235$ for puller replacement?

ANSWER : Replacing the system drier is absolutely essential. If the system has been open to the atmosphere (due to the leak in the condenser), the desiccant in the drier has been fully saturated with moisture. As far as the expansion valve, replacement is not normally implicated in a leak repair, in your case a leak in the condenser. To justify replacing the expansion valve, there would have to have been a diagnostic performed which proved a fault. If no diagnostic was performed, and there is no evidence of a fault, then it is pointless to replace the valve. But, again, drier replacement is absolutely essential. To add the drier to your order, you can simply add a note to the mechanic in your order and/or add it as a service (you will see a link that you can click on to "add services" or write in specific services).

ANSWER : Hi there:

If the mechanic completed the O2 sensor replacement, reset the codes and the error code was triggered again, it is possible that the catalytic converter is damaged and needs to be replaced. However, it’s also very common for the electrical harnesses that power these sensors to become frayed, damaged or faulty; which can also trigger the check engine light. It’s not advisable to drive a vehicle with a damaged catalytic converter for extended periods of time, as it can cause damage to internal engine components.

ANSWER : The water pump and timing belt should be replaced as a set if the coolant leaked on the belt. The coolant leaking on it will damage the belt.

ANSWER : I would ask the mechanic for the exact part number of the electronic component that he believes has failed. Or, at least have him "name" the part and indicate where in the column assembly the part resides. The steering column is made up of many parts, most of which are separately serviceable. As discussed below, limp mode (reduced power) has many, many causes. Consequently I would also ask the mechanic to explain to you EXACTLY how he arrived at his diagnosis and ALSO have him show you the exact test results, on a diagnostic tool, multi-meter, or scope, that has led him to conclude that the particular "module" has to be replaced. With no evidence and no intelligible confirmation you would be taking a risk.

YourMechanic does offer a reduced power (limp mode) diagnostic. If you request a reduced engine power diagnostic the responding certified mechanic will give you confirmation of the cause of the issue in your case. Typically, a vehicle’s powertrain control module (PCM) will have stored one or more diagnostic trouble codes that will identify the "general area" in which the fault lies in the engine management controls. Although the throttle control system is a common trouble area with reduced power, there are quite a few other components and systems that could come into play and, of course, there is always the possibility of multiple, or "coincident", faults. Here are some of the possibilities that YourMechanic dispatched technicians would consider:

Defective throttle position (TP) sensor
Defective oxygen sensor
Defective accelerator pedal position (APP) sensor
Loose or damaged wiring
Defective throttle body
Defective powertrain control module (PCM) (not typical; ONLY if a long, long list of other possibilities is ruled out)
Any fault/error that will affect drivability function
Any fault/error that will affect vehicle performance
A fault/error in the emissions system
A fault/error in the throttle control system
A fault/error in the transmission control system

If you request the recommended diagnostic the mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hi there. P0011 is the OBD-II generic code indicating the engine control module (ECM) has determined that the bank 1 intake camshaft is more advanced than what the ECM has commanded it be. This over-advanced condition could be during advancing or retarding of the camshaft timing. I would recommend reading this article as it will provide you with details as to what typically causes this code to trigger, and possible solutions.

ANSWER : The ball joint on this vehicle can be replaced separately from the lower control arm. However, on this vehicle it is also a known problem where the ball joint becomes loose inside the mounting in the lower control arm and will not hold tight any longer. This will require the entire lower control arm to be replaced. [https://www.yourmechanic.com/services/control-arm-assembly-replacement]

In order to know if just the ball joint or the whole complete lower control arm needs replaced, the lower ball joint will need to be disconnected from the steering knuckle and checked to see if it fits tight in the lower control arm. If it is loose, then replace control arm. If it fits tight then you will need to remove the ball joint from control arm and see if a new ball joint will fit tight in the control arm or control arm still will need to be replaced. This is why you were advised to replace the whole control arm.

ANSWER : Hi there. Anytime you replace major air conditioning system components like the AC compressor, it’s recommended to purchase all supporting hardware and replace it at the same time. AC works as a series of individual components working efficiently together to create cool air that flows into your cabin. As such, if you’re replacing the front expansion valve, it’s a good idea to replace the rear at the same time. This increases overall efficiency of the system, reduces the potential of small component failure and allows the parts you replaced to last longer.

ANSWER : Hello there. You might to read this article about the P0171 OBD-II trouble code; as it will give you ideas on causes and possible solutions.
