Hi,

I bought a 06 Passat Estate 2.0. The day after I got it home it wouldn't start, then on the 3rd try it started. Now this is a common theme and doesnt seem to matter if its cold or warm, although always seems to start first time in the morning after being left over night. I can nip to the shop 5 min drive run in and out and it wont start. If i pull the key and leave it approx a minute it'll fire on the 2nd/3rd try.

I thought it maybe the battery but it look relatively new with clean terminals. Checking with a multi-meter I get 12.7 with the ignition on and 12.4 with the engine running. A friend has attached a VAG-COM and here is the following report.
