Hi All,

 

Recently, I am getting the EPC light on and it displays "engine fault : workshop". I visited the dealer for a scan and they said its the high pressure fuel pump. The EPC light is not persistent, sometimes it appears and goes away. They also advised to change the crankshaft sensor though its not in the fault code.

 

Any thoughts on this, any easy fixes? Seems the high pressure fuel pump is pretty costly.

 

Car: Skoda superb mk 2

 

Thanks in advance.

The Skoda mechanic changed the high pressure fuel pump and seems the fault still persists. :(

Did he check the fuel pressures before deploying the part cannon?

I don’t have a petrol engine in mine, but I would use these testers to check the pressures in a diesel.

Spill return is above 1 bar

Feed to HP pump above 6 bar.

And check the specific gravity of the fuel for contamination first.

I am not sure how he tested it, but he says that he swapped the HPFP with a spare one to check. Now he says its not the HPFP its the ECM which is faulty. I am bit confused.
