Thread: TD5 Auto Question

How much throttle are you giving it?, they have a long stroke accellerator and you will have to put your boot into it a lot more than your petrol cruiser

Sounds about right, re turbo as it doesn't spool up until around 2000 rpm, coupled with the auto box they can be slow off the mark if you are not giving it the berries

There is turbo lag under 2k (about 2200 is peak torque when you should really feel it kick in), but the auto box will mask this at lower revs. The raw capacity of 2.5 L trying to move 2.5 tonnes uphill means its relying on the turbo. The engine ecu will work out the fuelling and boost, but to really get going it seems to work this out better if you give it full boot from standing start rather than from rolling start or progressively increasing. If its really sluggish could be another issue. Inter cooler, pipe work or EGR could need checking?

Check your MAF (Mass Air Flow) sensor.
I had similar symptoms and a clean with MAF cleaner retured everything back to normal.

Thanks for your replies. I think you are right, mabye i`m a little too gentle! I will also clean the MAF and see if it makes a difference... cheers

If the MAF clean doesn't fix the problem, disconnect it and see if that makes a difference. If it does the MAF has probably failed. The MAF output can be tesed with a Nanocom or similar device.

I had the same problem it ended up being the oxygen flow/pressure sensor on the inlet manifold; changed that and it was a new machine...

I am not disagreeing with previous comments but when I first got my D2a TD5 I thought it was a bit sluggish but when I 'learned' how to drive it it was a whole different vehicle.
I was initially very light on the throttle but I soon learned that a bit more of the right foot made a BIG difference.
Hope you sort it out. They are nice vehicles.

While the suggestions above are valid, don't fall into the trap of randomly replacing sensors in the hope that you'll fix a problem. It's a sure fire way to turn a Td5 into a money pit.

Have a look here and you should find a member nearby who has Nanocom:

You'll have to send a PM via the forum to the name listed on the map to get in touch.

If you can prevail upon someone to check for engine fault codes, and to record fuelling inputs for a 5-10 minute drive you'll have a very good snapshot of whether the engine is running correctly. Members will be more than happy to help interpret the "tea leaves".

cheers
