Q: MDS solenoid #4 fault P3435 - questioning dealership quote
After several hours in diagnosis, dealership quote is ~$560 for cylinder four solenoid and harness replacement. Will replace other 3 solenoids for total of $907. 1. Is this quote reasonable or high?
Three local repair shops said they do not perform this, waiting for a quote from a fourth. The only thing my lifetime extended warranty covered was the harness.
Would this quote include harness replacement for other three as well?
I realize that since this is MDS it affects my gas mileage but is this really an optional fix?
Would a local shop have ability to permanently or temporarily disable MDS?
My car has 103500 miles.
My car has an automatic transmission.
Hi Wilson. Let me try to answer your questions one at a time.
1) The quote for completing this service that you’ve listed is about average for dealerships. Generally, this is a dealer only repair.
2) You’ll have to contact the dealership to have them verify what is included in their services - we can’t answer that for you unfortunately.
3) Not really. The MDS not only impacts fuel efficiency but also emissions and vehicle performance. Not repairing this can result in a failed emissions test as well.
4) No - a local shop would likely not take on the responsibility of disabling this system.
You should contact the dealership to ask them about specifics about their estimate.
