Need some advice from the collective experts here. Sonâ€™s GF has an 07 N12 auto with a timing and/or vanos issue. Wish I could recall exactly, its been a few months since BEST diagnosed it. The car has been serviced by both MAG and BEST in the past, including this issue. The bottom line is that this car is too expensive for a college student and has to go. She already has a replacement that is more reliable, so that is done deal. I am not familiar with the timing chain issues on the N12 per se but do know about the large amount of problems in the N14. I guess the question is whether to sell it as-is or dive in and make the repair first? 1. If the tensioner has allowed the chain to jump is it ok to run/drive it or will that cause more damage? (Its been parked since summer. ) The symptoms leading to this were that the car would run fine one day and then stall out and leave her stranded the next. 2. I really donâ€™t want to crack this open myself, but want to be able to tell buyers what they are up against. Ideas on what a DIY cost this might be? 3. Thoughts on value as is? It is a pretty well equipped pepper white version with auto climate, rain sensor,aftermarket radio, keyless start option etc. I think it has average mileage for the age. 4. If you are interested in it as-is let me know. Her family wants to get this sold by end of the month so they can let the insurance and registration go. Thanks in advance.
