1.4 diesel engine cold start cracking, popping, knocking, vibration

My polo 6 clp engine I changed spark plugs, injectors, coil pack and new throttle body and it still misfiring and acceleration paddle not working what could be the course?

Engine turns over but doesn't start. Turn off ignition and try again and it starts.

Car won’t start — key turns, lights on, but no engine sound. Likely due to faulty starter motor, relay, or ignition switch.

Today was the first time it happened. I was approx. 5°C out in the morning (a lot warmer now that its spring) and I needed to start the car, like usual. Once the starter got cranking, the engine started to vibrate the entire vehicle like crazy. I stopped, checked for any loose, broken or foreign parts and dried again. Same result.
Since I was desperate, I tried a third time, but this time with some extra gas, and the vibration stopped. It did not return for the entire day ~40 miles, after 20 miles it got turned off and cooled down. But it wasn't so cold on this startup, as the sun was blasting the car

Do I need to be concerned? Starter issues? Some sensors messing with the idle? Engine mounts broken, even tho it only vibrated for less than a second?

Car died while I was trying to drive it into the garage... Had the engine redone but I'm not getting any pulse power from the ignition coil. Swapped the computer box

The car switches off when you take out the jumping cables and doesn't start on its own

Cranking but engine not starting

Car was working perfectly. Stopped at Friends for 30 Minutes. Car does not start now. (The Engine Cranks. Hooter and Wipers work. Indicators do not Work)

My car cranks but not starting I don’t know what’s the problem with it

Hi i have a Polo tdi 1.9 2006 model.
The car is not cranking or starting so i thought it was the alternator or starter or battery to i replaced all brand new but stil it wont start. When i turn the ignition key the lights on the dash comes on but when i turn it to start then it doesnt even crank but i do hear a faint clicking sound so not sure what might be the problem. Im not sure if its the relay fuse or what it might be

It doesn't start at sometime

I turn the ignition but it doesn't fire...had the top done... Was told I need to sort my cold start out... And get it to an auto electrician... And change my plugs... It ran yesterday... No problem start and go...

Doesn't want to start only starts after 30min

The car overheats and the cooling water boils after driving for some distance .I have tried changing the cooling fan sensor but its not working.the fan is not starting automatically please help

The car doesn't have spark or compression it does not have power an not starting only cranking but not starting... I need help please

Hi there

I got a problem with my polo 2014 1.4TDi. When engine cold starts and drives perfect. When getting warm then flashing spring is coming out and engine looses power and not exceeding 2000rpm. When switch the engine off and on all back to normal then after driving a while problem appears again.

When i turn the key dashboard light but car doesnt crank.

When I drive or after a small trip. Then it won't start again. When I try it

EPC sign. When diagnosed; it shows irregular misfire on the engine. I have changed the spark plugs along with the coil pack. But still shows sometimes when I'm driving. I therefore have to restart the vehicle & it goes away. I'm not sure as to what triggers the EPC sign that makes the vehicle to drive slow with less power

Car cranks but won't start I've changed crankshaft position sensor and camshaft position sensor, new fuel pump and bought a new battery as well

I had a epc and check engine indicator
Then i went to the mechanic mode i cleaned the throttle body by my self using throttle body cleaning then fixed the EPC light now disappeared but I noticed while scanning misfire is happening so one cylinder was not able to produce power only other 2 cylinders were produce power so i changed 3 spark plugs not a single piece i changed 3 spark plugs in NGK brand but the problem is still there then i have changed 3 ignition coils in same NGK still the problem is there what can i do... I forgot to said its 3 cylinder polo

The car won't start when I'm pressing my foot on the clutch peddle to start

Hi,my car doesn't start its a vw polo 1.9 tdi,on crank sensor connect there is no power and signal and on camshaft sensor no signal
. Its only cranks for 2 seconds and switch off
