By the way, what's the power output of this engine? Is it a strangled ABF
Golf 16V engine? Or is it an 8V?

ABT is a strangled 8V, 90PS.

Well it did turn out to be the lambda probe. Went for MoT yesterday and it
failed on high emissions (0.5). The lambda passed but garage man said it was
sluggish. New probe fitted and emissions passed & the car is running loads
better with now plenty of pull at top end. Previously if you tried to hold
the revs at a fast idle it would pulsate down & up slightly but now it holds
steady.

Might benefit someone else but another useful piece of info I came across
regarding the Audi VW digifant motors is a common problem with a dry solder
joint in the ecu voltage supply relay (located under the steering wheel dash
(part No. 165906381 & about £10 from main dealers). This causes misfires or
cutting out problems. I read if the relay is black it's the unreliable one
made in Malaysia (or somewhere) and best to change it for the more reliable
bosch light grey colour relay.
