Guys, My Gr'daughter has a prob with her X reg A class

Resolved Question:

Hello Guys, My Gr'daughter has a prob with her X reg A class Merc. I have no idea how cars of today actually work, but seems the diagnostic printout says :- 'P0100 Hot Film Mass Airflow Sensor Bank 2/5 Too Small - stored Code' and P0100 Hot Film Mass Airflow Sensor Bank 2/5 Spor Fault - Current Code'.
The car is with a local Hook garage which looks after the family cars, and absolutely first class. However, the mechanic said that the offending sensors were built into a unit which he has removed from the engine, and said this unit can be sent off for repair to a repair shop. He thought the cost would be about £200. He also said that reviews of these repair were mixed.
If the repair can be done successfully, then I will cover the cost for her. Question my friend - in your opinion, is it worth sending it to a repair shop for reconditioning, and if so, which would be the best, ***** ***** repair shop to send it to?
I would dearly like the car to be fixed and running again for her because otherwise, the car is in lovely condition.
Regards Warren

P0100 is indeed a mas airflow fault..usually rebuild or reconditioning is the best method due to high cost of aquiring new and having it recoded - you cant use second hand sending it out for repair of the ecu/afm unit is best method here..there are few places that does these repairs,have used them myself quite often with no problems..and well worth enquiring with below...I do hope this helps
