2004 BMW 525i Questions

red light showing spark plugs need to be replaced. I just had them replaced, but mechanic didn't re-set the light. Now they said the coils could be the reason for the light not going off. I didn't think it was automatic, that they had to reset the service warning light. please help me.

Once in a while the car shows Automatic Transmission Loss and stops. One has to switch off the ignition and restart. This happens once in couple of weeks or so, as soon as I take my car out from garage. Kindly advice the issue and how do I fix it? Dealers tend to misguide you.

2004 BMW 525i Recalls

The insulated connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.

 

Excessive wear may develop on the side bolsters of the seat backrest. As a result, the seat heater mat located in this area may be damaged. If such damage were to occur, with the system turned on, the occupant may feel excessive heat from the area. The heating element may damage or melt a small hole in this damaged area of the seat cover. If this happened, it could lead to the seat occupant being burned. Dealers will modify the seat heating circuit to correct this concern. This recall is expected to begin during December of 2004.

The digital management control (EMC) unit may not have been produced according to specification. The engine may stall and not restart. As a result, a loss of power steering, and after repeated actuation of the brake pedal, a loss of brake power assist will occur. These conditions could result in a vehicle crash. Dealers will install a new (EMC) unit to correct this issue. This recall began on July 16, 2004.

2004 BMW 525i Reviews

I love my car. It is a 2004 525i. I just put M6 take offs on it and it runs perfect. until i recieved the transmission error on the dash. Do i need a whole transmission? BMW said that they would beglad to help at a tune of 6500.00. Any other solution to look at first?

This car is very reliable, I purchased it new in June 2005. The body style is still the same in 2010, so most cannot tell the difference between my 2004, and a 2010. My 525i is a great value. If you check newspapers and car lots, you will rairly see one for sale. They're keepers.

trouble free and an outstanding "driving machine." My next car will be a bmw...Joe Lucas
