ENGINE EMMISSION AMBER LIGHT

[peterdorey]

The Amber Engine & Amber Brake ABS & RED lights came on & said if they come on again we'll have to investigate (sounds expensive!).

The 2 sensors would be crankshaft and camshaft, they are responsible for ignition timing and fuel injector timing. Sound like what we call here in the states a type "B" MIL light (OBD II) as these take 2 occurrences in 40 drive cycles to set a DTC code.
Did you notice any hiccups right before the light came on?

Take the bulb out. Problem solved. Bloody modern nonsense.

[peterdorey]

Hiccup was probably when reversing out of a tight space, engine falter or something but runs fine now.

I agree with Modern electronics rubbish, whoever set the tolerance at VW?!

What use is the warning when it can be cleared, but only by the dealer!

[stevieturbo]

There are a variety of diagnostic scanners that can clear fault codes. Some cheap for the DIY user, and some more expensive, for the more able.

It doesnt take the dealer to clear the codes.

Be very wary!!!! I have a corsa and this also has a problem with the engine managment light. All I can say is check every possiblity before you have anywork done. I have spent hundreds of pounds before I found this website.

Everytime the light came on I went and paid £30 to have it put on the machine and then paid out for parts and labour, and from reading posts on this website half of the things I got I didnt need. So far my ECU has found faults throttle position sensor, air flow sensor (I had these changed twice!) It also read cam sensor and loads of others I cant even remeber.

My most recent post is corsa gsi every problem you can think of!!!! The guys on here are better at solving the problems than my mechanic and they haven't even seen the car!

Where mechanics get it wrong is usually when they try to short cut the diagnostic flow charts, If they leave out just one step it will result in the wrong diagnosis. allot of the sensors are interrelated and if one goes bad the P.C.M. will use other sensors as a "best guess" backup.

So when the mechanic plugs in a scan tool he may see a sensor out of spec and completely miss a sensor that isn't functioning at all, thus replacing the wrong sensor. Never ignore the emissions light as catastrophic engine failure can occur,holes blown through a piston from detonation, etc. Removing the bulb is the wrong answer.
