Possible turbo issue? Engine much louder under acceleration & less go at speed

Well, what a story!

Chap said new turbo is goosed, and I agree, definitely rubbing the turbine/compressor when under load.

He did a scan of the car and found lots of faults. Other garage didn't mention any of them, so doubt they even scanned her, will not be using that place again, as did no better than my cheapo reader that said no faults live or stored lol.

Faults:

Digital diesel electronics (dde) (d50m57b1):
4212, 4222, 4232, 4242, 4252 and 4262 all glow plugs.
4332 rail pressure control valve
4521 charge air pressure control

Electronic transmission management (egs) (gs19a):
5141 no message, receiver EGS, transmitter DSC

Instrument cluster (ike):
(189) BD electronic braking force distribution
(245) F5 No CAN identification (ASC)

Multiple restraint systems (mrs):
80 (50) power supply

Antilock braking system with dsc (abs/dsc) (dxc8):
5EB1 steering-angle sensor, supply
D35C No message (transfer case 192)

Central body electrics (zke):
Door mirror, passengers side, horizontal adjustment, potentiometer
Door mirror, passengers side, vertical adjustment, potentiometer
Compartment sensor, passenger
Door mirror, drivers side, horizontal adjustment, potentiometer

Lamp check module (lcm):
0D, 7A, 7B, 7C, 8E, 8F, 92, 93, 94, 95, 96, 97, 99 - control unit and almost all lights faulty

Radio (rad) (radio):
Radio fault in power supply

Park distance control (pdc):
0022 22 acoustic generator, front, off

Seat/steering column memory (sm/slm):
0018 steering column, radial short circuit

On board monitor control panel (bmbt):
0001 01 control unit reset
0003 03 PL line, short curciut to ground

Park heating (sth) (zuheiz):
Undervoltage deactivation
Combustion air fan
Circulating pump

Telephone (tel) (telibus2):
97 bluetooth button jammed

So, anyone know where to start?

Chap said he cleared them all and she drove great except for the noise from turbo, but I picked her up and still a bad of crap, so unless they reappeared because he drove her, he not a clue how she should drive!

Arggghhhh.

Woah that's a hell of a list.....seems a tad odd to have that many,  have you had any battery issues? You seem to have a few errors associated with low voltages. The only thing I can see that could be affecting the turbo is the charge air sensor fault. Now I am not saying that's your issue. Personally your garage has said the new turbo is kippered so get that sorted first, have you got a warranty with it?

[moose04]

hi upex,  did he give you the dates the faults accured ? they may have had these one time glitches over the past few years and no longer have any relevance, we have  a few faults come up on the volvo trucks we run its never ending 99% of the falts happen for a split second, the computer records the fault it looks bad, mainly wiring faults/damp connectors or simular, if you,ve cleared the faults and the dash lights engine manament etc haven't reapeared carry on, the turbo front mate i would take the original to a turbo specialist have it rebuild, i bought a cast steel exhaust manifold same as yours and turbo is at central turbos in derby if its just an impeller shaft balance and seals £186 hopefully thats with a 12 months warranty

[henrym3]

Possible that when he cleared the codes especially the charge air one as Grumpywurzel said the vehicle drove fine for him and then the code came back or more than likely your right and he doesn't know how it should drive. Whatever is wrong there certainly shouldn't be a "noise" from the turbo. Another new turbo time, you'll be able to do it in half the time.

[Upex]

Have messaged seller and will be returning turbo once removed, seems like a decent show, so fingers crossed.

Re the codes, didn't give dates, but I think I caused the rail pressure one when raising oil pressure following turbo install, as undid rail pressure sensor to crank without starting.

Think I also caused the abs related system ones, as installed a piggy back circuit on the abs fuse and knocked it when reinstalling glove box, which threw all the abs related warning lights until I plugged it back in (wondered what the he'll had happen for a split second when it occurred lol) out of interest, I used that circuit as was the only ignition live I could find that maintained power when running as well. Anyone know of another as would rather not have it on the one if possible, more rather something less fundamental.

The error that bothers me most initially is the transfer box, no signal one, what the heck would this mean / lead to?

Regards battery issues, no, it's fairly new and strong as an ox, perhaps left over from previous owner, who did replace battery shortly before sale to me.

The funny thing is, with all 40 issues and a duff turbo, I've had no check engine lights, or any other warnings at all. Even garage man said to bring it back if light returns, and was surprised when I told him it never came on anyway (does light up when starting, so the bulb hasn't been removed!).

Also, was checking some readings via torque app, and coolant seems to be staying too cool. Highest I've seen it is 72, and although it's only like 6 degree outside, having been idling for a while, I'd expect it to be hotter. I'm suspecting a stuck open stat, but wonder what normal running temp is before I go changing it?

Cheers all, will keep you updated. Need to go read up on glow plug controller swap out and readings for testing the plugs (as don't know what normal, ok range of resistance is?)

Thanks all, till another day in the saga! 

[henrym3]

In some cases, doesn't the DME restrict boost pressure until you are up to working temperature. Don't know what the thermostat should open at on your diesel but 72c is way to low

[Upex]

That's interesting Henry, wonder if that's hindering my boost on new turbo (despite it catching).... Can't seem to find much online on that D35C No message (transfer case 192) code though, so any ideas on cause and cure would be great.

So, think I'll need to invest in a scanner code clearer, anyone know what type I need to be able to pull and reset these type of code? My generic multi car obd2 didn't pull any of these, not 1, ad I can't keep popping back to the garage and paying £50 a time to clear and see which I've fixed etc. Anyone have any recommendations?

The print out from garage has autolink on it, so ive googled and wonder if an autel autolink al519 or al619 will successfully pull these codes? Anyone have one or used one?

Cheers all

[ianst0028]

i have the autel mot pro ..... and a delphi laptop/tablet thing
the autel is ok for quick codes and the delphi is good for more in depth stuff

the 519 isnt the greatest neither is the 619 tbh ..... the 519 is probably the same level as the generic code reader you already have
the 619 is more in depth but wont allow you to do in depth component testing and may struggle on some bmw specific codes

looking at your list of faults ..... i'm thinking that they're historic codes and may not actually be having an effect on your problem now
hopefully your turbo guy will come good and sort that out ..... a new / unfaulty turbo should have you back up and loving the x5 again

[Upex]

Cheers Ian, yeah, fingers crossed.

What reader would you suggest? After a hand held as a laptop a pain, just need to pull and clear codes, so I can see what's stayed off, and what's come back after each fix etc.

[ianst0028]

i've sent you a p/m

[Upex]

Cool, will have a read, thanks.

[Upex]

Folks, I'm struggling to find much info on these 2

4332 rail pressure control valve
4521 charge air pressure contro

Do you think I could have caused them when unplugging the fuel rail sensor (one on rear of rail) when cranking over? And thus shouldn't worry about them yet,

If not, then what parts would or could be causing these?

Only thing I've linked, kind of, is the 4332 potentially being linked to part number 13537805733, pressure regulating valve, which is the one I disconnected to crank her over. As this valve is 500 quid, I'm keen to not swap it out unless can confirm it's duff etc.

Any input be great.

Am ordering new plugs and control unit, so hopefully that fix 6 of the issues lol. Is it ok to put a bit of penetrative fluid on the old plugs and leave it soak for a bit to try and free them up, really really keen to not have one break, especially as they clearly in poor condition...

Thanks all

[X5Sport]

Are the errors still present?  If not then don't worry about them.

[Upex]

Don't know, if I want her read again it's another £50 and given I've not done anything to remedy yet, don't see the point in dropping the extra cash. Once plugs and controller replaced, and a new, working turbo fitted, I'll need a read and reset then, unless she springs back to life without, so will know more then I guess, but trying to get ahead of the curve with possible issues so can hit them running once turbo and plugs sorted.

This is why I need a scanner than can pull the codes lol, can keep an eye on them then lol

[ianst0028]

I think the fuel pressure codes are when you built the oil pressure up for the turbo
tbh if she's starting ok i wouldn't do the glow plugs/controller at the moment I'd prioritise the turbo

shame you're so far away or i'd plug the diagnostics in for you

let us know what the turbo supplier says

[Upex]

Thanks Ian.

You think that turbo issues may have somehow done something to throw glow plug codes? Given all are marked faulty, and I have no idea when or if they have been changed, think I'll swap them out anyway, fairly cheap for something which is probably overdue and likely got some errors anyway, unless the turbo could cause the glow plug faults?

I'll change the status whilst at it to, as is running in 70s not 80s and judging by gague in cluster, it's been that way since we bought it!
