What's up with my D4???

[Bill]

Restricted power and then an engine warning light. I have an IID2 so engine error codes...



Symptoms are a whistle that sounds a bit like a police siren when I lift off the throttle under load...

I'm guessing (/hoping) it's just an induction leak, but haven't managed to isolate it while parked.

I had P006A coming up which was the seal at the top of page 9 but it may help with other things for you to check.

Brilliant, thanks. It's sod's law I'm on holiday at the moment!
