C30 Engine : Still no boost after systematically going through stuff

[goltho]

Daughter bought her 59-plate 1.6D C30 15 months ago as a used purchase from our Ford main dealer (somewhat impulsively, I wasn't consulted as I'd normally be ). It's done 90k. Previous owner was apparently a 'self-employed mechanic'.

I've driven it infrequently but have noticed it lacks power. REALLY lacks power. It seems it's always been this way since purchase. I serviced it a couple of weeks ago and gave it a proper once-over including a full Autel diagnostic check. No relevant codes, only old ones relating to lights.

Since then, I've:
• removed, cleaned & refitted the EGR valve which wasn't in bad shape but was a little reluctant to spring back when turning the top spring swivel
• removed, checked & refitted the turbo & waste gate; both appear in good order
• checked every vacuum pipe I can find for leaks & splits; none found

However since refitting the EGR valve, it's throwing P1412, P0489, P042E and P0406 errors. I would guess the actuator sticking open (P042E) will be responsible for all the codes seeing as there were none previously. I'm therefore fitting a new valve later this week.

Anyone have any experience? The car runs smoothly and revs as it should (not limp) but slowly and with no boost. 0-60mph take 18.5 seconds contrasted with the normal 11 or so rating.

As a footnote and as an apparent co-incidence the anti-skid service warning comes on 3 out of 4 times when started, and remains on until TC is turned off temporarily on the stalk. No errors show for that on the diagnostics however and I've not come across it before (I'm a Peugeot man lol).

Any insight will be much appreciated. Thanks.

Depending how these engines are set up, you wont necessarily get any fault code if you are simply getting a boost leak. Id want to test for that first

Test with a gauge?

anti skid error is due to the EGR, whenever you disconnect the EGR after a while the antiskid warning pops up every sodding time. Its a weird quirk that makes no sense. EGR issues, usually restrict rpm to 3k max, and its very slow getting to 3k. EGR issues can also short the 5V power supply, the same power supply that powers the fuel pressure sensor, thereby shutting the engine down randomly. I had some fun and games with mine i can tell you lol. However, with it disconnected and therefor value in closed position, my car would boost fine, the only issue was the antiskid nag. I managed to snag a brand new oem unit for £30 on ebay.

Random or what?? What chance does a chap have when applying the normal rules of technology in a process of elimination if you're up against that? Dear god.

Thanks for the info, much appreciated. It provides some more reasonable suspicion towards the EGR, so roll on Friday. I'll update for those coming after us lol.

PS: Jut read your edit at the end. I've disconnected the EGR several times but it makes no difference. I did think it should.

Which unit do you mean?

Let us know how you get on.

Oh you need to reset EGR adaptions when fitting a new EGR, im not sure how important it is mind. I assume its due to the capacitors in top. They all vary a little. You will need a copy of VIDA to do that, you might get away with not doing it though.

I'll look at that, thanks. I have access to the top-range Autel machine which allegedly does everything VIDA does but we'll see.

Which new unit did you get on eBay for £30?

[daniel84uk]

I just meant a new oem egr value.

Volvo has its own subset of trouble codes and many many diagnostic procedures. The p error codes above are generic. ive found instances where generic codes that usually meant a value was too low, actually meant too high when you look up the code and cross reference with volvos. Hopefully the Autel has an egr adaptions reset

Gotcha. I ordered a new EGR tonight for £38 from Amazon for Friday delivery. £4 more than eBay but I want to get it sorted for the weekend, please god.

These P code are indeed generic and obtained from a quick app scan. The Autel belongs to my buddy. What are my options for a copy of VIDA? I use a dedicated laptop with various proprietary software e.g. Peugeot Planet 2000.
