Help! 2003 c230 kompressor ESP idle rev surging
Hey there, had a headache-inducing experience: started my c230, for the first time the ESP malfunction light came on, telling me to take it to shop. At idle, it was surging up and down, up and down, like I was revving it (I wasn't). When I did press the gas pedal it was responsive like normal, however when I pressed the brake, brake felt stiff. I didn't actually drive it, I just backed out of the driveway, stopped, then pulled straight back in. It was difficult to come to stop, stiff brake issue. I turned it off, restarted a few times, problem persisted. Finally I let it sit a couple hours, then restarted it and the problem was gone, no ESP malfunction. I haven't had it since, but I expect it again. The check engine light remained on for a bit, it's not on now, but I was able to pull the following codes:
P0300
P0130
P0150
P0304
P0155
P0135
P1747
I doubt any of those things is the cause of the problem, it is too odd that 7 codes would all throw at the same time, and then all clear at the same time once the problem went away. Any experience with this, any ideas? Greatly appreciated.

Stiff brake means something is wrong with the brake booster. A vacuum leak from the unit would make it essentially inoperative, while also making the engine run rough. It's weird that the symptoms disappeared though

Thanks for such quick responses, yeah exactly the fact the symptoms have completely disappeared really has me confused. I'm afraid to bring it in because I know they'll want to change the MAF and a bunch of non-issues until they finally figure out what the actual issue is, meanwhile costing me a small fortune. Vacuum leak was my first suspicion. For a ****ty engine, it sure runs great now. It was only this one instance that this happened. Car is smooth otherwise. Those codes couldn't have all been accurate.

Im having the same issue with my car, Its been happening on and off since i brought the car in for new rear brakes and rotors, new control arms and sway bars.
I have some codes if you know what may be causing the exact same problem he had
p2004 p2009 p2032 p2061 c1036 c1210 c1173 c1172 c1310 c1038 c1027 c1029 c1022 c1024 it keeps happening after i've driven to work and it sits for 8 hours

Did you find out what the problem is. I have exactly the same symptoms and it has happened twice. Replace an oxygen sensor and the MAF. Problem still occurs. If I wait a few minutes it will run normally again. Baffling.
