1998 bmw z3 roadster 2.8 engine light came DTC code p0170

p1188 is fuel pump and p0170 is same problem but with air flow sounds like drawing in too much air and not much fuel. pump might be shot.

hope this helps

P1174 - Fuel trim adaptive malfunction (Bank 1)
P1175 - Fuel trim adaptive malfunction (Bank 2)

black plastic fuse box in the engine compartment on the left side of the car close to the firewall. The fuse is 30 Amp; it is fuse number 32 (the location diagram is on the inside of the lid on the fuse box).

This is almost as expensive as installing a used engine, around $5,000.00 to $6,000.00 the last time I checked with BMW.

try the engine breather pipes first ,if that doesnt work clean the idle control valve

Isn't there a rear sensor by the catalytic converter also?

Error codes not in service manual. presumme dealers can assist you with a pnhonecall for error codes.

BMW SERVICE RESET

Take a small wire, paperclip, or elect wire and bend like a horseshoe. No light or equipment necessary Open the diagnostic data port, the one were the little pacman centre is located. Turn the ignition to position 2, don’t start. Connect pin7 always first and then pin 19. Hold for 4 seconds. Remove wire and settings will be reset. Warning if you hold the wire longer than 10 seconds you may reset inspection intervals 1 and 2.

I’ve done this twice and it definitely work on my E36

Your car is letting you know it needs coolant.

BMW engine light

Comes on if DME engine management system self diagnostic fault detected. Will stay on until codes are called up and memory erased.

With OBD read the code as follows. Turn on ignition key, press accelerator pedal to the floor five times within 5 seconds. The check engine light will remain on for 5 sec , blik off, come on for 2,5 sec, go off for 2,5 sec and fault code will begin to flash. If more than one fault exist 2nd fault code will be separated by 2,5 sec pause. after fault codes there will be a 0.5 sec flash and light will remain off. to read codes again do procedure again.

Canceling of codes. make sure fault code is present (short blink and light goes out for long period), depress throttle pedal for at least 10 sec. read fault codes again and check for code 1444 (no faults stored.)

Check also the following, fuel pump, oxygen sensor, fuel injectors, engine coolant temp sensor, idle speed control valve, mass airflow sensor and too many other things.

yes the light is because of the gas cap being gone (sets code in evaporative emissions system), replace the gas cap, disconnect the battery for five minutes and that will turn of/reset the light, make sure u have the radio code before u do this, if u don't u will have no radio after the battery is disconnected..
