JUst got check engine light yesterday:

P1476 - Evap Control System LDP Malfunction/Insufficient Vacuum
P0306 - Misfire Cylinder 6

98 A4 2.8 30v by the way....

I have some idea what it could be but can anyone help me out?
Anybody had these codes before and solved the problem?

Thanks guys

 

Can Anyone help me with this plz?

 

The evap code could be a bad gas cap or pumping gas with the engine on or it could be a bad purge valve.
For the misfire, check ur plugs first, if they're good, switch wires with another one and see if the misfire follows. If it follows, the wire is bad. If the misfire stays, it could be a bad coilpack or bad timing possibly.

 

For the misfire, is it normal to have a little bid of oil between the gap? also there's a little bit of black residue on the bottom of it......
For the vaccum problem, what's an LDP malfunction'insufficient vacuum? my gas cap is closed and I don't fuel up with car on....I'm really confused lol

 

Oil on your spark plugs sounds like piston rings. You are definitly getting oil into the combustion chamber which is never good

 

LDP is the leak detection pump. It tests the integrity of the fuel system to make sure fumes aren't escaping into the atmosphere. Without a VAGcom, it's extremely difficult to diagnose because you'll need to short test the system to check it. Often that code means you have a bad LDP or the lines going to and from the LDP are clogged or kinked. The LDP is located in the RR wheel well with the charcoal canister.

P0306-misfire, cylinder 6: As for the misfires, oil on the spark plugs can cause misfires, but the easiest way to diagnose it is to first swap the coil pack to a different cylinder on the other bank. If the misfire follows the coil, replace the coil. If it stays with the original cylinder, try swapping the spark plug. If the misfire follows the plug, replace it. If it stays with cyl. 6, you can suspect the oil on the plug might be the issue.

Check to see if there is oil in any of the spark plug wells. If so, you'll likely need a valve cover gasket with spark plug well gaskets. Oil in the plug wells can cause misfires.

 

Allright thanks guys, I'm going to replace all spark plus and wires I think that might be it. As far as the vacuum problem I need to take it to my mechanic sounds too complicated for me to diagnose it.
Thanks again...
