SOURCE: Yellow engine warning light and car has rough idle

to get trouble codes you must hook up a test tool called a scanner, this interfaces with the computer in the car and pulls the codes from the computers memory.

Purge Control Valve Problem

The "Purge Control Solenoid Valve" is the "Purge Control Valve".

Rough idle is a typical symptom of something amiss with the purge control portion of the evaporative emissions system. It could be the valve itself is not operating correctly, the evap canister (vapor canister) may be leaking, or full of raw gas instead of vapor, or maybe even the purge control valve is getting a faulty signal from the ECU.

The soleniod is checked by applying a voltage to it and checking to see if it closes, or opens (I'm not sure if its un-energized state is normally open, or normally closed). If the valve is bad it is a no-brainer to replace.

The vapor canister can be removed and checked to see if it is full of raw gas (not supposed to be), but checking it for leaks is a bit involved, and probably requires equipmet not normally owned by a home mechanic. Vapor canister failure on cars with a lot of miles is common. Replacement is the fix.

Of course if the ECU is not sending a purge signal to the valve correctly, figuring out why may proove difficult, and possibilities could even include a faulty ECU. I expect this is unlikely though.

It's a $20 part. I first would change pcv valve because it can give same error if it's plugged up. You can always remove it and shake it. It should rattle around real easy. If not, it should be repalced

My Audi A4 2001 had a coil failure which switched on the engine management warning light. I have changed the coil and car is running fine but I want to switch off the warning light. Can this be done...


u have to get the error code in the controller reset. it needs special equipment which is at the dealer and service centers only.

So sorry but you will have to visit them, but i hope they don't charge for this, as they don't even have to open the hood of the car.

The orange engine warning light is lit and the engine surges between 4,000 and 5,000 rpm


The first step is to delete the fault code:
Disconnect + wire on the battery for one hour. Turn ignition ON but do not start the engine. Leave it on so the throttle resets automatically. Turn ignition OFF and then start the engine as you normally do. Go for a 15 minutes drive, Audi reccomends to not let the engine idle, go for a normal drive so the ECU reads the values from all sensors again and remaps the ignition and fuel timing. If after all this the Engine Service light stays ON the engine needs to be diagnosed by an Audi workshop as it could be a lot of things, from a faulty coil pack, to an oxygen sensor or maybe a coolant/air temp sensor...

Audi A4 Electrical Fault


Get it to the dealer or a specialist auto electrician and find out why the engine management light is on. That and the other warning light is telling you there is a significant problem with the engine!! Not dealing with it WILL cost you a LOT of money!!

Esp dashboard warning light is constantly on... TT quatro 2002


warning lights are usually got to do with the electronics in the carm so you should go to a mechanic and ask him to check the cars electronics which is free and he will probably say your electronic wiring is smashed the cheapest thing to do is rewire your car it would cost 100-250 euro where as if you got the car comprimised it would cost 700-900 euro
