I have a strange problem with my car. I previously had warm start issues that were solved by replacing the crankshaft sensor. Everything has been fine for a few months.
I then had warm start issues again and my garage diagnosed the issues as a stuck throttle (error codes were showing this). I got this replaced with a used unit and the car drives much better and throttle response is very good. Unfortunately this has not solved the warm start issue as the error codes have now changed. If I start the engine when cold I have no issues. If I drive around and let the engine warm up then it will not start and even before I crank the engine the Transmission Failsafe Failure message comes up.
The errors from diagnostics are below:
110 - signal pedal travel sensor
112 - signal throttle sensor potentiometer
169 - Engine throttle output stage shutoff diag
171 - Plausibiilty system engine throttle
115 - Reference voltage 1 pedal travel
021 - Activation VANOS solenoid valve inlet
019 - Activation VANOS solenoid valve exhaust
053 - Activation idle speed control valve opening
027 - Activation idle speed control valve closing
217 - Signal CAN EGS
130 - Signal CAN ACS
068 - Activation solenoid valve
These errors automatically clear themselves after 5-10 minutes and the car will start again with no issues.
The car always starts fine straight away but if I wait for 30 seconds it fails every time. I then need to wait for 5-10 minutes and then the car will start again with no issues. I have no problems with idle or throttle response.
The DME adaptations have been cleared in the throttle.
Does anyone have any ideas on what could be wrong? This is a real pain as I get stranded when getting petrol. My garage thinks it may be the fuel pump?
Thanks.
