Hello and welcome to JustAnswer!

The EGR and EGR flow control valve would cause an engine light but it doesn't appear they would cause what you're describing. These are both on the engine.

Does the noise come from the radio area in the dash, or are you hearing something through the speakers?

I'm unable to talk on the phone and am a full time tech at work. I'm unable to respond immediately. If a phone call is a necessity I can open the question for others and allow you to wait and see if another expert will respond.

Hi .

Before i call you we need to set a few issue clear .

The check engine light is Flashing or coming on and off randomly.

Now for the dealer to come out with you needing a new EGR ? what was the malfunction code for them to say this.

Remember when the check engine light comes ON then there must be a code (EGR)

I need these code to continue with this and call you on the phone.


Customer: replied 15 days ago.
A) They did not give the codes
B) Stated that codes showed needing to replace 1 egr valve, 1 throttle body/egr, 6 glow plugs, 1 battery.However
A) yes I replaced battery
B) Ive had one glow plug out for 3 years no change there
When I enquired re: relativity of egr and throttle body replacement relavant to current issue... answer was they are not connected, but wanted me to know these should be done.More often than not the ETC warning light leads the pack and some times stays blinking after others stop. When this happens and it can do it once in a day, or continually on an off through the day. Does not matter running, parked, smooth or bumpy. Can not make it happen. If I stop and turn off then go again it may do again right away or hour later. All the warning lights goon and off at a blinking pace..... Another indicater that may point you some where is that the dash lights fuse has been going out regulary. I think this is a strong clue, or is simply casued by the other. Have los that fuse about every 2 wks for a couple of months. That's new and seems regular. I don't know if perhaps I put the wrong size fuse in it. Ill have to look?When light go bugy, so also spped dial goes to 0 enven at 0 and tack goes nuts...Little to no noticeable running operttion change.Of course cruies has to be reset. Usually rests by simple reseting, but om times have to turn engine off ans restart before working again.Hopefully this may help

Hi .

This is a hands on job just giving you an idea may just lead to a run around .

Having the codes would be very helpful. to me sounds like a problem with the EGR and crank sensor ?
