Question HELP!! A3 2.0L FSI Warm/Hot Start Problem

Hi everyone,

I've bought a 2004 Audi A3 2.0L FSI and it has a problem when starting from warm/hot.

It starts first time from cold but when I've driven it and stopped then tried to start it again within 1 to 2 hours it takes a good 3 or 4 goes to start!

It turns over but just doesn't fire up!

I was advised to change the Engine Coolant Temp Sender which I did but this hasn't cured it..

Does anyone have any suggestions as to what this could be??

My next change I think is going to be the Camshaft Speed Sensor..

Please help!!

Cheers,

Sam

engine speed sensor is fried , coolant temp sensor is when the starter turns but doesnt engage, bosch is a retarded *** company that makes shitty electronics, get a new engine speed sensor, it goes into the bell housing, happens on alot of the audi's they overheat because bosch is incapable of building a proper sensor and the insulation is too thin to protect the sensor...

i have a very similar issue on my 3.0 A4.. dealer had it for a week and couldnt figure it out! ill have to look into that engine speed sensor though, havent heard that one yet.. i was thinking fuel injectors leaking fuel into the cylinders while it sits

Default Fixed!

I did manage to fix it!

Turns out there was a lot wrong under the hood.. Needed a new cam belt as the oil seal was fitted incorrectly causing oil to leak over the belt leaving the engine dry..

At the same time they changed the crankshaft speed sensor which did the trick and now it starts first time every time!
