I have lost the key for my vw golf 1999 diesel

I wouldn't suggest it. It wouldn't be just an engine swap that you unplug and unbolt and and then reverse...thats not to say it can't be done with a lot of thinking and work and reprogramming that's usually for vw experts...your better off to keep looking at other wreckers for the exact motor

If you are a diesel use 15w40 or anything approved for diesel.If you are a gasoline engine 10w30 is suitable or 10w40 or even 20w50.

sounds like the immobilizer is kicking in.you may have to go to vw to get it progamed.

Hi Paul, Most of these gearboxes were almost identical for vw during the those years, some manuals are available free from this site

Hope it will help you out.

is this a brand new or used part ....

thats the heater coil symbol for the diesel engines.
does it stay solid at beginning as normal?
if the car drives normal, then maybe its just a loose connection/wire somewhere

petrol or diesel,remove the sump and you will see the oil pump and strainer,remove the four bolts holding the pump and then remove,refit is reverse of removal

Do not attempt to replace Valve guides. You will damnage your cyl. head. Take it to a machine shop and have them do that.

And injectors are to be replaced when they no longer work. Their is no matinance sched. for injector replacement.
