Car limped home injector issue

[octaviaguy2519]

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!

What engine is your car? Diagnosis will be quite different depending which.

 

Depending how handy you are it might be worth getting a multimeter out and checking for continuity around your injector wiring.

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

 

not handy with one , sorry!

Early versions of our engines (CAYC) had injector problems and later ones used a more reliable different make. Injectors can still fail at high mileage.

As the fault code said, injector 4 is the culprit or its associated wiring.

 

Here is a video showing how to do the tests and replace the injector. It was made using a different car make but the process is basically the same. As you say you are not handy with a multimeter I suggest you use a trusted garage.

Pretty sure it doesn't have coil packs.

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?

I don't know enough about common rail engines like yours to say for sure.  On an older PD engine there is absolutely no chance you could do it that quickly as it's quite an involved process involving stretch bolts etc.

 

However I think CR injectors are external (not under the cam cover) and not mechanically actuated like PD ones so it isn't out of the question.  I've changed injectors on older (80s/90s) petrol and diesel cars in not much more time than that.

Impossible on a PD as Valver16 says above and I also know when I had one changed on my 2.0 PD

 

This video seem to show it is very straight forward.

 

 

 

Hope this reassures you somewhat. Is the car OK now? Any fault codes?

 

[octaviaguy2519]

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?

[valver16]

Might be worth having a look at the wiring loom going to the injectors, if you aren't happy testing it properly with a multimeter then even just a visual inspection.

 

Other than that if I were you I'd be taking it into a VAG specialist and asking then to diagnose it.
