I've had a niggling problem with my 1.7 TD.. I think it may be temeperature related..
If I can ask all you 1.7 td owners...
- What temperature does your water gauge show?
- once it gets to operating temperature does it always stay where it is regardless of fast/slow driving or heater controls?
- When you first start the car do you half power when cold, or do you get full power straight away?
My problem is that I get half power (specifically very little below 2.5k) and it rarely comes on full power - only when it's warm and I can find a big hill where I can leave my foot down for some time.
I was thinking that the engine may not be getting to temperature; not enough to come off the ecu's cold map.. I replaced the thermostat today and it rises faster to 85 degrees but no higher; in experience it needs prolonged heavy load to come on full power and it only happens at around 87 degrees. The thermostat removed was rated to 89 degrees.
I wonder if all the other 1.7 tds are showing 90 degrees on normal use...? if so, my sensor may be out.
does anyone know if these ecu's have a cold map?
