Idle Vibration Check Engine and Strange Exhaust noise.

[Slaughterhouse5]

started the car this morning let it warm up once I got in it to take it for a drive I noticed a vibration coming from the engine at Idle. Went to put it back in the garage. When I pushed the gas to check the Rev more vibration and strange exhaust sound.
gurgling or burbling is how I'd describe exhaust sound. felt/sounded sort of like the airflow was clogged or something.
The service engine soon light did come on.
Turned car off n restarted. Did not change symptoms n check engine was still on.

Anyone else experienced anything like this?

I'm doing my best to describe but I wouldn't really know how to do a search and I don't remember reading about these symptoms.
It's an 06 Z4 M 52k miles
I called my Indie mechanic who's German specialist he can only diagnose today not work on it so I'm waiting till next week to have it towed.

it has brand new oil and it does smell a bit strong. Molly 10-60.

Need to scan for codes.
It'll probably tell you exactly what's wrong ... usually.
Maybe you popped a coil and it's running on 5/6.

sounds like a definite misfire from bad coil

Will have it scanned for codes
any idea what a fair cost would be for repair on all coils for a Z4M?

At 51000 it seems if that's what the codes say, might as well replace em all.

it's about time for an inspection anyway

I bought mine off Amazon for $22 each.

What was the outcome? I have a "service engine soon" light on (2007 Z4 3.0si). 55,000 miles. The mechanic replaced the variable valve timing solenoid, adjusted the camshaft solenoid, and added Archoil friction modifier. The next day the light is back on. He tells me to drive it on the highway for a good while to get the oil warmed up as stop and go driving doesn't do that. So I mad a round trip of 120 miles at speeds of 55-90mph. The light remains on. HELP!

I haven't taken it to get codes read yet. I had to travel shortly after symptoms surfaced. I was going to try n squeeze in the tow or buy a reader but then I didn't have time.

Okay thanks! Not close to Wilmington are you?

Could just be time for spark plugs. Did you change them at about 65k miles?

There are two vanos solenoids, one for the intake cam and one for the exhaust cam. There is no "adjustment" for either of them. They're either on or off. They do tend to get sticky when they've accumulated a lot of miles, and need cleaning or replacement. Ask your mechanic what code(s) he's reading or you can take the car to most big box parts stores and they'll read the codes for you for free.

so I finally got to take the car to my mechanic shop. Misfire #3 cylinder was the code. got new coil, all plugs replaced. Battery recharge. Runs fine now. thank goodness it wasnt anything more serious or expensive.
