Troubles with my sons Fabia 2 1.2/12V from 2012 (CJPA).

Suddenly the EPC light went on, power loss and 3th cilinder failed. New spark plugs, coil and injector replaced, still same error. With a test I've seen low compression. Took off the head and an exhaust valve could not be closed due to the soot (EURO 95). All the valves out for inspection and cleaning: the exhaust ones where oké, 4 of the intake where bent and 2 strange model. Cleaned and polished the head, the valves in place and reassembling te engine. Result: same problem. Leak and compression test perfect, spark plug with coil out of the block, no ignition for the 3th, finally I found a broken wire in the loom 4cm near the (coil) connector. Soldered a piece of wire and the Fabia purrs like a kitten. Yesterday I mounted the air filter box of my Fabia 2 VRS into the 1.2 and a SW upgrade gives a nice 24 horses more (was 69, now 93@4651 rpm) and 151Nm@3636 rpm.

 

So very happy with these result all the work and time putten in the head and dis/reassembling.

Edit: CGPA iso CJPA.

 

Sorry
