535d seems slow

54 posts in this topic

Hi, 

I'm New to the forum. In an ideal world i would have liked to introduced myself by helping others but unfortunately I have an issue myself at the moment, or what I think is an issue. 

I have an e60 535d lci. From what I can gather from forums etc they are supposed to be fairly rapid. I've owned it for nearly a year and seems to be ok but when I've come into contact with other vehicles that I should surely be faster than, I can honestly say I'm not.

One day I had a 66 plate skoda octavia vrs tdi behind me, I know those things are 180bhp but when I tooled my car to overtake another he followed and I couldn't get away. Another day I was behind a chipped etc astra cdti, these things are 200bhp ish when messed with, he saw me in his mirror and nailed it, I followed but would have taken me quite a bit to overtake and I don't like going stupid speeds where you get banned. In another instance, a friend of mine has a 520d mapped to 220 ish, he was behind me one day and I couldn't shake him from 20-70mph

I suppose what I am getting at is, why do cars like this do so well against my derv? Im pretty certain that my turbos are both working as they should, I have replaced the vacuum hoses when I first got the car as they were shot, so the problem doesn't lie there. 

Maybe I don't have a problem but I don't know anyone with a 535d to ask. Any help would be appreciated.

Thanks

Get a scan for any logged error codes or buy a cable kit to DIY investigation, pays for itself the first time you successfully use it but expect a bit of a learning journey (no magic bullet sadly).

Or even easier,take it to a reputable indie and explain your worrys.a good one will investigate it properly

or you could roll n road it or whatever they call it and see if any of your ponies are missing...

I'm a mechanic so ive scanned it, it does show exhaust backpressure codes but I this is related to the dpf being cut out before I got it. I don't think it's been remapped to remove the dpf as it still trys to regen and I have seen the dpf light once before. I don't think it's related to this because the restriction is removed from the exhaust. Could be wrong by though.

The amount of things it could be would cost a fortune if you tried to eliminate it.lots of different problems do not show on cheap scanners..do you understand how this particular car works ?

When my 535d want running 100% I've played with a few motors..focus rs. Or st all spoilers and bonnet vents...about the same....a new golf gttd I was faster but not a lot....anyway I lost all low power and have had some work done on the car..it's 100% standard by the way and would without doubt now pull away from both of these with ease.....

Read my loss of low power thread  and it will show you the things I've replaced to get it right.

Yes I understand how this car works. As stated, I am a professional mechanic, dont use cheap scanners, codes stated were shown on snap on verus and delphi. The car has power low down, as I say the turbos are both doing their job at the right times, the affectivenes of them could be questioned though. So far I have not looked into the issue as such I just figured I'd ask people who also own the 535d so called monster.

I guess the real question I was asking is, is it normal for lower powered cars such as the ones in the opening post to be so close to mine, I once could not pass a new golf gtd but he could not get away either. 

Thanks

"Doing em" haha, just how I think. Egr is clean. I did timing chain when I got it. All sorts got replaced and cleaned at the time. Not checked boost hoses, can't hear any hissing noises, replaced the seals on the lower hose due to the usual oil leak.

Hmm. Don't like the idea of paying someone else to fix my car, hasn't so far and don't plan on doing so in the future either. When I'm at work next week I'm going to vacuum test the actuators etc. Does anybody know what specs these should be at on this particular car?

Think RCAddicted had a similar problem, and his needed both pressure converters replacing.  These were also an upgraded part, so you need a new bracket for them as well.

 

No.    Description        Supp.    Qty     From      Up To     Part Number    
01    PRESSURE CONVERTER        1            11747796634
02    PRESSURE CONVERTER        1            11657793032            
05    Holder                1            11657792241

My brain was pointing me towards the pressure converters. Might just replace them both and have done. Were the converters upgraded on the lci too?

Actuators also might need looking at,not just pressure test but also start and finish length on push rod...I'm far from an expert by the way...the BMW specialist I use plugs the lap top in and does a functionality test...looks superb

OP's car is LCi, the above diagram is for pre-LCi. Both pressure converters (#1) are identical (part #: 11658509323) and bracket (#6) 11657811834

Stick it on a rolling road and see what HP you're getting and look at the power curve etc.

Ah, that may be a problem lol. I appreciate the offer, thank you. If there's nobody closer willing to test mine, I'll have to put it in the rolling road. Maybe even just replace the pressure converters, they are original and do seem to go wrong quite often from what I can gather.
