Hello

I have some fault codes with my Touran, some not so serious, but two of them bothers me. Occasionally the steering wheel starts to shudder or vibrate and it comes a strange sound from underneath the engine bay, maybe power steering pump? I have fault codes both for steering control module and ignition lock. Is it possible these are related, or do I have both a faulty ingnition lock and a control module/steering rack problem?
