You may need to change your thermostat or coolant temp sensor, If the sensor does not detect proper temp than this could cause ur problem.. A scan tool could help give u the readings.

Signum 56plate 1.9tdci.it goes on limp.mode either after ticking over for 2 mins or just in the midle of driving..then i just need to flip the switch off..on. and its back running sweet for a few min


Because you mentioned tick over I am assuming this tends to happen as you change the position of the throttle which if electronic is a common cause of engine management light and limp mode.if you keep the throttle still whilst driving for any length of time ...you may again experience limp mode the minute you either slow or accelerate as the contacts in an electronic unit are intermittent.my cure is to switch off the engine and pump the throttle pedal hard all the way to the floor and releases several times .this seems to make the contacts connect more efficiently.if this is the culprit it may be worth replacing the throttle module.lastly any limp mode is always recorded on the ecu as an error code.if you want to get answers fast take it to a garage and have them OBD the car to confirm what's really going on.

Shogun elegance ask light comes on and the car goes in to limp mode


Hello

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems.

WHEN I START TO RIDE OFF IT GOES SLOW AND THEN FAST WHAT IS THE PROBLEM .IT START SOMETIME .WHEN I SLOW DOWN PUSHING ON THE STOP IT CUT OFF


You mean sometimes it wont get out of its own way and other times runs like a bat out of hell from a stop ? Sounds alot like a bad Mass airflow meter or it isn't shifting down into first gear. Try manually selecting low gear when you start out and see what happens. Also low fuel pressure or very restricted fuel filter can do this too.

Hi, i have a 1999 bmw 323i and the is not giving me the performance as usual, it wont pick up speed fast, if am going 50mh and i press the break and than press on the gas it wont respond fast at all even...


A few classic possibilities here. First your throttle body sensor may be bad. Second your mass airflow sensor may be bad. Third your fuel regulator may be on the blitz. Also, if your oxygen sensor is going bad you may feel a slow response to your acceleration. My best bet is that your mass airflow sensor is going bad. Please have your car diagnosed at the nearest AutoZone for free.

Car bucks and stalls unless mass airflow sensor is disconnected. Changed airflow sensor and temperature sensor. Also changed air filter. Engine light remains on.


Clear and recheck your codes. You may have another problem that taking off the MAS is masking. Throttle position sensor being stuck is a common issue as well.

With the MAS off the car goes into "limp home mode" and everything gets set to base settings with no active input from sensors.
Also check your fuel pressure on the fuel rail.

Good luck and be careful.

Sounds to me like the mass airflow meter, cutting in and out. When faulty it can completely shut a car off, and also ingauge limp mode. I hope this helps. Let me know how you get on.

may be a build up of carbon, there are cleaners for your system to clear out carbon deposits and burn higher octane fuel and give it a good run.
