Hello and thank you for using JustAnswer. My name is***** am a Vehicle Master Tech/MOT Tester located in the UK and I will do my best to assist you. During this conversation, you will be given an automated offer for a phone call.I don’t personally offer this service. I’m sorry that you’re having trouble with your vehicle. Please understand that I do not know your knowledge or capabilities so I may need to ask questions to find out basic information to help solve your specific problem. My aim is to give you the best advice possible and to help you. Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible. Firstly can i ask who i am speaking with today?
- Where exactly did you acquire the EGR from?
- Do you have a note of the fault codes if any that was stored prior to the EGR being replaced?
Ok. Firstly you need to establish why the EGR is faulty. Ideally tests need to be performed in regards ***** *****
A. Does the EGR function?
B. Is it getting getting power, signal command from ecm,grounds, you need to know if the egr is able to be commanded to open and close. component activation on scantool and live data can verify all this?
C. Is the valve stuck with carbon? given you have had it changed then you could likely rule that out. Is the EGR circuit blocked resulting in low flow codes being set? those are the questions that need to be answered or tested.. Obviously some aftermarket components can be a good alternative and its not unknown to get faulty ones,but often it best in the long run to fit a genuine unit if you can.i can say for sure if genuine one will solve your issue.based on what the fault codes are saying and the series of checks ive outlined above would likely answer that based on the findings.
Totally understand. aftermarket ones can be ,but unless you get the proper testing done to find out why the EGR is faulty as ive outlined above then you'll never be confident enough to go ahead and get a genuine one installed.you need someone who can properly diagnose and test the EGR system first before committing to a genuine part.its always easy to assume when a EGR code is flagged the EGR is faulty.in some cases its not it could be control/command issue or even the valve itself stuck with carbon.
It generally doesn't have to be "specialist" unless that's the route you prefer to take albeit more expensive. Most decent reputable garages nowadays should be able to carry out the the same procedure in testing so long as they have decent scantool and upto date technical data to guide them through the testing process based on what codes are being set in the ecm.thats the way it should be done.i know Halfords is pretty unlikely to go that far to be honest.
Any other questions?
No problem, glad its helped you in the right direction at least. hope you get it sorted out.
