4th injector issue....ERR3337

Right so been to the local landie specialists and it seems my 4th injector is buggered and of course its the dreaded ERR3337. As mine is an EDC auto.

So.............Am I screwed? Any ideas? Anyone with a spare? Anyone know a good place to recondition?............

Thanks in advance for any advice.

Best option

Second best option

Or find out if this has your part on it

Either way I don't think you will find injector 4 - if you find it new you can bet it will cost 4 figures
