2002 BMW 325I Problems

What owners report

Owners of the 2002 BMW 325i most often describe two problems: rear tail, brake and turn-signal lamps that stop working, often with melted wiring or sockets, and power window regulators that fail and leave windows stuck down. Air bag complaints are also common, many tied to Takata inflator recalls. Many reports come in between roughly 60,000 and 130,000 miles, and the lighting failures are usually intermittent at first.

   Rear lights stop working, wiring melts

   • 42 complaints (26%)
   • median 93,704 mi at 9.0 yrs old (33 state mileage)
   • 12 mention a crash, fire or injury
   • filed 2009–2019

   Complaints describe the tail light, brake light or turn signal on one side going out or working intermittently, with a bulb-out warning on the dash. Several owners found melted wire insulation, burnt sockets or a charred housing when they looked, and one reported a small fire at the turn signal. Dealers and mechanics told some owners the ground connection in the rear light cluster is inadequate and recommended adding a ground or replacing the housing, bulb carrier or wiring harness at the owner's expense; some owners were told their car was not covered by the rear-lamp recall. Reported from about 30,000 to 190,000 miles, most often between roughly 60,000 and 130,000 miles after years of use.

   What to check: With the lights on and the brake pressed, have someone watch all rear lamps while you work the turn signals, and look inside the rear housings for browned or melted sockets and wiring. Ask whether the rear-lamp recall work (11V438000) was done and whether the ground or housing was repaired.

   “2002 Bmw 325I, turn signal failure resulting in small fire. 1- symptoms: car turn signal failure warning light illuminated. 2- upon removal of housing I noted that the light operated intermittently which caused me to investigate further. Upon removal of the plug or wiring harness I noted that the brown wire showed evidence of melting of both wire and metal male plug end with black residue. A simple internet search revealed that Bmw issued sib number 63 03 06 to mechanics. …”

   “Brake light failure came on in my 2002 bmw325i. I went out to look for the failed bulb, but the brake lights were all working. I noticed that the left side, rear lights were much dimmer than the right side. I went to the mechanic and he showed me a burnt wire and molten plastic connector from the rear light cluster. He said that this is a known problem with this car because Bmw did not provide enough ground to the cluster and overtime the extra heat generated by the current will burn the wire and connector. …”

   Power window regulators fail, window stuck

   • 15 complaints (9%)
   • median 64,000 mi at 7.9 yrs old (11 state mileage)
   • filed 2005–2016

   Owners describe a crunching or grinding noise from a door window, after which the glass stops moving and often stays down and cannot be raised. Some report three or four regulator replacements across different doors, and a few mention the sunroof or sunshade clips failing the same way. According to the complaints, repairs were sometimes covered under warranty or a certified pre-owned plan and sometimes paid by the owner, at a few hundred dollars per window. Mostly reported from about 35,000 to 110,000 miles, often years into ownership.

   What to check: Lower and raise every window and the sunroof several times and listen for grinding or a slow, laboured movement. Ask which regulators have already been replaced and keep the receipts.

   “On my 325I, I have had three to fix the power window regulator three times for two different windows, today I took it in to fix the problem a fourth time and for the third window. Three of the fixes have been under warranty ' unfortunately the latest one is not covered. Even under warranty, it is inconvenient and this time when it happened I was four hours away from home and I had to drive with the window down ' in the cold ' to get home. Thank goodness it was not raining.”

   “I've read several same complaints re: window regulator failure, so am adding this report for record: I have replaced two rarely used rear window regulators that were diagnosed as faulty (both rear door passenger and driver side) on my low mileage 325I 2002 -- each was after warranty expired (dates: 7/07 and 9/09). The window mechanism simply stopped responding/working, produced a grinding noise when deployed, and would not raise back up from a previously working down position. …”

   “On september 7, 2018 I lend my car to my son so he could run some school related errands he needed to attend to. That day he had also taken my daughter with him as they were going to have lunch after he had finished all of the errands he had to do for that day. Around 3:10 p.m. My son got into an accident which had caused both front airbags to deploy. Soon after the accident a noticeable cut was noticed on my daughter left cheek which was caused from the air bag deployment.”

   Brakes

   ABS and brake warning lights, speedometer loss

   • 6 complaints (4%)
   • median 112,970 mi at 10.0 yrs old (5 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2010–2014

   Complaints describe the ABS and brake warning lights staying on, sometimes with the speedometer dropping out, the traction control inactive, or a loss of ABS assist during hard braking. Diagnoses in the reports point to the ABS module or a steering-angle sensor, and dealers quoted module replacement that some owners declined. Reported from about 95,000 to 170,000 miles.

   What to check: Confirm the ABS and brake warning lights come on and then go out at startup, and ask whether the ABS module or wheel-speed sensors have been replaced.

Buying note. A 2002 325i can still be a sound car, but budget for window regulators and rear light housing or wiring repairs, and verify that all open air bag recalls were completed before purchase.
