Hi

Is there any one fitted an On Board Computer to a M 40 318i E30. Is there any thing different and what coding plug is the correct one.

Thanks

the coding plug you want is the 3 3 type.

It should all fit fine. I'm sure there's a few guys here that's done it.

Datourer, I thought it was a 4-2 TYP?

You may be right, i've been using this as a guide.

E30 318i 3-3 TYP
E30 325e ('84-87) 3-8 TYP
E30 325e (88 ) 4-4 TYP
E30 325i ('87) 3-1.2 TYP
E30 325i ('88 on) 4-6 TYP
E30 M3 3-1.1 TYP
E28 528e ('85-87) 5-8 TYP
E28 528e (88 ) 5-1.3 TYP
E28 535i 5-6 TYP
E28 M5 6-4 TYP
E24 635Csi/L6 ('85-87) 6-2 TYP
E24 635Csi ('88 on) 6-6 TYP
E24 M6 6-4 TYP
E23 735i/L7 ('85-87) 7-4 TYP

I know these are US spec' cars but i think it's all the same

I've had a quick look here, and it shows the 3-3 TYP as for a 316i/318i, but the engine code says M10

318i/318iKat is on there on it's own.

hi i fitted a obc to my 318 m40 cab no problems and was vert straight forward...my only problem is the part that works the alarm code part of the loom(one of 2 plugs that connects to the main junction box)all was well untill i switched off the engine and it kept running even with the key out,i have disconnected that part .......i am running a 2.5 ltr coding plug it works fine but the readings are not accurate...im waiting to get the right one or swap with someone who needs a coding plug for a 2.5 ...........................so gents have we sorted out which is the right coding plug for a 318/m40 engine so we know which one to get

318is uses it's own unique coding plug 4-1 TYP.

Datourer, I assume you found the coding plug list from the above link, the link doesn't take you straight to the list, it's in DIY somewhere.

Hi

Thanks every one. I notice the correct coding plug for the M40 unit is 4.2. as Simon suggested. I hope I can get one from a BMW dealer.

Post Thu Apr 14, 2005 11:18 am

they are still available, i just bought one for my 2.0

Post Thu Apr 14, 2005 5:23 pm

And cost a bargain Ãƒ”šÃ‚£42 !

Post Thu Apr 14, 2005 5:42 pm

Contacted the local dealer today. According to them 4-2 coding plug is not available. Any suggestions as to what is the alternative.

Thanks

Hi Gazza

Well done. Coopere BMW could not help me with the original number. Is the part number correct or is it a superseeded number, as I would like to order one.

Post Fri Apr 15, 2005 4:48 pm

it is a up to date and current number ....some dealers just cant be ars*d to look it was not on the bmw gb system but is still shown in stock in germany
