I have a 92 318is supercharged with a manual transmission. I saw an error code pop up on my dashboard while driving it and then it went away. Engine was still running great no odd noises or symptoms at all and still aren't any. One day i realized that when driving it the light stays off but when i get up to and above 4000 RPM the light comes on and stays on no matter what gear i'm in. But when i let off and it goes below 4 grand the light goes off.
The weird thing about it is i go to check the code and the only code it's flashing at me is code 1238. I have checked on a couple forums, various sites and have the Bently 3-Series Manual and they all show codes in order from 1234:
1234
1237
1242
So what is code 1238?? I can't find it anywhere! I was thinking it was maybe the supercharger causing it. I haven't seen any other 318's supercharged, so i'm guessing the engine wasn't designed to have one. But at the same time i'm getting a whining noise from the passenger side and i know the fuel lines are on that side. I thought maybe the engine isn't getting enough fuel because pump maybe going bad or filter just old and slightly clogged. I'm going to get the fuel pressure tested this week to see what it's at. I'm brand new to BMW's so these are all just ideas i'm kinda throwing out there.
Any and all help would be greatly appreciated!
