    1. Replace glow plug
    2. Replace glow plug (might as well replace all four)
    3. Check your EGR valve. It may be plugged with carbon & oil. If so, it needs to be cleaned.
    4. N75 valve may need replacement, or you have a vacuum leak (one or more of the hoses may be cracked, also check the brake booster hose for cracks).
