Hello all,
I recently bought my first Audi A2, but unfortunately I don't think it was the bargain I was looking for.
It's a 2002 1.6 FSI SE, with Opensky and a lovely full black leather interior, bought for £1150.
Seemed fine on purchase, but the problems started after getting it home. First off the engine warning light came on, so off to the shop to buy a ODB reader, came back with fault codes P1031 and P0404, on top of this water was leaking out of the expansion tank and the Opensky roof only goes halfway back, funny sound sometimes on startup. Time for extensive research and trouble shooting ?.
P1031: activation intake manifold flap for air stream regulation, specified value not reached
P0404: Exhaust Gas Recirculation Circuit Range/Performance
I hear the Opensky problem is common and a difficult fix, I can live without for now.
The water leak seems to be down to a broken seal on the expansion tank, waiting on a new one to see if that solves the problem.
The funny sound on startup, only happens sometimes for a 2-3sec then sounds normal. Sounds like the air filter has been removed, or it's just turned into a diesel engine for a few seconds. Anyone know what this is?
P0404: So after some research I decided to strip down the EGR valve, was bit of pain to get off, but got it out in an hour or so. It was quite black inside, so gave it a good clean, then cracked it open to take a look inside. underneath the plastic, I found to stripped cog teeth, fortunately you can just rotate the cog a little to avoid using these teeth. Reassembled and for now, problem fixed!
P1031: After reading every relevant thread on this forum, it seems like this is a bigger problem to fix. Problem with the intake manifold flaps not reaching there required position. I have checked the actuator arm and this all looks normal. So my question now is what can I do, I am guessing the engine needs to be striped down and the manifolds flaps checked and cleaned? I have bought two cans of Wynns Petrol EGR3 just on the off chance it does something, as heard of one report of this working. I am a bit of a budget, and don't really want to be spending the cost of the car fixing it at the garage. How hard is it to get the intake manifold off the car? Heard one guy removing engine mounts, is this really necessary to get it out?
