Just noticed the engine management light has just come on but car drives the same. Think I can hear a weird whistle noise ???? going into the garage on Monday.

Try taking the battery off for 20 minuets and touch the positive and negative wires together while there off

Ok I may be fretting but I have started hearing a slap noise every time I change gear. So I stopped and stuck the car in gear and let the clutch in and out, sounds a little like my drive shaft is clonking maybe? Hard to explain, it may be normal and I'm just hearing every noise now and thinking its wrong

Perhaps there is a friendly R32OC guy with VAGCOM who can run a scan for you and see what the error code is that has caused the management light to pop up

Think I'm too far for you but someone may pipe up

Someone local helped me out a few years back so it would be good to continue the favour

Cheers mate! I can hear some loud hissing coming from the rear of the engine, sounds like a pipe leak but I can't see we're exactly it's coming from.

Have a check down the back of the engine, after someone fitted my Simota they left a vacuum pipe hanging and it melted to the exhaust manifold.
Put my engine management on and obviously created a vacuum leak.

Your hissing noise will be most likely the flapper vacum pipe on the rear of the exhaust. Does it hiss when you come off the power in town?

Also have you got a decat?

My first though 2. It can be your solenoid that control the flapper that broke; mine did and it gave the engine light, but car still drove normal. You need to scan your car.

On the rear of the exhaust? A standard one? Because I have a milltek cat back so I don't have a flapper. I have a standard cat, I have never herd this noise before so it must be a vacuum leak, but were the hell is it coming from?

Something else I noticed yesterday when driving was the exhaust seemed a lot more raspy then usual but that could be to do with the temperature outside?

Cheers mate

I sealed the pipe up with a long screw and silicone if I remember correctly, so should be ok

Hmmm that's that ruled out then.

Hi, I had a whistle and raspy exhaust note which sounded like a vacuum leak to begin with but it led me to investigate the exhaust manifolds and downpipes. It's got worse and more obvious so I removed downpipes and it was a knackered flexi. Now waiting on arrival of milltek manifolds and connecting pipes as it was cheaper option than genuine replacement. Engine management light was also on, showing the O2 sensor reached upper limit, due to exhaust blow before the first lambda. Could be your issue too?

Thanks for all the replies boys. I have now sorted the problem, it turned out to be a vac leak on the brake servo pipe. This would explain why my brakes have been real sh**t lately. The engine has also been idling around 9000 instead of a smooth 8000 and its been really p**ing me off. Did a quick fix with some duck tape for now, and the engine runs smoother 8000rpm and the light has gone out
hoooraaahhhhhh! New servo pipe on the way.

Cheers
Alex
