Fault codes on a 2004 Fabia vrs.

[chez]

Hi All.

 

I have a couple of issues with my vrs. I have four fault codes popping up on my vrs and are driving me mad. Was driving back in the rain yesterday and faults kept coming back right after I cleared them.

 

First one is fault code p0230 fuel pump relay circuit malfunction. When this one comes on, on its own the car will still drive OK but the cel light comes on. I can clear it and the car will still drive OK. Is this sounding like its faulty and I need a new one? Where does this relay live and how can I test it?

 

P0401pd is the next one I get. I think that’s due to having fitted a Egr blanking pipe. Do I need to get it mapped out? If so does anyone know anyone around Shropshire that could do this? Is it best to put Egr and new 90 degree top pipe back on? If so what’s the skoda part number for the top 90 degree pipe by the Egr?

 

The next two are the real problem. P20243pd turbo/supercharger wastegate regulating solenoid/valve a and P0246pd turbo/supercharger wastegate regulating solenoid valve a high. Both of these put it into limp home mode and won't rev past 2500. I can switch the car off and it will be OK for about 5-10 minutes then comes back on again. I've fitted a new map sensor and a new vacuum solenoid block on the front right strut and it fixed it for a bit.

 

Seems to happen most of the time in wet weather.

 

Any ideas?

 

Thanks

Hmm, that style of fault code looks weird to me, especially those last two - is one of those some kind of overboost fault code?  I am more used to the way VCDS lays out fault codes to be honest.

Not sure. It could be. It's on a launch creader 5 code reader.

It does sound like one of them faults could be overboost issue

Hopefully got a fuel pump relay on its way to fit and see what it does.
