Engine/Service/Inspection Dash Warnings

[Bazza]

Thanks for the information, is this the type of device I need to read the codes?

Hi, and welcome from me, have a look on Utube for resetting a Zed 3 oil light for dummies you don't need anything but a piece of wire, I went down the device route you have mentioned on Amazon trust me it's not needed.

Cheers, that looks simple enough, just need to find something old I can break to get a wire out of lol

 

[Bazza]

I did buy one of the devices you mention used it twice it then broke

Vote of confidence for it then lol

Just went out in the car for the first time since driving back from the dealers and the engine light came back on.... Guess I'll hold off sorting the inspection light

You really need to read the code(s) it has set to see whats going on with the EML lighting up again, the dealer obviously just reset the light and fobbed you off without fixing what the cause was. Wouldn't surprise me if you find a camshaft sensor code or maybe an airleak on the rubber intake side before the throttle body.

 

[Niall26]

Yeah it's on the to buy list, was hoping I didn't need to rush into getting it if the dealer sorted this

Think I'll get it sooner rather than later though since as you say the dealer could just be trying to fob me off

 

[colb]

Let us know what model and engine you have in yours, that will be a help when explaining where to look for things when we know what code(s) have been set. If you are not sure have a look here for your cars build details.

Hi I have the same problems with these lights on what is involved changing cam and crank sensors ? Geoff

Cam sensor is in the front of the cylinder head upper timing case cover held in by a small bolt on 1.9 engines, they do differ between M43 and M44 engines the latter having a longer electrical lead.
M43 diagram here https://www.realoem.com/bmw/enUS/showparts?id=CM12-EUR-12-1999-Z3-BMW-Z3_19&diagId=11_6195
M44 diagram here https://www.realoem.com/bmw/enUS/showparts?id=CH73-USA-09-1998-Z3-BMW-Z3_19&diagId=11_2685

Crankshaft sensors down on the bottom of the engine left hand side towards the rear similar to camshaft sensor 1 bolt fitting.

May be easier to get at this one from underneath the car if you need to check/chnage it.

Before paying out for new sensors and if you do get oem replacements don't use cheap pattern parts get a code reader on the car and see what codes it has set to verify what the cause is.

Thanks for the info, I have a code reader that my nephew down loaded for me when I purchased my 1.9 3 years ago but never needed to use it, .
I will take car out this morning and get light to come on and put my code reader on, do I do anything other than plug it in ? Geoff

 

[colb]

What make of code reader is it?
Are you plugging it into the round diagnostic socket under the bonnet or using the OBD2 socket under the steering wheel if your car has one. If you are using the round socket then you probably have the bmw round to 16 pin obd conversion cable to plug into yourcode reader.
Usual to plug code reader into either socket remembering that the oblong obd2 socket under the steering wheel will only read the engine module whereas the round socket will access all modules on the car.
Code reader will connect to the car and depending on what reader you have you need to ask it to read codes by selecting the command on the reader.
Report back here what you find the codes are.

 

[Geoff Crispin]

It is a BMW one that plugged into round socket under bonnet on 1.9 but not looked at the three, will go out in it shortly and report back. Thanks Geoff

 

[Geoff Crispin]

Forgot to say that the reader is installed in my laptop

 

[Geoff Crispin]

I have socket under the bonnet but cant undo it !
Went on a 5/6 mile trip, start up no lights on but after a mile or so brake fluid light on (but its full) ABS, EML< and the engine shape. On return journey only light on is the engine shape but surely the cap under the bonnet should just unscrew ? getting weak in my old age Geoff

 

[Geoff Crispin]

Laptop on to code reader, engine going,and engine shape light on, plug into round socket in cat, blue light showa up on lead to show its connected but cant get the circles at the top to go black just says its off.
Im a bit stuck as I realy dont know anything about working it, do you ?
Regards

Geoff

OK sounds like you have BMW INPA diagnostics on your laptop and are connecting it via a round to 16 pin obd2 cable to the interface thence to your laptop via a usb cable from the interface to the laptop. When I use mine I plug it in then open up the INPA software with the ignition switched to ON engine not running. If the system sees the car you should see those black circles if they don't show then maybe your usb port is not set correctly for the software and it can't see the car. If I remember correctly it should be set to Com Port 1.
Once its talking to the car then select your model from the menu to load up the module you want to work with.

Walk through here on Youtube for a different model but same for Z3

Hi
That looks very helpfull I will have another go tomorrow the way you have done it and let you know how i get on
Thanks Geoff

 

[Geoff Crispin]

Hi
Tried all that but, but cant get engine and battery circles to go black to enable me to start. When I plug laptop into car the light on the lead is on, turn ignition on but no change so confused as to what if anything is wrong. Any ideas please ?

Geoff

 

[colb]

Sounds like the usb port settings are not correct for Com Port 1 which INPA likes to use. Since you have a light on the interface cable its picking up power from the diagnostic socket as it should which makes me suspect your laptop settings are at fault hence no communication between interface and car. What windows system are you using on the laptop XP Windows7 or windows 10?

Try downloading the available usb drivers you can find on a Google search and make sure its selected for Com 1 port in its settings then give it another go.

 

[Geoff Crispin]

Hi
Windows 7
But all this is double dutch to me but I will have a go

Thanks
