I have the 4.2 tdi mine takes 10 mins or so to get up to temp , just looking back over the posts , you say they car behaves with the air masses disconnected , this tells me it's not air ingress to the fuel or the bypass circuit re circulating any air in the fuel .
The temp sensor could cause this like others have said , it's cheap enough to do to rule out , the fault code for rich mixture .....I would say the lamdas are working and reporting the exhaust condition . Now what would make a rich condition in a diesel ..... so rich is either to much fuel delivered or not enough air , or that the egrs are not flowing the gases which your codes were reporting and the lamda code was backing this up .... egr flow makes rich condition, egr no flow makes a lean condition . You know back there were I said blank the egrs that's what you need to do now or just diss connect them so they cannot work , if one bank is getting flow and the other bank is not it will Cause an imbalance between the banks I'm not getting at you here more generalising , I see this everyday at work folk fitting parts off the back of fault codes or ' guess a part ' they will spend hundreds on parts and not fix it then come to us an moan at the £52 an hour we charge but I will fix it .... just a vac pipe split or summat daft Customer .....£52 for a split pipe !!!! Me " well you have spent hundreds and not fixed it so £52 is a bargain " Yadder , yadder Back to the plot .... blank or diss connect the egrs then see how it goes , one bit at a time .... carry out tests ......rule out ...... move to next test Last edited by Mechcanico Lee; 28th November 2015 at 03:24 PM. |

The one for the 3.0tdi is in a coolant pipe at the back on the left (drivers) cylinder bank.
Just for reference, you never know it might be in the same place.

I would get a dealer one to be honest , you know it will be right and the correct temp range and so on

Intrigued that they are only the 2-pin design whereas D2 (and I though most of the VAG range) used the 4-pin model which is (now) green.
