i have a 2004 S-type with 4.2L and 65000 mi. Dealership service tells me i need a new "complete variable valve unit" for $3200. How can i best verify this? The check engine light is on but the car runs great.
Hello and welcome to justanswer.com

Did the dealer give you that fault code number?
Customer: replied 4 years ago.

I think i sent you the fault codes yesterday. did you get them?

No please send them again.
Customer: replied 4 years ago.

fault codes P1384 and P0171

Thanks.

Was the price they quoted you both parts and labor to replace the VVT unit assembly? Can I have the last six digits of your VIN?
Customer: replied 4 years ago.

yes, price included parts and labor. last six VIN = M98315


 


Couldn't those codes also mean something simpler?

Since you have both a bank 1 lean fault as well as the VVT position fault it is most likely a cam timing problem. Either the timing has jumped or there is a problem with the variable valve timing. As far as the cost the estimate is accurate although on the higher end. The part is costly and there is some disassembly involved. Sorry to confirm the bad news.
