Obd port not Connecting

[Jack]

Just wondering if any one can help
My obd scanner won't connect I have tried on both ports

Z3 1.8 2000

Reader powers up ok at both ports just won't connect

I have read about a fuse to check ?

What else should I check?

Reader is working on other car just wondering if it's not bmw compatible

Seems that there's alot of people with the same issue

What are you trying to read from the obd port as it will only read engine codes. The 20 pin connector under the bonnet is the one to read most codes.

 

[Jack]

Engine light is on
I have tried the 20 pin still have a communication error

@zedonist will more than likely be able to shed some light on your problem.

 

[zedonist]

What scanner and connector are you using?

 

[Jack]

Hi mate
Mac tool e97 plus a 20pin adaptor
I also have a 16 pin under steering wheel that don't connent ethier

Need to check fuse 26 I think I read

Bmw only put the obd socket in to comply with new rules and regs that came out at the time and even then only made it as functional as the regs demanded so like Brian says you can only connect to the engine module and even then I think it is still limited to the point it is practically useless. 20 pin connector under the bonnet is the one to use and ignore the obd socket as it is a waste of time. Are you using an obd to 20 pin adapter like this one;

As most generic code readers should be able to read something but you maybe unlucky and have one that doesn't.

 

[Jack]

Yip that's the connector I got
Was thinking of getting the bmw c110 reader but want to make sure it's not something else first

 

[zedonist]

if your car is starting it can only be one of two things, either the port is broken or reader is not Compatible.

 

[Jack]

Car starts and runs lovely
Any recommendations on reader?

@zedonist posted a very good thread on using a wireless ELM reader which you can either use an iPad (wifi version) or Android (Bluetooth version) tablet that work quite well with such apps as DashCommand, Torque etc. that are quite inexpensive really and offer a lot more functionality over the little handheld readers, kind of half way between them and full blown PC diagnostics such as INPA and Carsoft.

Ok so bit the bullet and got a elm327 blue tooth obd2 and also the c110 scanner

If they don't work then I am at a loss

 

[zedonist]

Let me know if you get problems, will talk you through it, the Bluetooth Elm327 is for use with Android devices btw. If you are using apple you will need the wifi version.

 

[Jack]

Yh I was not 100% sure so got both I have a iPhone but also a andiod tablet

Knowing my luck it still won't work

 

[Jack]

C110 works woop woop
Now to look up the codes

Best thing is it was only £38 and also will reset service lights and abs

All help much appreciated

 

[zedonist]

Well done Jack, glad it worked out, plus you git your Elm devices coming which will give you some apps to play with

 

[Jack]

Yh that's turned up to just need a play with it tomorrow
Recommend any apps?

 

[zedonist]

Dashcommand, REV, EOBD Facile, Torque
