Zafira code
« on: 25 October 2014, 14:05:18 »
Just picked up an 02 zafira with low miles 1.6 petrol, gonna scan it when the battery is charged as EML is lit and has been for years apparently " the garage could never find out what the cause was"

Any predictions?   Free broken corsa wiper blade from Opti's lean to consevatory to anyone who guesses the cause. ;) ;D

1.6 petrol manual, I too would go with EGR

(just for the fun, no recommendations without reading codes ;).  EGR can be switched off on those (but not autos).

There were a few 1.6 8v ECU's which didn't accept the EGR delete, most were fine. (That's both Auto and Manual)

As this is a 2002 Zafira, I'm guessing it will be the 16v model, in which case, ALL are happy with the EGR delete.

Does EGR delete just mean blank it off or does it need doing via ECU ?

If its that piece of shit, I would be very cautious using it for any programming. I've not specifically heard of any issues with it doing that specific function, but we do know that it is an ECU destroyer as soon as you use programming.

 ;D I knew you'd bite. Should be a simple change to "egr not present" I expect, not had any issues programming with it, on my own cars obviously.

Battery being off has deleted the code so no winner yet !

If you're gonna program with that heap of shite, do yourself a favour and buy the genuine one from the UK importer. Then you will:

a) get the proper hardware/firmware of the reverse engineered device, rather than some useless Chinky attempt at reverse engineering the reverse engineered device.
b) have some backup/support for it
c) have a possible avenue when it does bugger up an ECU (it will...  ...or certainly the clone ones will)
