Engine Pinging????

icemang17 · 06-20-2008, 02:59 PM

Does your E9x M3 ping under light engine loads? I've noticed mine does on occasion, but only briefly....I suspect the gas the dealer put in was only 87 octane...since I doubt the dealer pays for premium (which is crappy 91 octance here in CA)..... I think some better gas should fix it...

Let's bring this poll back to life!!

After 15k miles and a new CAS module mine now pings.

J08M3 · 08-04-2009, 07:01 AM

I posted something about this awhile back, thinking I might have heard something that sounds like a ping too. I'm on 93 octane. I haven't noticed it recently but I have a fairly loud exhaust on now.

Did you ever have the dealer take a look @ it?

Nope, figured if my engine melted warranty would cover it. Plus I can't hear it with my new exhaust system

icemang17 · 08-04-2009, 06:56 PM

whats funny is my M3 hasn't do it since i posted this poll....of course.....runs just perfect now....

alpineweissM3 · 08-04-2009, 08:42 PM

Lucky you!

With all the new owners, let's get some more input on this.

Kyoshi71 · 09-21-2010, 09:44 AM

Your car should still not ping, even with 87 octane. Knock detection system should prevent it

I didn't even look to see how old this thread is, so sorry but my advice may help others!

The truth be said is that California gas is a low octane rating for the M3 engine. Yes, it should hypothetically run ok with 91 but with a few miles on the car (mine being a 2009 e92 M3 with 70k) I have noticed pinging under only very light loads! What works to combat this issue permanently (and has work for me) is occasionally adding 2-3 gallons of 100 Octane. I usually do this every 4 or 5 fill ups but don't think it needs it that often (just my personal preference)! In my case, Los Angeles has a bunch of stations offering 100 octane at a steep price (just google it). But not as steep as the price of doing a valve job once its pinged itself to death! Also, DONT USE FUEL CLEANERS!!!! They only work as long as its in the tank
