[jamesey]

hi ive got round to doing a scan on vagcom instead of my little orange scanner and its come up with loads of faults ive cleared them all but 2 come back...... ive got
00819 high pressure sensor G65 07-00 signal too low &
01134 alarm horn H12 49-00 no communication? where is the alarm horn located on a b6? cheers

Does your Aircon work? If so, don't worry about the G65, it's the sensor on the front condenser.

The siren is in the boot, on the offside behind the amp.

no my air con doesnt work the econ light stays on , also would new batterys sort my problem out? is it easy to get to? cheers

It's fairly easy to get to, remove the boot hooks, remove the offside trim, remove the amp, and then siren is in there. The only weak link tends to be the batteries, but obviously I can't say whether they will cure your problem.

AC sounds like a dodgy pressure sensor then.
