If the fuel pump check valve check valve is bad, the car may be unable to start. If the car does not start, turning the key so that it is one click away from starting, then repeating this process several times, may build up enough pressure so that the vehicle starts. If that is the case, the check valve is bad and needs to be replaced. check the fuel pressure regulater also. good-day ! If fuel pressure is low, disconnect the vacuum hose to the regulator. You should see an increase in pressure, if the regulator is not leaking. No change would indicate a bad regulator, check this first and get a fuel pressure reading on it to determine the pressure.

Open the hood, its under the intake manifold and coolant tank.

ASR - Acceleration Skid Control system. When ASR warning light blinking the system is activated itself for car acceleration skid control. For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing. ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning. The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster. The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

It's very simply to find out if the turbocharger is causing white smoke from the exhaust vs a blown head gasket. So, remove the turbocharger's compressor inlet centre hose (from the aluminium side of the turbo). Then see if there's in plenty of oil coming out from the hose and from the turbo. I'm 100% convinced that the turbocharger is damaged in your case. You can remove also the exhaust pipe out from the turbocharger, and see if there's a lot of oil coming out. Repair or replace bad turbocharger with a new one (or with a second hand in good condition one). Good Luck!

You can look for Haynes Repair Manual for your car, they are mostly sold on any auto repair shops or auto zones, or order it online. I'm not sure if you can find any pdf format of it though. Hope this helps

Check & replace if necessary the brake pedal switch placed above pedals on the support.
If the problem still occurs you might access the ABS & ESP ECU (Electronic Control Unit) using diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored.
Then you will be able to replace bad piece(s) and fix the problem by erasing all DTC stocked inside ABS ECU & reset it.

The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: brake pedal switch, front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.
I'm convinced that your brake pedal switch is faulty because the glow plug warning sign went ON after ESP warning light. Just replace the brake pedal switch, see if rear stop lamps light when press the brake pedal, and test the car on the road.
Good Luck!
