ITS THE NOT THE DPF....PLEASE HELP E60 530D

Postby DRTVRDEMON » Mon, 24 Oct 2011 18:47:23 UTC

Please help, detaield info of the history here.

BMW 530d E60 2005 March

Date Notes

27/07/2011 I was driving down the M4 going up a hill and lost power above 3000rpm in all gears

01/08/2011 Car was serviced by my local garage, who informed me, the computer had identified a blocked Diesel Particle Filter and glow plugs error on the diagnostics, details in serivce book of work carried out. Advised by my mechanic that I would need a forced regeneration of the DPF, which a BMW dealer would need to carry out.

16/09/2011 Car was put into BMW Cooper in Cobham, forced regeneration completed and highlighted the fact that it may only be temporary fix with the DPF and may require replacement. Was advised that the glow plugs needed changing and that the Turbo was noisy, however it was still working 100% but could go anytime, would not commit to when it would potentially give way

19/09/2011 Car went back into limp mode and would not go above 3000rpm

05/10/2011 I asked my mechanic to replace the turbo as a proactive measure, incase it blew and caused additional damage,
Synta Ed Oil
Oil filter
Air Filter
Turbo( Reconditioned and warrentied)
Breather
Breather Gasket
Breather Gasket Ring
Pressure Sensor

05/10/2011 I also asked my mechanic to replace the DPF filter with a new one, a 3rd party pattented offering (euro car parts) at a cost of £400 which he fitted

07/10/2011 Car still running in limp mode even after work carried out. Due to lack of diagnostics, my mechanic advised to hand over to a main dealer to see what the problem was, all avenues exhausted

13/10/2011 Booked car into BMW Sytner in Ascot, they performed diagnostic checks and Joel at BMW said the problem was 100% the DPF and a new one would cost £1751 fitted including diagnostics. I said to him are you 100% sure as if I spend this £1751 and it does not fix it, I could have used the pattented DPF at 1/3 of cost! Verbal gurantee but nothing in writing

17/10/2011 Car handed back to me, I was told the car was repaired and it was the DPF causing the problem.

18/09/2011 Drove the car to work, still the car had same problem above 3000prm, where the boost cuts out from the turbo and runs rough

21/09/2011 Car handed back to BMW Sytner Ascot for more diagnostic checks, identified air pressure sensor as the problem, fitted and charged £104 for completion of the job.

24/09/2011 Collected car today and it still drives exactly how it did before any of the work was carried out! Advised by BMW they now need the car again to do more checks as it could be something else and were blaming the turbo??? I said how can it that, when the problem was already there with the old turbo that BMW Cobham said still worked and had not blown???

Sorry for the long post guys but this is turning my hair white!!! £3500 already spent and BMW want more!

What a nightmare. What you need is a decent BMW specialist. The problem is that let's say there's an air leak: that will throw a number of fault codes including the MAF. Many inexperienced mechanics/technicians will replace the MAF and everything else that flags an error - but the problem is just an airleak.

The glowplugs are incidental to this saga - the car will run just fine with none working.

Something is tripping limp mode and the clue will be in the detailed error codes. What triggers limp mode? Is it hard acceleration? Is it just as the car changes gear? If it was a 535d I'd be suspecting a broken vacuum hose, but on the 530d that's not as common.

The dealer could have run a back pressure test on the DPF, takes a few minutes, that would be telling. Although the conclusion there could be either blocked DPF or the backpressure sensor. If you've had a replacement DPF then backpressure sensor is a top candidate.

Have you got part numbers for the bits the dealer replaced? There are a number of pressure sensors.

Hi Jason,

Thanks for the rapid response, much appreciated.

Ok, so here is what I can tell you additionally

Thanks for confirmation about the glow plugs, I suspected this.

Also, milage is about 112,000

1. Never does anything different when I change gear, it does on hard acceleration, I hold second/ third/ or fourth gear at 2000 rpm, then putting my foot flat to the floor, it pulls round positivley to 3200 but "not 100%" like it used to, but there is certainly boost pressure, plus at a stand still, it boosts round really quickly from idle to 4200 rpm (not to the redline, as not designed to stationary I guess?) So hopefully the turbo is good? I dont want BMW requesting £3200 for the privilage of more unessesary work :O)


3. The dealer did say they had serious back pressure issues with the car, but this was solved by fitting a "Booster Air Pressure Sensor" £38.70. The guy who did my turbo replaced a pressure sensor, which I think he said was the MAF, trade price was about £93.34 for a bosch unit, does this make sense? sorry no part codes of any replacements, I will see what I can dig out, as I suspect this wont end tomorrow.

Lets hope its not a horror story ending but so frustrating, as otherwise been a very good car.

Thoughts?

Thanks again

Hi,

Reading your symptoms it sounds like the MAF my Audi diesel did exactly the same. Unplug it and go for a drive it should drive worse with it unplugged if no change I would suspect it. You can clean them with carb cleaner as a temp

A friend of mine was having the same issue, the replaced everything (turbo/dpf/injectors/maf) nothing worked. Eventually the master tech determined there was a very fine crack in the exhaust manifold which was causing the pressure to drop and putting the car in limp mode.

Sorry to hear your having so much trouble !

My car suffers the same symptons and has been laid up for the past three weeks due to work commitments
As yet I have not had a chance to look at the car or have the car looked at,
Though from the work you have had done, seems to have exhausted my list of things to check,

I only hope you get yours sorted and would be curious to find the cause ...............
Gee! What I used manage to do all night, now takes me all night !!
Found what I couldn't find!

Have a read here seems like a similar problem

Perhaps you could contact him to see if he found a cure? Also whereabouts are you in the uk?

I have an excellent Indy down here in Essex called PMW, give them a call or ask to speak to either Peter or Daniel. Google them and have a read you need to find a decent Indy with all the right test kit and knowledge to go with it. Otherwise you will continue to guess at a very large cost.

I wouldn't expect a cracked exhaust manifold to trigger limp mode.

As above you'll know if it's a cracked exhaust manifold by the smell of exhaust fumes inside the car.

Forza West in Chepstow, he is a BMW Master Tech and really knows his stuff. Really good rates too. Google Forza West Chepstow and it will come up. Well worth the trip up the M4

Are there any new fault codes since the replacement of the parts.

Also if you have had a new DPF fitted & not registered, the car will think that it still has the old(blocoked) DPF on. Registration will tell ECU you that new DPF fitted & is all clear, thus telling all other sensors everyting is now ok.
