New EGR Valve

Today i am a happy man. After having my EML light on for a couple of months i decided to buy a hand held reader, got one off EBAY for £15. It came up with codes for my EGR valve p4030 4050. Having read a couple of post saying it would not effect the engine i left it for a couple of months, but slowly i started getting black smoke on exeleration and a loss of power when the turbo was due to kick in. Again i went to EBAY to purchase a new EGR valve at a cost of £120 from Hatfield Jaguar Hull (Hatfield Liverpool wanted £170 dont know why). The old EGR valve had broken under the electrical conection, there are two cogs inside, one with two small pins on and both of these had snapped so the valve was always closed. I read a couple of posts explainig how to remove the valve, so off i went and replaced it, i dont normally work on my cars so when i completed the job all on ones own i can say i was over the moon. The result was my 2.2D back the way she was when i first got her. Without this great forum i would still be scratching my head to what was up, so anyone with these EML codes check out your EGR valve, not a hard job honestly. I also fitted a blanking plate with a 8mm hole in dont know if this will keep the gunge down as the old valve was really dirty. Once again thanks for all the great advice on here long may it continue. Tony

Well done
Its great to do things yourself occasionally for that sense of achievement, glad you sorted it out
I shall be doing this myself fairly soon.
Great to hear your luck, what reader did you buy. Can you send me a link. There are so many on e bay you never know if they will actualy work.

Thanks
I changed my EGR twice in last 3 years and seems is EGR problem coming back again in my Jag.

I'd be interested in which specific Diagnostic Code Reader you bought - I've tried two different ELM 327 units from eBay, but despite in depth technical help from both suppliers the units would not talk to my 2005 2.0D x type. Both suppliers were very good and took the units back and reimbursed me fully.
I also had the 2 pins break off on one of the gear wheels. This seemed to be the only problem with the unit, so I stripped the gear wheel out, knocked out the two remaining stubs left in the gear, and bodged it up with 2 self-tapping screws. After fitting the screws, I cut their heads off to leave just the shanks. Re-fitted the unit and it worked well for many months.

In the meantime I purchased a new EGR valve, and fitted that, but I have kept the old unit as a usefeul spare. One day I intend to replace the bodged screws with steel dowel of the correct diameter.

Perhaps if you have kept the old unit you too can 'manufacture' a handy spare. Might be worth doing at the prices these valves are fetching.
Any chance on the link for the code reader.

Thanks
Somebody's is going to retire on the price of these EGR's I think - when I replaced mine the first time I think it was only £80 for the part. You were lucky it packed up in the closed position, I think if it gets stuck open then you can't start the engine.

Funny you should say that. I can report that this statement is in fact true. JagAssist fitted a homemade blanking plate until I could get it to the dealers (under warrant). Details in this thread from last December.
This is the same model of EML reader I have U480 OBD2 OBDII CAN BUS Code Engine Scanner Reader Auto Car Diagnostic Interface | eBay
Hope the link works and sorry for delay in answering your question been away from computer. Tony
