Hi Todd ive got a bmw 318i and twice now when im driving at about 70ish mph the triangle light with an arrow going around it flashes on and the engine tries to stop or slows down im not quite sure what its doing but its like its chugging a bit can u tell me whats wrong please

Have you checked the Angle Sensor

Check your Other Post....

The following are descriptions from the Mini-Cooper S owner's manual.

Service Engine Soon "?If the warning lamp comes on
either continuously or intermittently, this indicates a malfunction in the emissions-related electronic systems."

EML light: "Engine electronics ?Malfunction in the engine electronics. You can continue to drive with reduced engine output or engine speed."

Triangle circled by an arrow: "Automatic Stability Control plus
Traction (ASC+T)/Dynamic Stability Control (DSC)
?Indicator lamp flashes: System active: drive and braking forces are regulated.
The indicator lamp stays lit: ASC+T/DSC switched off with button or defective. In the event of a defect: please have the system inspected at your MINI Dealer."

First, inspect the belts to make sure none failed at high RPM. If one broke, inspect any cable or hoses in the plane of the belt to see if there was any damage (e. g., a ripped wire in the ASC+T/DSC system). Second, get a readout of the engine error code. (If you get indications of a major vacuum leak including rough idle, look for a blown head gasket.) If you get something else, please post the results in a comment so we can go to the next step.

Please refer to the owners manual for red light warning, it can be low oil pressure or hot engine or emissions system. If you don't have an owqners manual you can find used ones on eBay Motors.

Did you use LED replacement bulbs or standard bulbs?

If you used LEDs then THAT'S you problem.

Either the fan switch on the engine or the fan relay is at fault. Replace both for they are inexpensive to replace

hi, in my book it says, the (!_) with the exclamation mark in middle is..low tyre pressure, and the triangle on is the stability control and traction control..you should have a button on the centre consol to turn this on and off if it does not turn off you will have to take it to main dealer as there is a fault with it hope this helps

On a 1998 3 series (E36) BMW, this indicator lamp is for the ASC+T = automatic stability control plus traction. It should go shortly after the ignition is switched on implying that the system is OK.
If the indicator lamp fails to go out after the engine is started, or comes on in the course of normal vehicle operation it means that the system has malfunctioned. The vehicle remains operational, but without ASC+T. You a have an 2001 3 series (E46), but I suspect the indicator lamp means the same as the E36 3 series. Look in owners manual under "indicator lamps"

The fault you are getting and with dealers recommending replacing the throttle body, it sounds like you have a defective engine wiring harness. I have seen quite a few of these. usually we will put a throttle on the car and then recommend an engine wiring harness if its not fixed. Not the best way to diagnose a problem but its almost impossible to find a fault with a multi-meter or an o-scope.It does not sound like the DME (engine computer) has failed but it could be a possibility. Also if you adjusted the throttle cable when changing the throttle. you will end up with the same faults. I recommend taking the car back to the dealer and being patient with them. this isn't the easiest thing to fix but most bmw dealership will take the time to make sure your vehicle is fixed correctly and will help you out any way possible

I seemed to have run into a website that you might want to check out. about a 1/4 the way donw the page

MMM THOSE ARE WEIRD CODES,THEY SHOULD BE P 0000 ETC... THE ONLY THING CLOSE WAS CODE 61 ( I FOUND CODE 62 WHICH IS MISSFIRE )

TRY ANOTHER SCAN TOOL
