Emissions light

Jus71n · 03-30-2017, 02:00 PM

Hi all,

today my 320d emissions light came on? Any ideas on the usual cause of this? no errors in the vehicle status screen, seems to drive ok?

vorph · 03-30-2017, 02:26 PM

Diagnostic

Getting fault code read tomorrow, was just seeing if anybody else had the problem and what it turned out to be

You have been hacked by VW?

Didn't they just take the emissions warning light out of their cars

That's not an emission light, it's the engine management light. It could be one of a thousand things.
Get it read and you will know pretty quickly what's potentially wrong.

It might even disappear by the morning.

Diesel particle filter.
They can get blocked if you done a lot of short run abouts. Give it a good booting up the motorway for 10 mins or so. This usually clears it. If it doesn't go out then it might be something else.
Just something for you to try.

P.s the car hasn't gone into limp home mode has it? As in -loss of power ,30-40 mph only achievable.

SteveChester · 03-31-2017, 06:09 AM

Take it out and give it a good thrashing !!!

Jus71n · 03-31-2017, 06:18 AM

took it for a good run last night, no joy?

no car isn't in limp mode still full power

Sounds like the Basil Fawlty treatment!

simon the pieman · 03-31-2017, 06:40 AM

Another guess might be EGR valve (exhaust gas recirculating valve). Diagnostic will tell.

This should be done daily

It's nothing to do with dpf, that'll come under drivetrain accompanied with a yellow warning triangle.

These is something less severe and can be read by a cheap code reader.

vadimo · 03-31-2017, 01:47 PM

Pretty sure if dpf is struggling it's the worst advice to the OP to thrashing the car on motorway, do the motorway journey but easy.

Is your mpg changed?

Jus71n · 03-31-2017, 01:51 PM

Everything seemed normal, power performance & mpg

took it in today, my mechanic accidently pressed the 'clear code' button instead of 'read code' so light is now off and up till now hasn't come back on

gutted not to yet know what the fault was

I think the fault might be logged in the car so BMW could still read it.
