Hi guys,

I have a Polo 1.9 TDI Sportline(96kw) and I recently did the engine on it. Since then , the car has a starting problem.
When I try to start the car, the engine just swings and sometimes it will start the car but most of the time, I spray a little quick start in the throttle to get the car started.

I had the timing double checked, changed the cam sensor, crank sensor, another mechanic advised that one of the injectors was reading low, replaced the injector, since then the slight miss cleared.

When the car is in motion, it goes well however it sometimes has no power when trying to take off and sometimes switches even switches off, the car also throws out some black smoke when accelerating.

I plugged in a Diagnostic machine and it hasn't picked up any faults.

Any suggestions guys?

This is a new forum layout with loads of bugs which have been reported in the new thread. There is no TDI Wiki at the moment or original similes. It doesn't show the car spec/location.

This has been talked about many times.

I've made a pole which no one has posted in, there are a few votes and comments.

Do you like the new forum features?

Wiki pages have been restored as of 7th December, I asked where is the link it should be on top of the main forum.

Which diagnostic machine?

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.
