My 2001 e53 clicks one time when I try and start it and that’s all. When I try and jump it it will start but not stay running. I’m just not sure exactly what to check, and or why this would be happening. My battery is good, I don’t think it’s my alternator. I’m thinking it’s my starter or my...

Dont replace your alternator before you watch this video

Ok, so today I decided to replace my alternator, put the new one on, put everything back together and when I went to turn my car on I get nothing, no crank or anything. Lights and radio all turn on, car wont crank. So I thought, maybe it's a faulty alternator so I put the old one back in and...

Hello, I own a 2009 328i that just reached 106,000 miles. I recently replaced coil #4 because of a cylinder misfiring. Last night was unbelievably cold, to the point where when I looked at my car this morning the headlight washer covers had burst off the bumper from the frozen ice inside the...

Hey! I have been trying to find the coolant leak on my 99 e46 for a few weeks now and I don't know what it could be. After getting a coolant system pump I found the first leak, which was at the thermostat, and successfully fixed that by changing the thermostat housing gasket. Now it's leaking...

Electrical issues are the worst. So I turned my car on a few days ago, and every single light on the dash lit up. Im getting specific errors for DTC, CEL, drivetrain, passenger airbag, brake light, ABS, and steering is super stiff. So I immediately thought it was the battery so I had it and...

Hello all, I am a new member, with a new (to me) BMW, and a number of the previous owners issues (like many here). I purchased a 2004 ...... wait for it..... 745I N62B44A :yikes::yikes::yikes: as my first personal vehicle (ive shared for years, but never enjoyed my own). I know, from reading...

Hi guys, Is $690 for an alternator replacement (with Bosch rebuilt) and the diagnostic work to figure it out a fair price? Or am I being burned here? I've worked with this mechanic several times, but now that he has gotten pretty big, I feel like he no longer feels the need to hook up the...

Hello, I got some really nice help last time, so I´ll post my second big issue! :angel: Problem: When I drive, all of a sudden Dynamic drive failure turns on, and is often followed by tire pressure, active sterring, abs, gearbox malfuction, etc. I scanned with my OBD2 senor and alot of...

Hi Pundits and fellow BMW aficionados, I changed one of the spark plugs (one to the left of valvetronic motor) last evening and the other plugs I changed sometime ago. This coil was very hard to do before and it had a rough idle for the past few days, so I took time out to do it yesterday. I...
