camshafts timing marks Finding TDC and Timing for New Reluctor Ring?

[Corbin97]

Hi there, 

Iv had a problem where my engine kept cutting out whilst driving and had difficulty starting, i got the code P0727 (engine speed input - circuit no signal) and I replaced the crankshaft speed sensor (genuine VAG sensor). Whilst the problem still wasn't fixed, it did improve however it took over 10 seconds to start. I then read the raw data from that sensor with an oscilloscope and there was no recognisable pattern which led me to take out the gearbox and to replace the reluctor ring. I am at the stage where I need to find TDC on cylinder 1 to install the new ring but I cannot find any timing marks on the cam pully or anywhere else... 

Any help would be much appreciated and my engine code is BKC. 

 

thanks in advance,

Corbin
