Re: Dreaded coil warning in my Skoda Rapid TDI

I had exact same problem in my Polo 1.5 TDI. Turned out to be injector failure. Had to change two injectors (25k for each). Now its been approximately 3000 km since I changed injectors and every thing looks fine.

Re: Dreaded coil warning in my Skoda Rapid TDI

From my experience with the similar injectors (continental) on the ford figo tdci (gen 1) they are a relatively easy thing to fix now. Most injector shops manage to fix these and sort these out to be running as good as new . Try asking around with FNGs on whom to go to, there usually is some sort of injector specialist in most cities/towns.

An injector service for 4 injectors cost around 15-20k depending on what all they replace , its cheaper if they just manage to sort it out by cleaning and re-calibrating.

Re: Dreaded coil warning in my Skoda Rapid TDI

I have extensively read about these injector failures. I would advise since the error has gone and the car is just fine, just run your car with liqui moly diesel additive twice just for extra safety. And regularly use such additives.

You have a healthy running. This shouldn't have happened but anyways, keep a bottle of additive in the car. Use it once atleast 3-4 full tanks.

I use IFTEX System-D since the last 2 years on my 1.6 TDI. Bought it from a BPCL pump. Works well.

Secondly, I would advise to get the car scanned just for the sake of it and for knowledge.

Thirdly, if you want to be extra cautious you can go ahead and change the diesel filter.

This is the cheapest alternative as of now. I have read at many places where the glow plug sign goes off when run on fuel with additive. You can try this too.

Good luck

Re: Dreaded coil warning in my Skoda Rapid TDI

My dad has a 2011 Vento 1.6 TDI and right on its first long distance trip this coil lamp comes and since its the first of his many German car he purchased he had no idea what this meant and since we were on a deserted bit between Madurai and Tirunelveli bypass we couldn't get the ASS, so we turn off the engine wait 10 mins turn on again and no warning lamp and the car performs normally and even till date after clocking more than 2 lakh kilometres in the same car the warning never came (Talk about pre localisation quality). So your problem looks a bit like mine as your Skoda is performing normally now , might be just a one off but to be on the safer side do get it checked once.

Your post is a charming coincidence, Sierra. I was at Skoda today for my 75K service and (with the fear of the past coil warning lamp lingering) waited for them to get over with the scan. No errors and everything is working like a charm.

I religiously refill at quater-tank+ and am using IFTEX System D with every fill.
