Hi guys i am used to driving a 3.0 v6 but just bought a 2.5td. Now i know its not going to be anywhere near as fast but the diesel doesnt seem to have any power until about 2500 revs.   is this normal? i know there is the problem of turbo lag but it seems rather extreme. Also when i take my foot off the accelerator pedal the eml flashes on the off any ideas what that could be or do i need to get the fault codes read Is there anything i can do to try and give it a bit more power in the low revs? dont really want to be driving around at over 2500 rpm all the time.

Detuned in the Omega, to around 125bhp. If a manual, can be chipped back to full BMW spec

I would start with waste gate blocked, meaning its taking more revs before it starts boosting

First do paper clip test and tell us all faults that could you read..

How or where do i get that done?

I will do that in the morning

2.5TD Manuals arnt that bad tbh even thougth detuned. Depending how old it is not all of them can be papercliped (from experience). I would do the Diesel Magic trick and or suspect the MAF.

Drop a PM to Omegatoy or TheBoy

As there are various types of chips available, some plug and play some need soldering in.

But only chip if its a manual, if an auto you need to drop in the stronger AR35 from 3.0/3.2

I've had my TD 14 years, and, yes it was sluggish compared to the 3.2, however, now it is chipped and with an AR35 box, it has put a smile on my face.

Simple things first:
1. PROVIDED that your coolant system is in good shape, clean, flushed, and filled with GM red antifreeze 50/50, remove the viscous fan, if fitted.
2. Check the rubber (possibly braided) pipe from the centre bottom of the air intake manifold to the electrical gizmo (an expert will remind me what this does ) next to the power steering reservoir. This pipe needs to be clear and have no splits anywhere.
3. If service history not known, or in any case, give it a thorough service, oil change, GM 10W-40, oil filter, air filter, and fuel filter. Before connecting the latter, fill the housing with Diesel Magic (about £6.50).
Experience by OOF TD owners has demonstrated that oil changes should be done every 3000 miles on this engine.

Report back if it is still down on power.

Boost sensor ... IIRC ...

The lump's de-rated to 128 BHP in the Omega.

'Plus 5' chip sends it back to BMW design spec of 143 BHP plus 5%; so then around 150-ish horses.
Turbo also kicks in earlier at around 1250 RPM
