VW Caddy 1.4 AUD 2003 - Intermittent misfire, codes 16684, 16685, 16688, 16804 - Fixed #

Year of Manufacture *: 2003
Engine Size and Code *: 1.4 AUD
( Optional ) ECU Type: Bosch me 7.5.10
( Optional ) Scanner Used: Sykes G2 and eobd C Reader

Hi ,
This vehicle has a very intermittent severe misfire.
With the Sykes G2 scanner I got :
16684 intermittent misfire
16685 intermittent misfire cyl 1
16688 intermittent misfire cyl 4
16804 catalytic converter.
from the above I suspect a coil problem, but and now for the strange thing, it will not run with the scanner connected? I was hoping to watch live data!
It also wont run with the eobd C Reader attached?
The only code shown on eobd is P 0300 for int misfire.
Any thoughts, is it possible coil drivers in ecu?
regards
Mike

Hi Mark
thanks for the quick reply;
I would do if I could be with the car when it happens! went on about a 20 mile test with the customer no problem at all!
I am mobile so its tricky, I ordering a coil as I think its worth it, still cant understand it not running for a live data check?
one thing although I cant see the relevence its first registered in Norway?

cheers
Mike
