525d Power Lag

OH and..happy motoring TJ....those wheels look well...savage...........I miss my bemmer even more...

220miles on a 525tds.....love to hear that...love to know what been done to her

Right, got car back from dealer today and got talking to technician. Denishogan and BMWCare you were very close, apparently it was a vacuum hose which had spilt and worked itself loose from the EGR valve, also there is a rod leading to the turbo which had seized.

So a new hose was fitted and the rod unseized. I also got a print-out from the GT1. There were unrelated faults which were dealt with and cleared. So the cars power is back to normal with the ability to pull tree stumps out of the ground!!! A good recommendation there boys! Thanks.

@ jrafferty: 220k - nice!  I love seeing cars with big miles.

Mine drives like a 60k car too - a testament to the previous owner. Cheers Oisin!

The 530d aint more sophisticated than a 525d but it should definitely have more grunt than mine. These 2 motors have the same engine model code. Only difference is obviously capacity and the resultant output in power and torque 163bhp for mine and 184bhp for the 530d, these are '02 figures of course. The latest models are well up again on this.

There's a definite problem alright with the pick-up in mine between 1 and 3 rpm, for since i've had the car, it hasn't lagged like this before.

Someone mentioned earlier, a 530d pinning you to your seat when accelarating, this thing used to do the same before this lagging problem. 

Interesting though, when I booked the car in with local BMW dealer today, (who has a GT1 diagnostics tester) and explained the problem, they asked if I had the replacement Mass Air-Flow Meter programmed in when fitted. Not realising this needed to be done, they pointed out that they would do this first before running the diagnostics test.

Incidentally, BMW diesel badging was first td, then tds and now 'd'. The latest 2.5'd' has an output of 177bhp and the 3.0d 231bhp.

In hindsight TJ, my previous 2.5TDS never gave any trouble after 208k when I changed for this one, a real bulletproof motor!   

Well it does feel torquey below the power band, i.e you can start in 2nd and all that but the peak power or at least the start of the peak curve comes on just above 2k rpm and then you feel the boost.

The 530d would be a much more sophisticated animal!

I think you mean all the noise alex!

@ T.J, that is magnified even when it is chipped, i recall mine especially in 1st pulling away from a junction, if you let clutch out fully at say 1100rpm and floor it it would pause for a second, climb to 2200 slowly then whoosh... to around 4k ish..

@ Denis, hmmm 6 cyl, possibly a scaled down 530d so. Did you manage to do something about that timing chain..

Sure if you want a hand let me know ill be around,
