check the ecu and fuel relays....common issue

[DOC_2]

cheers mate i will try that, do you know what number is on the relays please?

faulty ecu relay no 30
Both the 8v and 16v have the same #30 ECU   The #30 relay part # is 165 906 381
Check them by feeling how hot they are after 15 minutes of driving. they should be warm to touch. so cold relays means faulty relays!

faulty fuel pump relay no167 
Make sure you get a light grey/brown coloured one with 'made in germany' on it and it comes brand new in a vag box. The originals were made in Tunisia and are a known issue!! and test is same as the ecu relay

and there's a fusebox guide in the maintenence section up top
