Power

Quick question and there may be loads of answers, my TD5 feels like it's a bit down on power, is there a common thing or could there be a hundred things? Thanks

1. Oil in the ECU plugs;

2. MAP and or MAF clogged up with muck and gunk;

3. Air filter clogged to fûck;

Try those first and see how you get on,

It could be because they are all slow and down on power, especially the auto's like mine, but that's how it is!

Thanks folks, will start having a look at it

Mine will beat most other vehicles away from the lights,is an auto ,but think it has been chipped.Also tries to spin the wheels in the wet and tc comes in-like a racing car compared to my old 300tdi manual

Really, can't imagine that even the V8's would spin four wheels in the wet?

Quite a surprise when it first happened,odd feel to the steering and yellow light on dash,and took longer to pull away-thought what the hell is bust now.
Can join 30mph traffic from a standstill no problem,pushes you back in seat under full welly-love it

Check the small rubber pipes to the turbo boost modulator. Out of the 3 I had one split and one holed.

i have to say mine is the same, ive done the egr blank, KnN pannel filter, decat, no center box and it goes like stink from a stand still and will pull a house down.
its touching 200k as well.

Disconnect the sensor in the airbox,

If it fails, it seems to restrict the turbo boost to 1 bar

I did mine, and what a difference, never replaced it, they're pretty dear, but no ill-effects at all ( or engine management lights either)

cheers

If you mean the MAF, they are there for a reason, you are likely to be using more fuel then necessary.

The sensor in the airbox measures temp and pressure of ambient air and is referred to as the AAP (Ambient Air Pressure).

These are very cheap especially if you buy the same part but with a Mini label on it. About £25 from memory.

Must investigate that,

I found a thread on here were they were quoted at £200 for a 4 pin, and around £90 for a 3 pin mini one,

tbh i never check fuel mileage, fill it, drive it, and fill it

thanks for the info Big lad
