A twin to mine, but yours has a few extra options (rear shade, autodip mirror, and heated seats), and I drive the HECK out of mine, too.... except I don't know what color interior you have (sorry, not going look up the code). Yes, the door panels are STILL on my list to re-do. They suck.
The idle is set to 950rpm, so it is probably about right, but I have heard that, while very rare, air leaks can possibly cause some trouble.... I am kidding, I know all about the vacuum system, and not by choice, that would be the first place to look for drivability problems.
I am still trying to get used the LONG throttle pedal, even after 5 years plus, and it drives a lot better when I am not tentative with the input. This is really noticeable when I drive any of my other cars and then back the M5 (which I drive almost every day). It really is different.
My interior is black
Idle is really 950 rpm? That sounds high.
Haven't really notice any issue with throttle pedal... Will definitely have to look into the shitload of vacuum hoses though
What a great car! I would call that on the low end price wise for a similar car here in the US, as well.
It sounds like you are pretty knowledgeable about next steps on most of the problems you described. I would suggest checking on your variable resonance system on the airbox, which can really turn these cars into dogs under 4500 RPM as described. In fact, your description of the power and being much stronger above about 4500rpm could be exactly that failure. The variable system is responsible for creating something like 40wtq at the wheels at low RPM!
Do you feel there is slack or wasted travel in the throttle pedal? Sometimes a throttle cable adjustment is needed.
Side note: I’m guessing the E36 is a Euro?
I did not know about this variable resonance system... I found some videos and it seems there is some kind of test to check if it works, I will try asap.
However if it does not, what is the solution? Change the part?
And yes my M3 is a Euro model, US models are fortunately not existing outside of the US
Funny I recall seeing this car, as it was only up pretty briefly and I thought it was a great price (I check Japanese M5 listings regularly since I'm living in Japan at the moment). My M5 is still in the US, but I'd love to bring it to Japan. What BMW shop will you be taking it to for repairs?
It stayed about 2 weeks I guess, indeed I jumped on it quite quickly.
The shop keeper who sold it to me is actually a super nice guy who use to race E30 M3, and is still organizing some track day session in Fuji Speedway. I went there last week with the M3 and we had a great time.
I am maintaining my cars at Bitte Motor Works, in Chiba, not far from Disneyland.
Actually I am hanging with a group of friends with who I am doing Endurance racing and altogether (7 or people now) we are maintaining about 12 cars there, all ///M, Alpina and Porsche, and 3 BMW race cars... So let's say we benefit from special conditions. Service is excellent, prices are super reasonable and I can bring my parts (never buy BMW parts in Japan...).
Been in Tokyo for a year and a half, seen a broken down E32, a couple E24s, a pristine E28 M5, and not a single E34. Actually saw my first E46 M3 last week, so it seems M cars are just rare in general.
Funny, I see M cars everywhere in Japan
Living there since 8 years though, and frequenting a lot of BMW fans so I might be biased :p
