Hi, I had a rough start on my Octavia MK1 with ASV engine, tried couple of things but not helped. Once accidentally lose my brake fluid from master cylinder. Resolve the problem and remove the air from master cylinder removed the EGR. It was full of dirt AND the valve was blocked. In that time I helped to somebody to repair a broken water pipe with same engine. Indeed the guy looked after my Octi and said my vacuum pump leaking the oil and not make enough vacuum to start my blocked valve. I cleaned the vacuum pump and bonded with 2 component metal bond on the top where the oil leaked saved about 200 Euro. Cleaned the EGR and air intake manifold and NOW she is starting when turning the key, problem solved.

hi folks just share my experiencies, had a problem with cold start, changed glow plugs (originals was good, I saved them) checked the wiring to glow plugs, positive poles form battery and fuses and the relay 103. The original with number103 was bad, bought a cheap one, what I checked and worked good when I checked, BUT the problem not solved. Under 10 Celsius rough cold start, at 11 Celsius everything OK. I lost. Used a year with this issue this winter and changed the starter, but it was a bad idea, it was a weak cheap french and rebuild the rebuilded bosch with my friend and took it back. Cold start not changed. Somwhere on VW forum I red, the cheap relay not working properly, so I bought a Beru GR081. Indeed changed the cambelt, waterpump and the coolant too. When i changed the relay problem solved. I was very happy. So my opinion need a good relay like bosch or beru and need to change the coolant too. I think with old coolant the CTS cant send a proper signal to the computer, what is very sensitive for weak resistant. I had an issue with coolant level sensor, cleaned inside the bottle a very thin copper stick and the problem dissapeared. I had before an A3 with abs problem (change the abs cube to used 500 british pound) but when I cleaned the fuses on the top of battery problem solved. So the resistance is very important. I hope can help to anyone
