Slow T, White Smoke And Error Codes 19463 17571

[DaveJH]

Galaxy 2005 TDi 150bhp 1200k miles.    Runs well (at present),  uses no oil.  Good mpg.

 

On cold start seems to fire on one cylinder only before others reluctantly start up.  Good size cloud of while smoke tinged with blue which dissipates as engine starts up, some white smoke until warmed up. 

 

Otherwise fine except good cloud of muck when accelerating hard in lower gears, such as joining motorway.

 

First thoughts were faulty glow plugs, and possibly dirty injectors, so purchased a low cost (Memoscan u281 for VAG group vehicles ) received and used today

 

Two engine error codes shown:

 

19463  01/02     which google search shows as Camshaft Position Sensor

17571  02/02     which google search shows as Fuel Temperature Sensor

 

My query is - are these likely to account for the symptoms 

 

If so, which to fix first based on being easier/more likely to fix the problem.

 

Also, is either of there faults serious in the sense of requiring urgent attention.

 

Any advice welcome

Give it a run and plug it in again. If both codes come back up then replace both the sensors. Another posibility is that the timing is out. That would account for the rough running and the face the cam sensor in not in sync with the crank sensor.

Yep clear the codes and go for a drive then recheck as disconnecting these sensors with engine running would register a fault.

Are you due a cam belt change as this would be my first port of call.

inchley, chrispb

 

Thanks for your relies - will do - as soon as I get the car back from trip to south of England.

 

Also thanks for your reminder that cam belt due for replacement at the 120k interval which is coming up.  Seems sensible to accelerate the service and get the sensors and cam belt sorted in one go.

 

Regards

 

DaveJH.
