Hi,

I'm hoping someone more knowledgable on VW fault codes than me (which really wouldn't be hard <*** class="inlineimg" title="Embarrassment" src="http://www.savs.co.uk/images/smilies/redface.png" border="0" alt="" />) is able to help give me some advice before I try and raise it with VW customer care.

My VW Golf went in for a service and a diagnostic check on loss of power at an authorised VW repairer garage. I mentioned that a previous garage thought that it may be due to the EGR valve. They came up with a low pressure fault in the fuel pump and replaced this. When asked about the EGR they said everything was fine with it.

The next day, less than 12 hours later, I broke down on the motorway at peak time and had to get towed to the nearest authorised VW repairer garage. They did another diagnostic and said a piston in the EGR valve had seized and would need to be replaced, and also the catalyst had broken up and would need to be replaced. Total repair bill of just under £1k.

Looking at the diagnostic log from when the car was in for the service, I can see three faults.

6575 P0191 008
Fuel Rail Pressure Sensor Circuit
Range/Performance

7808 P1400 001
EGR Vacuum Regulator Solenoid Valve -N18-
Electrical malfunction in circuit

7863 P1455 008
Exhaust gas temperature sender 1 -G235
Implausible signal

Now I understand that the first fault is why the fuel pump was replaced but what i was wondering was is the first garage negligent in the other two faults that could have prevented my car from cutting out the next day? It amazes me that after spending a considerable amount of time in the garage, my car would break down the day after by chance.

Any thoughts would be appreciated. Thanks <*** class="inlineimg" title="Smile" src="http://www.savs.co.uk/images/smilies/smile.png" border="0" alt="" />
