Re: laguna II 1.dci - what to do next?

The wastegate solenoid is the unit with two vaccuum pipes going to it,the units can give problems (do it buzz at all with the ignition on?),and the pipes can block up with carbon too.Also check for splits/damage to pipes.The fact that the ECU has picked up on a fault with the unit usually means that the electronic side of it is faulty,but it's worth checking out all other possibilities before replacing it.

The glow plug code is thrown up due to a faulty plug,this won't cause your running faults but it would be worth checking and replacing them as neccessary.
