Hello there, I've picked up a 1989 Jaguar XJ6 that was fettled by Janspeed back in the day. The fettling involved fitting 2 turbos onto the side of the engine It's been of the road for the last 9years, but is now road legal and running-although with issues. The main one being a terrible idle when cold. A lot of the standard Jaguar equipment was substituted in this conversion and I suspect the Aux Air Valve fitted by Janpeed has given up the ghost. After some research tonight, I've found that the Bosch valve was fitted onto the Mk1 golf. Does anyone know of any other vehicles this valve was fitted too. I imagine that the mk2 one would also work but I'd like to keep it original.
If you look up the part number on the Bosch website you should be able to find the answer. http://rb-aa.bosch.com/aa-uk/en/products/start/index.htm
the mk1 1.6 and 1.8 AAV are different, but the 18 mk1 unit is same as mk2 1.8 if it helps 1.6 is 049133453c and 1.8 is 027133453
