Hey everyone got a quick question, Our shop has the oppurtunity to pick up a local BMW dealerships r/s alarm business. I do not have much experience on BMW's and was wondering how complicated doing these on BMW's was. Im just hesitant cuz i have done much other work on bmw's and they have not been installer friendly. Any input is greatly apprecriated. Chris

They are usually difficult to dismantle, and most of the time wires are hard to find verify. you will have to carry the bypasses for the BMW's and have lots of extra wire to sell. most of the time half the wires have to be ran to the passenger side or the rear of the vehicle.
honestly if it were me i would pass.. there is alot of stuff that can go wrong and BMW repairs aren't cheap.

On the rare occassion I get a BMW in the shop, we charge for about 2 more hours labor. Most of the time I quote the customer a price and they say no thanks. Not a problem with me, I'd rather be working on cars that can be done easily and where the shop will make some money. I'd pass on this chance, unless they are paying good money. But as most car dealerships do, I'm sure they are asking for you to give them a deal.

I agree with "diabloed." It's either hack into the stock alarm harness beneath/behind the glove box, or get the "plug in harness adapter" -if using DEI. Then you have to worry about the transponder bypass. If they are going to pay good, then why not.... -------------

If you can get the technical support from the dealership, then I'd go for it. Alot of the times, the installation goes bad because of lack of " correct" information. If the dealership wants you to do it, make sure they understand that you require technical information for each of the installations you get ( this would include wiring schematics & how to take apart the dash & locations of modules ).

The very first Install I did was on a BMW. It wasn't that hard at all, and I saved myself major$$$$$. A guy I know was supposed to do it for me so I bought all of the stuff, but he changed his mind and said BMW's were too hard to do!!! This guy was the install manager at Circuit City for God's sake! I came here and got a copy of the wiring diagram and went to work. I had a few problems, but remember I had never even seen under the dash of a car hardly, let alone cutting and soldering wires. The 550esp works fine no problems. I'd go for it. I have installed 2 more rs an the past month and they took no longer to do than the BMW. Actuall the BMW was done fater, butI did have to use many diodes to isolate the wiring.
