If I have no joy with ebay seller, who has said he will check against my reg for the genuine Ford one and has said he will do it for £75 then I will look into these avenues. Thank you Valhalla. TBH I'm taking a gamble replacing the EGR, its a reccuring P0400 error code. A mate has had his smoke tester down the throttle body for me this morning and nothing showed up in terms of a vacum/air leak. So I'm hoping at 99000 miles its just time for a new part.  Have you checked Live data of EGR? Remove/check/clean it. Don't go throwing parts at it  Or get a fresh pair of eyes to look at it? You know what I mean, you can get blind to things  I've already ordered the new part from ebay before I seen your reply. We don't do a great deal of diagnostics so I don't know that much about testing the EGR valve. I was thinking if it's done 99k rather than taking off and cleaning just put a new one on, probably not the best way to do thing though tbh. I've got Forscan, Think diag (launch) or the Bosch KTS in terms of scanners/software. Can you advise what I should be looking for within live data? Cheers. |

You ought to be able to drive the egr valve to a commanded position and it’s feed back should say where it is….
So if you command it open, the feedback should say it is open….
I’m not sure with Forscan where you go to do this, having not done this on my Fiesta…

My approach to the sources of parts on my personal car is 1) Will this part failing likely cause an accident? (e.g. decent brake pads/tyres rather than cheapy ebay stuff) 2) Does the time/labour to fit this part cost more than the part itself? (there's no point saving £50-£100 on a clutch kit if the labour to replace the cheap clutch is £250) 3) Will this part failing leave me at the side of the road? (decent batteries etc.) 4) Is the factory/expensive part significantly better than the pattern option? (e.g. Factory/expensive parts coming with full fitting kits) ------------ You forgot to add... 5) Is is a customers car or your own car? I tend to fit Factory brakes and droplinks to my own cars - I cannot stand squeaky brakes and changing drop links every year. I tend to be more strict with my own cars, than with customer's cars, but not for the usual reasons above - which are all good and valid. In my own case, it's because I often need to move fast on getting a repair done, and therefore price is less important to me - I don't have to justify it to myself in the same way. So I go genuine Volvo for even things like filters for services (on the Volvo's, of course..... ) as I know they will slap-on and seal/work right first time. Also, I'm a snob when it comes to lifting my bonnet.....despite the clapped-out look of my cars from the outside.....  |

It is easy to up spec the parts on your own car when you getting trade discount and not paying the labour to fit them. Never forget when you paying full retail and proper rate per hour - it's not so nice.
Not that main dealer trade discount is huge these days...! |

You make me sound as though I know what I’m doing and what I’m talking about….  Seriously though, I’ve tested Vx egr valves on the bench, connect a power supply to the actuator coil, watch the valve move…,with a dvm on ohms range (20k should do it) measure the resistance of the feedback terminals…Vx was around 5k, connect one end of the terminals to the meter and the second probe to the middle terminal like on a potentiometer, as the solenoid is actuated, the reading should change, mine went from 2.5k to zero ( as near as dammit..), put the probe on the other outer terminal and reading should change to the maximum as seen from the reading with the probes on the two outer terminals…. It takes longer to describe than to perform the tests… Hth… |

Think diag could tell me the position of EGR at idle which was 2
Only other live data just said no faults.
It couldn't do the function to drive the egr valve.
I will have a look with Forscan on Monday.

As a non-pro mechanic I'm lucky in that my customer is pretty much only me! I also forgot to mention 6) Is the part a sensor/electronic input? (non OE sensors often provide erroneous data to the ECM) |

I often wish there were OEM parts available for the cars I work on most. They are often referred to as OEM quality but…..
The recently finished MGB GT had a coolant leak I traced to the heater valve, where it bolts to the head. Meticulously cleaned head, new valve and gasket- and it leaks.
So I took it off and put a straight edge across it to find the mounting flange has the profile of a banana. Easy enough to flatten out using my flat plate and abrasive paper, made a new gasket and all watertight, but OEM quality- I think not!

This is often the problem with classic parts - almost every make has this problem. The worst quality parts used to be Series Landrover - it really was a lottery whether the parts were any better than the ones coming off. Recently, things have got better, but you still pick carefully with brakes & steering. |
