Title: Audi Rs4 boost problems
Post by: Jesper Rs4 on August 23, 2014, 04:10:42 AM
Hi,
I have a problem with my RS4, usually boosts exact 20psi, but has started only boost 16-17 psi and periodically 20-22 psi but only for short time, I have changed the following:

6x ignition coils
6x spark plugs,
DV's,
MAP sensor,
MAF sensor,
N75,
Tuned by a Danish tuner, i have Wagner DP´s and has not failed the last three years.

Before the new Coils i had misfire logged in ecu, i couldnt feel anything, after changing them i have no errors logged.

Any ideas?

You should probably log actual boost at some point.

I would be concerned with those timing corrections.
