Can't 'blip' the throttle - revs stay 'high' for a second or two before dropping...
As above, had a slight problem the other day when the turbo didn't 'come on'. It seems fine now - I put it down to a 'sticky' variable vane turbo actuator rod which i've unstuck.
The problem i think I have now is this - when I 'blip' the throttle, the revs stay high (i.e. at the top of the 'blip') for a second or two before coming down - it does this whatever the engine temperature - whether cold or running temperature.
Is this normal? The car is a 1.9TDi SE with the 85kw / 115hp engine.
Any help greatfully received as always.
Last week had the codes read as follows:
19464 Cam Position Sensor G-40: Not Plausible Signal (I put this down to it being disconnected and reconnected during cambelt change 10K miles ago)
17664 Coolant Temp Sensor G-62 Open / Shut (I've noticed an occasional lack of temerature gauge reading - now it seems to want to stay at 80C and not go anywhere near 90C on the gauge!)
17965 Turbo Pressure COntrol Limit Exceeded P1557 (this is what caused the lack of turbo last week).
Another little 'niggle'...
Ok, car seems much better with this revving and throttle blip situation though not cured. So going to change the Coolant Temperature Sender to see if that makes a diference.
Popped down to local VAG dealer and they offered me a choice of 2 diferent sensors - both green, one a 'square' shaped plug, and the other a 'arch window' shape plug. Couldn't for the life of me work out which it was without taking some air hoses off, so will check tonight and get the right one.
Ok - here's the niggle.
I worked out how to display the engine coolant temperature via the Climate Control panel, and once engine is warmed up it shows a steady 90C with no deviation. Thing is, the tem gauge on the dash will vary between 60 and 85 with a mind of it's own.
Does this deviation (90C on the Climate Control display and 60-85C on the gauge) point to a CTS problem or something else?
