Thanks! Does this seem like it could be the case in your view? Also, if the "new injector" that was installed wasnt coded in VCDS... would this cause a short?

An update to this! Had an auto electrician take a look. He said the new injector installed is shorting the circuit, and that's why its not working. He believes this is because a non-VW injector was installed that isnt right, and installing a VW injector should resolve it...

Damnit, was always going to be the case wasn’t it! Stupid question, but what is the benefit to probing? Would that just show the wiring loom needs replacing or is there a chance only a part of it does and that’s easier cheaper, or the part going to injector 4 alone could be replaced?

Looks to be CAYC

Can't find the engine code... hmm. It's a 2010 1.6TDi if thats helpful in terms of code? Sorry, you're being really helpful!

It clears then comes back when engine started. The person who fitted the injector did so without diagnosing the fault fully from what I see, and its cost me £400 as they arent cheap injectors! So I'd rather not have this person do this.

Makes sense what you say on the loom for sure. Assume whole loom is replaced not just a part to the one injector? No real symptoms to be honest, car was driving fine and then it just went into limp mode and had that error. Is replacing the wiring loom difficult? Something I could do?

Unfortunately my skills only go as far as checking the fault codes, can't do anything else! Fault code hasnt changed. I did remove the cable into injector 4 and sprayed with some contact cleaner but its not made any difference.

Thanks! Code error is the below: ============1============== P0204 Raw code: 0204 ECU: Engine control unit Status: Pending OBDII: Injector 4 - circuit malfunction Skoda: Injector 4 Control Circuit This happened, so I had the injector replaced. It cleared it for about 100 miles and now showing again. Car in limp mode and stuttering.

Hello I had an injector replaced and the vehicle is still not running correctly, with limp mode up and still faults with injector. Is it possible this is because the injector was not coded on VCDS? I am under impression from things I've read that can be the case. If so, what's the quickest/cheapest way to get that done? Thanks David

Car drove fine for 100 miles or so, now same thing happened again. Same error codes coming up. Can see the injector was changed... what could be the source now? Any ideas? Would the same injector fail so quickly again?

Thanks all had a mobile mechanic out and he said he replaced the injector as it was faulty, cost was £400 labour and parts. I wasn’t home and gf answered door etc, apparently he was done in around 15 minutes. does this seem likely to replace an injector in 15 minutes? Know they’re expensive parts so the cost of the part would be high, but surely it takes longer than 15 minutes if that was what he did?

Thanks! Car is a 1.6TDI, so actually I don’t think it has a coil pack? not handy with one , sorry!

Car limped home - engine light on flashing. In limp mode, no issue before it happened! scan shows this: P0204 Raw code: 0204 ECU: Engine control unit Status: Pending OBDII: Injector 4 - circuit malfunction Skoda: Injector 4 Control Circuit I read about replacing coil pack and it can help solve it. Can anyone link to the item I need to buy and is there a guide to fixing? thanks!
