  1. As my post was posted 23 hours ago and it is now 6:45 pm -ish, it means my post was posted about 6:30 -ish last night and not at midnight. Either way, a full day later and not one word of advice, but I was told off so at least I know this thread is live. "Really, no one" was posted 8 hours ago being 10-ish this morning. I do not know how this forum works but I remember my very first post on a car forum asking for help and almost immediately I was chatting to half a dozen guys who 17 years later I am still friends with, I guess forums have changed, or is it the willingness to help others ? - rhetorical .
  2. Really, no one ? Can anyone recommend an Audi specialist in the Cambs area ? or even someone who I could talk to to ask if the problem is in the ECU ? Is this thread even live, can anyone see it ?
  3. Hi guys. This is my first post here, mostly because this is my first Audi problem that I have not been able to cure for probably 20 years. I did search for this problem but I couldn't see any that refers to "cam sensor low voltage", if this has been covered then please guide me to the link. The car is a 2008 A4 2.0 tdi S line. 85,000 miles. The car is difficult to start (almost impossible) unless it is hot then it'll start right away as it should. We did a diagnostic and it shows low voltage to cam sensor, I checked the plug going to the cam sensor lead, this is marked (1) (2) (3). From reading I found the number 1 pin should be 12volts reduced to 5 - 7 volts when running. Number 2 pin is the sensor wire, again this should be 12 volts and between 5 - 7 volts when running. Number 3 pin is Earth. Firstly I would like to know if this is correct as it is kinda important to know. I have between 2 and 3 volts to wires 1 and 2. This is my question. Where do these wires connect to ? if it is the main ECU then it is probably that the ECU is faulty ? Is this a normal / common issue with these cars or is it rare ? if it is common then please tell me the cure. I have a ECU guy that can check and repair, but he is a bit spiteful, so I dont want to just give him the ECU unless it is likely that the ECU is faulty. Please help if you can as the car is now off the road. Many thanks.
