I have a 2011 transporter, got the moo sound maybe two or three times over the last month. Worried now!!

This is what I have just been quoted from Bill Buckle in Brookvale.

part numbers related to my VIN but should be the same as most T5.1 vans.

See attached schematic.

1K0906627A Pressure converter, EGR GO 0 CO8E27 $141.50 Number 25
7E0129458B Hose vacuum $106.50 Number 21
7E0129458F Hose Vacuum $223.00 Number 20
7E0129458A Hose Vacuum $62.00 Number 32


I intend to check each hose if I can to try and identify which one or the valve is at fault. I'm getting the moo after engine shutdown.

I have had the MOO for the last few years on shut down, apart from the small cow under my bonnet which sometimes needs an explanation to new passengers, we live in harmony with no other issues.

I've had the MOO for a year, intermittently, just shortly after taking off at traffic lights. Never at shutdown. Around 50 times approximately. Only once has it caused limp mode (confirmed with VAGcom) otherwise it doesn't seem to be a significant issue. Fingers crossed.

Haha! It does sound like there is a cow in your car!

Why have you never had it fixed under warranty?

Changed the valve out, $150.00 easy to do, no moo for over a week now.

Hi Zebt, did you change part 25? Or can you let me know what to ask for so I can have a go. Thanks
