BMW parts reviews

I use Red Line in everything. The M3 gets 15w-50.

I use the 5W-40 in my e46.

Shell Rotella T6 15w40, has worked fine in my F800GS for 40k miles.

Castrol semi synthetic Actevo for my F800st.

I've always been a Castrol man for my BMW car.

Well I decided to try Motorex on my F800 GS, bought the 4T Top Speed full synthetic, in 15W50, boy I cant help it but recommend this oil, the gearbox is so smooth and silky.

If you wanted to try an additive I would recommend Red Line. I had a BMW with tank level issues and it corrected it

Running LM 10W-60 full synthetic in my S14. After 5000miles I can't say one is better than the other. Does the job, still has healthy color. Motul was also fine, no debris in oil filter, normal discoloration.

Add me to the club of owners who are being hit with $8K+ repair bills because of the faulty ac compressors in the 2014-2015 i3.

Recently, a random sound started after I turned on the a/c, so I immediately turned it off. No warnings or notifications came up about anything malfunctioning. I took my car in for a diagnostic test and nothing came back. They checked off that the a/c was working properly.

Not satisfied, I eventually took it to another dealership and they said that they couldn’t reproduce the problem. I finally was able to take it to another BMW dealership when the sound came up recently . The service attendant immediately noted that it sounded like the compressor was going out.

The next business day, I took it to my normal BMW service center and they set it up to be looked at. After I explained the problem with the compressor they quoted a diagnostic charge of $170. They connected it to a diagnostic code reading device and saw codes for the compressor. First, they quoted me $3,200 to replace the compressor and parts (labor included), but then after I approved the service they called me back a few hours later and told me they needed to look further into the problem, and that it would cost an additional $600.

They concluded that metal broke off of the compressor and contaminated the connecting parts.

The new repair total was now $8K, with over $4K for labor. The compressor, condenser, and HV battery accumulator need to be replaced. A flush is also needed. How was none of this discovered before I told them what to look at. Eventually they will need dedicated EV specialist.

I immediately called BMW’s EV department for assistance with this issue. This is clearly a known issue. How did they not catch this before it was even a $3K issue, my car has had multiple diagnostic test run.

A few years ago, my last car (C-Max) had an issue with the transmission, but the manufacturer replaced it at no cost because they acknowledged the problem with that particular model. I didn’t have to call them at all. They even gave me a loaner car. I have loved driving my 2015 i3 for the last 3 years. After this, I think I may be a “one and done” BMW owner.

If you are currently thinking about purchasing an i3, refrain from purchasing any i3 model with this common problem.

Main problem with depos, is they aren’t always sealed properly, so the headlights will have moister inside.
