After getting a P1113 fault code I took the car to the dealer and he said that the LP fuel pump was only delivering 3.5 bar when it should be doing 5 bar. First job therefore was to change the LP fuel pump.

 

Bought one from GSF and had my local mechanic fit it.

 

This did not cure the problem.

 

However, the dealer had said that he couldn't check the HP pump because this relies on getting sufficient pressure from the LP pump to work properly.

 

What happens is that I get the "Anti Pollution Fault" message followed by the "ESP/ASR not functioning" after I go above 2000rpm. The car then drives OK but won't go above 2000rpm.

 

If I start the car and leave it idling, it cuts out after about 2 minutes (less if I restart). Once I've driven it and got the two warning messages, I can then leave it idling and it doesn't cut out.

 

Can anyone confirm that this is the HP pump or do I need to take it back to the dealer for confirmation?

 

I also had a broken breather pipe at the same time the problem occurred (which I fixed back together), but assume that this is just co-oincidence?

Thanks for your post.

 

Was your car running OK when you first had the HP pump replaced?
