1989 BMW 750iL

[S POWRD]

So I started working at a small european vehicle repair shop last week. Just the owner of the shop and I.

First vehicle I worked on was a BIG Ford Van that had a busted brake line and needed front hubs/brakes, and other crap. It took almost a week to finish.... It was IMPOSSIBLE almost to bleed the rear brakes on that stupid truck.

Second was an mkIV Jetta VR6 that was running like a 3 legged dog. Diagnosed that, bad MAF. Changed MAF and air filter in less than 30 mins bang, next car...

Another freakin Ford van, this time to install a tow hitch, took 4 hours to install due to stuck spare tire. AND the hitch didn't line up so I had to drill the frame. Got that out of the way.

Fourth was a VW fastback that the boss had done quite a bit of work to, but I needed to bleed the brakes on it. Easy as pie, neat little car... First automatic transmission VW had.

Fifth was the bosses wifes truck-to-be. Chevy blazer with a hole in the brake line AGAIN. Got this POS in and out in a few hours, but took quite a bit of time dealing with flaring the brake line that was on there.

Sixth and current vehicle is a 1989 BMW 750iL. This thing is a frickin tank. V12 engine.... 2 MAF's 2 Throttle bodies, 2 air boxes, 2 of EVERYTHING almost... The radiator is shot due to a known common failure with them the upper trans cooler line leaks. It also has problems with the display and we cannot view mileage, the thing has 3 oil leaks, and it smells like mildew inside. I'll post up pictures of this monstrosity, but I've never worked on an engine of this scale. You would think that for a V12 engine it would be SUPER smooth at idle, but it's not. Also the brakes on this boat are as big as they are on my Jetta. And it has some electrical gremlins that I get to work on, it had a MELTED fan fuse, headlights inop and like I said before the display cannot be read. Still pretty neat to work on. I have a feeling I have to disassemble the upper part of the engine and remove the valve covers to fix one of the leaks. YAY for me  But money is money!

MAF = Mass Air Flow

That 750 must have had some abuse. Those engines require a LOT of maintenance, if it doesnt get the proper maintenance, you are screwed. That is the single biggest bitch with the sevens. People buy them that cannot afford them. Once you neglect to adhere to the schedule, the proverbial shit hits the fan, and then the car gets a black eye. Sucks.

Bleeding the brakes on the six was a PITA. The e24 has whats called a "brake bomb". In short its a type of diaphram that is part of the hydraulics. It does NOT like to be bled. It requires a pressure bleeder. Most older bimmers can get away with the manual process.

You have never bled the brakes on this truck then....

And yes, MAF is a Mass Air Flow sensor.
