Did you garage tell you what fault codes was logged before they deleted them? and did they retest the car to ensure these code didnt come back?
What scanner are you using?
I asume the cars an Automatic?
The two id be more inclined to have checked out is 16804/19722 both of which are cataylist and oxygen sensor fault bank 1..could well be bad post lambda sensor before cat converter might be causing the cataylist efficency fault unless the cat converter is gone in itself..not really somthing to overlook - 17704 is bad Coolant temperature sensor..again this sensor is primary for the ecu to know what temperature the engine is at coolant system wise to alter fuel/air..so might be something to replace maybe.... Also im not sure why you would be trying to get into A/T which normally is for Automatics or DSG boxes that are TCM controlled..being that yours is a manual then the scanner will obviously not see any transmission ecu codes hence the link error
Yeah i mean if the car seems to run ok as far your concerned - then it maybe worth leaving until the MOT is nearing maybe look into those codes i highlighted above if for emissions...normally if its old codes then they nerver really come back or still listed under history codes depends on the scanner they use to look at those..old codes never cause the engine light to flag up..but as above that about the best things to be checking..I do hope this helps..please dont forget to leave a rating before you log out..much appreciated
No problem Jim..if you ever need to ask anything else or need advice then just ask , Have great weekend
