OK - some plain english - to-the-point advice for engine starts - for ALL engines - hot or cold - petrol or diesel.
- Do NOT touch the throttle pedal at all - don't even fart near it - untill the engine has started and running under its own steam (unless the owners manual specifically states otherwise)
- when putting in the ignition key, turn it to the "ignition on" position, but do NOT immediately activate the starter motor. Wait about 5 seconds, until all the usual warning lights have extinguished. During this phase, the electronic throttle valve self calibrates (and feeds back status info to the ECU). If you touch the throttle pedal - it just messes this up, and confuses the ECU
- Then twist the ignition key - and HOLD it on the starter UNTIL the engine has fired and running under its own steam. It is perfectly safe to hold the key on the starter for upto 10 continuous seconds. If it don't start, turn the ignition fully off, turn on, and wait another 10 seconds before engaging the starter and trying again. Still keep your Doc Martins off the throttle pedal
- After you have released the starter motor, try to let the engine idle for at least 30 seconds, and then you can press the loud pedal to your hearts content
Further info for the GTI, and all FSI and direct injection petrol engines:
Because the high pressure fuel system in these engines is only developed from the engine-driven pump - then these engines have to be physically turned by the starter motor, to build up the pressure in the fuel rail. This means that the GTI (and associated FSI/TSI) engines seem to take slightly longer than normal engines to start. This is perfectly normal, and is not a problem. Just make sure you hold the key on the starter for slightly longer than you may be used to, as described in the above bullet points.
If the Mods/Admins want to sticky this, or move it to a separate post, then that is fine by me.
