Title: Help with zafira warning light
Post by: lee4206 on 21 September 2010, 22:57:02
A friend has a 2000 2.0dti zafira and the eml and coolant (looks like a radiator with a star in middle) light is on and the rev counter drops to zero it also runs rough and goes into limp mode.
I've read the codes and none are stored or present although the lights are on.   The lights do go out and the car runs fine for a while and then return.
Question is do any of you know anything about zafira dti's and ccould you give me some ideas of what to check/do to fix it.
Thanks for looking

Lee

Try the pedal trick, as it's an earlier model it may well work. Otherwise it's a code reader for a detailed list of faults.

if its the earlier version i'd be looking at the fuel pump or imobiliser.
is it not the same engine as fitted to the vectra B  :-/

Yes, VecB and ZafA share the engine. Needs the codes reading first rather than guesses ;) :y

Right  read codes with better reader and still none listed.  Car starts every time so dont think its an imobilizer issue but we have discovered it only does it when hot and clears when cold.  After a bit of searching we've found someone listing the same problem and says a new crank sensor fixed it.
Mate wants to try that tomorrow as he needs the car so i'll let know how that goes.

If the rev counter drops to zero the crank sensor is a reasonable place to start in the absence of any codes, I suppose. :y

Father in Law had this very issue with his, seems to be a very common problem.  Crank sensor was one of the main problems.  VX wanted about 700 to put right

Well so far so good  put new crank sensor on it and it seems to have cured the problem.

Hmmm...it would have stored the code, wonder if its not such a hot code reader which only accesses the present codes and not the non-present/stored ones

These engines use the crank sensor to run the rev counter, also a lot of the cheaper generic code readers will not communicate with Vx. diesels...

Hi Mark I tried a couple of readers first my elm one and then  a bosch kts200  which is a good reader also the lights were on when i read the codes and it said the eml was off on both readers so dont know what was happening there but since changing the crank sensor all is fine ( he says its better than ever).
