A6 C5 2.5TDi No power and White Smoke
Hi and help
Just bought above car and plugged in VAG com.
6 Pcodes present
All appear to point to wiring.
Also Noticed that coolant temp was low at 41 deg and gauge showing 90 deg.
All terminals on coolant sensor were corroded and full of water, Have swapped it and now seems to read senseable values. Power seems to have improved but still white smoke.
Appear to be lacking in boost, if you flor the throttle there is a big flat spot at 3250rpm
Will investigate further to any loose fitting turbo hoses and will check MAF sensor
Think the engine is ABF.
When sorted how do I get more power?
At a sensable cost.
Please help and thanks for looking
White Smoke= Unburnt Diesel
White smoke emmitted from the exhaust is more common to being unburnt Fuel,But could be confussed with water leaking into the combustion chamber and exits as steam, usual tell tale sign could be bubbles and excessive pressure in the header tank
Black smoke is excessively overrich fuelling and burnt, hence the soot,BURNT PRODUCT.
Hope this will clear up some questions regarding the type os smoke emmitted via the exhaust.
