Hope this helps

Thanks for that link Toy......nice find. As you can see, this isn't a job for the faint of heart. I can see a dealer owner sending their kids to college on the profit of this project alone.....:stickoutt

had my heater core changed and the plastic pipe that feeds it jan 8th 2009. I got a self employed technician to do the job, there where lots of broken clips behind the dash. someone had the dash before and not put it back properly. not a DIY job. LUCKALY I have a parts car but It took all of two days best of luck.

wow, lul

It can be done without removing the dash as shown in the picture above. It is though, not for the faint of heart, and not for the inexperienced wrencher. Takes about 12 hours. Just for reference, BMW charges in the neighborhood of $3200 for this service....

Didn't you have to cut and then re-weld the under-dash collision bracing to do it without removing the dash? That's a technique that I would personally consider as a legitimate time saver, but I'd have to think about disclosing it to a future buyer. The knee bolsters and supports are a DOT requirement on US cars. Unlike on the e32s and e34s, I've never seen a clean way to pull the core around the tubing on the e31s.

Also, whichever approach you take, removing the seats will make life much sweeter, especially if you're over 4' tall. FWIW

Yes, the tube is cut on the drivers side dash support. It is just as (if not more) structural as the original plus it makes life sooooo much easier. I also highly recommend taking the seats out (it also lets you reclaim all the loose change and stale french fries from under the seats).

Just to give you an idea how things were back in 2002. The previous owner just had the heater core done before I bought it. 12 hours labor @ $89.00 per hour.

interesting that they couldn't repair the uneven seat rail - takes about 15 minutes and $0...
