Hot start issues with Codes P2177 and P2179 - FIXED

FIXED SEE LAST POST. Faulty Hengst fuel filter.

Hi Guys,

I've been battling a hot start issue with codes P2177 and P2179.

When the car is cold it starts fine. Once it is hot, the car just cranks and cranks with no start. I then turn the key off for a few seconds, try again and it will crank for about 5 seconds, then fires up. Idles a little low for a few seconds and then starts to idle fine.

I've replaced the fuel pump, fuel pump relay, fuel filter, cleaned the MAF and the throttle body this past week. Can't see any obvious vacuum leaks. Hose and clamps for the MAF look prefect. Still have the problem. Any other suggestions?

Thanks!
