Hard Starts

[BEETLE BUG 99]

I have been having problems with my Beetle being hard to start when it is warm.It starts OK when it is cold although, it seems to crank a little more than it has in the past.The warm starts concern me because it cranks quite a bit before starting.Any thoughts?

This is the photo section, not a technical forum but I'll point you in the right direction...

There is a known hot start problem with 98-99.5 A4 TDIs. Pull the connection to the coolant temp sensor and start the car while it's hot. If it fires right up you have this problem (this test will probably cause a check engine light).

There are a couple of solutions - most popular is getting a good tune. The tuners change the fuel maps to start injecting fuel below 250RPMs when the car is warm (70 degrees, I think). The other, cheaper solution is the hammond mod. It's a switch or relay that opens the temp sensor connection. I wired a switch up on the dash and it makes a big difference. Do some searching on here for the directions.

Also make sure your battery is good and connections are clean. If something is preventing the engine from turning over fast enough, fuel will not be injected.

I have been suffering with hard starts in warm weather. The engin is cold from sitting all night or a long time. I must crank several times and for a long duration.
If the weather is very cold, it starts right up. I'll try disconnecting the temp sensor.
