My 2005 Audi A4 tdi started playing up the other day with intermittent power
loss black smoke from exhaust, sometimes grey, and kangerooing is the best way
to describe how it drove with no power around 2-3000rpm. Sometimes the
stability control lights up and wont respond to the switch? The MAF and
MAP sensors have both been replaced but the problem remains. I have cleaned
the dirty EGR valve and performed an ECU reset. Leads to suspect are a water
build up in the battery plenum, unblocked drains and checked ECU out for water
, ingress but all looks good. I am desperate anyone got any ideas?

You can try sticking a bag of silica gel on top of the ECU to dry it out,

but there's probably water in the connectors. Have you tried scanning it
with VCDS/VAG-COM?

This. A generic scanner may not find everything.

under the brake servo, another under the battery-battery removal required to
clear.

Thanks for replying but I have now fixed it myself by fitting a blanking plate

that smart electronic stuff you would think it would recognise a true fault

licenced version. Well within the reach of a garage, and it will run on
a cheap laptop.

As for manuals, ELSAWIN is commonly available on Ebay, or use the
official ErWin manuals.
