I have injector problems with my Skoda Octavia.

Hi,

My 2007 Skoda Octavia (a 1.4-litre with 90,000km on the clock) was misfiring badly for a good while before the engine warning light came on. The 'bank 1' oxygen sensor went so we replaced the sensor and the warning light went off. No faults were showing on the diagnostic tool (electrics diagnostics only), but the engine was still misfiring. Unburned fuel was found in cylinder 3, which we eventually got cleaned out.

The coil and spark plugs were testing and found to be firing so it looks like the fuel injector for this cylinder is the problem. I'm going to bring it to a main dealer to try resolve as I think best case is to re-program the injector or worst case, replace it. My question is, how much should this cost to do in best and worst case scenario?

Thanks! Linda

Hi Linda,

It certainly does sound like an injector issue - assuming the coil and plugs are fine. We'd suggest that the injectors are tested before hastily replacing them. Any decent garage will do that for you - it doesn't have to be a main dealer. From the information you've given us about the car, we don't believe you can re-program the injectors. It may be possible to refurbish them, but in most cases it's probably better just to replace it.

If that's what is needed, the cost of the part itself is well over €100, but no garage should charge you more than an hour of labour for replacing it, as it's a relatively easy job.

Hope that helps and you get sorted.
