Hi All

I jst got a call back from Crown Honda....

They want to start by replacing an injector £552.00 but think it may also need an ECU £1369.00

I explained that it was there for the ECU to be tested which it nows seems they can't do!

So, back to square one... it's 5.15 pm and they close at 6pm...

thanks for any further suggestions... joe
 
... best laid plans .............
they sound like plonkers to me. Very disappointing.
If it has detected a misfire it will probably have cut the fuelling to that cylinder, so it might look like the injector isn't working ......... if they are not clued up.
You can do the same swap with injectors if they really suspect it, clear code and re-start to see if the fault stays with the cylinder or the injector. Probably more the sort of thing your trusted mechanic will do than that main dealer. Most basic check is the injector coil resistance. Easy enough to check it opens and closes using a jump wire ......

Jocko's suggestion is looking more attractive.

Thanks for everones help so far...

I'm booking the ECU for a test/ repair but am unsure how to remove it. (ecutesting.com)

I believe it's next to the battery but some say it's behind the kick plate of the passenger seat.

Any tips on removing it would be very welcome for this nervous non-mechanic...

thanks again, joe

Hiya

I finally managed to remove the ECU- which wasn't easy without guidance.

I've now sent it off to ecutesting and will report in a few days with their result,

ongoing thanks, joe

Hi All

My update is that the ecu was tested, found faulty and re-built.

At £250 + Vat and postage this is far less than a replacement ecu which then needs to be coded to the car.

It was a long process finding a solution so thanks to all who posted suggestions.

I managed to re-fit the ecu and drive back to Yorkshire yesterday where I will have it looked over by a local, trusted mechanic,

joe

I've had several customer cars fixed at ECU all at reasonable cost. Glad your able to use the Jazz once again.

Interesting to see that that is a common problem on the Mk2 Jazz, according to ecutesting.com.

Really pleased to hear the car is back on the road for a fraction of the main dealers price.  :D

Good to hear another positive report about ECU testing. Thanks for posting back!

Useful to know that ECU faults can happen with this model. It is quite unusual these days but clearly anything is possible. Glad you got it sorted at reasonable cost.

Hi All

Having driven back to Yorkshire I have now had it serviced and checked over by my trusted local garage.
The mechanic said the engine was now running 'sweet as a nut'.

So, a story with a happy ending despite a very nervous 2 weeks in London,

thanks again all, joe

Sorry I didn't pick up your message, not been about for a while.

Glad to hear it's all fixed, I can see you got the same answer here that I've just sent you!  8)

Hiya

Yesterday my car went back into limp mode after the ECU was re-built.
This time a fault code for a different cylinder- #1 rather than #3.

I though this was the solution after a re-build by www.ecutesting.com but I've tried deleting the codes which return after the engine is switched on.

Any ideas? thanks, joe
