There are several possible reasons why the turbo on your 2002 Golf TDI might not be engaging:

1. Boost pressure issue: The most common cause of a non-engaging turbo is a boost pressure issue. This can be caused by a leak in the intake system, a damaged turbocharger, or a clogged air filter.
2. Malfunctioning wastegate: The wastegate is a component that controls the amount of exhaust gas that flows through the turbocharger. If the wastegate is malfunctioning, it may not allow the turbo to engage properly.
3. Faulty turbocharger control solenoid: The turbocharger control solenoid is responsible for regulating the amount of pressure that goes to the turbocharger. If the solenoid is faulty, it may not be able to control the pressure properly, leading to a non-engaging turbo.
4. Electrical issue: There may be an issue with the electrical components of the turbo system, such as a faulty wiring harness, sensor or control module.

To diagnose the problem, you can check for any visible leaks in the intake system or damage to the turbocharger. You can also check the wastegate for proper function and inspect the turbocharger control solenoid for any signs of damage or failure. If you are unsure how to perform these checks, it is recommended to take your vehicle to a qualified mechanic for a proper diagnosis and repair.

Question edited with a GUESS at the make and model. Question moved to the guessed make and model category. All questions need 'year make model'. You need a good man with a scan tool. Transmission Position Sensor is my guess. It is a known issue. https://www.google.com/search?q=2002+Golf+not+engaging+3rd+and+4th+gear ..

it uses the same resevoir and pump as the front.it will have blown appart probally because you attemted to use it when the jet was frozen...there are 2 places it blows appart in the tailgate where it connects to the motor or in the left corner in the headlining.the the wiper motor itself can also leak .see if you can find a area that is wet either around the tailgate catch or the headlinig, hope this helps cya

Hi, I have a 2001 polo 1.4 mpi it lackes power when you hit a hill it just dies, It has had new cat, fuel filter, fuel pump and throttle body, but is still the same it just dose not want to give me full rev's?

Has the car been serviced recently?
If not I would suggest getting it done.Not sure if you have diesel or petrol, but oil can thicken causing more load on the motor and airfilters get blocked and can cause a rich fuel mixture.

If petrol you can take out the plugs to check if they are a light brown colour, if very dark or black you need to check and adjust carb/injection settings/filter.Need to know what engine it is really.

Try replacing the sensor. They are not usually very expensive. When the engine is COLD! Remove the wire to the sensor and unscrew it. A deep socket will be easiest. The hole will only leak a small amount of oil. Wipe the excess oil out of the hole and fit the new sensor. Turn it until it is tight but DON'T force it. Reconnect the wire and clean away any spilt oil.

Check your distributor timing.

OK.!

Hi.it sound a lot like a ignition coil coils tend to do that if its got a crack it Swell when the temperature rises

May just be the serpentine belt instead of the timing belt

The door lock solenoid for the passenger side is possibly defective, and that is what caused the fuse to blow in the first place. If you apply voltage to the solenoid and it works, then the driver transistor or wiring would be the next place to check. Hope this helps.

Check the coolant sensors. One sensor, when coolant is overheated, cuts the ac off, this sensor may be stuck electrically open, only two wires going to it. Other sensor has four wires, two for temp gage and two for engine management.
