hi all, excuse the brief title but dont know how or what to add to it to describe the ongoing problem. Started to happen a few months ago where the glow plug light would come on and find that No 1 injector had failed. Rough running , no acceleration etc. Cant have surely as only 20k miles old. Reset the fault and car now drives as it should. Driven about 100 miles and it goes again. Reset the fault code etc etc.......this has been happening now for a few months now.       No other fault codes to suggest anything else.

         So question is , is there a sensor anywhere that may be linked, maybe a cam / crank snsor that is telling just No1 inj to quit ?

Engine code and year are useful info to add.

1.6L CAYC engine is notorious for injector failure.  It was injector 1 that failed first on mine (usually the first to go) and the garage also changed injector 2 it was not showing good signs. There are enough people who have said that once an injector fails on this engine, the others will fail soon afterwards.

I had the other two injectors changed by a VAG specialist garage at a lower cost within a month before they could fail.

My car might be considered an old car but it suits my needs perfectly so I have chosen to keep the car maintained rather than buy a newer model with high depreciation.

 

When my first injector failed the car could be restarted normally but it soon failed again.

This engine was the subject of a "dieselgate" improvement. It was optional but dealers followed the VAG line by saying it was a mandatory recall. It wasn't.

It consisted of a software change plus an "air straightener" in the hose after the air filter.

If you have this added part it is a sign that the service action (as they called it) has been carried out. This service action can cause other parts to fail - especially the EGR valve and, say some people, injectors.

Compensation was paid to owners who claimed but the scheme has now closed.
