Hot starting saga continued
Regarding my earlier problems of hot starting my WR engined UR-q
I removed the cold start power supply, and I can't comprehensively
say that I tested the hot starting ability, but it did start easily
when the engine was warm. However warm starting was not a problem;
it was always attributed to starting with a high under bonnet temp
following a 'good thrash'.
Sunday AM - Would not start at all. Replaced cold start and fired on
twist of key.
Noticed that the injector fan was not running, when the engine was
hot. Put a switch under the bonnet as a temporary measure to test
Thrashed the living daylights off it, with the inj fan running,
parked up, left for ten minutes and returned. Fired first time.
I know that is not a conclusive test - but its a good bet that it
wouldn't have started without the fan cooling the injectors.
Next saturday will be a good test, after a blast around a sprint
track, courtesy of Club Audi (UK)......sorry Phil - will still be
Does anyone know how the injector fan should be invoked ?
I take it that the probe by the injectors is a temperature sender,
how can I test whether this is broken ?
Skint, but strangely happy....
