Are you familiar with how different a diesel car drives to a petrol? This is a BMW engine that is very good in terms of reliability. I'm not trying to sound flippant but I suspect there is nothing wrong. Drive a merc c class or vaux vectra and you will see the same thing, turbo lag.......... I had an SD as a loan car and it was a bit leggy,

If there are no codes then the ecu will not have stored a fault.

How long have you had the car.?

Yeah Its the first diesel I have had after two petrol minis, but I'm familiar with the fact it drives differently. I've had the car for 15 months and it's always been very responsive and quick off the mark but something has changed in the way it's running. It's been so bad a few times that it's stalled! Plus the other day I tried to pull away at a roundabout and there was about a 2 second delay in the car actually accelerating! Not safe when you're trying to pull away in busy traffic!

Fair enough if you have had the car for 15 months, I thought I would ask. If there are no codes stored in the ecu then the car is not showing any fault. However, it could be a be crap fuel, perhaps a dirty fuel filter.

If its an intermittent fault in something like the bsi or the abs ecu, a standard code reader may not pick it up.

I'm not sure for BMW, but at Peugeot we have a pps/diagbox on a laptop which you can read exactly every fault and do sensor tests etc. Something that a code reader won't be able to do
