DISGUSTING noise after engine off HELP!

[HyperXChaz]

Appreciate this is my Uncles 2.0tdi Audi TT. But it's a CUNA engine and looking for some advise / thoughts?

To me it sounds like the starter motor is engaging over and over / some type of electronic coil whine and trying to activate something.


A few weeks ago he had it at Darkside - it's now 260bhp with all the necessary mods / turbo upgrade etc- I'll say no more.

Any advice?

Just for anyone interested - It turns out there was a 2nd water / cooling pump which Darkside had disconnected but left powered so it was going absolutely off it's tits and ended up throwing an eml when fully removed. They're going to map it out
