Mondeo Mk3 2.2 TDCi low idle on start

Recommended Posts

Hi I posted this in MOT/servicing and realised it should go in here so reposting. Hope that's OK.

Hi all, new member,  I've just bought a lovely 2.2 TDCi Ghia X Mk3 and I love it. So big, so comfortable, so economical etc.

So I bought it knowing there was an issue with a low idle on start.

The issue is that on start, thew engine idles around 600RPM for a few seconds (no throttle response) then kicks up to 8-900 and is fine from then on.

This was identified by the previous owner as an EGR valve issue. I had a mechanic look at it before buying and he confirmed the fault was the EGR valve.

Having looked into it, seemed like an easy fix, just blank the EGR valve, so I did (full blank no holes). The issue is still there, possibly less pronounced now (only a second or two before going up to normal idle, occasionally it doesn't happen at all), but I can't say for sure, as I only started it a few times before fitting the plate.

Otherwise seems fine, once it's running I haven't had any issues.

Any thoughts? Just leave it? Maybe change the fuel filter? Let me know what you think I'd be very grateful for your thoughts.

Cheers fellas.

pcm update will probably fix your issue, was a known issue if i remember right ( was a long time ago)

Thanks for the reply! I looked it up and found several other people describing the exact issue fixed with a PCM update, so it looks like you're probs bang on. Thanks a lot for the help.

I called a local tuning place (Avon Tuning) and they quoted £100 plus VAT - does that sound about right? Seems steep to me for what is presumably a straightforward job (correct me if I'm wrong).
