[T3] Fastback Engine Issue

[Jim Adney]

Anything is possible, but this seems unlikely if your condensor was a Bosch 
condensor. For the record, I've never seen nor heard of a Bosch condensor 
that had failed. All my cars have old, original Bosch condensors running in 
them.

I can't say the same for modern condensors sold by Bosch. I've seen a 
number of them that were gold colored and appear to have been made by 
someone else and packaged in a Bosch box. The old OE Bosch condensors 
were silver colored and had the Bosch logo and 10-digit part number 
stamped on the end.

Nevertheless, I hope you've found and fixed your problem.
