63' D4 Eml p1407 code

[DavebV60]

Hi Everybody!

Have done a good search of the forum and found a few answers, but seems most thread never come up with a definative answer!

It was a fair while ago my v60 brought the EML on with this fault. But untill now I haven't been bothered because it has no effect on the car! (even start stop still works!!)
Car is a v60, late 2013, d4 (5 cylinder diesel engine), 90k miles.

Using my super cheap code reader it brings up p1407 (egr pressure low or something, can't remember the exact wording)

SO after searching this forum, i have....

Removed cleaned, and refitted the egr valve pipes and cooler. No change.
Removed and cleaned the intercooler MAP sensor, cleaned and refitted. No change.

Now i have read the map sensor is a common issue. However I don't want to spend £80 odd on a sensor not being 100% sure if this is the issue. But also read something about DPF pressure sensors! So this could get expensive fast.

Is it worth me trying to get the car code read proper on vida? Will this tell me more?! Or find someone close to me (i'm in chelmsford, essex).
I Am a mechanic by trade and REALLY don't want to give he dealer 70 odd quid for diag for what is probably just a guess by them aswell!

Cheers
Dave

Did you have any joy here Dave?
Having the same problem on my 2013 D4 with 96k miles.

I had a mechanic friend look at the obvious ones and he saw no issues. Don’t want to give to Volvo as I think they will just change the EGR without properly fault finding.

Cheers,
Andrew

Have you checked the return hose from the intercooler ?
The one on my car split at the elbow under the air filter box. The replacement part had an outer sleeve over this elbow which was missing from the original hose. When the hose splits you lose all boost, a tiny crack or split might be letting enough air through but the car is detecting a drop which is what it is flagging.

The other part I've had to replace on my 2011 version of this engine is the boost control valve.

Also check the electronic cable connection at the drive belt end of the injection rail. Mine had worked loose enough to trigger a low boost signal. The car would drive fine except when cold and about 1 mile into any journey. Back off the throttle, back on with a light load and the boost would fall off. Switch off and restart cured it until the next cold start.

Hi guys,

In the end I took a stab in the dark and ordered the map sensor from Volvo, there is a Bristol dealership that do trade discounted parts on eBay so I saved myself 17 quid odd. Still made it 86quid iirc.
When the sensor arrived, it has superceded parts number again to a new number that is different to all other numbers mentioned on this forum!
Turns out this can be had for around 40quid on eBay, genuine Bosch

But on the plus side it fixed the issue and 600miles, no light on so I'm happy!

New number is 0261 230 296

Can you send the Volvo partnumber? I have exactly the same issue. Went to the Volvo dealer here in Hungary and they want to replace some EGR parts costing a fortune. if it's really just the Map sensor costing around £80 I rather go for that first to give it a try.

Thanks
