#498170 Guide: Fitting Egr Blanking Plate 1.6tdci Engine

Posted by pauljoanss on 25 June 2015 - 12:38 AM

What car does she have ?
Fit the blank & drive the car & see what happens.
Any OBD II reader off ebay should be fine ( £15 approx. )

The car is a 2007 1.6 TDCI Estate,I fitted blanking plate and returned car to daughter. It seemed to run well, fault still shows on OBD and no engine failure light on dash, but that had disappeared anyway before fitting plate. Will see what happens in next few weeks.

Fitting dd not go well, here are some notes which may help others,
1. I managed to crack the windscreen when removing the top cover strip under the wipers. HOW? With all clips removed it just would not come away from one particular point under the windscreen, so extra force (not a lot) was used resulting in crack. On examination it appears some excessive mastic from under the windscreen had come out and stuck the cover plate to the screen. Even knowing this now, I am not sure there is anything I could have done different, insurance excess £75.
2. Fixing nut holding EGR cooler was very difficult to access and immpossible to see. A 10mm socket appeared to fit but when engaged with 1/4" adapter it keep slipping off, after some thought I realised the thread length was very long and interferred with end of adaptor in socket prevented proper engagement. Had to only slightly engage adaptor to give room for thread length and allow socket to fully engage on nut.
3. Blanking plate not symmetrical, you need to study manifold shape to determine direction of fitting, not easy as difficult to see. To aid visual access I lifted out the fuel filter (while still connected)
4. When finally fitted and clamped up I noticed some gasket 'hanging' out from the joint. Not happy and wondered if gasket wrongly fitted. I unclamped the joint, removed the plate, removed both clamping screws and moved the EGR valve away as far as possible to inspect the gasket. All was well, the gasket fully covered the mating faces and was oversize at one point, producing the overhang.

As you can see, I did not find this job particularly easy or cheap, maybe I am useless or maybe a bit unlucky.

Still unsure about these OBD devices, I read about some that will do some very fancy stuff, while mine does not even seem able to delete a basic fault code. Need to do more research.

Is that code present before blanking the E.G.R.V. ? - If yes I suspect a partially blocked / faulty E.G.R.V.

Yes it is.
As this is my daughter's car I have not got the day to day knowledge of dashboard warnings and limp home events. This morning I drove it and engine light was on, checked with ODB and code was present. Later, had car running in drive (stationary), no engine warning light showing but still code showing as current on ODB. Using "Torque" app on android device to read ODB and seems to be no way to delete fault.
I am going to fit blanking plate this afternoon but have little confidence of clearing fault code or preventing more limp home sessions.
I "look after" 3 ford cars in our family, maybe I need to invest in better ODB stuff? Any advice.

The basic logic is by blanking the E.G.R.V. recirculated waste exhaust gases can no longer clog up the inlet manifold, which then inhibit engine performance and also clog an unblanked E.G.R.V.
New E.G.R.V.'s are expensive, a blanking plate is around £5
Unfortunately Euro 4 onwards blanking tends to illuminate the E.M.L. which most people erase using an O.B.D. II reader periodically

Many thanks, it is what I expected, eg the EML fault will still show and maybe this is not related to the occasional limp home mode.(note correction to my post, I now have the car and see that the EML warning light is always on.)

PS additional info - now I have the car I have just run the OBD thingy and full message is
"P0405 - Powertrain
Exhaust Gas Recirculation Sensor "A"
Circuit Low"
