RS4 B7 Intake Manifold Deflap - Mapping issue 6800 RPM
Posted: Wed Mar 27, 2019 9:56 pm
Hi All,
I have been a lurker for a while, but have recently purchased a 2006 B7 RS4.
A few days after purchasing it, the EPC light and engine light came on, and it was found to be the intake manifold runner flaps.
The flaps were then removed using a delete like the JH Motorsport kit from America. A carbon clean was carried out at the same time. As I knew the car would require a remap, a had the precats deleted at the same time. The sensors for the intake manifold were left disconnected at this time.
Obviously, as the car had these items removed, the EPC and engine light were still on when the car went for mapping. This is being done at a local remapping company that I have known for a few years, in conjunction with a well known mapping company modifying the map to suit.
Fault codes at the time it went in were:
P2014 -
P2019
P2008
P0421
P0431
A map was installed, and all lights were removed, however the rev limiter hits at 6800 rpm.
The car was returned to the garage who in conjunction with the mappers have struggled to improve this.
No fault codes are displaying on VCDS.
A smoke test has been carried out on the vacuum system and all vacuum items seem to be working.
I know that they have increased the rev limit but something seems to be stopping it from reaching its max RPM.
Would anyone know what they could be missing/what issue the car might have that is stopping it rev throughout the whole rev range?
