The engine has all the appearances of an AAZ engine mechanical clutch, cold start assist, valve cover, no intercooler and short 90 deg elbow direct from turbo to intake. The tag on the fuel tank inspection plate indicates AAZ and the print out i got from VW indicates AAZ. This print out also indicates no airbag, which was still an option.
I do have a glowplug indicator which works on startup in the morning although it does not come on when the ambient temp is above 5 deg C.
The engines idles at about 1100 RPM till warmed up then slows to about 950.
There is no EGR valve which is absent on some of the AAZ engines.
The only emblem on the steering wheel is a horn, it does not say airbag or SRS and the shape is different from airbag equipped cars.
This is a very basic car, hand crank windows and no key lock on the passenger door.
For all of these reasons I believe the faulty solder joints are the problem.
My cluster does have black face dials and other than the intermittant indicator lights works fine, my question was will the tach in a cluster off a gas engine which has white face work on my diesel.
