Question about 2001 BMW 5 Series

2 Answers

I have had my 2001 x5 in the shop for a service engine light . First they replaced the thermostat, then the oxygen sensors now they are telling me both catalytic converters are bad. The vehicle has just 82000 miles on it. Could it be possible that both catalytic converters are bad?

    It is a 3.0 2001 x5. I have called the dealership yet again. The code that has come up in the past is catalyst lean fuel mixture in bank 2. I will call and try to get the new code that has come up. I feel like they are just guessing at my expense. Thanks and I will get back to you to let you know what I find out.

    i suggest you call the dealer,some car companies cover the converters for 80k or 100k,so it might be worth it to contact them,and the possibilities of both converters being bad is slim to none,it sounds like this shop is guessing and taking you for a ride at the same time,what are the codes in the vehicle?? engine size?? let me see if i can steer ya in the right direction

Not enough info, but go to another garage and do not tell them what the other shop said.

The only thing that could usually make both converters fail at the same time would be if they were exposed to something bad, like antifreeze from a bad head gasket, burning oil, or some kind of fuel additive that harms converters and O2 Sensors..

Hi, no, they are not related. The oxygen sensor(s) are part of the ignition/emissions sytem and help regulate fuel flow/mixture. The A/C system is self contained and does not affect other engine systems. Mike

The best advice that I can offer is to have your Engine computer scanned and diagnosed by a qualifed sevice technician and find out why the Engine Computer is turning the light on. If the light is on, it is because the computer has stored one or more fault codes. Fault codes NEVER tell you what parts to replace. They only tell you that one or more of the many systems monitored by the computer is operating outside of its expected "Range" or "Window of Operation". It is up to the person performing diagnosis to test the system that is failing and determine the actual cause of the failure and repair as necessary. You can spend a LOT of money replacing a LOT of parts and NOT fix the problem if proper diagnosis is not performed. Fault codes for the Oxygen sensors are RARELY caused by the Oxygen Sensors themselves. Oxygen Sensors are like informers. When someone within the engine management system is not performing their job, it is the Oxygen Sensor's job to rat them out. Replacing the Oxygen Sensors will only cause the new sensor to tell on the same problem. So, in your case, if you have replaced 3 of the Oxygen Sensors, that means that 6 Oxygen sensor have all been trying to tell you that there is a "Slacker" in the ranks! Stop wasting your money and fire the fool!

My 2001 Ford Escape runs rough before it warms up. The check engine light has just come on. I assume it is an oxygen sensor. How do I replace it?


Well, fords are known for multiple O2 sensors... so I would have Autozone do a free diagnostic to see if

1. it really is an O2 sensor - and which one
2. eliminate the power feed to the injection/choke circuit.

I have a 2001 Hyundai Elantra. The engine light


Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

2001 Pontiac Bonneville. Service engine soon light stays on. Went to Auto Zone and had them check out why the service light stays on, does not flash. They suggested to disconnect the battery, replaced fuel...


The scan tool that they used at autozone should be able to erase them and tell you whether they are existing codes or just stored. Hope this helps.

Engine coolant temperature is lower than thermostat


This happens when the Engine Coolant Temperature (ECT) does not reach 75°C (167°F) despite sufficient engine warm-up time.

This happens usually when the thermostat/temperature sensor is faulty, and is bad for emissions and fuel consumption.

The repair cost may vary, even if themperature sensor is not an expensive part, after replacing the sensor there is need to reset the ECU (car computer module).
