After a few journeys if I switch the car off and then try to start then it just does 2 of the following
1 The engine keeps trying to start. Inside the car it says engine starting but it doesn't start.
2. The car starts but dies in like a second or so.
I have to leave the car overnight and the next day it will start perfectly fine.
The car is a 3.0 VW Phaeton. Diesel 2008 model. 75k miles on the clock.
The local mechanic thinks it's the imobaliser or throttle body. I don't have the obd codes
Any help would be appreciated.
Clean the throttle body with spray cleaner and scan the vehicle for any codes.
When the car does not start, try this: Press the gas pedal all way down and start the car and see what happens.
