Hi all, thanks for your help with all my other Touareg issues. I am nearly there now with getting it in good order. Here is my latest query.

I keep getting the engine management light coming on and when read with a generic code reader pulls up the code p0016. Now i have tried to read past problems and assumed the worse that it was the cam chain although there is no tell tale signs of chain stretch and the engine sounds quite as a mouse. I have changed the upper tensioner for a new VW item but the problem still persists with the light. There is no noise from the engine etc etc assosiated with stretch. The light only ever comes on when you start the car within the first 3-4 seconds. It sometimes turns itself off too. It never comes on while the vehicle is being driven. If i erase the code it might not come on for 3 days.

Anyone had anything similar?

thanks again

Pull and clean your camshaft position sensors. If you had a stretched chain you would hear it plus getting a code 018 and 0346. Sometimes the halls magnet that is part of the sensor gets dirty and does not send correct signals to ECM. The sensors are on the back of the block on the top. Held in place by one bolt. One for each cylinder bank.

Sorry previous message was for V6. Not certain if the V8 has two camshaft sensors. In any event comment still applies clean or replace the sensor or sensors. Cleaning will usually fix intermittent errors but sometimes the electronics are intermittent so better to replace.
