Somebody help me please.
My old Passat B6 2.0 BKP TDI have a hot start problem from few weeks ago.
It has original ECU bin.
How can I solve it?

Best regards, Tibor

I don't think PPD has a hot start problem, what are the DTC in the ECU?

I checked it VCDS, but the engine hasn't fault code.
But when I went a 20-30km, after stop and 10 minutes later I try restarting the engine, not started it easy.
I'm thinking if I get more fuel in starting rpm, I think it will start more lighter.

Checksum, typically, the device calculates them when saving the file. Check if your tool does this.

You can first unplug the fluid temperature sensor and see if the car starts well. 

Try this without pass, no cks

Where can I found "fluid temperature sensor"? Is it a liquid clooling system's sensor on the cooler, front of car, under bumper?

Thanks, hudakmuvek

Dear Friend ,
I tested it booth of modified ECU's program.
Your program solved my hot start problem, because, when I try to start the car, the ECU allow to give more fuel on low rpm, finally, the engine easy start again.
Many thanks
