Not sure about the engine one one but the others, ive had the alarm DTC when i left my window down once and the alarm was triggered by something, the central locking pump might have a pipe leaking on one of the door locks or the boot lock? i think door panels off and boot trim to check tho, do the doorlocks always come up when you unlock?

alarm and cv pump ignore.
Secondary air system is the warm up system it has a leaky pipe I would think.
Shouldn't be to difficult to get it checked out.

Thanks folks. I'll reset them and have a look at the intake system.

Hi David, there is a valve for the secondary air on the side of the head. It has a large flat top with a tiny hole in the centre. When starting from cold wait for the air pump to start then put your finger over the hole, if the diaphragm is split, you will hear a change in noise as the valve now lifts from its seat introducing the air.
I am aware of a TT having most parts inc solenoid valve and hoses being replaced with the light still coming on sporadically. The fault was eventually traced to this combination valve. This is the easiest way to test it quickly. It is a sod to change on an ARY 180, not sure on a BAM 225.

If this fault flagged on an old V6 2.4/6/8 or V8 4.2, it always seems to be the vac hose split or cracked due to heat from the proximity of the exhaust manifolds. They go right where the hose joins the combi valve.

Interior monitoring simply shows the system was triggered from inside sensors. (you can turn off or use adaption ch 1 to reduce sensitivity). Or close windows.

Pump system has leak for other code. The pumps get very hot even with the cutout when leaks occur.
