how much i gonna spend for troubles?

Question

I have 2001 VW Passat 1.8 and today I got diagnostic trouble codes, and i wanted to ask how much i will spend of these for repairing?

Answer 1

P0012 Bank 1 specification not reached for adjustment to advance camshaft.

P0171 Fuel trim too lean Bank 1

P0333 Knock sensor signal too large.

P0411 Secondary air injection system fault

With a code for a lean running condition depending how lean it could of set a P0333 sensor code (knock sensor) and being to lean P0171 can be related to a lean condition where false air from the secondary air injection tube being disconnected and because of a knock sensor code condition the camshaft will not advance. Check the oil condition and the level. The cooling system also for any coolant leak. For now you only need to fix the lean running condition.
