Honda Accord Water Pump Noise Q. Dear Vince, Hi, Thank you very much for the detailed comments on my door lock problem. Although I had to go to the mechanic for the closed door and he fixed it for me, I replaced the other door 's actuator (drivers side) myself as it was opening with the key. I also fixed the ABS sensor wire and its working fine now. I learned something new that the ABS sensor has polarity although there is only a solenoid coil.

Further, I have some new queries regarding my 1997 528 E39 running 225,000 kilometers, as under the manual says that the automatic transmission oil is permanent filled. Is it true??? Or do you suggest me to have the transmission oil and filter changed? I mean, will I invite some problem unnecessarily by touching this type of transmission? Should I leave it untouched or should I go for a service of this type of transmission? While standing at a traffic light for a minute or so, should I shift the gear into neutral or leave it in drive whereby keeping the brake pedal pressed? What is advisable for the car?

I want to flush my brake system. My car has ABS installed on it. Can I do it myself with your guidance or should I go to some professional mechanic? Recently I changed my engine oil and the service centre supervisor suggested that I must perform an engine flush. Is that really required? Should I do it or by doing so I might end up with some problem which I do not have now?

The service center changed the engine oil, Mobil1 synthetic, but were unable to do a service level indicator reset as they did not have that equipment. I read on the internet at one site UnofficialBMW.com about a simple procedure to reset the lights manually. Can you please go through this site and advise me that I should try the same? Thanks for your time Vince.

A. Rashid, we have an old saying in my business. It's "If it ain't broke, don't fix it". This is a good thing to keep in mind.
