Car goes into limp mode. Code 203 on diagnostics IE No 3 injector. This has cleared in the past. Why? Does it need new

 

injector? It is an Octavia Greenline TDI CR.

It might just be sticking slightly and need a clean. I would just try some injector cleaner or have them ultra-sonically cleaned. Also try running some super diesel such as BP Ultimate or Shell Vpower. They have cleaners mixed in so should help clean the internals.

Thanks for the idea I might try Halfords and give the whole engine a clean.
