Focus MkII TDCi EGR fault
Focus MkII 1.6 TDCi 2007 reg
EGR fault caused the car to get into limp mode. Tried the intake cleaner with EGR being removed and manually cleaned, but that didn't help. Following ECU reset, the limp mode would come back a few minutes later. Being absolutely assured that this was caused by an EGR valve fault, I had the entire EGR valve assembly replaced with a brand new one. Since Ford OEM was out of stock decided to buy a new one from TPUK. Unfortunately, just 1 day after the EGR replacement, limp mode kicked-in again. As per the service station the following codes are active: - P0490 EGR control permanent - 042F1 unknown fault code I am totally in the dark and the service station gave up. Taking the risk to order another EGR valve (Ford OEM) would be a disaster. So far the testing/cleaning/replacement cost more than £500. I also have my doubts whether the EGR valve is to blame. Any ideas how to do a proper troubleshooting? EGR delete and remapping is an option as well, even though I couldn't find any info on the web that such a thing has been done on the MkII Focus. |
Why start another thread with the exact same questions? Take it back to where it was originally mis-diagnosed, get them to replace your original parts and get your money back, then take the car to a garage that knows what they are doing.

The Vauxhall garage where i worked had to rectify various jobs hey had after they had been misdiagnosed and the original bill refunded. |
You can also speak to Lee at RSR that are based near the Ford Garage in Speke

Because RichieST I'm not a lawyer nor a kickboxer. Just an engineer trying to figure out what is wrong with my Focus, since no service station managed to do so. I believe this is the whole idea of having this forum. If you can help out giving your feedback on a technical matter it would be most helpful, otherwise just ignore this thread.:grin:
On your original thread I suggested you check for loose or split hoses and any damage to wiring looms. Have you done this yet? |

Yes of course hoses and wiring has been checked. Nothing wrong. Unfortunately since I don't have any wiring diagrams I couldn't check for continuity on the wires running from the EGR to the ECU. I don't think they have done this at the service station either...most mechanics are basically replace and see what happens!
