Hello Folks

 

Had the 10 reg fabia mk2 1.6 tdi CAYA engine about 10 years,66k miles, haven't  done the diesel emmision fix.

Last couple of months, it developed a rough idel and annoying noise. Then last thursday, glow plug flashed and eningle management lit while driving, it turned out the inector 1 in faulty after VCDS scan. Car could still start but sounds not right, and glow plug flashes after start up.

 

Is the injector in faulty or the bad wiring?  

 

I've checked the resistance of the injectors. Injector 1 is 7.14,  can't get the figure from the rest injectors.

Tried to swap the connectors between injector 1 and 2, but the cable from the injector 2 is too short to reach injector 1. Car couldn't start with 3 injectors while injector 1's connector goes to the injector 2.

 

Just wanted to make sure that the new injector would fix this fault.

Can't source a new injector atm from well known parts store at the moment.

 

Thanks in advance.

It’s a known issue I replaced mine about two years ago it can lead to excessive pressure in bore and internal damage, cost me €320 for injector and puller got injector from local specialist and puller from eBay, try darkside developments for advice or and vw specialist 

It is a known issue with the 1.6 TDi. I had one go on my Roomster.

 

The job of replacing the injectors themselves isn't too difficult and if you're alright with a set of spanners you should manage no bother. But the new units do have to be coded to the car with VCDS as you might well know.

Thank your guys for the replies.

Do you change all of them, in pair or just replace the faulty one(ones)? 

I will keep this car for as long as it could last.

Yeah agreed with @sepulchraveand @joedemp just replace the faulty one. Obviously if you're feeling flush you can do all four, they will probably need doing eventually but they are items that you can just replace as they fail. Gives you time to save up for them! 

Thanks for the suggestions.

Now I just need to find the part.

Will try some local diesel specialists as new part seems lack of supply.

There's plenty available, they're crazy money though, you might be able to get yours refurbished.

The price for a brand-new one is around £350, and a refurbished one somewhere £150 to 200,covering 3months to 1 year warranty.

I might just wait a bit for the brand new one.

It's a Siemens VDO. 

Is this the only brand that making the new part?

 

 

When the injectors go on these, do they all go within a short amount of time or is it a case that one can go, but the rest might last for another 30,000 miles+?

I have no idea, feeling like they are consumable parts. 

Hope the rest on my car could last a considerable time. If not, I will try change earlier after like reduced mpg, rough idle, annoying noise and shake on idle happen almost at same time again.
