Hi Tomas
Apologies for a delayed reply had Family Covid issues preventing me getting to a garage due to isolating. All ok now tho.
The emissions light came back on after 4 starts as my mate predicted so I took my car to a local specialist last week and they diagnosed the error code as a faulty glow plug in cylinder 1. They replaced all 4 glow plugs and I noted on the bill that 1 glow plug was 4 times the price of 1 of the other 3. Apparently VAG engines have a Smart glow plug which was the one that had gone faulty.
Note
specialist charged £296 For diagnosis and replacement of glow plugs
Skoda stealers wanted £120 For diagnosis and £306 for replacement of glow plugs.
So far car has started cleanly without delay though as fault was intermittent I won’t know for sometime if it’s fixed the issue or not.
