Late last year, I had an injector die; it was the injector in cylinder 3. The car sounded like an old VW panel van (the ones with the air-cooled engine) and it ran as lumpy as badly-mixed custard. The error code was P0203. The injector was replaced my the garage and the problem went away; job done.
Last weekend, I was on my way back down to Aberdeen from my Mum's house in Thurso, when the EML came on and "Engine Anti-Pollution Device Defective" flashed up on the MFD - but the engine still ran fine and pulled strong.
A couple of drives later and the light went out - phew, false alarm. But then it came back on. Curses.
I bought a code reader off eBay (ProScan V600 - I had actually ordered the V580 for £30 but the seller had run out of them, so he sent me the better model for no extra charge). It came up with the code P0202, and suggested that the problem was exactly the same as before, but with the injector/circuit for the no. 2 cylinder.
I am not currently experiencing any problems with the way the car drives (other than that one of the wheel bearings sounds distinctly knackered
) but I want to be able to sort this one out myself if possible. How easy is it to swap out an injector? I was thinking of switching the no.1 and no.2 injectors around and seeing if the fault code changes to P0201. But also, I want to have a spare injector.I'd also be interested in knowing why I have had one confirmed dead injector (the garage tested the resistance and it was off the scale) and one possibly dying one. Do injectors have a set life-span before they need to be replaced? The car has done nearly 84,000 miles and is 11 years old. Should I be buying 3 new injectors and replacing the ones in cylinders 1, 2 and 4? If I do need to buy an injector (or 3) what part number should I use? And would these be the same model of injector as used on the 2.0, or with mine being a 2.2, would they have picked an injector with a higher rate of flow? Is there any benefit from using injectors from a bigger engine (i.e. the 3.0 V6) or is that just stupid/pointless?
Your collective expertise and advice is, as always, much appreciated!
Cheers
Graeme
