No Error Messages, Temporary Limping

lagos e92 m3 · 05-05-2018, 07:35 AM

Please my car seems to temporarily limp when i drive slow at speeds of 20-30mph between 2nd and 3rd gears. Even when i kick down it doesn't accelerate. Its a bit dangerous and this scares me at times when the car isn't able to accelerate properly. How ever i have found some sort of solution which includes me turning off the ignition or pressing the M power button. Please what can i do?

Read out the codes. It could be: a bad spark plug, coil pack, or throttle body actuators....

Find a scanner and read it out first. The above listed issue are all very common problems.

please what do these codes mean.

10212 plausibility vacuum pump mastervac (HEX) 27E4

P2098 POST CATALYST FUEL TRIM SYSTEM TOO LEAN BANK 2

10134 AUX TRANS FLUID PMP CTRL CKT

10183 LAMBDA SENSOR AD DIAGNOSIS TRIM CONTROL BANK 2
HEX(27C7) INTERMITTENT

10134 ENG. EMERG. PROGRAM ACTIVATED (HEX)2796

11095 ENG. EMERG. ACTIVATED (HEX)2B57

AFTER CHANGING MY ACTUATORS MY CAR WENT INTO LIMP MODE AGAIN. ALTHOUGH THIS CLEARS WHEN I RESTART, I PUT A SCANNER ON I GOT THESE CODES AGAIN

The 27e4 indicates an issue with the secondary vaccum pump for the brake booster. That can be a bad pump, bad vacuum sensor, or vacuum leak in one of the booster lines. The accompanying lean codes could result from that issue if indeed there is a vacuum leak which is introducing more air into the engine. 1st thing, do you hear the vacuum pump running a lot, especially after hitting the brake pedal? It will be a humming of an electric pump coming from the area of the master cylinder, driver fender well area.
