Hello,
Just wondering, could a blocked cat cause this code? Cheers Rob Edit, never mind |
Thanks for this thread - it has proved invaluable!
Just recently picked up an S60 D5 on an 03 plate with 117k for 1200 quid, though on the drive home, the dreaded 'engine service required' limp mode would chime in every time I tried to take it past 2.5k rpm... The car had a new intercooler in July this year and a new pattern fuel filter, which ruled them out, but here's what I worked through: -Top engine mount was shagged, so replaced it and at the same time changed thr turbo inlet pipe for a new pattern one. Still no change. . -Took EGR valve pipe off and decoked it, though it wasn't too bad compared to some I've seen on here. - Took of the turbo control valve and cleaned the tiny membrane/fiter with carb cleaner. This was completely blocked. Noticeable pick up in turbo response afterwards and engine seemed smoother, but still got limp mode at 2.5k. I was about to give in and get the codes read, when I read somewhere else that booting it hard in 4th gear from 40mph can 'exercise' and unstick the turbo vanes... I did this several times after putting 30 quids worth of Shell V Power in it, and with each 'boot' it got higher up the rev range before the limp mode cut in. After about five goes, it then pulled cleanly up to the red line with no limp mode! I have since given it a good shoeing in 3rd and 4th, and it seems to have cured it... It has returned a couple of times after prolonged low rpm driving around town in traffic, but then clears again once 'booted.' In short, I plan to run a couple of tanks of V Power and some redex through it to give it achance, but the above pretty much seems to have done the job! Hope this helps someone out in the same way the rest of this thread has done for me...! Nick |
I found on my 185hp engine that the cause was simply a loose hose clip on the turbo to the pipe beneath the engine.
A leak on the front engine mount was unrelated as the 185hp engine has an electronic servo for the turbo. |

Was having a look through ebay other day and found this
http://www.ebay.co.uk/itm/Turbo-Pres...8AAOSwFnFWFTJp Obviously listed for alfa models but is pierburg, looks to have same connector and has the white end part and is less than half the price of volvo one, |
Ecm 6805
My V70 D5 (2003 / 117K) is suffering this problem only under load:
If I don't boot it its fine If I do boot it goes in to limp Everytime I turn off and restart the "Engine Service Required" is cleared along with ECM 6805. I have so far cleaned the boost control valve (and it ran a little better) Notice lots of gunge in the intercooler pipe I removed to do the BCV, so I also cleaned this followed closly by me. Could this problem be vanes stuck or is an "Itallian service" required? |
I too have had this code/problem, unfortunatly for me it turned out to be the turbo that was shagged, bearings completly had it and possible cracked housing as i had a lot of hissing on boost, one recon turbo off ebay and now running properly for the first time since i bought the car.

Not posted on the board for ages but will add the following;
I had this problem on an intermittent basis. Codes were read by Volvo and confirmed the ECM-6805 code. I had engine mounts replaced, vac system tested, intercooler checked, smoke test for leaks, Alternator pulley clutch changed as it was faulty and it in itself can cause the same fault code according to the Dealer. They obviously checked the TCV etc etc as they had the car for two days with the Service manager himself working on it as he had more experience with the 'older' Volvo's There was nothing else to check and it was suggested the last thing would be to fit a new Turbo complete with vac actuator. This I got a quote for, 2 years ago at approx £1100 fully fitted by Volvo. I declined at the time as all the other work I had done along with this had added up a bit and I needed some time. The car continued to go into limp mode occasionally for a few weeks and then it decided to behave perfectly for a whole year. I have I will note always used BP Ultimate Diesel in the car. Anyway, just days before the next MOT I had Limp mode again three times. When the car went in for its MOT and service, Volvo said no codes were logged so there was no evidence to go on. Had the limp mode a few times after then it has been fine again for about 8 weeks, now I have had limp again three times in the last three weeks. So who knows. Im just settled to living with it. Its not a real problem. Its just so random. Mine usually comes in at half throttle or so when the revs get near 3000rpm. On occasions when I do give the car a good Italian style right foot, the problem does not occur. To me if a turbo is sticky it will either go to limp 'every time' you boot the car or on a regular basis. It will not do it a few times then be fine for months or a year then suddenly decide to stick again. It done it today, but at medium throttle on the way to work. On the way home it was perfect. Im living with it, life to short to stress over a minor annoyance. |
If you are hitting 3,000 rpm then surely you are over the speed limit,I have a few issues but at 2,500 rpm I am right on the limit, interesting post though on this code, got an Autel scanner today, got 5 codes showing including this one, will have to work through them with the help of (SiRobb) !
