought a new battery since they didn't have any lightweight ones at home, I recharged the old one and all my problems dissapeared.

Low battery charge gave me all sorts of funny codes and limps.
Mainly throttle position sensor, dsc, tpms and abs.

If you only get it while stomping the throttle it might not be the issue though. I only got it while cruising, driving a bit more aggresive I never got any codes.

It happens every time I step hard on the gas. It happened again today.

If you are getting a WOT CEL with reduced power, but the CEL goes away after re-start, then it could be your fuel pump.

Usually with a fuel pressure drop you will feel the car stumble upon sudden WOT just before the CEL, but not necessarily. Do you have access to a BT cable? Check codes before going to the dealer!

The light goes off after I slow down to like 2k RPM....Car does not stumble or shake.

vasillalov · 06-11-2010, 12:35 PM

Why not take it to a dealer?

dmurray14 · 06-11-2010, 12:42 PM

I had that happen once with a VANOS code...hasn't happened again though.

what was the solution?

It might be leaking boost.

Nothing, it just happened once so I didn't worry about it

Shaz · 06-11-2010, 08:43 PM

I feel like the car is not at its full potential power wise.

wesborl898 · 06-12-2010, 09:42 PM

i had this symptom with vanos...replaced by dealer

bulldog_yyc · 06-13-2010, 08:36 AM

you need to get a BT cable and read the codes, otherwise its a guessing game. If it is indeed a boost leak, 30FE code I think, you don't need to go to a dealer; any competent shop that has worked on FI cars should be able to do a smoke test and find the source of the leak.
