so i bought myself a '57 plate 66k A6 Allroad
Drove it 200mile and got a limp mode - no lights on the dash
turned her off - back on again - everything OK
process repeated 30mins later, and the day after and so on for a week.
Then on a longer run to Scotland she didn't reset when turned off and I got an "Engine management" light come on. This stayed on for 2 days... then went out... but then came back 200 mile later. No flashing "Coil" lights.
A Draper ecu reader gadget came up with
Turbo Boost Control Solenoid Circuit Range / Performance.
Went to a garage (non-audi) and he confirmed the Boost Actuator was throwing an error.
We thought we had two options -
- Clean the turbo
- OR Replace the Turbo.
Said garage then spoke to an Audi dealer who suggested the following
- New Turbo
- AND New Exhaust Manifolds
- AND New EGR Bypass.
Audi price - £4500
Their reasoning is apparently that the manifold could be disentegrating and pieces of metal are therefore lodging in the turbo vanes.
I have searched for hours to find any problems / issues with Exhaust Manifolds. Found none.
I did find one post on one forum from a bloke with a similar sounding problem who got advice from Audi Warrington.
uk-audis.net/topic/4637-30-tdi-limp-mode-with-flashing-glow-plug-light-actuator-fault/
Has anyone heard of issues with exhaust manifolds?
I dont doubt there could be problems with sensors or tubes/pipes... but exhaust manifolds???
any pointers gratefully received
thx
