    Hi everyone I've read lots of posts on this all seem to have same problem when left for a long period of time 4hrs etc car struggles to start it turns over fine but it like its not catching I let glow plug light go out then turn if I put glow plugs on a couple of times it's a little better not much but it always starts second turn ?<br />
    After reading other posts seems it could be <br />
    1 thermostat <br />
    2 temp sensor<br />
    3 maf<br />
    4 glow plugs<br />
    5 pump timing <br />
    <br />
    I'm going to replace temp sensor first as its cheapest and easiest could someone please post a picture of exact location <br />
    Car is a 2002 A6 2.5 tdi<br />
    Thanks<br />
